Cetearyl Nonanoate ●
TL;DR. This ingredient is an emollient ester that gives creams, lotions, and hair products a soft, dry, cushiony feel. It helps spreadability and reduces the greasy finish of heavier oils and waxes.
What does Cetearyl Nonanoate do in a cosmetic formula?
This ingredient is an emollient ester that gives creams, lotions, and hair products a soft, dry, cushiony feel. It helps spreadability and reduces the greasy finish of heavier oils and waxes.
Is Cetearyl Nonanoate clean?
From a clean-beauty perspective, it is generally well tolerated and not a common restricted-list ingredient. The main watchpoint is sourcing and processing transparency, rather than irritation or sensitization.
Is Cetearyl Nonanoate sustainable?
This material can be made from fatty alcohol and fatty acid feedstocks that may be plant-derived or petrochemical-derived. It is expected to biodegrade more readily than silicone emollients, but palm-linked fatty alcohol sourcing can be a supply-chain consideration.
Is Cetearyl Nonanoate COSMOS-approved?
It can fit COSMOS-natural standards when made from approved renewable feedstocks through allowed esterification chemistry. It is less aligned when petrochemical feedstocks are used, so DARE treats it as conditionally aligned rather than automatically green.
How does Cetearyl Nonanoate work chemically?
The molecule is a long-chain fatty ester, which explains its low polarity, slip, and skin-conditioning feel. It is typically stable across the normal pH range of emulsions, but like other esters, it can slowly hydrolyze under strongly acidic or alkaline conditions.
