Particle size	99% through 80 mesh or 92% through 200 mesh
Viscosity	≥600
Shearing property	≥6.5
Moisture	≤15%
Ash	≤16
Total nitrogen	≤1.5%
Pyruvic acid	≥1.5%
Lead	≤2ppm
Total plate count	≤5000cfu/g
Yeast	≤500cfu/g
E.coli	≤30cfu/g
Salmonella	Negtive

Excellent Rheology Modifier and Stabilizer:
- Thickening & Suspension: It significantly increases the viscosity of products like shampoo, shower gel, hand soap, liquid cleansers, and facial washes. It also suspends particles (e.g., scrubbing beads, moisturizing microspheres) to prevent separation.
- Emulsion Stabilization: In creams, lotions, and sunscreens, it helps stabilize oil-water mixtures, preventing phase separation and extending product shelf life.
- Improved Texture: Provides a smooth, easy-to-spread sensory experience without a sticky feel.
Good Compatibility:
- Works well with common cosmetic ingredients like salts, surfactants, and other thickeners.
Good pH Stability:
- Remains stable and effective across the typical pH range of cosmetic products (pH 3-12).
High Purity and Safety:
- While its specifications for heavy metals and microorganisms may not be as stringent as food-grade, cosmetic-grade still requires high purity, low impurities, and must be non-irritating to skin and eyes, complying with cosmetic ingredient safety regulations.
  
  Common Product Applications
  - Hair Care: Shampoo, conditioner (adds viscosity, stabilizes nutrients, improves foam and combability).
  - Facial Care & Skincare: Facial cleansers, toners, serums, creams, masks (especially gel-type masks for texture and ingredient suspension).
  - Body Care: Body wash, body lotion, deodorant.
  - Oral Care: Toothpaste (as a binder and thickener to stabilize the paste).
  - Household Cleaners: Used as a thickener in some premium liquid detergents and hand soaps to prevent settling of active ingredients.
  Difference from Food-Grade Xanthan Gum
  - Standards Differ:
    - Food Grade: Must comply with strict food safety standards like GB 1886.41 (China), FDA (USA), or EFSA (Europe), with tight limits on heavy metals, microorganisms, and solvent residues.
    - Cosmetic Grade: Primarily follows regulations like China’s Cosmetic Safety Technical Specifications or similar international cosmetic ingredient standards. The focus is different, but safety is equally required.
  - Cost Difference: Food-grade typically has higher production costs due to stricter standards.
  - Application Context: The two grades are not interchangeable. Food manufacturers must use food-grade materials, while cosmetic manufacturers choose cosmetic-grade ingredients that comply with cosmetic regulations, based on product needs and cost.
