Information About Sodium Chloride
✅ Key Features
- Natural mineral salt (NaCl) with high cosmetic purity
- Thickens anionic surfactant systems like shampoos and washes
- Used as a gentle exfoliant in scrubs and salt-based treatments
- Enhances cleansing and purifying properties
- Improves bath salt hardness and skin-softening effects
🔬 Description
Sodium Chloride, also known as cosmetic-grade salt, is a versatile raw material used for its thickening, cleansing, and exfoliating properties. It’s commonly added to shampoos and body washes to increase viscosity and reduce runniness. As a granular exfoliant, it gently removes dead skin cells and purifies the skin. It also serves as the base for bath salts, scrubs, and DIY mineral treatments. Pure, food-grade salt may also help draw out toxins and minerals during soaking rituals.
