SODIUM LAUROAMPHO PG-ACETATE PHOSPHATE.

Valuable CAS 193888-44-7 / CLEANSING, FOAMING, HAIR CONDITIONING, SURFACTANT - CLEANSING, SURFACTANT - FOAM BOOSTING, SURFACTANT - HYDROTROPE

Sodium Lauroampho PG-Acetate Phosphate is a sophisticated amphoteric surfactant designed for gentle yet thorough cleansing of both skin and hair. This ingredient effectively lifts impurities while significantly boosting foam production and overall product mildness. Its unique ability to reduce irritation from co-surfactants makes it a versatile choice for a wide range of formulations.

Cleansing Lather Agent Foam Booster Hair Conditioning Agent Hydrotrope Anti-blemish

Science

Mechanism of Action

As an amphoteric surfactant, SODIUM LAUROAMPHO PG-ACETATE PHOSPHATE functions by enabling water, oil, and dirt particles to mix, facilitating their efficient removal from the skin and hair. Beyond its primary cleansing action, it enhances lather and boosts foam, contributing to a luxurious product experience. This ingredient possesses the distinctive property of reducing irritation often caused by other co-surfactants, thereby improving formulation mildness. Additionally, it acts as a hair conditioning agent, promoting improved hair appearance and feel, and serves as a hydrotrope, enhancing the aqueous solubility of other beneficial substances.

Key findings

  1. 01 A Human Repeat Insult Patch Test (HRIPT) on Sodium Lauroamphoacetate, a closely related amphoacetate, demonstrated non-irritating and non-sensitizing properties in an aqueous solution at 0.5% (0.15% solids). Typical usage as a primary or secondary cleansing agent for amphoacetates falls within the 1-30% range.

Stability

The related ingredient, Sodium Lauroamphoacetate, is generally stable across a broad pH range and is biodegradable, although specific optimal pH ranges reported in literature are conflicting (e.g., 5.0-7.0 and 9.5-10.5). Formulations containing phosphate components may exhibit pH drift under frozen conditions, potentially due to precipitation.

Synergies

  • Increases foam, mildness, and viscosity in anionic/amphoteric formulations.
  • Reduces irritation caused by other co-surfactants.
  • Acts as a hydrotrope, enhancing the solubility of other substances in water.

Conflicts

  • Phosphate components may lead to pH drift and precipitation in frozen conditions.

Safety

Safety Profile

Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has deemed 'Amphoacetates', including the closely related Sodium Lauroamphoacetate, safe for use in cosmetics at current practices and concentrations. Separately, 'Phosphoric Acid and its salts' have also been reviewed by CIR and concluded safe when formulated to be non-irritating. This ingredient generally poses low concerns for issues such as cancer, allergies & immunotoxicity, developmental and reproductive toxicity, and use restrictions. While no specific SCCS or direct FDA cosmetic approval status for this exact ingredient was found, the FDA's Voluntary Cosmetic Registration Program (VCRP) does include usage data for Sodium Lauroamphoacetate.
