Abstract

The use of certain alkanolamines is disclosed for use as a substitute for some or all of ammonium hydroxide in hair treatment compositions. When used as alkalizing agents for hair coloring agents, these derivatives demonstrate reduced hair fiber damage, effective color lifting, and significant improvements in cytotoxicity and odor compared to well-known substitutes for ammonium hydroxide.

Description

Hair treatment composition having an amine derivative The present invention relates to applications in hair treatment. Specifically, it relates to a substitute for ammonium hydroxide for softening and swelling the hair cuticle and for enabling the penetration of reagents and hair-beneficial active ingredients into the cortex. Hair structure Human hair fibers are generally understood to possess an outermost layer called the cuticle. The cuticle contains approximately 6 to 12 layers of overlapping, flattened keratinocytes arranged in a "fish scale" pattern along the longitudinal direction of the hair fiber. This overlapping cell arrangement allows the cells to slide against each other, providing the hair fiber with a high degree of flexibility without breakage. The cuticle layer also regulates the amount of water within the hair shaft. The outermost surface of the cuticle is coated with lipid substances that make the hair surface hydrophobic. Additionally, the fish scale arrangement and lipid coating of the cuticle impart barrier properties to the hair fiber. The second layer of the hair fiber located beneath the cuticle is the cortex. A natural dye called melanin is found here. Due to the semi-transparent nature of the cuticle, melanin in the cortex is usually visible. The cells of the cortex form a matrix that supports the keratin protein structure. In the cortex, protein filaments composed of long keratin chains are the primary structural components of the hair. These keratin chains are rich in cysteine, a sulfur-containing amino acid, which forms permanent, thermally stable cross-links between the keratin chains in the form of disulfide bridges. Human hair is approximately 14–20% cysteine. The extensive disulfide bonds of cysteine provide about one-third of the hair's strength and generally make it insoluble, except by certain dissociating or reducing agents. softening of the cuticle The present invention relates to softening and swelling the hair cuticle for any purpose, though not limited to, hair relaxation, straightening, perming, strengthening, and dyeing. In various types of hair treatments requiring cuticle swelling and relaxation, ammonia (in solution) is considered the 'optimal standard.' Ammonium hydroxide, an alkalizing agent, raises the pH of the hair, swelling and relaxing the hair cuticle to allow active ingredients and/or reagents to penetrate the hair. However, the use of ammonia has many disadvantages. For example, during use, ammonia gas easily escapes into the surrounding environment, emitting a strong odor and irritating the skin, eyes, nose, and throat. These side effects can be experienced by both the person receiving the hair treatment and the person providing it. Furthermore, ammonia is known to cause damage to hair by breaking peptide bonds. For these reasons, research into alternative cuticle penetration methods has been conducted for decades, but the results have been mixed. For example, aminomethylpropanol (AMP) and monoethanolamine (MEA) have been used as substitutes for ammonium hydroxide due to their low odor. Both molecules are known to be used as pH buffers in cosmetic formulations. In terms of their action on hair, the amine functional group NH2 reacts similarly to ammonia ( NH3 ) in ammonium hydroxide solutions, significantly reducing the ammonia odor. Nevertheless, a significant increase in hair fiber damage is associated with AMP and MEA, which remains a major concern in the relevant technology field. Indeed, to date, no treatment has been found that is as effective as ammonium hydroxide in opening up the cuticle while avoiding or significantly reducing the side effects of odor and excessive hair damage. Hair dyeing treatment Although the principles of the present invention may be applied to various types of hair treatments, the present invention is described herein in the context of hair dyeing treatments. Hair dyeing is a very popular cosmetic treatment. Currently, there are four basic types of hair color treatments classified according to color retention. Temporary and semi-permanent are non-oxidative treatments that use colored dyes deposited on the surface of the hair cuticle. Temporary hair dyeing is used to color hair for a short period, such as a day. This type of hair color can be achieved with basic dyes, acid dyes, disperse dyes, pigments, or metallized dyes. Temporary dyes, which cannot penetrate the hair due to their molecular size and low affinity for hair, are typically washed out in a single wash. In contrast, semi-permanent dye molecules are smaller and can exhibit some degree of affinity for hair. The smaller the size, the more the dye can penetrate the cuticle, and there is even a possibility that some of the dye will reach the cortex. Nevertheless, alkalizing agents are sometimes used in semi-permanent treatments to facilitate penetration through the cuticle. For this reason, the present invention can find applications in semi-permanent hair dyeing.
