PEG/PPG-17/6 Copolymer

PEG/PPG-17/6 Copolymer – Multifunctional Non-Ionic Surfactant for Cosmetics and Personal Care

Basic Information

• INCI Name: PEG/PPG-17/6 Copolymer

• CAS Number: 9003-11-6 (generic)

• Appearance: Clear to slightly hazy viscous liquid

• Solubility: Water-soluble, also soluble in many organic solvents

• pH Stability: Stable in the range of 3–8

Overview
PEG/PPG-17/6 copolymer is a synthetic non-ionic block copolymer produced by the random polymerization of ethylene oxide (average 17 moles) and propylene oxide (average 6 moles). This unique structure provides an optimal balance between hydrophilic and lipophilic segments, making it a versatile ingredient in cosmetic, personal care, and pharmaceutical formulations. It functions as a solubilizer, emulsifier, wetting agent, humectant, and viscosity reducer.

Key Properties

• Solubilizer and emulsifier: Effectively dissolves oils, fragrances, and active ingredients, stabilizing clear and emulsion systems.

• Viscosity reducer: Lowers the viscosity of formulations, improving flow and ease of application.

• Wetting and spreading: Enhances wetting of skin and hair, providing better coverage and uniform distribution.

• Humectant and emollient: Attracts moisture and imparts a smooth, silky, non-greasy feel to the skin.

• Anti-foaming: Helps control foam in surfactant-based systems.

• Mild and safe: Low irritation potential, non-toxic, suitable for sensitive skin.

• Broad compatibility: Compatible with a wide range of cosmetic ingredients and stable across pH 3–8.

Applications

• Skin care: Lotions, creams, serums, facial toners, and moisturizers – improves spreadability, reduces tackiness, and enhances hydration.

• Hair care: Shampoos, conditioners, and hair lotions – provides conditioning and smoothness.

• Color cosmetics: Foundations, mascaras, and makeup removers – improves pigment dispersion and cleansing efficacy.

• Antiperspirants and deodorants: Provides emolliency and slip.

• Sunscreens: Enhances spreadability and water resistance.

• Other: Used as a glycerin substitute in various formulations.

Recommended Use
Typical usage levels range from 1–10% in both rinse-off and leave-on products. The optimal concentration depends on the desired viscosity reduction, solubilization, and sensory properties. Easily incorporated into aqueous or emulsion systems at room temperature or with mild heating.

Safety and Handling

• Generally recognized as safe for use in cosmetics at recommended concentrations.

• Low irritation potential; well-tolerated by skin and eyes.

• Avoid contact with strong oxidizers.

• Store in a cool, dry place, away from direct sunlight.

• Use appropriate personal protective equipment (gloves, safety goggles) when handling.

Quality Assurance
Each batch is tested for purity, viscosity, and pH to ensure consistent performance.
