CAPYLYL GLYCOL ●
TL;DR. This ingredient is primarily a humectant and preservative booster, helping bind water while improving the performance of antimicrobial systems. It also adds light skin-conditioning and can support formula feel in emulsions, gels, and anhydrous blends.
What does CAPYLYL GLYCOL do in a cosmetic formula?
This ingredient is primarily a humectant and preservative booster, helping bind water while improving the performance of antimicrobial systems. It also adds light skin-conditioning and can support formula feel in emulsions, gels, and anhydrous blends.
Is CAPYLYL GLYCOL clean?
From a clean-beauty perspective, it is generally well tolerated and not a major restricted-list concern. Mild eye or skin irritation can occur at higher use levels, so it is usually kept at low percentages in leave-on formulas.
Is CAPYLYL GLYCOL sustainable?
This material can be made from plant-derived fatty acids or petroleum-derived feedstocks, so sourcing matters. It is expected to be readily biodegradable and does not carry the persistence concerns associated with many silicone or fluorinated materials.
Is CAPYLYL GLYCOL COSMOS-approved?
It can align with COSMOS-natural when it is derived from approved renewable feedstocks and made through accepted processing routes, but petroleum-derived versions would not qualify the same way. From a Green Chemistry view, its profile is strongest when bio-based, efficiently processed, and used at low levels to support preservation.
How does CAPYLYL GLYCOL work chemically?
The molecule is a small eight-carbon vicinal diol, giving it both water-compatible hydroxyl groups and enough lipophilicity to interact with microbial membranes and oil phases. Typical use is about 0.3% to 1.0%, and it is broadly pH-stable and often paired with chelators, organic acids, or other preservative boosters for broader protection.
