Heptyl glucoside is a natural alkyl glycoside and hydrotrope that aids in dispersing pigments in decorative cosmetics, inorganic compounds in sunscreens, and antiperspirant agents in deodorants. It also improves the clarity of gels in solutions with high electrolyte content. This substance increases the solubility of active pharmaceutical ingredients, thus improving skin permeability and reducing the necessary dosage of APIs in transdermal pharmaceutical compositions. In skincare, it’s a natural and sustainable solubilizer.
