What Is PEG/PPG-25/25 DIMETHICONE/ACRYLATES COPOLYMER?
Silicone-based water-soluble copolymer formed by grafting polyethylene glycol (PEG) and polypropylene glycol (PPG) chains onto a dimethicone backbone. With balanced PEG/PPG ratios (25/25), it provides versatile emulsification for both O/W and W/O systems.
Key Skin Benefits
+ Stabilizes oil-water mixtures — prevents phase separation in emulsions
+ Imparts a smooth, silky after-feel — reduces tackiness of other ingredients
+ Provides mild, non-stripping cleansing — suitable for sensitive skin
Pros
+ Generally well-tolerated — CIR-reviewed as safe for cosmetic use
+ Non-comedogenic — does not clog pores
+ Water-dispersible — easier to formulate than pure silicones
+ Lightweight conditioning — does not weigh hair or skin down
Cons
− Limited independent research — most safety data from CIR panel review of the class
− Synthetic origin — not suitable for natural/organic formulations
− PEG-containing — trace 1,4-dioxane possible if poorly purified (rare in cosmetics)
