Residual Solvent Testing in Cosmetics

Solvents can be added to cosmetics to help dissolve ingredients used in cosmetic products. Water is the most common solvent and the phase used constantly in most suspensions and water/oil emulsions. Solvents used in cosmetics include acetone, denatured alcohol, butoxyethanol (ethylene glycol monobutyl ether), diethylene glycol, dimethyl isosorbide, ethyl acetate, heptane, isopropyl alcohol, mineral alcohol, polyethylene glycol, propylene glycol, toluene and tricaprine (glyceryl tri-n-) is found. decanoate). The choice of solvent for use in cosmetics is a complex task due to topical and inhalation toxicity as well as odor.

One ​​of the tests performed on cosmetic products is the Solvent Residue Test. The purpose of the Solvent Residue Test is to determine whether the end product contains solvents at unsafe levels that may be harmful to the environment or humans, and that may endanger the quality and/or functionality of the product. The Residue Test can determine the presence of residual solvents or other impurities and whether they are present in harmful amounts.
