About this ingredient

Dibutyl Adipate is a clear, colorless ester of adipic acid and n-butanol. In cosmetics it works as an emollient and a solvent for oil-soluble UV filters. The molecule has a light, dry skin feel similar to silicone fluids but is fully metabolizable by mammalian lipases. The most important role of Dibutyl Adipate is dispersing modern UV filters in sunscreens. Filters such as bemotrizinol, bisoctrizole, ethylhexyl triazone, and avobenzone all need a high-quality lipid carrier to stay homogeneous in the formula and reach the skin evenly. Dibutyl Adipate dissolves these filters at concentrations up to 30% and helps the finished sunscreen apply without greasy residue. Beyond sunscreens, the ester appears in body lotions, lightweight moisturizers, and color cosmetics where a non-occlusive emollient is needed. Typical use concentration is 1-15%. Pregnancy safety. Dibutyl Adipate is considered safe during pregnancy at cosmetic concentrations. Skin penetration is limited, and the molecule is metabolized to adipic acid and butanol, both of which are endogenous or food-grade compounds. There are no documented teratogenic effects. Skin safety. Low irritation, low allergen risk, and not comedogenic in finished products. Suits all skin types including sensitive and acne-prone skin. Regulatory status. Approved by the FDA, EU Cosmetic Regulation, and Japanese cosmetic standards. CIR reviewed dialkyl adipates as a class with a safe verdict. Bottom line. Dibutyl Adipate is a high-performing emollient ester used in modern photostable sunscreens. Pregnancy-safe, low-irritation, low-allergen, non-comedogenic, and one of the workhorse solvents behind smooth Asian and European sun-care formulas.
