Lanolin for Personal Care and Medicine

Wool wax is a natural substance, designed by nature to soften both skin and wool fibres, and to protect them against adverse weather conditions. The best known uses of refined wool wax products (lanolin and lanolin derivatives) are in medicine, cosmetics and toiletries, which build on these natural protective qualities. The wax is separated from the liquid using high speed centrifugation. It is then processed and refined through a number of processes, including:

  • reducing free fatty acids, soap and water content
  • eliminating contaminants
  • deodorising and bleaching

These steps can also be modified to achieve different grades of product purity.

Functions and Applications

Emollient properties of lanolin

The composition of lanolin resembles the intercellular lipids of the stratum corneum. This is the outermost layer of the skin, which consists of cholesterol, cholesterol derivatives and free fatty acids. These lipids play a crucial role in the skin’s moisture control. Under normal conditions, water continuously evaporates from the skin’s surface. Insufficient rehydration from lower epidermal layers leads to a dry, inflexible and brittle stratum corneum.

Bi-functionality of lanolin

Lanolin Alcohol’s water absorption capacity makes it an excellent sole emulsifier. Blended at 6 % into a petroleum jelly-based ointment, it can achieve a water absorption capacity in excess of 200%. Considering petroleum jelly has a close to zero water absorption capacity, this converts into a comparable water absorption capacity of almost 3000% for lanolin alcohol.

Anhydrous lanolin can absorb more than 200% of its weight in water (WW) to form stable water-in-oil (w/o) emulsions. It is also capable of redistributing this moisture to environments of low relative humidity.

In other words, it can both prevent moisture loss and rehydrate. This can be illustrated with a simple experiment.

Glass sheet experiment

By coating a sheet of glass with a thin film of lanolin and dipping it into a container filled with water, the formerly transparent wax layer grows increasingly opaque because of all the water it has absorbed. When the glass sheet is removed from the container and exposed to the air, the lanolin film gradually becomes transparent again as it releases the water via evaporation and dries out. Hydrocarbon-based emollients such as Vaseline or petrolatum do not possess this bi-directional water transport ability. Instead they form an almost impermeable occlusive film on the surface of the skin. Lanolin, as an auxiliary emulsifier, also helps to improve the smooth feel and silky texture of such oil-based systems.

Similarities between lanolin and human skin

Variations of the glass sheet experiment on the stratum corneum of human skin treated with lanolin have shown similar effects. In addition to the chemical similarity between lanolin and human skin lipids, other physical similarities have been discovered, such as multilamellar structures. These molecular aggregations strongly resemble the liquid crystal structures occurring in skin lipids. Lanolin-based skin-care products owe their superb emollient properties to the unique chemical and physical characteristics of lanolin.

Lanolin in cosmetics

Natural emollient

Lanolin’s beneficial effects on the human skin and hair have been known and valued by humans for thousands of years. The natural emollient is absorbed by the skin, restoring its correct moisture balance and softness without impairing natural skin functions. As such, it is an ideal and widely used ingredient for cosmetics, personal-care products and medical applications.

Emulsifying properties

Because of the polar nature of its compounds, lanolin has powerful emulsifying properties. This means that it can bind high amounts of water by forming stable emulsions.

By applying it to human skin as a cream or ointment, this moisture is distributed into the intercellular space of the stratum corneum, the outermost skin layer.

To prevent the intercellular water from evaporation, lanolin lipids form a semi-occlusive film on the skin and create a protective barrier.

The regained and stored moisture has a noticeable softening effect on the epidermis, as observed and confirmed by leading laboratories.

Natural all-rounder

The emollient care effects of lanolin and its derivatives are harnessed in a wide range of:

  • skin creams (such as Nivea® Creme, night creams, cold creams, barrier creams and vanishing creams)
  • ointments
  • sunscreen lotions.

However, the complex composition of lanolin makes it a real natural all-rounder.

  • In soaps it acts as a superfatting agent, minimising dehydration of the skin.
  • Lanolin oil is used as gloss-enhancing agent in lip glosses.
  • In lipstick it can function as a crystal inhibitor.
  • In shampoos and shower gels, as a conditioner.

Other cosmetic applications

Lanolin is also widely used in:

  • foundation creams and other skin-cream products as an emulsifier, stabiliser, emollient and skin moisturiser;
  • oil-based skin lotions and cleansing oils as a skin moisturiser and to control viscosity;
  • toilet soaps as a superfatting agent, minimising the dehydrating effect of detergents, and to retain perfume;
  • aftershaves as a skin moisturiser and to control viscosity;
  • nail polish removers to prevent the defatting of the surrounding skin;
  • lipsticks and eye make-up as a film modifier and crystal inhibitor, for more uniformly dispersed pigment;
  • hair dressings and shampoos, as a conditioner against drying, scaling and brittleness of the hair shaft;
  • hair sprays, as a plasticiser;
  • hair bleaching agents, as a pH-stable emulsifier.

Lanolin in pharmaceuticals

Superb skin protector

As well as being well tolerated by the body – it is approved for uses in ophthalmic emollients and as a food additive in chewing gum bases – lanolin is also of medical interest. It can act as a carrier for pharmaceutically active ingredients that have to be transported into deeper layers of the skin. In burns dressings, lanolin supports the wound healing process and enhances dermal repair.

The use of lanolin acids in topical products for cutaneous infections (e.g. acne) and deodorising toiletries ultimately underlines the versatility of lanolin and its derivatives. Besides emollient and moisturising characteristics, lanolin’s protective function includes antimicrobial and disinfectant activity on human skin.

Medical applications

Lanolin is widely used in:

  • ointment bases, burns dressings and wound sprays
  • as an emulsifier, stabiliser and emollient
  • to support the wound healing process
  • to deliver active ingredients through the skin (trans-dermal);
  • pigmented medications (e.g. zinc oxide), as a dispersing agent;
  • topical products for cutaneous infections (e.g. acne) and in deodorising toiletries, as an anti-microbial and disinfectant.

Other applications

Lanolin is also used in:

  • ophthalmic ointments, as an emollient with high physiological compatibility and low irritation potential;
  • suppositories substantial base, as a carrier for active ingredients;
  • surgical adhesive tapes, as an impregnating agent, plasticiser and skin-suited stack enhancer;
  • chewing gum bases as a food additive (physiologically compatible emollient);
  • pre-blended combinations for specific purposes, such as absorption bases.

LANIS Lanolin Anhydrous

Approximately 97% of the pale yellow substance is composed of a complex mixture of esters that are formed by in-situ condensation reaction of high molecular weight (MW) alcohols with high MW fatty acids. The class of esterified lanolin alcohols can be divided into three main sub-groups:

  • steroids
  • triterpenoids
  • aliphatic alcohols.

The lanolin acid fraction consists of various branched and unbranched acids and hydroxy fatty acids. The remaining 3% of the mixture is made up of free lanolin alcohols and small amounts of free fatty acids, hydrocarbons (paraffins), water and ash. Because lanolin is a natural product, the exact composition can vary slightly within a tightly controlled limit.

Lanolin is soluble in organic solvents such as diethyl ether, chloroform and chloroform/methanol mixtures, but poorly soluble in ethanol. It does not dissolve in (but is mixable with) water, forming stable oil-water emulsions.

Product features and applications

Anhydrous lanolin has a water absorption rate of more than 200% of its own weight and reluctantly forms water-in-oil (w/o) emulsions. Due to its excellent emollient and emulsifying properties, lanolin restores the skin’s correct moisture balance and softness without impairing natural skin functions.

Lanolin is widely used in cosmetic and medical skin creams and ointment bases, as well as a range of other products. The refining process can be customised according to country and intended use. This flexibility is necessary to meet the different requirements of pharmacopoeias throughout the world. It also allows the supplier to offer economical solutions for technical applications (Link >) that do not need to adhere to rigid pharmaceutical standard

Lanolin Alcohol

Lanolin alcohols are the most powerful surface-active natural components of wool wax products. They make up around 50% of the total weight of lanolin anhydrous, in which they are chemically bound in ester compounds. The alcohol fraction is obtained by using an alkaline treatment on the lanolin and then removing the released soaps. It is refined further via a multi-stage molecular distillation process, which improves colour and odour. This produces a purified, semi-crystalline and practically colourless wax.

Composition

Lanolin alcohol is lanolin’s primary derivative. It consists of a refined mixture of high molecular weight (MW) alcohols (the mean MW is 370).The main fraction (75%) is composed of sterols and triterpene alcohols, of which cholesterol is the largest individual component (36%), followed by lanosterol, agnosterol and their dihydric derivatives.

These alcohols are closely related to the physiological lipids of the stratum corneum, the human skin’s ‘horny layer’. This results in the excellent epidermal compatibility of lanolin alcohols in skin-care products. The alcohol mixture also contains branched and unbranched aliphatic alcohols in both mono- and dihydric forms. To avoid surface autoxidation, traces of butylhydroxytoluene (BHT) are added at the end of the refining process.

Product features and applications

Free lanolin alcohols have a more potent surface activity than the esters in which they are usually bound as a result of their higher polarity. They are the source of the high water absorption capacity of lanolin anhydrous. Free and refined lanolin alcohol is an even more efficient absorbent, capable of taking up a larger multiple of its weight in water (WW). This makes it one of the most powerful non-ionic water-in-oil (w/o) emulsifying agents available.

Lanolin alcohols are produced from only the highest-grade wool grease, to meet the numerous pharmacopoeias‘ strict requirements. The waxy substance’s pale colour and mild scent makes it ideal for use as an emulsifier and stabiliser in cosmetics and toiletries, where whiteness and neutral odour are important. One of the best-known moisturisers containing lanolin alcohol is Nivea® Creme, which has relied on its emollient effect for nearly a century.

When blended with cetearyl alcohol as an additional stabiliser, and mineral oil or petrolatum to change consistency, lanolin alcohol acts as a functional component in so-called absorption bases. Because lanolin alcohol’s emulsifying properties are stable in a wide pH range, it can be used in acidic and alkaline w/o emulsions, such as hair bleaching agents. Another important property is lanolin alcohol’s ability to help the wound-healing process. As a result, it has numerous applications in medical and pharmaceutical products. In addition, lanolin alcohols can function as carrier systems to deliver pharmacologically active substances through the skin.

LANIS AL EP PLUS - Lanolin Alcohol Pharma Grade

Lanolin alcohol has been used in absorption bases since the early 1900s. Blended petrolatum and lanolin alcohol bases can be applied to injured tissue to help maintain its physical state without affecting the healing process. Lanolin alcohol-based dermal patches and topical products are effective at delivering medicinal drugs, such as antiseptics and antibiotics, to body tissues. These range from ophthalmic ointments to anti-infection dermatological emulsions.
LANIS AL EP PLUS is designed to meet the most advanced requirements – both in consumer safety and functionality. 

Lanolin Alcohol EP Plus is an ultra-pure grade of high cholesterol lanolin alcohol suitable for a broad range of medical and cosmetic applications. Due to dedicated removal of impurities and potentially allergenic components, LANIS AL EP PLUS provides interesting opportunities specifically in formulations for sensitive skin. LANIS AL EP PLUS is the only grade available on the market that meets the EU’s rigid foodstuff standards for residual contaminants. It is a patented, ultra-pure grade emulsifier and emollient with antimicrobial properties. It’s a high quality, pharmaceutical-grade lanolin alcohol, suitable for a broad range of medical and cosmetic applications.

Lanolin Oil

Lanolin oil is the liquid phase of pharmaceutical-grade lanolin, from which it is isolated by low temperature fractional crystallisation. It  is used most commonly in moisturising skin and haircare products, which make the most of its emollient qualities.

Product specifications and applications​

Chemically speaking, lanolin oil is similar to lanolin anyhdrous, except that it has been enriched with lower molecular weight (MW) esters and branched-chain hydroxy compounds. The exact composition depends on the solvent used for crystallisation; for instance, in the case of extraction via isopropanol, lanolin oil has a mean MW of 360. Lanolin wax is the solid form of the separation process.

The clear, amber-coloured oil has the known qualities of anhydrous lanolin and is easy to handle because it is fluid at room temperature. Liquid lanolin is a common emulsifying agent. It has a high spreading coefficient and is a very good emollient. It is completely soluble in mineral and vegetable oils, without precipitation.

Lanolin oil is often used in moisturising skin and hair-care products. It can also be found in oil-based skin lotions, bath and hair oils and numerous cosmetic emulsions, guaranteeing low viscosity and tackiness.

Lanolin Ethoxylated

Lanolin ethoxylated belongs to the class of ethoxylated lanolin derivatives. The purified product is a flaky wax, yellow to amber in colour, and with a faint, characteristic odour.  LANIS PEG 75 consists of polymer chains with a mean length of 75 ethylene oxide units (monomers), which are chemically linked to ester compounds of highest-grade lanolin anhydrous through condensation reaction. The resulting macromolecules have a mean molecular weight (MW) of about 4000 Dalton, and consist of a lanolin ester core and a surrounding polyethylene oxide chain.

Product features and applications

LANIS PEG 75 is a completely water-soluble derivative of anhydrous lanolin as a result of ethoxylation. The surrounding polyether chain allows water molecules to assemble a hydrate cage around the unpolar and otherwise virtually insoluble lanolin ester core. The resulting solutions (both aqueous and ethanolic) are crystal clear at any concentration, non-ionic and compatible with most physiological electrolytes, e.g. sodium chloride. The dissolved lanolin derivatives are stable over a wide pH range of 2 – 10.

LANIS PEG 75 is a multifunctional surfactant with solubilising, emulsifying, wetting and soft detergent-like properties. It can be used in clear liquid cosmetics and personal care where viscosity must be controlled, such as in aftershaves and cleansing lotions. It minimises the defatting effect of detergents on skin and hair without impairing their cleansing ability. Ethoxylated lanolin derivatives are potent solubilisers of insoluble materials such as lanolin, lanolin oil and hydrocarbons. It is also used in stable low-viscosity micro emulsions of insoluble pharmacological compounds for spraying onto wounds or burns.

Derived products

In addition to its solid anhydrous form, lanolin ethoxylated is also available in a 50% aqueous solution. The clear, bright yellow viscous liquid has the same characteristics as anhydrous lanolin, with the added advantage of already being dissolved and therefore easier to handle.

LANIS PEG 75 - Lanolin Ethoxylated PEG 75

LANIS PEG 75 – Lanolin Ethoxylated PEG-75 can be used as a solubiliser for fats, as a spreading agent for tar in skin-care products, and with amphoterics and other mild tensides in baby shampoos. LANIS PEG 75 is ideal for soaps and detergent cleansers such as shampoos, foam baths and shaving foams. In small concentrations it acts as a clarifying agent in aqueous systems such as clear shampoos and gels. It can also be used in skin-care creams and lotions, hair-styling products and nail varnish removers.

Lanolin Hydrogenated

Because hydrogenated lanolin is composed primarily of lanolin-derived alcohols, its chemical and physical characteristics strongly resemble those of lanolin alcohol. It is a white, slightly pasty and virtually odourless solid with an exceptionally low acid and saponification value. Hydrogenated lanolin is a complex mixture of fatty alcohols obtained by hydrogenating lanolin anhydrous.

By reacting with molecular hydrogen at high pressure and temperature in the presence of a solid-state catalyst such as raney nickel, lanolin esters are cracked and reduced to alcohols and hydrocarbons. Depending on the exact reaction conditions, up to 90% of the yielded product consists of monohydric and dihydric fatty alcohols, with the rest made up of hydrocarbons (paraffins) and residual ester compounds.

Product features and applications

Hydrogenated lanolin keeps the emollient and adhering properties typical of refined wool wax products, but lacks their characteristic odour, colour and tackiness.

As a surfactant compound, it strongly reduces the interfacial tension of various oil-water systems. It’s therefore used as a good emulsifying agent.
For further applications, read about lanolin alcohols.     

LANIS HYD - Lanolin Hydrogenated

LANIS HYD – Lanolin Hydrogenated contains dihydrocholesterol, other hydrogenated steroids and some saturated alcohol. It is often used in cosmetic and pharmaceutical products because it’s virtually colourless and odourless. It is used in cosmetics such as face packs, make-up foundation, lip gloss and lipsticks.
