1. Domestic and International Standards and Regulations: This is the product launch "traffic rules." The training must provide a detailed interpretation of China's "Technical Standards for Cosmetic Safety" and "Instructions for the Use of Consumer Goods," "General Labeling for Cosmetics," and key national standards (GB/T). For example, in recent releases, GB/T 44998-2024 "Determination of Nitrates and Nitrites in Surfactants by Ion Chromatography" and GB/T 45000-2024 "Surfactant Composition Analysis of Sucrose Fatty Acid Esters by Liquid Chromatography," etc. At the same time, it is also necessary to understand the European Union REACH, United States FDA, and international regulations to address the challenges of the globalized market.
2. Fundamental Knowledge of Core Raw Materials Such as Surfactants: In-depth understanding of the definition and classification of surfactants (anionic/cationic/amphoteric/nonionic), structure and properties (HLB value, CMC, Krafft point, cloud point, pour point) is the foundation of formulation design. Training should incorporate case studies to explain the synergistic effects of different surfactants (such as alkyl polyglucosides, betaines, amino acid-based surfactants, etc.) in the system, as well as their impact on the product's cleaning power, foam, viscosity, and irritation.
3. Product Applications and Formulation Principles: For different product types (e.g., shampoo, skincare cream, household cleaners), analyze their formulation architecture, the functions of each component, and their mechanisms of action. For instance, explain how surfactants in shampoo remove oil and dirt while protecting hair strands, or how cationic surfactants in conditioners neutralize static electricity and smooth the hair cuticle.
4. Quality Requirements and Experimental Demonstration: The training must include the detection methods and practical applications of key quality indicators, such as pH value determination, viscosity control, stability testing (centrifugation, high-low temperature cycling), effective content analysis (e.g., using chromatography methods from the new national standards), and product performance evaluation (such as detergency testing, foam performance testing, etc.).
Through this "Theory+Practice" integrated training, practitioners can systematically master the full spectrum of knowledge—from raw material selection and formula design to production quality control and market claims—laying a solid foundation for developing safe, effective, compliant, and market-driven daily chemical products.
