Lanolin is a waxy substance produced by the sebaceous glands of sheep, secreted into their wool to keep the fleece water-resistant. In its raw form it is known as adeps lanae, or wool wax. Refined and purified, it becomes one of the oldest and most widely used emollients in skin and hair care — including in our beard balms.
It is completely renewable, harvested as a byproduct of shearing, and the sheep are not harmed.
What Does Lanolin Do?
Lanolin is an emollient and an occlusive. It softens the skin, and it forms a barrier that slows the loss of water through it. It can absorb up to twice its own weight in water. Its structure is a mixture of fatty acids, esters and alcohols rather than a triglyceride oil, which is why it behaves so differently from a plant oil on hair and skin.
On a beard, lanolin conditions the hair, adds weight to unruly growth, and helps the skin beneath retain moisture. It is a common ingredient in beard balm, lip balm and skin creams for exactly this reason.
A History Reaching Back Millennia
Lanolin's name comes from the Latin lana (wool) and oleum (oil). Evidence of its use stretches back thousands of years. Ancient Egyptians are said to have worn blocks of scented fat on their heads that melted in the sun and spread across their skin. Pedanius Dioscorides, the Greek physician whose De Materia Medica catalogued medicinal ingredients in the first century AD, recorded wool grease among them.
High Purity Grades of Lanolin
For most of its history lanolin was extracted by boiling wool by hand — slow work with poor yield. In the late 1800s a German chemist, Otto Braun, developed a method of spinning and washing the wool to produce a purified version, which he named lanolin.
Early purified lanolin was still earthy-smelling and difficult to spread. Refinement techniques developed through the twentieth century produced the odourless, tasteless, hypoallergenic grade that made its way into medical and cosmetic products worldwide. One of the first modern skin creams — the product now known as Nivea — was built around it more than a century ago.
The Chemistry
Lanolin is a light yellow compound built from complex waxy esters, formed from the combination of lanolin acids and alcohols. It has been estimated that many thousands of distinct ester combinations exist within it. Different fractions behave differently, and derivatisation — chemically transforming a compound into a related one — lets manufacturers isolate the properties they want for balms, creams, oils and salves.
The extraction process itself is straightforward in principle. Unwashed wool is boiled with added salt to improve the yield. The liquid is filtered, leaving an off-white solid: pure lanolin. This is then washed to remove residual dirt.
Why We Use Lanolin in Beard Balm
Lanolin conditions beard hair and the skin beneath it. It adds body, helps tame unruly growth, and holds moisture in — which is what a beard needs, particularly in the early stages of growth when the skin underneath tends to feel dry or itchy.
We use it alongside shea butter and candelilla wax in every Cutthroat beard balm.
Lanolin FAQs
What is lanolin?
Lanolin is a waxy substance secreted by the sebaceous glands of sheep into their wool. It is harvested from shorn fleece, purified, and used as an emollient in skin creams, lip balms and beard balms.
Is lanolin vegan?
No. Lanolin is an animal-derived ingredient. It is not vegan, though it is vegetarian by most definitions, since the sheep is not harmed and the wool regrows.
Does harvesting lanolin hurt sheep?
No. Lanolin is a byproduct of wool-gathering. It is extracted from wool that has already been shorn.
Is lanolin the same as wool wax?
Yes. Raw lanolin is also called wool wax, wool fat or wool grease — adeps lanae in Latin. Refined lanolin is the purified form of the same substance.
Can lanolin cause an allergic reaction?
Some people are sensitive to lanolin, though modern high-purity grades are far less likely to cause a reaction than the crude wool grease of the past. If you have a known wool or lanolin allergy, patch test any new product on a small area of skin first.
What does lanolin do in a beard balm?
It conditions the hair, adds weight and body so the beard is easier to shape, and helps the skin beneath the beard hold onto moisture.
