Ethyl Butylacetylaminopropionate

Ethyl butylacetylaminopropionate (also known as IR3535) is a synthetic organic compound primarily recognised for its role as a mosquito repellent. In skincare formulations, it functions as a skin conditioner and surfactant—ingredients that help improve skin feel and texture by enhancing the spreadability and sensory properties of products.The ingredient has a documented history of use in protective formulations, particularly in ointments designed for water-based activities. Its inclusion in skincare is typically functional rather than therapeutic, supporting the overall performance and appl…

Ethyl butylacetylaminopropionate works primarily as a conditioning agent by interacting with the skin's surface to create a smoother feel and improve how products glide across the skin. As a surfactant, it helps to reduce surface tension, allowing formulations to spread more evenly and absorb more effectively.The ingredient's molecular structure allows it to film-form on the skin, which can contribute to a polished appearance and help maintain product consistency during storage and application.

Ethyl butylacetylaminopropionate is typically a minor ingredient in formulations, so there are no specific usage guidelines required. Use the product as directed by the manufacturer. Its benefits are delivered through the overall formulation rather than through targeted application techniques.

Ethyl butylacetylaminopropionate is generally well-tolerated in cosmetic products. As with any ingredient, individuals with known sensitivities should check the full ingredient list before use.
