Abstract

The cosmetic care preparation has a first component and a second component kept separate from the first component prior to application, which are mixed immediately prior to application on the hair and/or skin to form a ready-to-use product. The first component includes at least one conditioning ingredient, preferably one or more fats, oils and/or waxes, and the second component is a cationic or anionic base emulsion that includes at least one lipophilic substance, at least one cationic or anionic emulsifier, at least one organic acid and water. In a particularly preferred embodiment, the first component includes at least one cationic surfactant and/or at least one cationic polymer and the second component includes at least one monoalcohol and/or at least one amphoteric or nonionic surfactant. The first and the second components are mixed in a ratio of 20:1 to 1:20 to obtain the ready-to-use product but within that range of weight ratios the relative proportions of the first and second components can be adjusted to match a particular skin and/or hair type or quality.
