When it comes to skincare, numerous ingredients claim to offer a wide range of advantages. One particular group of ingredients that frequently feature in skincare formulations is fatty alcohols. Although the term "alcohol" may concern you, fatty alcohols have distinct characteristics that differ from drying alcohols often associated with skincare products and can actually benefit your skin.
In this blog, we will delve into the nature of fatty alcohols and explore their popular usage in skincare products.
Understanding Fatty Alcohols:
Fatty alcohols belong to a category of long-chain alcohols obtained from natural sources like coconut oil, palm oil and can also be synthesised in a lab. Unlike drying alcohols such as ethanol or denatured alcohol, fatty alcohols are non-irritating and non-drying on the skin.
The Role of Fatty Alcohols in Skincare:
Emollient Properties: Fatty alcohols function as emollients, meaning they soften and soothe the skin. By forming a protective barrier on the skin's surface, they help seal in moisture and prevent water loss, ultimately promoting hydration.
Improved Texture: Fatty alcohols contribute to the creamy texture of skincare products. Their waxy nature aids in thickening formulations, enhancing the spreadability and consistency of creams and lotions.
Moisturisation: With occlusive properties, fatty alcohols create a layer on the skin that reduces water evaporation. This retention of moisture helps keep the skin hydrated and reduces dryness.
Skin Barrier Repair: Fatty alcohols actively support the function of the skin barrier by replenishing lost lipids caused by factors like harsh weather (hello, UK!) or excessive cleansing. They aid in restoring and strengthening the skin's natural protective barrier, contributing to overall skin health.
Distinguishing Fatty Alcohols from Denatured Alcohols:
As mentioned, fatty alcohols are long-chain alcohols derived from natural sources or synthetically produced. They are frequently found in skincare products for their soothing and moisturising properties. Fatty alcohols like cetyl alcohol, stearyl alcohol, and cetearyl alcohol effectively soften and soothe the skin while forming a protective barrier to prevent moisture loss.
In contrast, denatured alcohol refers to ethyl alcohol obtained from fermentation, mixed with additives. Denatured alcohol is also often used in cosmetics and skincare products (such as toners or sprays).
