Problems solved by technology

[0004] The downside of this product is that using ammonium hydroxide to provide alkalinity releases a lot of ammonia which gives a very unpleasant smell
These attempts either (a) failed to provide adequate hair color reduction, or (b) when the kit components including powdered activator of alkali metal persulfate, hydrogen peroxide developer, and monoethanolamine alkalizing agent were used in the dressing Excessive foaming (also known as "hair puffing" or "hair swelling") when mixed in a container

Embodiment 1

[0056] The product of Example 1 is a conventional product because it contains ammonium hydroxide as the alkalizing agent in the alkalizing agent component. A strong ammonia smell is easy to notice when the components are mixed. The product of Example 2 contained only monoethanolamine as the alkalizing agent in the alkalizing agent component, but no ammonium persulfate. When the three components are mixed together, a lot of foam is produced.

[0057] The products of Examples 3 and 4 produced no detectable ammonia odor and produced little or no foam when the components were mixed. Hair treated with these products will lighten considerably in less than 45 minutes.

Abstract

The present invention relates to a substantially ammonia free hair bleach product. Specifically, the invention concerns hair bleach products that comprise a hydrogen peroxide developer; a powder activator containing a mixed persulfate oxidizing system, and a monoethanolamine alkalizing agent.

Description

field of invention [0001] The present invention relates to hair bleaching products which are substantially free of ammonia. In particular, the present invention relates to hair bleaching products comprising a hydrogen peroxide developer, a powdered activator comprising a mixed persulfate oxidation system, and a monoethanolamine alkalizing agent. Background of the invention [0002] Hair bleaching is a well-known method in the hairdressing field. Hair bleaching involves the application of oxidizing agents to the hair for an effective period of time to achieve the desired reduction in hair color. The oxidizing agent is typically a solution of hydrogen peroxide at a concentration of 6% to 12% by weight. This hydrogen peroxide is applied to the hair at an alkaline pH and gradually lightens the color of the hair by oxidizing the melanin pigment that gives the hair its color. Typically 28% ammonium hydroxide is added to the peroxide solution during application to provide the hi...
