SODIUM LANETH SULFATE.

Valuable CAS 68919-23-3 / CLEANSING, EMULSION STABILISING, SKIN CONDITIONING, SURFACTANT - CLEANSING

Sodium Laneth Sulfate is a versatile surfactant primarily employed for its cleansing, emulsifying, and foaming capabilities in various skincare and personal care formulations. It effectively aids in the removal of oil and dirt from the skin, while also contributing skin conditioning benefits.

Cleansing Agent Emulsifying Agent Foaming Agent Skin Conditioning Agent

Science

Mechanism of Action

As a primary surfactant, Sodium Laneth Sulfate works by reducing the surface tension between immiscible liquids, such as water and oils. This action enables the efficient mixing and subsequent rinsing away of dirt, sebum, and makeup. Its surfactant properties also facilitate emulsion formation and generate foam, while it is additionally reported to act as a skin conditioning agent.

Stability

While specific pH stability parameters for Sodium Laneth Sulfate are not explicitly detailed, related sulfate surfactants like Sodium Lauryl Sulfate (SLS) typically demonstrate stability within a pH range of 7.0 to 9.5 in a 1% aqueous solution. Formulators should be mindful that alkaline cleansing formulations may disrupt the skin barrier. To minimize potential irritation, it is common practice to integrate co-surfactants, such as amphoteric (e.g., cocoamidopropyl betaine) and non-ionic (e.g., coco or decyl glucoside) agents.

Synergies

  • Amphoteric co-surfactants (e.g., cocoamidopropyl betaine) to reduce irritation potential.
  • Non-ionic co-surfactants (e.g., coco or decyl glucoside) to reduce irritation potential.
