Alcohol Denat ●
TL;DR. It is primarily a fast-evaporating solvent and carrier, helping dissolve fragrance, actives, and film-formers while giving formulas quick dry-down and a lighter feel. It can also support preservation by lowering water activity and helping preservative systems perform.
What does Alcohol Denat do in a cosmetic formula?
It is primarily a fast-evaporating solvent and carrier, helping dissolve fragrance, actives, and film-formers while giving formulas quick dry-down and a lighter feel. It can also support preservation by lowering water activity and helping preservative systems perform.
Is Alcohol Denat clean?
Clean frameworks generally permit it, but it draws scrutiny because it can sting or dry skin at higher placement in leave-on formulas, especially for sensitive or impaired barriers. The added agents used to make it non-drinkable can also affect acceptance depending on the standard.
Is Alcohol Denat sustainable?
This material can be made from fermented plant sugars or fossil feedstocks, so sourcing matters. It is readily biodegradable and not persistent, but it is a VOC, and crop-based supply can carry land, water, and farming-input considerations.
Is Alcohol Denat COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when the base material and added agents meet standard requirements, and organic grades can count toward organic content when sourced accordingly. From a Green Chemistry lens, the best fit is renewable fermentation, ready biodegradation, and simple distillation, with weaker alignment when fossil-derived or paired with less-preferred added agents.
How does Alcohol Denat work chemically?
The molecule is a small, polar, two-carbon solvent with water compatibility and enough lipophilic character to dissolve many aroma compounds and some actives. It is typically used from a few percent in toners and serums to 20 to 70% in sprays, gels, and hand-rub formats, evaporates quickly, and can destabilize some emulsions at high levels.
