Science
Mechanism of Action
This ingredient operates as an emollient by forming a partially occlusive film on the skin's surface, which effectively reduces transepidermal water loss (TEWL) and facilitates the rehydration and softening of dry skin. Its polyethylene glycol (PEG) component contributes solubilizing capabilities, enhancing the spreadability and absorption of other active ingredients. Additionally, it serves as an excellent emulsifier, promoting stable and uniform blends within cosmetic preparations.

Stability
As an alkoxylated, water-soluble lanolin derivative, PPG-12-PEG-65 Lanolin Oil is an excellent emulsifier, enhancing emulsion stability, and also functions as a solubilizer and plasticizer. Its water solubility integrates well into aqueous cosmetic formulations. Formulators must ensure the use of purified grades to mitigate potential contamination from residual 1,4-dioxane and ethylene oxide, byproducts of the ethoxylation process.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that polyether lanolins, including PPG-12-PEG-65 Lanolin Oil, are safe for use in cosmetic products. The maximum reported concentrations are 0.1% in leave-on products and 0.4% in rinse-off products, primarily observed in hair care applications. It is crucial to use purified grades of this ingredient to avoid potential toxic impurities such as ethylene oxide and 1,4-dioxane, which can arise from the ethoxylation process. The CIR generally advises against using cosmetic formulations containing PEGs on compromised or damaged skin.
