Description

High-smoothness easy-carding type silicon-free hair conditioner and preparation method thereof

Technical Field

The application belongs to the field of daily chemical products, and particularly relates to a high-smoothness and easy-carding type silicon-free hair conditioner and a preparation method thereof.

Background

With the improvement of the living standard of people, the number and frequency of people for perming and dyeing hair are gradually increased, and the influence of factors such as environmental pollution is added, so that the problems of dry hair, frizziness, difficult carding and the like caused by damaged hair quality and damaged hair scales are brought, and the hair is more hydrophilic. The hair conditioner is an emulsifying system containing hair-moistening grease and a cationic conditioning agent, can be effectively spread on the surface of hair without being washed away by water in the use process, can effectively smooth the hair scales tilted on the surface of the hair, and meanwhile reduces the negative charge intensity of the surface of the hair, so that the surface of the hair is smooth and flexible, and the hydrophobic protective film can effectively prevent the water in the hair from being lost and can effectively keep the moisture content in the hair stable.

At present, a series of silicone oil components such as polydimethylsiloxane and the like are mainly added into a hair conditioner product in the market to fill damaged parts of hair scales, so that the comb property of hair is improved. All silicone emulsions reduce the average combing force of the hair by at least as much as 70%. The anionic emulsion of dimethiconol (and) triethanolamine salts of dodecylbenzenesulfonic acid has a stronger adhesion to eastern hair or bleached blond hair than the nonionic emulsion with polydimethylsiloxane as the internal phase. However, this emulsion reduces the comb force by 80% when the hair is treated with a nonionic emulsion of dimethyl silicone.

Because silicone oil adheres to hair in a manner that fills up the hair scales that open up and are damaged, people are concerned that it also deposits on the scalp and blocks pores, causing adverse effects such as redness, inflammation, acne, hair loss, etc. The silicone oil adheres to the hair to thicken the hair and increase the weight, and simultaneously reduce static electricity between the hairs, so that the hair is not fluffy or even flat after being dried. Silicon-free hair conditioners remain the subject of research and market development based on consumer experience and cost considerations.

Disclosure of Invention

The application aims to solve the problems of the existing silicon-containing hair conditioner and provides a high-smoothness and easy-carding type silicon-free hair conditioner and a preparation method thereof.

According to the application, the cationic conditioner is added in the formula, the specific proportion of the conditioner ester quaternary ammonium salt and the alkyl quaternary ammonium salt is selected, and no silicone oil is added, so that the dry comb experience is better while the hair wet comb effect is improved, the dry comb effect of the conventional silicon-containing hair conditioner is achieved, the silicon-free hair conditioner with better high conditioning comb property is prepared, and the thought is provided for the preparation of the silicon-free hair conditioner.

The aim of the application can be achieved by the following scheme:

the application provides a high-smoothness easy-carding type silicon-free hair conditioner, which comprises the following components in parts by weight in every 100 parts of silicon-free hair conditioner:

as one embodiment of the present application, the cationic conditioning agent includes an esterquat and an alkyl quat. The dosage ratio of the esterquat to the alkyl quat is 1-6:3. the amount of the esterquat is preferably 0.6 to 1.6 parts.

As one embodiment of the present application, the esterquat comprises behenyl trimethyl ammonium methyl sulfate; the alkyl quaternary ammonium salt comprises one or more of cetyl trimethyl ammonium chloride, stearyl trimethyl ammonium chloride and behenyl trimethyl ammonium chloride.

The ester quaternary ammonium salt (behenyl trimethyl ammonium methyl sulfate) contains ester groups, so that the hydrophobicity of the hydrophobic groups is reduced, and the ester quaternary ammonium salt has stronger hydrophilicity. In addition, ammonium methyl sulfate is more hydrophilic than ammonium chloride, and is used as a conditioner, because the hydrophilic group of the ammonium methyl sulfate can be adsorbed on the hair surface through electrostatic adsorption, the hydrophobic group is far away from the hair surface, and the hydrophobic group is arranged on the whole hair surface in an oriented way to form a protective film, thereby reducing the electrostatic charge of the hair, and because the ammonium methyl sulfate has good affinity with scalp, the ammonium methyl sulfate has smaller irritation to scalp.

Two of the most common hair conditioning agents are behenyl trimethyl ammonium chloride and cetyl trimethyl ammonium chloride. Although both materials have good conditioning properties, the European Union has limited use in some cleaning products, and if the materials are in contact with the skin, they are irritating and/or toxic and have a long-lasting effect. The longer the alkyl chain length, the greater the number, the better the disentanglement, and the easier it is to be adsorbed on the hair. The high carbon chains (C22, C36) can be relatively highly adsorbed onto the hair and, if used too much, can exhibit a tendency to deposit or overcocondition. Therefore, we select the high-low carbon chain alkyl/ester quaternary ammonium salt to compound to solve the problem. The application adopts the complex use of the esterquat and the alkyl quat, the proportion of the esterquat and the alkyl quat is in a proper range, the neutralization of the positive charges carried by the hair and the negative charges carried by the hair can not be satisfied when the neutralization of the negative charges is too little or too much, and the esterquat and the alkyl quat are accumulated on the hair after being dried due to too much, so that the combing work is increased. The complexing ratio affects its charge neutralization effect on the hair strand.

As an embodiment of the present application, the chelating agent comprises disodium EDTA and/or tetrasodium EDTA.

As an embodiment of the application, the emulsifier comprises cetostearyl alcohol and/or stearyl alcohol.

As one embodiment of the application, the preservative is selected from one or more of kathon, phenoxyethanol and sodium benzoate.

The application provides a preparation method of a high-smoothness easy-carding type silicon-free hair conditioner, which comprises the following steps:

s1, mixing a cationic conditioning agent, a chelating agent and distilled water at a first temperature to obtain a first reaction mixture, and mixing for a first preset time;

s2, mixing the first reaction mixture and the emulsifying agent dissolved by heating at a first temperature, and heating to a second temperature to obtain a second reaction mixture;

s3, emulsifying the second reaction mixture in an emulsifying device for a second preset time, and then cooling;

and S4, when the temperature of the second reaction mixture is reduced to a third temperature, mixing the second reaction mixture, the preservative and the essence to obtain a third reaction mixture, and discharging to obtain the high-smoothness and easy-carding type silicon-free hair conditioner.

As an embodiment of the present application, the first temperature in step S1 is 85 to 90 ℃; the first predetermined time is 10-20 minutes.

As an embodiment of the present application, the second temperature in step S2 is 90 to 100 ℃.

As an embodiment of the present application, the second predetermined time in step S3 is 15 to 45 minutes.

As an embodiment of the present application, the third temperature in step S4 is 45-50 ℃.

Compared with the prior art, the application has the following beneficial effects:

(1) The silicon-free hair conditioner with high smoothness and easy carding is prepared by adding the cationic conditioner into the formula and further optimizing the content range of each component, and a better dry and wet carding effect is obtained in a severe damaged hair bundle test.

(2) The product can effectively solve the problem that hair is tangled and difficult to comb caused by hair damage due to external factors such as hot dyeing, can provide dry and wet comb properties comparable to those of silicon-containing hair conditioners in the market, and can avoid the trouble that consumers damage the scalp caused by silicon oil due to the addition of the silicon oil.

(3) The product prepared by the method has simple preparation process and low production cost, can reduce the use of silicone oil in the product, and can provide a new thought for the development of the silicon-free hair conditioner.

TABLE one EXAMPLES 1 to 5

The testing method comprises the following steps: cleaning the new hair bundles severely damaged in Asia with clear water, performing wet comb test, defining test results as wet comb blank data, grouping the hair bundles according to the data, wherein each three hair bundles with the data being closer are grouped; after naturally airing overnight, testing the corresponding dry comb combing work, and defining dry comb blank data. The final data for each example and comparative example is the average of three hair bundles. The test conditions are that the temperature between constant temperature and constant humidity is 20 ℃ and the humidity is 50%.

Wet combing test: wetting the hair bundle, weighing 2g of hair conditioner, uniformly smearing the hair bundle on the hair bundle, staying for 2min, washing for 30s by using clear water (water temperature is 35 ℃), testing by using a Dia-Stron MTT175 instrument, slightly dipping the hair bundle into a beaker (water temperature is 35 ℃) for three times, slightly pressing off redundant water drops in the hair bundle from beginning to end by using two fingers, and weighing to ensure that the water retained each time is similar. And (3) each bundle of hair is circularly tested for 20 times, after each test, the hair is taken off from the test clamp, the bundle of hair is dipped into the beaker lightly and washed three times, then redundant water drops in the bundle of hair are pressed off lightly from the beginning to the end by two fingers, a second test is carried out, and the like.

Dry combing test: the hair bundles are hung in a constant temperature and humidity laboratory for overnight natural airing. The hair bundles are combed three times from the head to the tail by using an anti-static comb, and are placed on a clamp for testing. Twenty times per bundle of hair, after each test, the hair was combed several times with a comb for a second test, and so on, in order to remove static electricity in the hair.

And (3) data selection: data relative standard deviation = (standard deviation/mean) 100, data set with relative standard deviation <25% was selected.

Carding work change rate = (blank hair bundle carding work-after-use hair conditioner carding work)/blank hair bundle carding work

Conclusion: the high smooth easy-carding type silicon-free hair conditioner has good dry and wet combing performance, the examples have good wet combing effect, and the dry combing effect of the example 1 is best when the ratio of the esterquat to the alkyl quat is 1:2. The overall combing is better than that of commercially available silicon-containing hair conditioners. The wet comb combing property is higher than that of the commercially available silicon-free hair conditioner, and meanwhile, the wet comb combing property is better than that of the commercially available silicon-free hair conditioner, so that the silicon-free hair conditioner has better conditioning performance, and a large amount of silicone oil in the hair conditioner can be effectively reduced or avoided.
