PEG-12 ALLYL ETHER.

Valuable CAS 27274-31-3 / BINDING

PEG-12 ALLYL ETHER is a versatile synthetic polymer that primarily functions as a binding agent, humectant, and solvent in cosmetic formulations. It enhances ingredient cohesion and aids in uniform distribution, while also attracting moisture to the skin to support hydration.

Science

Mechanism of Action

As a member of the polyethylene glycol (PEG) family, PEG-12 ALLYL ETHER is highly hydrophilic, enabling it to draw water to the skin's surface, thereby functioning as an effective humectant. It also acts as a solvent, facilitating the dissolution and even dispersion of other ingredients within a formulation, and can substitute for glycerol in certain applications. Beyond its role in improving product texture and stability as a binding agent, it may also enhance the penetration of other active ingredients into the skin, particularly in topical dermatological preparations.

Stability

Polyethylene glycols, including PEG-12 ALLYL ETHER, generally exhibit strong microbiological stability, often negating the necessity for additional preservatives in their presence.

Safety

Safety Profile

CIR Status
Safe as used with restrictions
Sensitization risk Low

The CIR Expert Panel considers Alkyl PEG Ethers, including PEG-12 ALLYL ETHER, safe for cosmetic use when formulated to be non-irritating. It is advised to avoid use on compromised or damaged skin, as PEGs may increase penetration and potentially cause irritation. While no specific maximum concentration is set for PEG-12 ALLYL ETHER, analogous ingredients are typically used below 5% in leave-on products and up to 10% in rinse-off applications. Manufacturers must ensure the removal of impurities like ethylene oxide and 1,4-dioxane. This ingredient is synthetic and petroleum-derived, which may be a consideration for natural or organic certifications. Environmental concerns exist due to its limited biodegradability.
