Nonaethylene Glycol Monododecyl Ether

Nonaethylene Glycol Monododecyl Ether (CAS 3055-99-0 ), commercially known as Laureth-9 , is a nonionic ethoxylated fatty alcohol surfactant used across personal care and pharmaceutical manufacturing. It functions as an emulsifier, solubilizer, and carrier, enabling the stable incorporation of oils, actives, and poorly water-soluble ingredients into aqueous systems for various industrial applications. In personal care formulations, Laureth-9 solubilizes fragrance oils and lipophilic actives into clear aqueous bases such as micellar waters, toners, and light serums to ensure product clarity. Pharmaceutical manufacturers use it as a solubilizing agent and permeation enhancer in topical and semi-solid dosage forms, improving the delivery of active ingredients through formulation matrices. In cosmetic emulsions and cleansing products, it contributes to stable oil-in-water systems while supporting foam texture and rinse-off performance for high-quality consumer goods. It also functions as a wetting agent in spermicidal and contraceptive gel formulations, where its surfactant activity is the basis for efficacy in specialized medical applications. Laureth-9 is supplied as a liquid or low-melting paste depending on temperature and concentration. It is available in cosmetic-grade and pharmaceutical-grade specifications for global supply. The latter is subject to compendial standards relevant to topical and semi-solid applications. Bulk supply is standard in drums and IBCs to meet the needs of large-scale manufacturing facilities.
