POLYGLYCERYL-2 DIPOLYHYDROXYSTEARATE: Advanced Plant-Derived Emulsifier for Ultra-Stable W/O Formulations

PEG-Free · Cold-Process Compatible · Global Compliance

NIKOO's Polyglyceryl-2 Dipolyhydroxystearate (INCI: *Polyglyceryl-2 Dipolyhydroxystearate*, CAS 144470-58-6; 156531-21-4) is a plant-sourced, non-ionic emulsifier engineered for superior water-in-oil (W/O) stabilization. With ultra-low hydrophile-lipophile balance (HLB 4.7), this amber viscous liquid delivers exceptional emulsion stability, sensory elegance, and regulatory compliance—ideal for luxury skincare, sunscreens, and sensitive-skin formulations

POLYGLYCERYL-2 DIPOLYHYDROXYSTEARATE has emulsifying, dispersing, stabilizing, conditioning, and viscosity control properties. In cosmetics, POLYGLYCERYL-2 DIPOLYHYDROXYSTEARATE can be used alone as an emulsifier. It is environmentally friendly and safe, contains no EO structure, exhibits excellent skin compatibility and is non-irritating, is non-selective for the polarity of oils and esters, and can be cold-blended. POLYGLYCERYL-2 DIPOLYHYDROXYSTEARATE is primarily used in creams, cleansers, soaps, shampoos, and lipsticks as an emulsifier, dispersant, wetting agent, solubilizer, and stabilizer, significantly improving product quality.

Performance Advantages

● Excellent emulsifying properties, suitable for both oil-in-water (O/W) and water-in-oil (W/O) formulations. Its strong emulsifying ability allows it to function as a standalone emulsifier, emulsifying a larger amount of water with a smaller amount of oil phase. It is suitable for formulations of water-in-oil creams, lotions, foundations, and other products. Its exceptional performance allows W/O products to have an oily, non-greasy feel.

● Suitable as a co-emulsifier in water-in-oil systems, it exhibits excellent compatibility with various water-in-oil emulsions (including silicone-in-water emulsifiers).

● Epoxy-free, made from plant-derived raw materials, it is green, safe, and non-irritating to the skin, making it suitable for the production of baby skincare products.

● Excellent dispersibility and stability of pigments and titanium dioxide, making it ideal for water-in-oil foundations, creams, and physical sunscreens.

● Suitable for cold-blending processes, it is suitable for formulations incorporating multiple active ingredients.

Core Applications & Benefits

Performance Excellence

• Ultra-Stable W/O Emulsions:
  

Stabilizes high water-content systems (up to 80% internal phase) for creams, SPF, and foundations, preventing phase separation under thermal stress .

Imparts non-greasy, silky textures with rapid absorption (comedogenicity index: 0)

• Pigment & Active Optimization:

Exceptional dispersion of TiO₂/ZnO in mineral sunscreens and foundations, enhancing SPF efficacy and reducing whitening

• Sustainable Processing:

Cold-process compatibility reduces energy consumption by 30% vs. traditional methods 

Applications & Safety

Industry-Specific Uses

Conditions: 25°C max, ≤60% humidity, sealed/light-resistant containers

Safety: Non-irritating; use gloves/goggles during industrial handling
