C12-15 Pareth-7

What is C12-15 Pareth-7?

C12-15 Pareth-7 is a synthetic non-ionic surfactant made by reacting a blend of C12 to C15 linear alcohols with seven molecules of ethylene oxide. This ethoxylation process yields a versatile ingredient with balanced hydrophilic and lipophilic segments, classifying it within the pareth series used widely in personal care products. It appears in categories such as shampoos, shower gels, facial washes, and emulsion-based moisturizers. Its core function involves lowering interfacial tension between oil and water, facilitating the removal of sebum, residues, and impurities during rinsing. As an emulsifier, it forms protective films around oil droplets, promoting phase stability and smooth application in lotions and creams. This dual role supports clear, homogeneous textures without compromising mildness, aligning with formulations for broad consumer use. Assessments from cosmetic safety panels confirm its suitability at common levels.
