AQUABUTYLENE GLYCOL ●
TL;DR. It serves mainly as a solvent, humectant, and carrier, helping dissolve actives, preservatives, and botanical extractives while improving the feel of gels, serums, creams, and cleansers.
What does AQUABUTYLENE GLYCOL do in a cosmetic formula?
It serves mainly as a solvent, humectant, and carrier, helping dissolve actives, preservatives, and botanical extractives while improving the feel of gels, serums, creams, and cleansers.
Is AQUABUTYLENE GLYCOL clean?
Clean standards usually treat it as acceptable when impurity control is good, since it has a low sensitization history and is widely used in leave-on products. The main friction is synthetic origin in stricter natural frameworks rather than a major skin-safety issue.
Is AQUABUTYLENE GLYCOL sustainable?
Commercial supply can be petrochemical or fermentation-based, so sourcing documentation matters. It is readily biodegradable and not known for environmental persistence, with a better Green Chemistry profile when made from renewable feedstocks.
Is AQUABUTYLENE GLYCOL COSMOS-approved?
Conventional synthetic grades are generally not aligned with COSMOS-natural or COSMOS-organic formulas, while bio-based grades may be acceptable when made through approved processing and properly documented. It fits Green Chemistry better when fermentation-derived, readily biodegradable, and used as a low-volatility solvent.
How does AQUABUTYLENE GLYCOL work chemically?
This small diol has two hydroxyl groups, which gives it strong solvent and humectant behavior plus good compatibility in aqueous gels, emulsions, and leave-on serums. Typical use is about 1 to 10%, often 2 to 5%, and it is stable across normal cosmetic pH ranges while helping solubilize some preservatives, aromatic materials, and extractives.
