Claims8
A cosmetic composition for coloring the skin having a pH between 2-5 and consisting essentially of a solution containing
- 1. 0.5-12 percent by weight of an aminated aldehyde of the formula ##EQU7## wherein R.sub.1 is selected from the group consisting of hydrogen, methyl and hydroxyethyl, R.sub.2 is selected from the group consisting of hydrogen, methyl, ethyl, propyl, isopropyl, butyl, hexyl, hydroxyethyl, cyclohexyl, benzyl, (1,2-diformyl-2-hydroxy) ethyl and 2-[(1,2-diformyl-2-hydroxy) ethylamino] ethyl and R.sub.1 and R.sub.2 together with the nitrogen atom to which they are attached form piperidinyl;
- 2.

- 3. 0-2 weight percent of silicone oil;
- 4. 0.5-12 weight percent of an aminated aldehyde of the formula ##EQU9## wherein R.sub.1 is selected from the group consisting of hydrogen, methyl and hydroxyethyl, R.sub.2 is selected from the group consisting of hydrogen, methyl, ethyl, propyl, isopropyl, butyl, hexyl, hydroxyethyl, cyclohexyl, benzyl, (1,2-diformyl-2-hydroxy) ethyl and 2-[(1,2-diformyl-2-hydroxy) ethylamino] ethyl and R.sub.1 and R.sub.2 together with the nitrogen atom to which they are attached form piperidinyl;
- and
- 5. the remainder consisting essentially of water.
A cosmetic composition for coloring the skin having a pH between 2-5 and consisting essentially of
- 1. 2-15 percent by weight of a fatty alcohol having 12-18 carbon atoms oxyethylenated with 10-15 moles of ethylene oxide as a surface active agent;
- 2. 0-20 percent by weight of a component selected from the group consisting of light vaseline oil, perhydrosqualene, sweet almond oil, ricin oil, colza oil, olive oil, peanut oil, cocoa oil, palm oil, isopropyl palmitate, isopropyl myristate, fatty alcohol having 16 carbon atoms and saturated fatty acid having 18 carbon atoms;
- 3. 0-6 percent by weight of a thickening agent selected from the group consisting of (A) starch, (B) crosslinked polyacrylic acid having a Brookfield viscosity measured in a 0.5% solution neutralized to a pH of 7 with NaOH of 8,900 - 43,000 centipoises, (C) diethylene glycol stearate;
- 4. 0-15 weight percent glycerine;
- and
- 5. 0.5-12 weight percent of an aminated aldehyde of the formula ##EQU10## wherein R.sub.1 is selected from the group consisting of hydrogen, methyl and hydroxyethyl, R.sub.2 is selected from the group consisting of hydrogen, methyl, ethyl, propyl, isopropyl, butyl, hexyl, hydroxyethyl, cyclohexyl, benzyl, (1,2-diformyl-2-hydroxy) ethyl and 2-[(1,2-diformyl-2-hydroxy) ethylamino] ethyl and R.sub.1 and R.sub.2 together with the nitrogen atom to which they are attached form piperidinyl;
- and
- 6.
A cosmetic composition for coloring the skin having a pH between 2-5 and consisting essentially of a solution in a solvent selected from the group consisting of water and an aqueous alcohol solution wherein the alcohol component is selected from the group consisting of ethanol and isopropanol present in an amount of about 10-90 weight percent of the total composition, of 0.5-12 percent by weight of said composition of an aminated aldehyde selected from the group consisting of 2-ethylamino-3-hydroxy succinic aldehyde, 2-propylamino-3-hydroxy succinic aldehyde, 2-di-.beta.-hydroxyethylamino-3-hydroxy succinic aldehyde, 2-[(1,2-diformyl-2-hydroxy) ethylamino]-3-hydroxy succinic aldehyde, 2[[2-(1,2-diformyl-2-hydroxy) ethylamino]ethyl] amino-3-hydroxy succinic aldehyde and 2-dimethylamino-3-hydroxy succinic aldehyde.
