C16-17 Alkyl Benzoate

C16-17 Alkyl Benzoate is a synthetic ester derived from benzoic acid and a mixture of C16-C17 fatty alcohols. It's a clear, colourless liquid commonly used in skincare formulations to improve texture, spreadability and sensory feel.In formulations, it functions as an emollient and skin conditioning agent, helping to soften the skin and enhance the overall aesthetic of a product. It also acts as a solvent, helping dissolve or suspend other active ingredients, and has mild antimicrobial properties that can support product stability.

C16-17 Alkyl Benzoate works primarily by forming a conditioning film on the skin's surface. This film helps to trap moisture and soften the stratum corneum (the outer layer of skin), contributing to a smoother appearance and improved comfort.Within the formulation itself, it acts as a solvent, helping to dissolve hydrophobic (water-repelling) ingredients so they can be evenly distributed throughout the product. This improves both efficacy and sensory experience during application.

C16-17 Alkyl Benzoate is typically used as part of a complete formulation rather than as a standalone ingredient. When using products containing this ingredient, apply as directed on the product label. It works well in lightweight serums, oils and moisturisers where smooth spreadability and non-greasy feel are desired. No special timing or frequency restrictions apply beyond the product's own instructions.

C16-17 Alkyl Benzoate is generally well-tolerated and recognised as safe for use in cosmetics by major regulatory bodies. It is unlikely to cause sensitivity in most skin types, though those with severe fragrance or ester sensitivities should patch-test first.
