Description

Bleaching agent for hair and preparation process thereof

Technical Field

The invention belongs to the technical field of cosmetics, and particularly relates to a hair bleaching agent and a preparation process thereof.

Background

For Asian consumer groups with black or dark brown hair color mostly, in order to change own hair color into bright and bright hair color, the dark hair color must be bleached to be light, and then own hair must be dyed with bright color by products such as a bleaching agent for hair.

The purpose of the product is to perform base color bleaching and depth bleaching on hair. The hair lightening agents used on the market are mostly in the form of a mixture of two agents. Wherein 1 agent is powder, and the core components are color developing agent and alkaline component. The 2 doses are generally called the hydrogen peroxide milk in the market, and the character of the hydrogen peroxide milk is milky white paste. By mixing the two agents, the color developing agent with strong oxidizing property reacts to achieve the aim of lightening hair. But the powder 1 has dust raising phenomenon, so that the stirring and the using process are inconvenient. Secondly, 1 dose has a problem of poor conditioning properties.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below, and it is apparent that the described embodiments are a part of the embodiments of the present invention, but not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention aims to solve the problem that the powder bleaching agent is inconvenient to use, and as a double-agent mixed type hair bleaching agent, after the double agents are uniformly mixed, a viscous paste mixture is formed, and then the mixture is uniformly coated on hair by using tools such as a comb and the like, so that the aim of convenient use is fulfilled.

Peroxides have been used in a number of fields as commonly used bleaching agents. However, in hair products, the limited amount of peroxide required results in a limited ability to lighten hair with the hydrogen peroxide based product, and in most cases, the use of peroxide alone does not meet the need to lighten hair. The persulfate has strong oxidizing property, and is subjected to reduction reaction under the condition of proper pH by mixing the two agents, so that the hair is bleached.

The product 1 comprises the following components in percentage by weight: 0.5-30% of alkaline component, 0.5-20% of thickening agent, 25-45% of color developing agent and 0.5-5% of hair conditioning agent. The alkaline component is one or more selected from ammonium hydroxide, monoethanolamine, triethanolamine, sodium hydroxide, sodium silicate and sodium metasilicate. When a plurality of sodium hydroxide, sodium silicate and sodium metasilicate are simultaneously selected, any proportion can be carried out as long as the final pH range is about 10-11; the thickening agent is one or more selected from cetearyl alcohol, hydrogenated (styrene/isoprene) copolymer, hydrogenated (styrene/butadiene) copolymer, butylene/ethylene/styrene copolymer, hydroxyethyl cellulose, carboxymethyl cellulose, hydroxypropyl cellulose, silica and corn starch; the hair conditioner is one or more selected from stearyltrimethyl ammonium chloride, polyquaternium-10, polyquaternium-6 and xanthan gum; the conditioning agent is used for caring hair. The selected color developing agent is one or more of potassium peroxydisulfate, ammonium persulfate and sodium peroxydisulfate.

The 1 dose of the product also comprises 0.01 to 20 percent of filling agent. The purpose of adding the filler is to increase the whole volume of the bleaching agent and ensure that the bleaching agent forms cream characters. The bulking agent is generally selected to be an oily ingredient to avoid inactivation of the main ingredient. The filler is one or more selected from mineral oil and vaseline.

The agent 2 of the product mainly comprises a thickening agent, a color developing agent, an acidic component, a chelating agent and the like. The acidic component is one or more selected from phosphoric acid and hydroxyethyldiphosphonic acid; the thickening agent is one or more selected from stearyl alcohol, cetearyl alcohol, ceteareth-25, ceteareth-20 and monoglyceride; the color developing agent is peroxide; the chelating agent is one or more selected from disodium EDTA, sodium sneezate and tetrasodium EDTA.

The product is prepared into uniform paste by 1 dose of powder with bleaching capability through a thickening agent. The use of the hydrogenated (styrene/butadiene) copolymer and the hydrogenated (styrene/isoprene) copolymer can effectively thicken the oily filler, ensure the uniformity of powder in the paste and avoid the layering phenomenon.

The product is also added with a certain amount of hair conditioning components with conditioning property, so as to achieve the effect of conditioning while bleaching hair. Cationic cellulose is commonly used in hair care products, and the addition amount of the cationic cellulose is about 0.2-0.5%, so that the cationic cellulose has a certain antistatic effect and makes hair soft and smooth.

The product has stable quality and no problem in high and low temperature storage. The components do not react with other components, and have long shelf life. The product has no harm to the health of users. During the use process of the product, consumers can properly adjust the use time to bleach the hair to a proper color.
