3. Key Properties & Benefits
Ready‑to‑use inverse emulsion, no neutralization required, no pre‑dispersion needed
Suitable for cold‑process & hot‑process manufacturing；instant thickening once added into water phase
Wide pH stability range: pH 3.5‑11.5, compatible with AHA/BHA, retinoids, alcohol‑rich systems, sun‑filters and pigments
Self‑emulsifying O/W performance, works independent of oil‑phase HLB value; can be used alone or combined with other emulsifiers
Excellent suspension capacity for physical sunscreen, pigments and fine powders
Shear‑thinning rheology: easy spreading, silky non‑sticky skin feelTolerant to moderate electrolytes, good thermal‑cycling stability
4. Recommended Application & Dosage
Recommended dosage in finished cosmetic formula: 1.0‑3.0 % w/w
Cream‑gel, moisturizing lotion & cream
Sunscreen lotion / cream (physical UV filter suspension)
Hydro‑alcoholic gel, hand sanitizer gel
Facial mask, mud mask, leave‑on skincare products
Color cosmetic base
Operation tip: Add under moderate stirring into aqueous phase; avoid high‑shear over‑homogenization which may damage viscosity performance.
5. Compatibility
✅ Compatible: glycols, alcohols, esters, silicone oils, most cosmetic actives, neutral & non‑ionic raw materials
⚠️ Avoid strong anionic polymers at high concentration; high concentration of strong electrolytes may reduce viscosity
6. Storage & Shelf‑life
Storage condition: Keep tightly sealed in cool, dry, well‑ventilated place; avoid direct sunlight, temperature 5‑35 ℃
Shelf‑life: 24 months under original unopened package
Package: 35 kg plastic drum (standard export packing)
7. Handling Notes
For cosmetic raw‑material use only, not for pharmaceutical or food direct application
Avoid contact with eyes; in case of eye contact, rinse thoroughly with plenty clean water
