Dodecyl Glycol-CAS 4536-30-5
Dodecyl Glycol is a high-purity mild alkyl glycol cosmetic functional raw material, integrating moisturizing, solubilizing and auxiliary antiseptic functions.
Different from traditional single-function glycol ingredients, it has both hydrophilic and lipophilic groups, with excellent oil-water co-solubility, which can effectively solubilize insoluble essential oils, flavors and functional ingredients in water-based formulas, avoiding formula delamination and turbidity.
Meanwhile, it has mild broad-spectrum bacteriostatic and preservative-assisted effects, which can synergize with mainstream preservatives to improve formula anti-corrosion ability and reduce the dosage of single preservative.
With ultra-mild properties, good skin affinity and no irritation, it can moisturize and soften the skin, optimize product skin feel, and maintain stable activity in conventional cosmetic high-temperature production processes.
It is a multi-functional efficient additive for high-end mild and clean beauty formulas.
Key Benefits
• Three-in-one Multi-function: Integrates moisturizing, solubilization and auxiliary antisepsis, replaces multiple single-function additives, simplifies formula system and reduces production cost.
• Excellent Solubilizing Performance: Efficiently solubilizes essential oils, plant extracts and lipophilic functional components, keeps water-based formulas clear and transparent without delamination.
• Mild Auxiliary Preservative: Inhibits common cosmetic bacteria and molds, synergizes with phenoxyethanol and other preservatives to enhance anti-corrosion effect and extend shelf life.
• Skin-friendly Moisturizing: Softens skin texture, improves dry and rough skin, non-sticky after use, optimizes product touch and avoids dry tightness.
• Strong Formula Stability: Stable in pH 4.0-9.0 and high-temperature processing, no discoloration or precipitation, compatible with all surfactant systems.
• Global Safe Compliance: Low irritation, no sensitization, compliant with EU, FDA and China cosmetic regulations, safe for long-term formula addition.
Applications
• Facial Skin Care Series: Transparent toner, moisturizing essence, lotion, cream, facial mask and daily hydrating skin care products.
• Cleaning & Washing Series: Mild facial cleanser, shampoo, body wash, foam cleansing products, suitable for transparent cleansing formulas.
• Aromatic Functional Products: Essential oil water, floral water, fragrance lotion, transparent aromatic skin care and body care formulas.
• Sensitive Skin Care Series: Low-irritation soothing formulas, sensitive skin maintenance products, mild clean beauty systems.
• Water-oil Compound Formulas: Micro-emulsion products, light cream lotion, functional formulas containing lipophilic active ingredients.
• Long-shelf Daily Chemicals: Daily skin care and body care products that need to extend shelf life and optimize anti-corrosion system.
