LANETH-4 PHOSPHATE.

Avoid / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

LANETH-4 PHOSPHATE is a versatile ingredient that stabilizes oil-in-water emulsions and functions as a gentle cleansing and conditioning agent. It supports consistent product texture and can enhance the absorption of other active compounds in skincare formulations.

Summary

Emulsifying Cleansing Surfactant Skin Conditioning Absorption Enhancer

Science

Mechanism of Action

This ingredient primarily acts as an emulsifier, stabilizing mixtures of oil and water to ensure uniform distribution of active ingredients and a consistent product texture. It also functions as a surfactant and cleansing agent, effectively removing dirt and impurities from the skin. Furthermore, LANETH-4 PHOSPHATE contributes to maintaining skin moisture, softness, and elasticity, and can improve the epidermal absorption of other beneficial ingredients.

Stability

LANETH-4 PHOSPHATE is dispersible in water and soluble in various oils (paraffin, naphthenic, rape-seed) and organic solvents (methanol, acetone, benzene). It demonstrates emulsifying, solubilizing, and dispersing capabilities across a wide pH range, contributing to formula stability against temperature fluctuations and being suitable for cold-processable formulations without requiring specific pH adjustments.

Caution
Sensitization risk Unknown

The CIR Expert Panel concluded that alkyl phosphates, including LANETH-4 PHOSPHATE (often referred to as Laureth-4 Phosphate), are safe for use in cosmetics when formulated to be non-irritating. However, the California OEHHA Proposition 65 List (2020 Update) identifies Laureth-4 Phosphate as 'Known to cause reproductive toxicity (to females)' and 'Known to cause reproductive toxicity (to males)'. This ingredient is also listed by the FDA as an indirect food additive under 21 CFR 178.3400.

Verdict

Avoid

Despite its beneficial emulsifying and skin conditioning properties, the ingredient's classification under California Proposition 65 for reproductive toxicity necessitates its avoidance in precision skincare formulations.
