3. Key Features
- Acts as an emulsifier, thickener, and stabilizer in oil-in-water (O/W) systems.
- Self-emulsifying grades (GMS-SE) enhance spreadability.
- Non-ionic, compatible with most surfactants.
- Provides pearlescent effects in shampoos and creams.
4. Applications
Cosmetics & Personal Care
- Creams/Lotions: Stabilizes emulsions, improves texture.
- Hair Care: Adds gloss, reduces static.
- Makeup: Used in foundations and lipsticks.
- Typical Use Level: 1-5% in formulations.
Food Industry
- Bakery: Improves dough stability and shelf life.
- Dairy: Used in ice cream for texture.
- Confectionery: Prevents sugar crystallization.
- Food Grade: Generally recognized as safe (GRAS) by FDA (21 CFR 184.1324).
Pharmaceuticals
- Tablet binder, emulsifier in ointments.
5. Handling & Storage
- Storage: Keep in airtight containers below 25°C, away from moisture and direct sunlight.
- Shelf Life: 24 months if stored properly.
- Handling: Avoid inhalation of dust. Use gloves and goggles when handling hot/melted GMS.
6. Formulation Guidelines
- Emulsification: Combine with water and heat to 60-70°C for even dispersion.
- Compatibility: Works with fatty alcohols, silicones, and nonionic surfactants. Avoid strong acids/bases.
- Thickening: Acts synergistically with cetyl alcohol or stearic acid.
7. Regulatory & Safety
