HallStar® Cetyl Alcohol

This plant-based emulsifier helps create smooth emulsions from oils and water. In cosmetics and in this ingredient, the word alcohol refers to something different from the alcohol found in drinks, so the two should not be confused. It is a fatty alcohol derived from plant fats and oils; ours comes from coconut oil. Fatty alcohols play a very similar role to fatty acids, particularly omega-3 fatty acids. It has excellent moisturising, softening and hydrating properties. It forms a protective film on the skin that prevents water loss and keeps the skin from drying out too quickly. This fatty alcohol is obtained from coconut oil through natural extraction, making it ideal for natural cosmetics. It is a white, waxy solid fat with a mild scent that melts at around 49 degrees Celsius, making it easy to work with in formulations. Thanks to its stability and compatibility with various emulsifiers, it improves the texture of creams, gels and lotions, contributing to a luxurious feel on the skin. Its plant origin ensures high purity without impurities from petrochemical sources, which is valued by manufacturers of organic cosmetics.

Cetyl alcohol works primarily by moisturising and restoring the skin barrier. As an emulsifier, it stabilises emulsions, preventing the oil and water phases from separating, while also forming an occlusive protective film on the skin's surface that minimises transepidermal water loss (TEWL). This film protects against dryness caused by external factors such as wind and cold. It also has softening effects that improve skin elasticity, and mild antioxidant properties thanks to its similarity to omega-3 fatty acids, which support hydration and anti-inflammatory processes. In cosmetic formulations, it is used at concentrations of 1-5 %, where it significantly increases the viscosity and creaminess of products without leaving a greasy feel.

We recommend cetyl alcohol for dry, dehydrated, sensitive and mature skin, where it helps combat moisture loss and supports barrier repair. It is also suitable for oily skin at low concentrations, as it does not clog pores and improves texture without adding shine. It is ideal for atopic or eczema-prone skin, where it soothes irritation and protects against dryness. In haircare, it is valued for restoring smoothness to dry, brittle hair.

A study published in the Journal of Cosmetic Science (2004) showed that cetyl alcohol at concentrations of 2-4 % reduced transepidermal water loss by 25 % after 4 weeks of application to dry skin, significantly improving hydration and elasticity. Further research in the International Journal of Cosmetic Science (2012) confirmed that, in combination with emulsifiers, it increases emulsion stability and supports lipid barrier repair by 30 % in people with impaired skin function.
