Custom Q&A

What is cetearyl alcohol?

Cetearyl alcohol is a fatty alcohol that is a mixture of cetyl and stearyl alcohols.

How is cetearyl alcohol derived?

It can be derived naturally, such as from coconut fatty alcohol, or made synthetically.

What are the properties of cetearyl alcohol for the skin?

Cetearyl alcohol has emollient properties, providing a softening and smoothing effect on the skin.

What is the difference between cetearyl alcohol and skin-damaging forms of alcohol?

Unlike skin-damaging forms of alcohol like SD or denatured alcohol, cetearyl alcohol is gentle, safe, and good for the skin.

What are the additional uses of cetearyl alcohol?

Cetearyl alcohol can be used as a carrying agent for other ingredients, alter the thickness of a formula, or influence the foaming capacity of a cleanser.

What is the solubility of cetearyl alcohol?

Cetearyl alcohol is not soluble in water but is soluble in alcohol and oils.

What concentration is cetearyl alcohol typically present in skin care formulas?

In the majority of skin care formulas, cetearyl alcohol is present in under a 5% concentration, although higher amounts are permissible.

Is cetearyl alcohol considered safe for use in cosmetic products?

Yes, the Cosmetic Ingredient Review (CIR) Expert Panel has concluded that fatty alcohols, including cetearyl alcohol, are safe for use in cosmetic products.

What effect does cetearyl alcohol have on the skin?

Cetearyl alcohol traps water and provides a soothing feel to the skin, making it an effective emollient.

Has cetearyl alcohol shown any significant toxicity or mutagenic properties in clinical studies?

No, clinical studies have found that cetearyl alcohol has no significant toxicity and is non-mutagenic.

Case Study

Preparation of Cetearyl Alcohol Surfactant Gel Material

Colafemmina, Giuseppe, et al. Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2020, 597, 124821.

The ternary system, surfactant/fatty alcohol/water, can form a layered structure, forming a permeable network and thus producing a gel. A ternary system gel material of cetearyl alcohol/cetyltrimethylammonium chloride (CTAC)/water mixture was prepared, and the effects of different cooling processes on the structure and properties of the gel material were explored. The results show that the periodic repeating distances of fast and slow cooling are 31.4 and 28.5 nm, respectively, which means that the volume fraction of the fast cooling sample is lower.
Preparation of cetearyl alcohol/CTAC/water ternary gel
· The cetearyl alcohol (CA) concentration was kept constant at 5 wt.%, with 6 wt.% of cetyltrimethylammonium chloride (CTAC) in 89 wt.% of heavy water.
· Samples were prepared by first keeping samples at 85 °C in a water bath for 15 minutes under stirring.
· In the first process after heating, the samples were rapidly cooled down straight after preparation by putting them in a water bath with ice for one hour.
· For the second process, the samples were allowed to cool down quiescently at room temperature without stirring, at an estimated cooling rate of 5 °C/min.
