Methyl Gluceth‑20

Product Description

Green Stone Swiss supplies cosmetic-grade methyl gluceth-20 with batch COA traceability for leave-on humectant and sensory programs. Direct factory sourcing supports flexible MOQ from lab trials to bulk liquid drums.

This corn-derived PEG-20 methyl glucose ether is a water-soluble, non-ionic polyol humectant listed in CosIng for moisturising functions. Its moderate viscosity and non-tacky after-feel suit emulsion creams, sunscreen bases, and hydroalcoholic toners where sustained formula moisture is required.

Unlike lighter gluceth grades favored in water-light serums and cleansing foams, methyl gluceth-20 targets dry-skin lotions, soap bars, and SPF moisturizers—helping formulators soften tack, reduce rinse-off defatting, and maintain comfortable skin feel without heavy occlusive loads.

Key Benefits & Applications

Methyl gluceth-20 serves as a leave-on humectant carrier for emulsion creams, sunscreens, and hydroalcoholic bases where sustained moisture feel and formula tolerance are priorities.

• Leave-On Humectant Support: Supports water retention and comfortable after-feel in dry-skin creams, SPF moisturizers, and daily body lotions at typical 0.5–5% use levels.
• Non-Tacky Formula Feel: Imparts smooth, low-tack spread in emulsion and hydroalcoholic systems without adding heavy occlusive drag.
• Reduced Rinse-Off Defatting: When used in liquid soaps and cleansing bases, helps soften the stripped-skin sensation common in high-surfactant rinse-off formulas.

Formulation Guidelines

Methyl gluceth-20 fits leave-on emulsions and SPF bases where moderate-viscosity humectancy and sensory tolerance outweigh the need for ultra-light texture.

• Recommended use level: 0.5–5% in creams and lotions; 1–4% in sunscreens; 0.5–3% in hydroalcoholic toners.
• Optimal formula pH: 5.0–7.5 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 and toners.
• Compatibility: Works with glycerin, other polyol humectants, and nonionic emulsifiers; mild co-solubilization for lipophilic actives.
• Caution: Higher viscosity than low-PEG gluceth grades—balance total humectant load to control formula drag.
• Synergy: Boost SPF moisture feel by co-adding Hyaluronic Acid at 0.5–2% with gluceth-20 in dry-skin sunscreens.
