    Abstract: A method of colouring keratinous fibers comprising contacting the keratinous fibers sequentially with a pre-treatment composition and a colour developer wherein : i. the pre-treatment composition comprises: (a) 0.5-25% by weight of an iron salt at a pH below 2 including 0.5-5% by weight of a reducing agent (b) a buffer effective in the pH range 3-6 and (c) a penetration enhancer comprising one or more solvents having Hansen solubility parameter δh between 1-10 (MPa) 1/2 and δp between 10-25 (MPa) 1/2 wherein the component (b) is mixed with (a) or (c) not more than 360 minutes prior to contacting the keratinous fibers and ii. the colour developer is selected from one or more of hydrolysable tannin or its breakdown products or derivatives or a mixture thereof obtained from a natural or synthetic source, where the sequence of contact is in any order.

    Abstract translation: 一种着色角质纤维的方法,包括使角质纤维顺序地与预处理组合物和显色剂接触,其中: 预处理组合物包含:(a)0.5-25重量%的低于2的pH值的铁盐,包括0.5-5重量%的还原剂(b)在pH 3-6范围内有效的缓冲剂;和 (c)包含一种或多种溶剂的渗透增强剂,其中Hansen溶解度参数dh在1-10(MPa)1/2和dp在10-25(MPa)1/2之间,其中组分(b)与(a) 或(c)在接触角质纤维之前不超过360分钟,和ii。 彩色显影剂选自一种或多种可天然或合成来源的可水解单宁或其分解产物或衍生物或其混合物,其中接触顺序为任何顺序。
