Products Description
Next-Generation Cooling Synergy Without Compromise
WS-23 Powder is a high-purity synthetic cooling agent engineered to deliver a smooth, non-irritating coolness (15-30 minutes duration) without the bitterness or pungency of traditional menthol. Sourced from ISO-certified facilities in China, our WS-23 exhibits exceptional thermal stability (resists degradation at 200°C), making it ideal for baked goods, e-liquids, and heat-processed cosmetics. With zero odor interference and low dosage efficacy (30-100 ppm), it enhances product formulations while complying with FEMA 3804 and EINECS 256-974-4 standards.
Quality Control
- Batch Testing:
-Purity (HPLC): ≥99%.
-Contaminants: Heavy metals (Pb/Cd/As ≤0.5 ppm), pesticides (510-residue scan).
-Microbiological: TPC <500 CFU/g; absent of E. coli/Salmonella.
- Stability Tests: Accelerated aging (40°C/75% RH for 6 months) to verify shelf life.
- Certificates: COA, MSDS, TDS, ISO 9001 traceability per batch.
