The present invention relates to a hair dye composition which is provided by mixing a first-part agent containing an alkaline agent and a second-part agent containing an oxidizing agent upon application, comprising, after mixing, components (a) to (c) and an oxidative dye (d) as needed, wherein the pH after mixing is 8 to 12 and the content of component (a) is 0.1 to 20 wt.%:
(a) a betaine compound represented by formula (1) and an acid-addition salt thereof:
wherein R1, R2 and R3 are the same or different from one another and each represents a C1-3 alkyl group, X represents a C1-3 alkylene group, Y represents CO2-, SO3-, OSO3- and OPO3-;
(b) an oxidizing agent; and
(c) an ammonia or a salt thereof.
The hair dye composition of the present invention suppresses the stripping of ammonia at the time of mixing a first-part agent and a second-part agent, thereby reducing the unpleasant odor of ammonia upon application. Further, the hair dye composition of the present invention suppresses hair damage and deterioration of feeling without a pre-treatment; has excellent dying and bleaching effects; and uniformly dyes (bleaches) the hair from the root to the tip of the hair regardless of the degree of hair damage.
本发明涉及一种染发组合物,该组合物在使用时通过混合含有碱性剂的第一部分剂和含有氧化剂的第二部分剂而提供,混合后包括组分(a)至(c)和所需的氧化染料(d),其中混合后的pH值为8至12,组分(a)的含量为0.1至20重量%:
(a) 由式(1)代表的甜菜碱化合物及其酸加成盐:
其中 R1、R2 和 R3 彼此相同或不同,各自代表 C1-3 烷基,X 代表 C1-3 亚烷基,Y 代表 CO2-、SO3-、OSO3- 和 OPO3-;
(b) 氧化剂;和
(c) 氨或其盐。
本发明的染发组合物在混合第一部分药剂和第二部分药剂时抑制了氨的剥离,从而减少了使用时氨的难闻气味。此外,本发明的染发剂组合物无需预处理即可抑制头发损伤和感觉变差;具有出色的染色和漂白效果;无论头发损伤程度如何,都能从发根到发梢均匀染色(漂白)。
