GB/T 13531.6-2018 《General methods on determination of cosmetics—Determination of partical size》 Related products

This part of GB/T 13531 specifies the determination method of cosmetic granularity (fineness), which is suitable for the determination of granularity of powdery and granular cosmetics. By sieving samples using a standard sieve, calculate the percentage of the particle mass that passes through the sieve to the total mass of the sample to evaluate the uniformity and distribution of cosmetic particles. This standard provides an important mass detection method for the cosmetic industry to ensure that products meet relevant technical requirements and market standards.
