Caprylylglycol ●
TL;DR. This ingredient is primarily used as a humectant and preservative booster. It helps bind water while improving the performance of preservative systems, especially in emulsions and water-based formulas.
What does Caprylylglycol do in a cosmetic formula?
This ingredient is primarily used as a humectant and preservative booster. It helps bind water while improving the performance of preservative systems, especially in emulsions and water-based formulas.
Is Caprylylglycol clean?
Clean-beauty standards generally treat it as acceptable, with low sensitization concern at typical use levels. The main watchpoint is mild eye or skin irritation in higher amounts or in very sensitive formulas.
Is Caprylylglycol sustainable?
This material can be made from petrochemical or plant-derived feedstocks, so sourcing depends on the supplier. It is generally expected to biodegrade and is not known as a persistent silicone-like or fluorinated material.
Is Caprylylglycol COSMOS-approved?
COSMOS alignment is grade-dependent, with naturally derived versions more likely to fit COSMOS-natural frameworks and petrochemical versions less aligned. From a Green Chemistry view, renewable sourcing and straightforward biodegradation improve its profile, while synthetic route transparency matters.
How does Caprylylglycol work chemically?
The molecule is an eight-carbon amphiphilic diol, which lets it sit at water-oil interfaces and disrupt microbial membrane function enough to support preservatives. Typical use is often around 0.3% to 1%, and it is broadly stable across common cosmetic pH ranges.
