[0124] Ethanolamine: 4.5%; Sodium sulfite: 0.6%;

[0125] Acrylates and steareth-20 and methacrylate copolymer: 3.5%;

[0126] Sodium EDTA2: 0.3%; Oleyl ether-5: 3.0%;

[0127] Propylene Glycol: 3.5%; PEG-12 Dimethicone: 1.5%;

[0128] PEG-75 lanolin: 1.5%; essence: 0.6%;

[0129] Shouwu extract: 1%;

[0130] The content of the dye mixture is: 3%;

[0131] Water: 77%.

[0132]

[0133] The ratio of component B is:

[0134] Hydrogen peroxide: 12.0%; 16-18 alcohol: 0.2%;

[0135] Oleyl ether-5: 2.0%; Phosphoric acid: adjust the pH value...

Embodiment 2

[0138] In the present embodiment, there is no ammonia and no p-phenylenediamine hair dye:

[0139] The carrier substance components are:

[0140] Ethanolamine: 2%; Sodium sulfite: 2.5%;

[0141] Acrylates and steareth-20 and methacrylate copolymer: 15%;

[0142] Sodium EDTA2: 0.5%; Oleyl ether-5: 5%;

[0143] Propylene Glycol: 3%; PEG-12 Dimethicone: 4%;

[0144] PEG-75 lanolin: 1%; essence: 0.5%;

[0145] Shouwu extract: 0%;

[0146] The content of the dye mixture is: 6%;

[0147] Water: 60.5%.

[0148]

[0149] The ratio of component B is:

[0150] Hydrogen peroxide: 3%; 16-18 alcohol: 8%;

[0151] Oleyl ether-5: 4%; Phosphoric acid: adjust the pH value to 3;

[0152] Water: 85%.

[0153]

Embodiment 3

[0155] In the present embodiment, there is no ammonia and no p-phenylenediamine hair dye:

[0156] The carrier substance components are:

[0157] Ethanolamine: 10%; Sodium sulfite: 0.5%;

[0158] Acrylates and steareth-20 and methacrylate copolymer: 3%;

[0159] Sodium EDTA2: 0.8%; Oleyl ether-5: 1%;

[0160] Propylene Glycol: 10%; PEG-12 Dimethicone: 0%;

[0161] PEG-75 lanolin: 5%; essence: 0.8%;

[0162] Shouwu extract: 2.5%;

[0163] The content of the dye mixture is: 0.5%;

[0164] Water: 65.9%.

[0165]

[0166] The ratio of component B is:

[0167] Hydrogen peroxide: 7%; 16-18 alcohol: 5%;

[0168] Oleyl ether-5: 0%; Phosphoric acid: adjust the pH value to 3;

[0169] Water: 88%.

Abstract

The invention relates to an ammonia-free and ursol-free hair dye and a preparation method thereof. The hair dye consists of a component A and a component B, wherein the component A consists of dye mixture, alkanolamine substance, water-soluble inorganic salt, acrylate copolymer and derivants thereof or fatty alcohol, acid and fat and derivants thereof, heavy metal chelate, surfactant, alcohol substance, dimethyl silicone oil, lanolin, essence and plant extract; and the component B consists of hydrogen peroxide, fatty alcohol, acid and fat and derivants thereof, surfactant, viscosity and gel appearance modifier and phosphoric acid. The hair dye is prepared by a specific method, has no ursol which is easy to cause skin sensibility and no ammonia water which has stimulation to respiratory tract and has the characteristics of no toxicity, no pungent smell, convenient use and good effect.

Description

technical field [0001] The invention relates to a two-component oxidative hair dye and a preparation method thereof, in particular to a two-component oxidative hair dye without ammonia water and p-phenylenediamine and a preparation method thereof. [0002] Background technique [0003] Most oxidative hair dye formulations currently on the market contain p-phenylenediamine and ammonia, or at least one of them. And in order to pursue the hair dyeing effect, the content of these harmful substances in the formula is relatively high, so there is a serious potential safety hazard to the human body. The current common hair dyes are likely to cause the following hazards to hair dyers: [0004] Skin allergic reaction: Allergy is the most common harmful symptom of hair dye. Slight itching of the scalp, swelling of the nasal cavity and eyes, skin ulceration, redness, swelling and eczema, etc. Severe cases can cause asthma, rhinitis, chronic bronchitis and so on. [0005] Induce va...
