PEG-70 HYDROGENATED LANOLIN.

Valuable CAS 68648-27-1 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

PEG-70 Hydrogenated Lanolin is a polyoxyethylene derivative of hydrogenated lanolin, primarily valued in formulations for its emollient and surfactant properties. It significantly enhances skin hydration and barrier function, providing a smooth feel and improving product texture across diverse cosmetic applications. Its high ethoxylation count (70) indicates robust water solubility and emulsifying capabilities.

Science

Mechanism of Action

This ingredient acts as an effective emollient, delivering profound skin conditioning and reducing transepidermal water loss to enhance suppleness. As a surfactant, it lowers surface tension, facilitating emulsion formation and stability. It also functions as a lubricant, bestowing a soft and smooth appearance to the skin while mitigating the defatting effects of cleansing agents, thereby strengthening the skin's protective barrier.

Stability

This nonionic ingredient demonstrates excellent stability across a broad pH range of 2 to 10, inferred from related PEG Lanolins like PEG-75 Lanolin. It is generally compatible with a wide array of other solubilizers, including solutions containing up to 10% electrolytes. Minor effects may be observed when exposed to strong oxidative or reducing agents.

Synergies

  • Enhances compatibility with various solubilizers and tolerates up to 10% electrolyte concentrations, making it versatile in complex formulations.

Conflicts

  • May be slightly affected by strong oxidative or reducing agents.

Safety

Safety Profile

CIR Status
Safe as used
Max tested
100%
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has determined that PEG-70 Hydrogenated Lanolin is safe for use in cosmetics, consistent with other PEG Lanolins. Studies supporting this conclusion included concentrations up to 100%, demonstrating minimal or negligible skin irritation and non-sensitizing effects in both animal and human trials (up to 60% in humans). As a polyethoxylated compound, there is a potential for trace amounts of 1,4-dioxane; however, manufacturers typically employ purification processes to control levels within safe limits, a practice supported by the FDA. No specific SCCS status was found, but it conforms to EU cosmetic regulations.
