Diisopropyl Adipate, a diester derived from the combination of isopropyl alcohol and adipic acid, serves as a versatile ingredient in various cosmetic applications. It is characterized by its clear, colorless, and odorless properties and functions as a lightweight, non-occlusive, and non-oily emollient. Its low viscosity facilitates rapid spreading and absorption when applied to the skin, leaving minimal residue. While it is insoluble in water, ethylene glycol, and glycerol, it dissolves readily in alcohols, glycols, ketones, esters, and various solvents and oils. This solubility profile makes it especially valuable in hydro-alcoholic formulations such as creams, lotions, bath oils, lip balms, and antiperspirants. Additionally, it offers excellent compatibility with other personal care ingredients, serving also as a coupling agent and solubilizer for lipophilic systems. In skincare formulations, Diisopropyl Adipate enhances lubrication and provides a mildly drying, soft after-feel, making it a preferred choice in bath oils, lipsticks, and decorative cosmetics combined with butters, natural and mineral oils, and esters.
