ALCOHOL DENAT. SD ALCOHOL 31-A
Description
Alcohol Denat. SD Alcohol 31-A is a widely used ingredient in skincare and haircare formulations. This denatured alcohol is derived from ethanol and contains denaturants to render it unfit for consumption. Its primary function is as a solvent and quick-drying agent, making it particularly useful in products that require rapid evaporation, such as hair sprays and skin toners.
In skincare, Alcohol Denat. SD Alcohol 31-A acts as an astringent, temporarily tightening pores and providing a cooling sensation upon application. It enhances the penetration of other active ingredients and can help control excess oil production. However, its drying properties may be problematic for sensitive or dry skin types when used in high concentrations.
In haircare, this ingredient assists in the even distribution of products and quick setting of hairstyles. It's particularly effective in aerosol sprays, where it helps to disperse active ingredients and propellants. While it can provide temporary hold and volume, excessive use may lead to dryness and brittleness of hair.
Formulators must balance the benefits of Alcohol Denat. SD Alcohol 31-A with potential drawbacks, considering skin and hair types when determining appropriate concentrations in products.
