Glycerin

Product Description

Green Stone Swiss supplies cosmetic-grade Glycerin under a direct factory model, with GMP-aligned quality control, batch documentation, and sample support for global skincare and personal-care formulators.

Glycerin (INCI: Glycerin; CAS 56-81-5) is a trihydric polyol widely used as a humectant, solvent, and skin-conditioning agent. It attracts and binds water in the stratum corneum, helping build hydration, comfort, and formula stability across leave-on and rinse-off systems.

It is a clear, viscous, water-miscible liquid suitable for creams, lotions, serums, cleansers, masks, and oral-care bases when purity and odor specifications match the finished-product brief.

Key Benefits & Applications

Glycerin is a foundational humectant and solvent for professional moisturizing and personal-care formulas.

• Delivers reliable humectancy for deep and everyday skin hydration concepts
• Supports skin-conditioning feel in leave-on creams, lotions, gels, and serums
• Acts as a polar solvent / co-solvent for water-phase actives and extracts
• Helps manage viscosity and product plasticity in aqueous and emulsion systems
• Typical use level: Suggested 1–10% in most leave-on skincare; higher levels are Formulation-dependent (monitor stickiness and sensory)

Formulation Guidelines

Use these notes to place Glycerin cleanly in water-phase hydration systems.

• Suggested Use Level: Suggested 1–10% for most leave-on skincare; rinse-off and high-glycerin concepts are Formulation-dependent
• Phase: Add to the water phase; fully dissolve/mix before emulsification or gelling
• Sensory: Above ~10%, monitor tack and drag; balance with emollients, esters, or silicone alternatives as needed
• Compatibility: Broadly compatible with humectants, thickeners, surfactants, and common preservatives; confirm odor and color in sensitive clear systems
• Humidity note: In very low-humidity environments, pair with occlusives/emollients to support lasting comfort
• Combine with Sodium Hyaluronate Crosspolymer for layered humectant performance in premium hydration serums and emulsions.
