PEG-30 HYDROGENATED LANOLIN.

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

PEG-30 Hydrogenated Lanolin is a versatile polyethylene glycol derivative known for its skin conditioning and emollient properties. It effectively functions as an auxiliary emulsifier in formulations and contributes to skin hydration by retaining moisture.

Science

Mechanism of Action

This ingredient acts as a skin conditioning agent, emollient, and a surfactant, specifically as an auxiliary oil/water emulsifier. It promotes stable emulsions by reducing the surface tension of components. On the skin, it provides a lubricating effect, resulting in a soft and smooth tactile feel. As a humectant, it leverages its polyethylene glycol structure to form hydrogen bonds with water molecules, thereby drawing and locking moisture into the skin. This action supports superior hydration, diminishes transepidermal water loss, and aids in restoring the skin's natural barrier function.

Key findings

  1. 01 A CIR Safety Review indicated that PEG-30 Hydrogenated Lanolin caused mild or negligible skin irritation and was nonsensitizing in animal studies at concentrations ranging from 10% to 100%.
  2. 02 Further patient studies reported that concentrations between 10% and 60% were found to be nonirritating and nonsensitizing.

Stability

A 5% aqueous solution maintains stability within a pH range of 3.5 to 8.0. It is completely soluble in water, though concentrated solutions might exhibit slight opalescence at room temperature, which is reversible upon cooling. Prolonged heating above 80 °C should be avoided to preserve stability.

Synergies

  • Cetyl Alcohol (enhances foam and emulsion stability)
  • Cetostearyl Alcohol (enhances foam and emulsion stability)

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The CIR Expert Panel has concluded that PEG-30 Hydrogenated Lanolin is safe for use in cosmetic and personal care products. It has demonstrated non-toxicity in acute oral, dermal, and inhalation studies across various concentrations, and caused little to no eye irritation at concentrations of 50-100%. While trace amounts of 1,4-dioxane, a byproduct of ethoxylation, may be present, its levels are controlled through stringent purification processes, a fact acknowledged by the FDA.
