The standard was divided into four stages, and a case where it was judged that the whiteness of appearance was not felt at all was evaluated as 4, and a case where it was judged that the whiteness of appearance was very felt and practical use was impossible was evaluated as 1.
（動的安定性の評価）
　５０ｍＬの円柱状プラスチック容器に２０ｍＬの化粧料を入れた。これを回転機に取り付け、１０ｒｐｍで回転させた。３時間回転後に化粧料の外観・性状を専門パネラー１名が目視で判断した。基準を４段階にわけ、外観・性状に変化がない場合を４、外観・性状が悪化し、商品として実使用不可と判断した場合を１として評価した。 (Evaluation of dynamic stability)
20 mL of cosmetic material was placed in a 50 mL cylindrical plastic container. This was attached to a rotating machine and rotated at 10 rpm. After rotation for 3 hours, one expert panelist visually judged the appearance and properties of the cosmetics. The standard was divided into four stages, and the case where there was no change in the appearance and properties was evaluated as 4. The case where the appearance and properties deteriorated and it was judged that the product could not be used was evaluated as 1.
