Where is Sodium methyl oleoyl taurate used?

• Textile wet processing: scouring and wetting agent that removes oils, waxes and sizing agents from fiber surfaces before dyeing or finishing
• Personal care: foaming agent, emulsifier and detergent active in mild shampoos, body washes and facial cleansers
• Leather processing: supports degreasing and fat-liquoring for uniform penetration of treatment chemicals
• Paper manufacturing: dispersing and wetting agent that improves fiber distribution and surface uniformity during sheet formation
• It provides a creamy lather without causing irritation.

Good to know: Buyers should confirm active content and sodium chloride levels when evaluating grades for sensitive formulations such as personal care products. Store in a cool, dry environment to maintain paste stability.
