What is cetylstearyl alcohol?

Cetylstearyl alcohol is a fatty alcohol derived from vegetable oils (such as coconut oil or palm oil) or sometimes synthesized. Unlike denatured alcohol, this ingredient is not irritating or drying to the skin; it is, on the contrary, used for its emollient and thickening properties. In cosmetics, cetylstearyl alcohol is commonly added to creams, lotions, and balms to stabilize and improve the texture of products, giving them a smooth and pleasant consistency to apply. Its moisturizing and softening effect makes it ideal for care products intended for dry or sensitive skin, as well as for hair products.

Any side effects?

Cetylstearyl alcohol is generally well tolerated, but certain adverse effects may occur, particularly in cases of very sensitive skin or a reaction to a product containing a high concentration:

1. Skin sensitivity or irritation : Although rare, some people may experience mild irritation or redness if sensitive to fatty alcohols. It is recommended to perform a skin test before prolonged use.
2. Comedogenic risk (rare) : For very oily or acne-prone skin, excessive use of products containing cetyl stearyl alcohol could occasionally clog pores. It is advisable to use it sparingly or opt for lighter products.
3. Buildup on hair : When used in hair care, frequent use may lead to residue buildup, especially on fine hair. A clarifying shampoo can be used from time to time to avoid this effect.
4. Rare allergic reaction : Allergic reactions to cetylstearyl are rare but can occur, manifesting as redness, itching or a burning sensation. In the event of a reaction, it is advisable to rinse the skin and stop using the product.
5. Interference with other ingredients : In some cases, cetyl stearyl alcohol may interact with certain ingredients, affecting the stability of the formulation. However, this risk is minimal in well-formulated products.
