DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to the use of a preparation for preventing the coloring of skin when dyeing the hair, novel skin protection compositions, and a process for dyeing hair with the use of these skin protection compositions or said preparation.
When dyeing hair, even when the hair dye composition is applied with utmost care, coloring of the skin cannot always be avoided. This coloring of the skin is particularly unsightly and annoying on the visible parts of the skin directly adjoining the hairline.
Numerous so-called color-spot removers are known which can be employed after the hair dyeing treatment is concluded for removing the spots of color. Regardless of the composition employed, subsequent removal of spots of color is always irritating to the skin due to the cleaning materials contained in the compositions and the mechanical rubbing which is generally required to remove the spots of color. In addition, these color-spot removers are often not capable of entirely eliminating the color from the skin once it has occurred.
Therefore, to prevent the coloring of skin when dyeing hair, skin creams in the form of oil-in-water emulsions or water-in-oil emulsions and petrolatum are applied directly to the skin adjoining the hairline before beginning the dyeing treatment.
However, it has been shown that the use of skin protection compositions in the form of emulsions, particularly in hair dyeing treatments with dark, color-intensive shades, does not adequately protect the skin from coloring and subsequent treatment with a color-spot remover is required.
Vaseline is unsuitable as protection against coloring of the skin when dyeing the hair, since its insolubility in water makes it very difficult to remove again from the skin adjoining the hairline without the use of organic solvents such as acetone or benzene.
Therefore, the problem is posed of providing a preparation of use in preventing the coloring of skin when dyeing or tinting hair which is easy to apply and safely protects the skin adjoining the hairline from being colored when dyeing or tinting the hair. It should be possible to remove this preparation easily and completely with water after the dyeing treatment or after tinting and the preparation should also be tolerated well by the skin.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a new process of dyeing hair as well as compositions to prevent skin coloring and to protect skin during dyeing with improved qualities.
Surprisingly, it has now been found that the problem specified above is solved in an outstanding manner by the use of a preparation which is characterized in that it contains a combination of molecular weight of 2700 to 7500, to 60 moles ethylene oxide, polyethylene glycol with a molecular weight of 100 to 300, and
The subject matter of the present invention is also a skin protection composition which is characterized in that it contains a combination of molecular weight of 2700 to 4800, weight of 5600 to 9000, to 60 moles ethylene oxide, polyethylene glycol with a molecular weight of 100 to 300, and
Due to its highly viscous, waxy, glue-like consistency, the skin protection composition according to the invention ensures an excellent protection against coloring of the skin when dyeing the hair, particularly also when dyeing the hair in dark shades. The skin protection composition can be effortlessly applied in a uniform manner prior to the hair dyeing treatment, is very well tolerated by the skin, and can be removed again easily and completely with water after the hair dyeing treatment.
In a particularly preferred embodiment form, the skin protection composition according to the invention contains molecular weight of 2700 to 4800, weight of 5600 to 9000, to 60 moles ethylene oxide, polyethylene glycol with a molecular weight of 100 to 300, and
In addition to the components (A) to (E) mentioned above, the preparation as well as the skin protection composition according to the invention can also contain conven
