PEI-14 PEG-24/PPG-16 COPOLYMER.

Insufficient Data CAS 52501-07-2 / ANTICAKING

PEI-14 PEG-24/PPG-16 Copolymer is a block copolymer primarily functioning as an anticaking agent to maintain the fluidity and prevent agglomeration of solid particles in formulations. It also offers versatile emulsifying, conditioning, and surfactant properties, making it valuable across various cosmetic applications.

Anticaking Emulsifying Conditioning Surfactant Solubilizer Solvent Consistency Enhancer Humectant

Science

Mechanism of Action

This block copolymer is meticulously engineered, consisting of polyethyleneimine (PEI-14) segments combined with an average of 24 moles of ethylene oxide (PEG-24) and 16 moles of propylene oxide (PPG-16). Its primary mechanism in formulations is to act as an anticaking agent, ensuring solid particles remain dispersed and preventing clumping. Additionally, the PEG and PPG components contribute to its function as an emulsifier, stabilizing oil and water phases, a conditioning agent to improve skin feel, and a surfactant for cleansing. These glycol components are also recognized for their roles as solubilizers, solvents, consistency enhancers, and humectants, generally promoting good skin tolerance.

Stability

Polyethylene glycols (PEGs) and their derivatives, key components of this copolymer, are generally stable, exhibit good skin tolerance, and are not typically prone to microbiological degradation, often negating the need for specific preservatives.

Safety

Safety Profile

CIR Status
Insufficient data
Sensitization risk Unknown

Specific safety evaluations from the Cosmetic Ingredient Review (CIR) or Scientific Committee on Consumer Safety (SCCS) are currently unavailable for PEI-14 PEG-24/PPG-16 Copolymer. The Environmental Working Group (EWG) rates it with 'LOW' concern across categories including cancer, allergies & immunotoxicity, and developmental/reproductive toxicity. However, the manufacturing process of such polymers may introduce impurities like ethylene oxide, and propylene oxide, a component of the PPG segment, has been noted for its potential to cause skin irritation.
