preparation example Construction

[0036] The present invention provides the preparation method of No. 2 low-expansion hair dye described in the technical solution, comprising the following steps:

[0037] Water, sodium fatty alcohol sulfate and a humectant are first mixed to obtain a water phase material;

[0038] The fatty alcohol polyoxyethylene ether, the thickener and the oleyl alcohol are mixed for the second time to obtain the oil phase material;

[0039] mixing the water-phase material and the oil-phase material to emulsify to obtain an emulsified material;

[0040] The emulsified material is mixed with sodium stannate trihydrate, etidylic acid, hydrogen peroxide and essence for the third time to obtain No. 2 low-swelling hair dye.

[0041] In the invention, water, sodium fatty alcohol sulfate and humectant are first mixed to obtain water phase materials. In the present invention, the first mixing is preferably carried out in a water phase pot, and the present invention has no special limitation on th...

Embodiment 1

[0047] Low expansion hair dye No. 2 components:

[0048] Water 89.47%, Sodium Laureth Sulfate 0.1%, Propylene Glycol 0.5%, Cetearyl Alcohol 2.5%, Ceteth-250.5%, Oleyl Alcohol 0.5%, Sodium Stannate Trihydrate 0.03%, Edithionate 0.2%, hydrogen peroxide 6.0%, essence 0.2%.

[0049] Preparation:

[0050] Put water, sodium lauryl sulfate and propylene glycol into the water phase pot, heat to 85°C, stir and dissolve to obtain the water phase material; add cetearyl alcohol, ceteth-25 and oil into the oil phase pot Alcohol, heated to 85°C, stirred and dissolved to obtain the oil phase material; then put the water phase material and the oil phase material into the emulsification pot respectively for emulsification, stirred (35r / min) for 10 minutes, cooled, stirred and cooled to 50°C At the same time, dissolve sodium stannate trihydrate with a small amount of water and put it into an emulsification pot, then add etidyl phosphoric acid, hydrogen peroxide and essence, and stir evenly to...

Embodiment 2

[0056] Low expansion hair dye No. 2 components:

[0057] Water 85.2%, Sodium Laureth Sulfate 0.15%, Propylene Glycol 1.0%, Cetearyl Alcohol 3.0%, Ceteth-250.6%, Oleyl Alcohol 0.6%, Sodium Stannate Trihydrate 0.05%, Edithionate 0.2%, hydrogen peroxide 9.0%, fragrance 0.2%.

[0058] Preparation method: according to the method of Example 1, the No. 2 low-expansion hair dye was prepared.

[0059] Stability test: The stability test was carried out according to the method of Example 1, and the results are shown in Table 2.

[0060] The stability data of the low expansion hair dye No. 2 agent of table 2 embodiment 2

[0061] Recording time / h 24 48 72 96 120 144 168 192 Pressure number / MPa 0.025 0.025 0.025 0.025 0.025 0.025 0.025 0.025

[0062] It can be seen from Table 2 that when the No. 2 low-expansion hair dye of Example 2 is placed in a thermostat at 40°C, the pressure in the bottle does not increase, indicating that the hydrogen peroxide is ...

Abstract

The invention provides a low-expansion hair dye No.2 agent and a preparation method thereof, and belongs to the technical field of hair dyes. According to the invention, sodium fatty alcohol sulfate and sodium fatty alcohol polyoxyethylene ether are used as an emulsifier combination, sodium stannate trihydrate and hydroxyethyl diphosphate are used as a heavy metal chelating agent combination, wherein the sodium fatty alcohol polyoxyethylene ether and the sodium fatty alcohol sulfate of the the emulsifier combination can be prepared into stable cream and can also have good compatibility with the sodium stannate trihydrate and the hydroxyethyl diphosphate of the heavy metal chelating agent combination, so that the color of the product is not changed, and the product is not thinned in a layered manner. Through dual combination of the emulsifier combination and the heavy metal chelating agent combination, the influence of heavy metal iron ions and copper ions on the stability of hydrogen peroxide is solved, and the compatibility of heavy metal chelating agents and emulsifiers is also solved, so that the hair dye No.2 agent product does not expand any more, and the effect of the hair dye No.2 agent product is ensured.

Description

technical field [0001] The invention relates to the technical field of hair dyes, in particular to No. 2 low-expansion hair dye and a preparation method thereof. Background technique [0002] At present, the No. 2 hair dye (also known as dioxyemulsion or color developer) sold on the market is affected by surfactants and heavy metals in formula components during transportation and storage, causing hydrogen peroxide to decompose and release oxygen, making The air pressure in the airtight packaging container increases, causing the container to expand or even burst, and reduces the effective components of hydrogen peroxide, affecting the dyeing effect. [0003] The traditional technology only pays attention to the influence of metal iron ions and pH value on the stability of hydrogen peroxide, but ignores the influence of metal copper ions on the stability of hydrogen peroxide, and the compatibility of heavy metal chelating agents and emulsifiers is different, improper use will ...
