Science
Mechanism of Action
This ingredient operates primarily as an emulsifier, creating stable, homogeneous mixtures in formulations by effectively dispersing oil within water, preventing separation. As a cleansing agent, it facilitates the removal of oily dirt particles from the skin, which helps mitigate concerns like acne and body odor. Furthermore, the inherent rapeseed sterols bolster the skin's lipid barrier, reducing transepidermal water loss, maintaining suppleness, and offering protection against environmental aggressors. It may also augment the absorption of other beneficial active compounds into the skin.

Stability
As an effective emulsifier, PEG-10 Rapeseed Sterol is crucial for stabilizing oil and water emulsions, preventing product separation. Its optimal stability is observed within a pH range of 4.5 to 7.0, based on aqueous dispersions.
Conflicts
- Not advised for application on compromised or damaged skin, given reported instances of systemic toxicity and sensitization linked to PEGs in burn patients.
- May heighten skin irritation when formulated alongside other known problematic ingredients.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed PEG-10 Soy Sterol, a closely related or synonymous ingredient, safe for use in cosmetic products. Its maximum reported usage concentration is 2.6% in rinse-off products and 2.1% in leave-on formulations. However, a significant cautionary note advises against its use on damaged skin due to potential systemic toxicity and sensitization risks observed in individuals with burns when exposed to PEGs. For intact skin, the risk of sensitization is considered low.
