Sodium dodecylphosphate

Sodium dodecylphosphate (CAS 50957-96-5), also known as Sodium lauryl phosphate, is an anionic surfactant derived from lauryl alcohol and phosphoric acid. It delivers effective surface-active performance across personal care and industrial formulations.

This chemical is highly valued where mildness and emulsification are priorities. In personal care, it functions as a cleansing and emulsifying agent in shampoos, facial cleansers, and body washes for consumers.

It offers a milder profile than conventional sulfate-based surfactants. Household and industrial cleaning formulations use it to degrease hard surfaces and stabilize emulsified soil suspensions in liquid detergent systems.

Textile processing operations employ it as a scouring and wetting agent to remove oils and sizing agents from fiber substrates before dyeing. This ensures a high-quality finish for various fabric types.

In leather and paper processing, it supports emulsification of treatment baths and improves penetration of finishing agents into substrate surfaces. This versatility makes it a staple in heavy industrial manufacturing.

Sodium dodecylphosphate is typically supplied as a liquid or paste, with concentration levels varying by grade and intended application. Both cosmetic-grade and technical-grade material are available in the market.

Cosmetic grades meet specific purity requirements for personal care use. Bulk supply is standard in drums or IBC containers, with smaller packaging available for laboratory and formulation development use.
