DETAILED DESCRIPTION

(5) Hereinafter, preferred embodiments of the invention will be described in more detail with reference to the accompanying drawings.

(6) The hair-dyeing composition according to one embodiment of the present invention contains a dyeing gent; and an oxidizing agent, wherein the dyeing agent having an alkalizing agent selected from the group of 2-Dimethylamino-2-methylpropanol, aminomethyl propanol and dimethylamino methylpropanol, or its mixtures, from about 0.5 to about 7 percent by weight based on the total weight of the dyeing agent; an antioxidant from about 0.1 to about 5 percent; a reducing agent from about 0.1 to about 5 percent by weight; a base and a coupling from about 0.01 to about 5 percent by weight; and a solvent as the remainder. The oxidizing agent having a hydrogen peroxide from about 1 to about 20 percent by weight based on the total weight of the oxidizing agent; an emollient from about 1 to about 10 percent by weight; an emulsifying agent from about 0.01 to about 5 percent by weight based on the total weight of the oxidizing agent and a solvent as the remainder.

(7) The present inventors have studied compositions that are capable of decreasing the irritating odor, especially the ammonia odor, generated when using an oxidative hair-dyeing composition and confirmed that using an amino propanol as an alkalizing agent, such as a dimethylamino methylpropanol, instead of ammonium hydroxide as the main alkalizer, the composition is capable of achieving achieve excellent color coverage while having diminute amounts of ammonium hydroxide and, consequently, without the malodor of ammonium hydroxide and its harmful effects to the scalp. As a result of studies on various compositions, the present inventors have confirmed that the ammonium hydroxide is decreased when the alkalizing agent, preferably a dimethylamino methylpropanol, is used and excellent hair color coverage is achieved, which is equivalent to an alkalinizing agent ammonium hydroxide, thereby completing the present invention.

(8) In detail, a composition using an alkalizing agent such as ammonium hydroxide provides good alkalization, delivers good color coverage but mostly undesired malodor and damage to the scalp and hair. In view of the good color coverage, the alkalizing agent of conventional hair-dyeing compositions is ammonium hydroxide, which volatilizes and causes an irritating odor and adversely affect the bodies of the practitioner and the customer during the procedure of dyeing.

(9) Accordingly, it is a general desire to achieve good color coverage whilst preventing the malodor, and various reducing agents have been researched. As a result, it has been confirmed that the substituting varying amounts of the ammonium hydroxide for an amino propanol prevented the hair-dyeing composition to have the characteristic malodor whilst achieving equivalent results of color coverage.

(10) It has been confirmed that an alkalizing agent as an amino propanol, preferably selected from the group of 2-Dimethylamino-2-methylpropanol, aminomethyl propanol and dimethylamino methylpropanol, or its mixtures, from about 0.5 to about 7 percent by weight based on the total weight of the dyeing agent, are suitable as an alkalizing agent that delivers good color coverage. FIG. 1 is a black and white negative photograph illustrating an untreated, natural hair tress having 30% of gray hair. FIG. 2 is a black and white negative photograph illustrating a hair tress having 30% of gray hair treated with a composition of the present invention. FIG. 3 is a black and white negative photograph illustrating a hair tress having 30% of gray hair treated with an ammonium hydroxide composition as a Comparative Formulation. Comparison by visual inspection of the hair tress treated with the hair-dyeing composition of the present invention (FIG. 2) with the hair tress treated with an ammonium hydroxide composition (FIG. 3) illustrates the similar color coverage of both compositions. The present invention delivers equivalent color coverage of an ammonium hydroxide-based composition, without its drawbacks, such as malodor and scalp irritation and health issues.

(11) To complete de hair-dyeing composition, the dyeing agent may contain an emulsifying agent, preferably selected from Ceteareth-20, dicetyl phosphate, Laureth-8, lauryl alcohol, oleic acid or its mixtures. It may further contain an emulsifying agent in an amount of from about 0.01 to about 5 percent by weight based on the total weight of the dyeing agent.

(12) The base and coupling in the dyeing agent may be selected from the group consisting of phenylenediamine, such as toluene-2,5-diamine sulfate, 2,4-diaminophenoxyethanol hydrochloride, aminophenols, such as m-aminophenol, naphtols, pirazolones, resorcinol, and a mixture thereof, but these are exemplary of the present invention, and the invention is not intended to be limited thereto. The base and coupling are preferably contained in an amount of from about 0.01 to about 5 percent by weight based on the total weight of the dyeing agent, but when the content is out of the above range, there may be a problem that proper color development is not achieved.

(13) The dyeing agent may further contain a hair conditioning from about 2 to about 6 percent by weight based on the total weight of the dyeing agent, and the hair conditioning may be Peg-2 Dimeadowfoamamidoethylmonium Methosulfate, lauryl alcohol or a mixture thereof.

(14) In the dyeing agent, the solvent may be water. Alternatively, the solvent may be ethanol, laureth, glycerin.

(15) The dyeing agent may further contain from about 4 to about 50 percent by weight of an emollient agent selected from the group cetearyl alcohol, dicaprylyl ether, glyceryl stearate, oleic acid, oleyl alcohol, pentaerythrityl tetraisostearate, and mixtures thereof. The solvent of the oxidizing agent may be the same and/or similar to the solvent of the dyeing agent.

(16) The oxidizing agent is an oxidizing active hydrogen peroxide, preferably from about 1 to about 20 percent by weight based on the total weight of the oxidizing agent. The emollient of the oxidizing agent is preferably from about 1 to about 10 percent and an emulsifying agent is also desired, from about 0.01 to about 5 percent by weight based on the total weight of the oxidizing agent.

(17) The dyeing agent, the oxidizing agent, or both, may further contain a first additive selected from the group consisting of an antioxidant, a sequestering agent, a perfume, and a mixture thereof. The dyeing agent, the oxidizing agent, or both, may further contain a second additive selected from the group consisting of a hair softening agent, a conditioning agent, a hair polishing agent, and a mixture thereof. They may further contain a third additive selected from the group consisting of a sequestering agent, a perfume, and a mixture thereof.
