2. Alcohol Content Testing in Cosmetics
To meet the increasing demands of clients, QUATEST 3’s Chemical Testing Laboratory has optimized a gas chromatography method with flame ionization detection (GC-FID) for simultaneous quantification of four alcohols: methanol, ethanol, 1-propanol, and 2-propanol.
This method offers high selectivity and resolution, which is suitable for analyzing personal care products (e.g., alcohol wipes, makeup removers) and cosmetic formulations (e.g., mouthwash, feminine hygiene solutions, serums, lotions, hand sanitizers).
The detection limit is 30 mg/kg, complying with national and international standards such as TCVN 6971:2001, Circular 06/2011/TT-BYT, and WHO disinfectant guidelines.
3. Analysis of Controlled Active Ingredient – Tretinoin
QUATEST 3 has developed a High-Performance Liquid Chromatography method with UV detection (HPLC-UV) to test for tretinoin, an active ingredient in skincare, acne treatment, and whitening products.
- The method complies with TCVN 13642:2023 and ASEAN’s ACM 001 standard.
- Detection limit: 5 mg/kg.
- Applicable across various product types including serums, lotions, creams, hygiene solutions, and hair care products.
4. Other Chemical and Microbiological Parameters in Cosmetics
QUATEST 3 offers comprehensive testing services aligned with ASEAN, Vietnamese (TCVN), and international standards, covering:
