Cosmetic Grade Polyethylene Glycol

Cosmetic grade PEG is commercially available in a broad range of molecular weights, including PEG-200, PEG-300, PEG-400, PEG-600, PEG-1000, PEG-1500, PEG-2000, PEG-4000, PEG-6000, and PEG-8000. Low molecular weight grades are clear liquids, medium grades are soft solids or waxy materials, and higher molecular weight PEGs are supplied as white flakes or powders, allowing precise selection based on formulation needs. In cosmetic and personal care products, low molecular weight PEGs such as PEG-200 to PEG-400 are commonly used as humectants, solvents, emollients, and fragrance carriers in creams, lotions, serums, shampoos, body washes, and liquid cosmetics. Medium molecular weight PEGs including PEG-600 to PEG-2000 function as emulsifiers, dispersants, binders, and texture modifiers, helping to improve product stability, spreadability, and skin feel.

High molecular weight PEGs such as PEG-4000 to PEG-8000 are used as thickeners, film-formers, slip agents, and viscosity regulators in balms, sticks, solid cosmetics, and specialty personal care formulations. Molecular weights typically range from 200 to over 8,000 g/mol, directly influencing melting point, viscosity, water solubility, and sensory performance.

Key properties of cosmetic grade polyethylene glycol include excellent skin compatibility, non-greasy feel, high water solubility, low odor, chemical stability, and compatibility with a wide range of cosmetic ingredients. Supplied in cosmetic-approved packaging with full quality documentation, cosmetic grade PEG provides formulators with a reliable, safe, and cost-effective ingredient for creating high-quality, stable, and consumer-preferred personal care products.
