CETEARYL ETHYLHEXANOATE

CAS Number 90411-68-0
Chem/IUPAC Name: Hexanoic acid, 2-ethyl-, C16-18-alkyl esters
EINECS/ELINCS No: 291-445-1
COSING REF No: 75136
CETEARYL ETHYLHEXANOATE
Cetearyl ethylhexanoate is the ester of cetearyl alcohol and 2-ethylhexanoic acid and was formerly called cetearyl octanoate. It is a transparent, oil-like, water-resistant liquid that protects skin from moisture loss by acting as an emollient. Cetyl ethylhexanoate, which has a comparable chemical makeup but slightly different properties and safety, should not be confused with this ingredient.

What is CETEARYL ETHYLHEXANOATE used for?

Cetearyl ethylhexanoate works as an emoliient, texture enhancer and a conditioning agent in cosmetics and personal care products.
  • Skin care: It smooths and softens the skin. It adds a sophisticated spreadability to creams and lotions and is oxygen-stable in addition to its moisturizing qualities. In leave-on products, cetearyl ethylhexanoate can be used up to 35% of the time. Additionally, it serves as a replacement for whale-derived spermaceti wax. Numerous cosmetic products, including foundation, facial moisturizers, lipsticks, lip glosses, lip/eye liners, conditioners, and anti-aging products, contain cetearyl ethylhexanoate

Origin

Commercially, cetearyl ethylhexanoate is produced through the catalytic esterification of cetearyl alcohol and 2-ethylhexanoic acid, with the removal step being an azeotropic distillation. Cetyl octanoate and stearyl octanoate can also be combined in a 7:2 weight ratio to create the product.

Safety profile

The safety of 16 alkyl ethylhexanoates, including cetearyl ethylhexanoate, as used in cosmetics was evaluated by the Cosmetic Ingredient Review (CIR) Expert Panel. The panel looked over any clinical data on these ingredients that was available. The panel came to the conclusion that these ingredients are safe when used in cosmetic formulations under the current usage and concentration patterns when they are made to be non-irritating.
