阅读说明：本技术 减少漂白剂和着色剂的损伤的粉末添加剂 (Powder additive for reducing damage to bleaches and colorants ) 是由 M·A·斯塔基 H·曼内克 T·希佩 S·史密斯 R·舍夫勒 于 2020-04-29 设计创作，主要内容包括：提供了一种用于角蛋白纤维着色剂或漂白剂或显色剂的粉末添加剂。所述粉末添加剂包括含有约2至约10个碳原子的二羧酸,其选自苹果酸、D-酒石酸、L-酒石酸、内消旋酒石酸、外消旋酸、α-酮戊二酸、β-酮戊二酸、草酰乙酸、马来酸、富马酸、草酸、丙二酸、琥珀酸、戊二酸、己二酸、庚二酸、壬二酸、山梨酸、这些二羧酸的盐,以及它们的混合物。所述粉末添加剂还包括氨基酸或氨基酸的盐和碱式硅酸盐。基于所述粉末添加剂的重量,所述粉末添加剂具有不大于约10重量％的水。此外,所述粉末添加剂包括颗粒,并且所述颗粒的至少约80％具有小于200μm的平均粒径。(A powder additive for keratin fibre colouring agents or bleaches or developers is provided. The powder additive comprises a dicarboxylic acid containing from about 2 to about 10 carbon atoms selected from the group consisting of malic acid, D-tartaric acid, L-tartaric acid, meso-tartaric acid, racemic acid, alpha-ketoglutaric acid, beta-ketoglutaric acid, oxaloacetic acid, maleic acid, fumaric acid, oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, pimelic acid, azelaic acid, sorbic acid, salts of these dicarboxylic acids, and mixtures thereof. The powder additive also includes an amino acid or a salt of an amino acid and a basic silicate. The powder additive has no greater than about 10 wt% water, based on the weight of the powder additive. Further, the powder additive includes particles, and at least about 80% of the particles have an average particle size of less than 200 μm.)
