It has emerged that residues of hydrogen peroxide in human hair result in oxidation damage. This can be prevented with a water-soluble product which is in the form of a powder or tablet and which preferably contains 5 to 50 per cent by weight of ascorbic acid or the salts or derivatives thereof. The ascorbic acid, which is coated, for example, with silicone or ethylcellulose, can be stored in a formulation of this type for a relatively long time and dissolved in water only when used. This can take place with the aid of sodium bicarbonate with an effervescent action. A hair-care composition of this type is extremely well tolerated by hair and skin. |
