Sodium methyl oleoyl taurate

Sodium methyl oleoyl taurate (CAS 137-20-2), also known commercially as Hostapon T or Metaupon paste, is an anionic surfactant derived from oleic acid and taurine. It functions as a foaming agent, emulsifier, and detergent active across textile processing and personal care manufacturing. In textile wet processing, it acts as a scouring and wetting agent, helping to remove oils, waxes, and sizing agents from fiber surfaces before dyeing or finishing. This ensures a high-quality finish for various fabric types.

Personal care formulators incorporate it into mild shampoos, body washes, and facial cleansers where controlled foam and skin compatibility are formulation priorities. It is valued for its ability to provide a creamy lather without causing irritation. In leather processing, it supports degreasing and fat-liquoring operations, ensuring uniform penetration of subsequent treatment chemicals. This leads to a more consistent texture and color in the final leather products.

Paper manufacturing uses it as a dispersing and wetting agent to improve fiber distribution and surface uniformity during sheet formation. This application is critical for maintaining the structural integrity of the paper. Sodium methyl oleoyl taurate is commercially supplied as a paste, reflecting its typical physical form at ambient temperatures. It is available in technical grade, with active matter content commonly specified around 30–35%.

Buyers should confirm active content and sodium chloride levels when evaluating grades for sensitive formulations such as personal care products. Proper storage in a cool, dry environment is recommended to maintain the stability of the paste.
