General Description:
PEG-90M (Polyethylene Glycol-90M) is a high-molecular-weight polymer derived from ethylene oxide. It appears as a white, waxy solid or powder and is widely used in cosmetic and personal care product formulations. Known for its thickening, film-forming, and stabilizing properties, PEG-90M enhances product texture and consistency. Available for bulk sales, wholesale supply, and large-scale manufacturing, PEG-90M is a trusted ingredient for brands focused on performance and product stability.
Uses in the Cosmetics Industry:
PEG-90M is commonly used in skincare, hair care, and personal hygiene products due to its ability to improve product feel and performance. It functions as a rheology modifier and moisture-retaining agent. Typical cosmetic applications include:
- for enhanced texture and smooth application.
- to improve spreadability and control viscosity.
- as a binding and thickening agent.
- to stabilize emulsions and improve foam quality.
Its excellent solubility and film-forming abilities make PEG-90M highly desirable for cosmetic manufacturers looking for consistency in high-quality formulations. Buy PEG-90M in bulk to meet production needs efficiently.
Side Effects & Hazards:
PEG-90M is generally considered safe for use in cosmetics. However, in rare cases, it may cause mild skin irritation or allergic reactions, especially in individuals with very sensitive skin. Impurities from improper processing or sourcing may pose safety risks, so it is essential to use only high-purity, cosmetic-grade material.
PEG compounds can increase skin permeability, so care must be taken in formulation when used alongside active ingredients. During manufacturing and handling, proper storage in a cool, dry place and adherence to safety protocols are necessary to prevent degradation and ensure long-term stability.
For safe and effective use, always purchase PEG-90M from trusted wholesale suppliers to maintain the integrity and performance of your cosmetic products.

Warning: Avoid inhalation of dust. Avoid contact with eyes. Use personal protective equipment when handling large quantities. For external use only in cosmetic applications.
THE STORY OF PEG 90M
PEG-90M: The Ultra-High Molecular Weight Polymer for Premium Texture Control
PEG-90M is an ultra–high molecular weight polyethylene glycol known for its exceptional thickening, stabilizing, and slip-enhancing properties. Even at extremely low concentrations, it delivers rich viscosity, smooth flow, and a luxurious cushiony feel — making it a top-tier polymer for advanced skincare and haircare systems.
Engineered Through Precision Polymerization for Maximum Performance
PEG-90M is produced via highly controlled polymerization of ethylene oxide, creating exceptionally long polymer chains responsible for its powerful rheology-modifying effects. After polymerization, the material is dried, milled, and purified to cosmetic-grade standards, ensuring consistency, stability, and high performance in formulation use.
High-Efficiency Thickening with Silky, Elegant Sensory Enhancement
In cosmetics, PEG-90M acts as a high-efficiency thickener, texture modifier, and stabilizer.
It provides exceptional viscosity, prevents phase separation, improves slip, and creates a silky, luxurious sensory profile. It is ideal for serums, lotions, conditioners, gels, masks, and high-performance emulsions requiring refined, cushioned texture.
Potent, Low-Dosage Polymer for Modern Formulation Science
Used in skincare, hair conditioners, serums, treatment gels, and stability-sensitive emulsions.
Recommended usage: extremely low — typically 0.05–1%, depending on viscosity goals.
Store tightly sealed in a cool, dry place.
PEG-90M is non-toxic, stable, and globally approved for cosmetic applications, making it a preferred choice for formulators aiming for elegant textures with high structural integrity.
