Methyl Gluceth‑10

Product Description

Green Stone Swiss supplies cosmetic-grade methyl gluceth-10 with batch COA traceability for lightweight humectant and sensory programs. Direct factory sourcing supports flexible MOQ from lab trials to bulk liquid drums.

This corn-derived PEG-10 methyl glucose ether is a water-soluble, non-ionic polyol listed in CosIng for humectant, moisturising, and emulsifying functions. Its lower ethoxylate degree and fluid viscosity suit water-light essences, facial cleansers, and shaving foams where low-tack slip is required.

Formulators targeting rinse-off cleansing bases and cold-process gels adopt methyl gluceth-10 to soften glycerin tack, support mild lipophile co-solubilization, and lower freezing points—positioning distinct from higher-PEG gluceth grades used in richer leave-on creams and SPF moisturizers.

Key Benefits & Applications

Methyl gluceth-10 serves as a lightweight humectant carrier for water-light serums, cleansing gels, and shaving foams where low tack and formula tolerance are priorities.

• Water-Light Humectant Carrier: Supports comfortable moisture retention in essences, toners, and daily lotions at typical 0.5–5% use levels without heavy occlusive drag.
• Glycerin Tack Softening: Co-formulated in glycerin-rich bases, reduces sticky after-feel while maintaining formula clarity in cold-process aqueous gels.
• Cleansing Foam Sensory Aid: In facial cleansers and body washes, helps soften foam hand-feel and moderates surfactant-related defatting sensation in rinse-off systems.

Formulation Guidelines

Methyl gluceth-10 fits water-light and rinse-off systems where fluid humectancy, tack reduction, and mild co-solubilization outweigh richer emollient needs.

• Recommended use level: 0.5–5% as humectant; 1–3% to reduce glycerin tack; up to 8% in cleansing foams.
• Optimal formula pH: 5.0–8.0 for stability; compatible across mildly acidic to neutral skincare bases.
• Processing: Add to water or aqueous phase at 25–60 °C; cold-process compatible in clear gels.
• Compatibility: Works with glycerin, other polyols, and nonionic surfactants; mild co-solubilization for lipophilic actives.
• Caution: High load may soften viscosity in anionic cleanser bases—rebalance surfactant and thickener levels.
• Synergy: Formulators often co-add Hyaluronic Acid at 0.5–1% for stacked humectancy in water-light essences.
