GB/T 13531.6-2018 specifies a method for determining the particle size (fineness) in cosmetics (such as creams, emulsions, foundations, etc.), primarily using a fineness gauge. The method involves scraping the sample across a polished plate with a wedge-shaped groove and observing the scale value at the point where particles appear, thereby assessing the dispersion uniformity and fineness of the product.
