Description

Powder hair decolorant composition {Powdery hair decolarant composition}

The present invention relates to a powdered hair decolorant composition. More specifically, the present invention relates to a powdery hair decolorizing agent composition containing silicone powder, which improves the fluidity of the powder and at the same time improves applicability when applying the hair, and improves the feel of the hair before and after rinsing after the decolorizing treatment of the hair. The powdered hair bleaching agent described in the present invention refers to an agent that brightens the hair by oxidizing the melanin pigment present in the hair.

In general, the hair bleaching agent is applied to the hair after mixing with a liquid oxidizing agent containing hydrogen peroxide in a predetermined ratio before use. Alkali agent is generally used as the main component of the hair decolorizing agent, and there is a liquid or klim type type that decomposes hydrogen peroxide by mixing with an oxidizing agent and making it into alkaline conditions. Powder type bleaching agent containing the mainstream. Liquid or cream type hair bleaching agents have a relatively weak reaction compared to powder type, and have a mild oxidative bleaching effect. On the other hand, the powder type bleaching agent containing a oxidizing agent (reactant) is very violent reaction, because the decolorization effect of melanin is very strong, it is used for the purpose of brightening black hair effectively.

The raw materials used in the typical powder type hair decolorizing agent are the above-mentioned oxidizing agents (peractants) of persulfate, perborate, percarbonate, peroxygenated ammonium, sodium ( so

dium and potassium salts are used. In addition, an amine alkali or metasilicate is used in the powder as an alkali to ensure a pH of 9.5 to 11.5 after mixing with the oxidant solution for proper oxygen generation.

In addition, hydroxyalkylated cellulose, carboxymethyl cellulose, and the like are used as thickeners to increase usability of the product. In addition, silica derivatives are used as desiccants in order to increase the shelf life at the time of product storage and to prevent decomposition of the product by moisture absorption.

Several drawbacks are pointed out for these powder type hair bleaching agents. First of all, there is a problem in manufacturing or product due to poor fluidity in terms of physical properties of the powder.After mixing powder decolorant and oxidizer solution, viscosity is formed by thickener to remove the inconvenience of flowing after applying to hair. It is pointed out that one does not spread well when applied to the hair, and the operability is not easy. In addition, since the surface of the hair is damaged by high alkali conditions and violent oxidation reactions, it is pointed out that the hair feel becomes bad before and after rinsing after the decolorizing treatment.

The present inventors have made intensive studies to improve the above problems, and as a result, the powdered hair decolorant composition containing silicon powder in a specific ratio not only improves the fluidity of the powder, but also after mixing the powder with the oxidant, The applicability and operability are improved and the present invention was completed by remarking the surprising fact that the hair texture is improved before and after rinsing after the decolorizing treatment.

The present invention provides a powdered hair comprising 0.01 to 20% by weight of one or two or more silicone powders selected from silicone rubber powder, silicone resin powder, silicone resin coating powder on the surface of silicone rubber powder and silicone hydrophobization treated silica powder. A decolorant composition.

Hereinafter, the present invention will be described in detail.

The silicone rubber powder used in the present invention preferably has a structure of a cross-linked linear dimethylpolysiloxane, and is preferably a white spherical powder having a particle size distribution of 1 to 30 µm. As a polymer having a structure crosslinked with a dimensional network structure, a white spherical powder having a particle size distribution of 0.2 to 8 μm is preferable. The silicon composite powder coats the surface of the silicone rubber powder with a silicone resin and has a particle size distribution of 1 It is preferable that it is a spherical powder phase of ˜30 μm, and as hydrophobized silica powder, it is preferable that the surface of silica is hydrophobized with silicon and the particle size distribution is 0.5 to 20 μm.

Since the above-described silicon powder has a siloxane structure in dimethyl polysiloxane which is conventional liquid silicone, it has properties similar to those of dimethyl polysiloxane which is conventional liquid silicone. However, blending ordinary liquid silicone with powdered hair bleaching agent facilitates hair application and manipulation after mixing with oxidizing agent and improves the hair feel after bleaching treatment, but gives undesired results to powder formulation itself, thus achieving the desired purpose. Can't.

The powdered hair decolorant composition according to the present invention may be used by mixing one or two or more kinds of the above silicone powder, and the blending amount is preferably 0.01 to 20.0 parts by weight when the total amount of the powdered hair decolorant composition is 100 parts by weight. When the silicon powder is used in an amount of 0.01 parts by weight or less, a sufficient fluidity improvement cannot be expected, and when 20 parts by weight or more is used, no further fluidity increase can be expected due to an increase in the amount used.

The powdery hair decolorant composition according to the present invention may further contain the following components together with the silicone powder.

① Oxidation accelerator: Water-soluble salt of persulfate, percarbonate, perborate.

Ex) sodium persulfate, potassium persulfate, etc.

② Alkaline:

Ex) ammonium persulfate, sodium silicate

③ Thickener: hydroxyethyl cellulose, carboxymethyl cellulose Na, etc.

④ Hair protection agent: polymer, protein

⑤ Softener: EDTA.2Na, etc.

⑥ Colorant: Ultramarine, Viloet-401, etc.

⑦ Others: Spices, conditioning agents, etc. are used.
