Science

Mechanism of Action

SHEA BUTTER PEG-32 ESTERS acts as a sophisticated delivery system, combining the natural nourishing components of shea butter, such as unsaturated fatty acids, Vitamin E, and allantoin, with the versatile properties of a PEG. On the skin, it functions as an effective emollient, forming a protective barrier that locks in moisture, thereby enhancing skin softness, elasticity, and overall hydration. In formulations, its amphiphilic structure allows it to perform as an emulsifier, surfactant, and solubilizer, seamlessly blending typically immiscible oil and water components to create stable and homogeneous products.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The CIR Expert Panel generally considers PEGs, including similar compounds like PEG-32 distearate, 'safe as used.' However, a crucial caveat exists for use on compromised or damaged skin, where increased absorption could potentially lead to contact dermatitis or systemic toxicity. While generally regarded as non-irritating, there is a recognized risk of trace contamination by ethylene oxide or 1,4-dioxane, byproducts of the ethoxylation process. EWG categorizes this ingredient as 'RESTRICTED,' citing broader concerns regarding PEGs' potential for carcinogenicity or reproductive toxicity, though specific data for SHEA BUTTER PEG-32 ESTERS on these particular risks is not available.
