PEG-15 BUTYLENE GLYCOL DIISOSTEARATE.

Insufficient Data / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

PEG-15 Butylene Glycol Diisostearate is a versatile cosmetic ingredient primarily functioning as a surfactant, emulsifier, and cleansing agent. It additionally aids in skin hydration by forming a moisture-retaining barrier and can facilitate the delivery of other active compounds.

Science

Mechanism of Action

Operating as a surfactant, cleansing agent, and emulsifier, PEG-15 Butylene Glycol Diisostearate contributes to formulation stability and cleansing efficacy. As a polyethelene glycol (PEG) derivative, it can also enhance skin hydration through hydrogen bonding with water molecules, thereby supporting the skin's barrier function and potentially reducing transepidermal water loss. Furthermore, it may act as a penetration enhancer for other topical ingredients.

Stability

PEGs can be susceptible to oxidation, potentially forming reactive hydroperoxides when exposed to oxygen, UV light, or metal traces. To maintain its integrity, it is advisable to store this ingredient in a dark, oxygen-protected environment, ideally with the inclusion of antioxidants and chelating agents. While specific pH stability data for this compound are not detailed, related PEG compounds generally exhibit robust stability across a broad pH spectrum.

Safety

Safety Profile

CIR Status
Insufficient data
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel has determined that the current data are insufficient to establish the safety of PEG-15 Butylene Glycol Diisostearate under its intended cosmetic uses. While PEGs are generally recognized for their low oral and dermal toxicity on intact skin, a critical concern arises for compromised skin: sensitization and nephrotoxicity have been reported in burn patients treated with PEG-containing formulations. Consequently, this ingredient should not be applied to damaged or severely compromised skin.
