Abstract

DC60 (23/07/51) This invention shall be a method for the dyeing or bleaching of hair by dispensing in foam from a squeeze container 6 a mixed solution of the first actuator A1 and the second actuator A2 of a two-part hair dye or bleaching composition for application to the hair. In this invention, a squeeze container, including the body 4 and the foaming squeeze device 5, shall be used as squeeze container 6. At least the first actuator A1 or the second actuator shall contain the foaming agent. The mixed solution of the first and second actuators shall have a viscosity (25 °C) of 1 mPa•S to 100 mPa•S. The first actuator A1 and the second actuator A2 shall be mixed in the body 4 in a non-foaming manner. Dispensing shall be done with an upright squeeze container 6 as described above. The mixed solution A3 does not reach the air inlet 12 of the squeeze foaming device 5. As a result, the mixed solution of the first and second actuators of a two-part hair dye or bleaching composition can be uniformly dispensed by using the squeeze container in fine foam. This invention provides a method for hair dyeing or bleaching by dispensing in foam from a squeeze container 6 of a mixed solution of the first actuator A1 and second actuator A2 of a two-part hair dye or bleaching composition for application to the hair. In this invention, the container, which includes the body 4 and the squeeze foaming device 5, is used as the squeeze container 6. At least the first actuator A1 or the second actuator solution contains a foaming agent. The mixed solution of the first and second actuators has a viscosity (25 °C) from 1 mPa•s to 100 mPa•s. The first actuator A1 and second actuator A2 are mixed in the body 4 as no foaming occurs. Squeezing is done with an upright squeeze container 6, so that the mixed solution A3 does not reach the air inlet 12 of the squeeze foam generator 5. As a result, the mixed solution of the first and second active ingredients of the 2-part hair dye or bleaching composition can be evenly dispensed using the squeeze container in fine foam.

Claims (8)

1. A two-part hair dye or bleaching compound is applied to hair using a squeeze container in which a mixed solution of the first agent, containing an alkaline agent, and a second agent, containing hydrogen peroxide, is expelled. The squeeze container, which includes the container itself and a squeeze foaming agent, has a gas-liquid mixing chamber for foaming the mixed solution by mixing air within the container with the solution; a foam homogenizing device for homogenizing the foamed solution, which is produced in the gas-liquid mixing chamber; and an expulsion chamber for expelling the homogeneous foam. At least one of the first and second agents contains a foaming agent. The mixed solution of the first and second agents has a viscosity (25°C) of between mPa•s and 100 mPa•s. The first and second agents are mixed within the squeeze container as they do not foam, and the squeeze is performed with the squeeze container upright as they do not foam. Reach the air vents of the squeeze foam generator. 2. Two-part hair dye or bleaching compounds as per Patent 1, where the cycle of movement of the container holding the first and second acting agents from a roughly upright position to a sideways inverted position and then back to a roughly upright position again is performed by mixing the first and second acting agents 1 to 15 times at a speed of 1 to 30 times per 10 seconds. 3. A two-part hair dye or bleaching compound as per Patent 1, where the time required for one squeeze ranges from 0.5 seconds to 5 seconds. 4. Two-part hair dye or bleaching compounds as per claim 1 where the squeeze container can expel its contents in an upright manner. 5. Two-part hair dye or bleaching compounds as per claim 4, where the squeeze is performed while the angle formed between the upright direction of the squeeze container and the horizontal direction is between 0° and 60°. 6. Two-part hair dye or bleaching compounds under claim 1 where the mixed solution, expelled in foam, is applied from the hairline or parted hair area. 7. Two-part hair dye or bleaching compounds as per Patent 1, where the mixed solution released into the foam is applied to the hair or parted hair area in greater quantities than other areas. 8. A two-part hair dye or bleaching compound as per claim 1, in which the mixed solution, expelled in foam, is rubbed onto the hair.
