Technical Field

The invention belongs to the field of daily chemical products, and particularly relates to a hair care composition with a multiple-effect repairing effect and application thereof.

Background

With the improvement of living standard of residents, the hair perming and dyeing are increasingly popular, and the factors such as environment and pressure are added, so that the hair roots and the hair of people are generally malnourished, and then the hair is gradually thinned, dried and even crisp and falls off. And as the length of hair increases, the hair scale cells are partially shed, and the hair is less flexible and is easy to twist, so that the hair is extremely easy to knot and break during combing and washing. Hair care products are therefore one of the necessities of modern households.

The hair conditioner is a hair care product for caring hair, and has the effects of tightening and smoothing hair scales, moistening hair, and enabling the hair surface to be soft, soft and glossy. It can be used after washing hair. Hair conditioners are typically white or translucent, transparent emulsions or creams. The hair care product mainly comprises cationic surfactant, quaternary ammonium salt, grease and other main components. The hair conditioner belongs to light oil hair care cosmetics, is not easy to wash away by water in the use process, and can well smooth and shiny hair. However, the existing hair conditioner can only be used for softening the hair tips, and even if the hair conditioner has a repairing effect, the hair can not be effectively prevented from being fragile and easy to break.

Aiming at the problem, the invention provides a multi-effect repairing hair conditioner and a preparation method thereof, and the hair can be endowed with more nutrition and stronger and glossy by using hydrolyzed protein and microalgae oil. Can improve hair texture and facilitate combing. Can make hair smoother.

The invention also provides application of the hair care composition in hair care products.

Hair is a network of long-chain polymers of amino acid polypeptides, keratin proteins, whose major constituent is keratin, accounting for about 97%. Keratin consists of a wide variety of amino acids, with the highest cystine content, typically up to 14% or more. The cortex consists of a complex composite structure with crystallin structures embedded in an amorphous, non-helical protein matrix. At the molecular level, the crystal fraction is composed of alpha-helical protein dimers (coiled coil structure), and 8 such dimer protein constituent microfibers (keratin intermediate filaments (KIFs)) are embedded in amorphous proteins, i.e., keratin-associated proteins (KAPs), to form large fibers. Keratin-associated proteins (KAPs) are sulfur-rich proteins that contain a large number of disulfide bonds, contributing to the mechanical and chemical resistance of human hair, and this complex structure imparts very good mechanical properties to human hair. The cortex determines various physical properties of the hair fiber, such as color, curl pattern, thickness and toughness. Therefore, various amino acids, polypeptides and proteins have certain conditioning effect on hair, and protein products are also additives of excellent hair nutrition and repair products. However, various amino acids, polypeptides and proteins cannot be well adsorbed on the surface of hair and scalp in the process of washing hair, and are not easy to absorb.

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

1. the invention uses hydrolyzed wheat protein, the main component of which is various amino acids, which is one of the essential nutritional components of human body. It has low molecular weight, and has a molecular weight of about 1800 daltons, and can promote hair growth, improve hair structure, and cover hair surface more easily than penetration to form a protective layer for repairing damaged hair. The hydrolyzed wheat protein with low molecular weight can penetrate into cortex after penetrating the hair scale. When the hydrolyzed wheat protein permeates into cortex, hair injury can be relieved, and hair is repaired by protein recombination.

2. The microalgae oil used in the invention is a highly stable bio-based oil which is rich in more than 90% of Omega-9 unsaturated fatty acids (oleic acid) beneficial to the human body. Oleic acid is a main component of natural free fatty acid on hair, but oleic acid is unstable, oleic acid contains double bonds, can generate autoxidation when being placed in air for a long time, has spoiled harshness and is easy to deteriorate, and microalgae oil is not easy to deteriorate, so that the hair-care agent can help to maintain scalp percutaneous moisture loss and increase hydration, enhance repair reaction, increase glossiness of hair and the like.

3. The invention can form a stable layer of nutrient substance protection film on the surface of hair by compounding and combining microalgae oil and hydrolyzed wheat protein, and can firmly lock nutrient substances on hair while preventing water loss.

4. As the microalgae oil contains more than 90% of oleic acid, the hydrolyzed wheat protein can be accelerated to permeate into cortex, so that the hydrolyzed wheat protein can be more remained on hair, hair injury is repaired from inside to outside, more nutrition is given to hair, and the hair is stronger and glossy. The loss of hydrolyzed wheat protein during use is effectively avoided, and the hydrolyzed wheat protein cannot be efficiently absorbed by hair. The microalgae oil and the hydrolyzed wheat protein can synergistically act to improve the hair texture, become easier to comb and enable the hair to be smoother.

Tensile Property test

Test purpose:

the effects of preventing hair breakage and strengthening hair can be achieved by repairing hair, so that the strength and toughness of the hair can be evaluated by stretching a single hair.

The testing method comprises the following steps:

the tress of human hair was rinsed with 2g of a 5% aqueous AES solution and excess water was gently pressed off with a soft clean tissue towel, soaking the tress in the prepared sample. After 24 hours, the hair bundles are taken out, washed clean under constant temperature and constant speed water flow, pressed by soft clean face tissues to remove surface moisture, and then placed in the environment of constant temperature and constant humidity [ (26+/-2) DEGC, (60+/-10)% RH ] for natural airing for 24 hours.

About 100 hair strands were cut from the root of the hair bundle, the diameter of each hair strand was measured using a digital outside micrometer and recorded, and 20 hair strands were selected therefrom so that the difference in diameter was not more than 5 μm. These 20 hairs were prepared as tensile samples and a single hair tensile test was performed using instrument MTT 175.

Tensile strength = tensile force/cross-sectional area (diameter)

Comparing examples 1,2 and 3 and comparative examples 2,3,4 and 5 with comparative example 1 respectively, analyzing the test data by using SPSS software, and if the data are normally distributed, carrying out data analysis statistics by adopting a t-test method or a variance analysis method; and if the data are in non-normal distribution, counting by adopting a rank sum test method.

The statistical methods all use a two-tailed test, if P <0.05, the hairline is significantly improved, indicating that the sample has the ability to improve the toughness of the hairline (if P <0.01, there is a very significant difference). If P >0.05, the hairline is not significantly improved, indicating that the sample does not improve the strength and toughness of the hairline.

Sensory testing:

after the hair was washed with a standard shampoo, 80 testers were selected, and the hair conditioners of examples and comparative examples were randomly divided into 8 groups, and the wet hair smoothness, combability, and dry hair smoothness and combability of the hair conditioner were scored (1 score to 5 score) by an expert group, and an average value was taken.

TABLE 1 tensile Property test data

		Example 1	18.34
Example 2	18.58
		Example 3	18.83
Comparative example 1	15.12
		Comparative example 2	17.26
Comparative example 3	17.18
		Comparative example 4	17.20
Comparative example 5	17.11

TABLE 2T test P value

T test	P value
		Example 1VS comparative example 1	0.002
Example 2VS comparative example 1	0.000
		Example 3VS comparative example 1	0.001

		Comparative example 3VS comparative example 1	0.026
Comparative example 4VS comparative example 1	0.01
		Comparative example 5VS comparative example 1	0.030

From table 1, table 2, example 1, example 2, example 3, and comparative example 2 all differed very significantly from comparative example 1, indicating that these 4 samples were very significant in improving the tenacious ability of hair and the repair effect was evident. Comparative example 3 also had a remarkable effect of improving the strength and toughness of the hair, and also had a slightly weaker repair effect than the other 4 samples. In 3 examples using microalgae oil and hydrolyzed wheat protein, the tensile strength is respectively improved by 21.30%, 22.88% and 24.54% compared with comparative example 1; compared with comparative example 1, the tensile strength of comparative example 2 using microalgae oil and silk peptide liquid is improved by 14.15%; comparative example 3, which used jojoba oil and hydrolyzed wheat protein, had a tensile strength increase of 13.62% compared to comparative example 1; comparative example 4, which used microalgae oil alone, had a tensile strength improved by 13.76% compared with comparative example 1; comparative example 5, which used hydrolyzed wheat protein alone, had a 13.16% improvement in tensile strength over comparative example 1. In conclusion, the tensile strength of the hair conditioner compounded with the microalgae oil and the hydrolyzed wheat protein is obviously higher than that of the hair in comparative examples 2,3,4 and 5, wherein the effect of example 3 is particularly remarkable, and the repairing effect on the hair is best.

TABLE 3 sensory test data

As can be seen from table 3, the examples 1,2,3, 4,5, and 3 were improved in both smoothness and combability of the dry and wet hair as compared with the comparative example 1, and the improvement effect of the comparative example 3 was slightly inferior to that of the examples 1,2,3, 2, and 2. The lifting effect of example 3 is the best.

In conclusion, the hair care composition containing the microalgae oil and the hydrolyzed wheat protein has good effects on repairing hair, and can make the hair stronger, smoother and easier to comb.

The foregoing describes specific embodiments of the present invention. It is to be understood that the invention is not limited to the particular embodiments described above, and that various changes and modifications may be made by one skilled in the art within the scope of the claims without affecting the spirit of the invention.
