Butyloctyl Salicylate is a synthetic ester commonly used in sunscreens to solubilize UV filters and enhance product performance. It has a pleasant, silky finish and acts as a solvent in personal care products to improve the spreadability and texture of formulations. It also moisturizes the skin and conditions hair. Butyloctyl Salicylate is popular as a “functional ingredient” as it doesn’t just sit on the surface but helps other actives work better. Apart from sunscreens, it is commonly found in BB and CC creams, tinted moisturizers, foundations with sun protection, anti-aging serums, and body lotions with UV filters. However, Butyloctyl Salicylate is avoided by clean beauty brands due to potential side effects and risks for the environment.

What is BUTYLOCTYL SALICYLATE used for?
- Solvent - Butyloctyl Salicylate dissolves and stabilizes actives, UV filters, and other hydrophobic ingredients within a formulation. This improves product performance and stability. Additionally, its rich, silky texture allows products to achieve a smooth finish and enhances spreadability.
- Emollient - Butyloctyl Salicylate has a lightweight, velvety feel that improves the sensory profile of cosmetics. It forms a breathable layer on the skin that reduces moisture loss without feeling heavy or greasy.
- Conditioning - Butyloctyl Salicylate acts as a conditioning agent in hair care products - smoothening the shafts out and improving manageability. The ingredient provides both immediate sensory feel and long-term conditioning benefits, making products more nourishing.
Origin
Butyloctyl Salicylate is made by the esterification of salicylic acid and butyloctyl alcohol. The reaction takes place in the presence of a catalyst and under controlled heat. The water generated during the process is removed continuously to drive the reaction towards completion. Once Butyloctyl Salicylate is made, it is neutralized, washed, and purified for use in cosmetics. Butyloctyl Salicylate appears as a clear to slightly yellow liquid in its raw form, and its chemical formula is C19H30O3.

UV FILTERSafety Profile
Butyloctyl Salicylate is safe for cosmetics when used within the recommended concentration of less than 5%. Higher concentrations may cause irritation and sensitivity. Since it is derived from salicylic acid, an exfoliant, it may cause redness, itching, and breakouts with repeated use. Butyloctyl Salicylate should be avoided by children and individuals with sensitive, acne-prone, or compromised skin. Additionally, Butyloctyl Salicylate causes environmental degradation as it is not biodegradable and may accumulate in water systems.
