Methylglucamine

Product Description

Green Stone Swiss supplies cosmetic-grade methylglucamine (N-methyl-D-glucamine) with batch COA traceability for transparent gel and hair-care neutralization programs. Direct factory access supports flexible MOQ from lab trials to bulk powder drums.

This sugar-derived primary amine donates mild alkalinity to unlock crosslinked acrylate polymer networks without the clouding or nitrosamine concerns linked to sodium hydroxide or triethanolamine. Water solubility and low volatility suit cold-process aqueous gels, mascaras, and styling bases.

Formulators replacing TEA and inorganic alkalis adopt methylglucamine for carbomer neutralization, electrolyte-tolerant clarity, and CosIng-listed hair-conditioning support—delivering compact INCI labels in sulfate-free and sensitive-skin cleansing systems.

Product Specification

• INCI Name: Methylglucamine
• CAS No.: 6284-40-8

• Standard Packaging: 1 kg, 25 kg fiber drum options (Typical)
• Storage: Keep sealed in cool, dry area; hygroscopic—protect from moisture and CO₂ exposure
• Regulatory Status: CosIng hair conditioning; permitted cosmetic alkalizer; primary amine avoids TEA/DEA nitrosamine pathways
• Quality & Testing: Typical assay ≥99%; water ≤0.5%; heavy metals per cosmetic grade; COA/SDS on request
• Compliance Note: For cosmetic use only. Titrate to target pH; avoid direct neutralization of concentrated AHA/BHA concentrates.

Key Benefits & Applications

Methylglucamine serves as a mild organic alkalizer for aqueous gels, emulsions, and hair-styling matrices requiring transparent rheology and TEA-free pH control.

• Acrylate Gel Neutralization: Converts acidic crosslinked acrylate networks into clear, viscous gels without NaOH-induced precipitation or haze in water-based serums.
• TEA-Free pH Control: Primary amine sugar backbone provides predictable alkalization at 0.1–0.8% while avoiding secondary-amine nitrosation risks associated with triethanolamine.
• Hair Combability Support: CosIng-listed hair-conditioning function improves detangling and after-feel in styling gels, mascaras, and rinse-off conditioners at low use levels.

Formulation Guidelines

Methylglucamine suits cold- or warm-process aqueous systems where mild alkalization must preserve polymer clarity and sensory tolerance.

• Recommended use level: 0.1–0.8% for acrylate neutralization; titrate to target pH rather than fixed percentage loading.
• Optimal formula pH: Neutralize acidic thickeners to finished pH 5.5–7.5; reserve alkalinity headroom for electrolyte-containing bases.
• Processing: Pre-dissolve in water phase; add slowly to dispersed polymer with gentle stirring to prevent lumping.
• Compatibility: Compatible with carbomers, acrylate crosspolymers, and most nonionic emulsifiers; avoid strong oxidizers.
• Caution: Hygroscopic powder—reweigh after storage; do not substitute 1:1 for NaOH without pH recalibration.
• Synergy: Boost transparent gel clarity by neutralizing Acrylates/C10-30 Alkyl Acrylate Crosspolymer with methylglucamine at 0.2–0.6% in aqueous serums.
