Cholesterol molecule structure formula

Introduction: Cholesterol – more than just a blood lipid

Cholesterol is a natural component of our body – and also plays a central role in skin care. In the epidermis, it acts as a moisturizing factor and, in combination with other lipids, ensures a functioning skin barrier. However, the classic raw material of animal origin is increasingly controversial. The modern cosmetics industry is therefore turning to plant-based, semi-synthetic alternatives with optimized skin compatibility and better formulability. Welcome to the new era of cholesterol cosmetics!

 

 

Cholesterol in nature and its role in the skin

Cholesterol (INCI: Cholesterol) is a fat-like molecule that occurs naturally in all animal cells. It is particularly abundant in human sebum (skin oil) and in the extracellular lipid matrix of the stratum corneum—the outermost layer of our skin. In this lipid matrix, cholesterol, ceramides, and free fatty acids form lamellar (layer-like) structures that protect the skin from water loss and external influences.

Around one third of the lipids in the skin barrier consist of cholesterol and its derivatives, such as cholesterol sulfate or cholesterol succinate. They regulate the permeability of the skin, improve the absorption of other active ingredients, and influence the texture and stability of cosmetic emulsions.

 

 

Production and origin: From sheep’s wool to plant-based innovation

Traditionally, cholesterol was extracted from wool wax (lanolin), a by-product of the sheep wool industry. However, this process often involves the use of solvents and chemical extraction agents that can leave behind residues such as pesticides. This makes many consumers skeptical, especially in the context of clean beauty and vegan trends.

The solution: plant-based cholesterol alternatives

Evonik’s PhytoChol® technology represents a significant step toward sustainable cosmetics. Here, cholesterol analogues are produced semi-synthetically from plant-based raw materials such as GMO-free pine products. The result is skin-identical molecules with improved solubility, better penetration, and high purity.

Cholesterol USP/NF-PW(RB): Quality that convinces

In addition to plant-based alternatives, pharmaceutically pure cholesterol is also playing a growing role. An outstanding example is Cholesterol USP/NF-PW(RB). This high-purity variant complies with the standards of the United States Pharmacopeia/National Formulary (USP/NF) and thus offers maximum safety and purity – ideal for sensitive skin and medical-cosmetic applications. The fine powder is easy to process and is suitable for high-quality creams, emulsions, or liposomal systems. If you are looking for uncompromising quality, this form of cholesterol is the right choice.

 

 

Advantages of the new cholesterol cosmetics

The innovative cholesterol derivatives are true all-rounders:

Emulsion stabilizing: Promote the formation of lamellar structures.

Penetration-enhancing: Increase the effectiveness of other ingredients.

Barrier-strengthening: Support the regeneration of the skin lipid matrix.

Versatile: Ideal for day, night, and moisturizing care.

Clean beauty compatible: Free from animal ingredients, highly pure, and well tolerated.

Hair care & sun protection: Improve combability and protect against UV damage.
