Description

Technical Field

[0001] The invention belongs to the technical field of daily chemical products, and in particular relates to a hair care composition and a preparation method and application thereof. Background Art

[0002] Modern people pursue fashion and beauty while paying attention to safety and health. Hair dyeing has become a must-have option for most people. However, the chemical reactions in the hair dyeing process will change the surface and internal structure of the hair, causing the hair cuticle to curl up, debonding, and the hair surface to become rough, causing light scattering and losing its luster. The hair protein is lost and the crystallinity decreases, resulting in changes in physical properties such as reduced water retention capacity, reduced tensile strength, and reduced elasticity and toughness. Because the damaged hair loses its outer protective structure and becomes hollow inside, it is difficult to effectively retain the pigment in the hair. For hair after dyeing, how do people choose hair care products that have the functions of enhancing scalp nourishment, hair care, inhibiting hair fading, enhancing hair toughness, softness, and relieving itching and dandruff?

[0003] Existing hair care products generally focus on the wet and smooth effect, and generally contain a large amount of softener. Long-term use can easily cause problems such as dry hair and itchy scalp. In addition, current hair care products lack awareness of scalp nourishment and hair care. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a hair care composition which can deeply moisturize the scalp, enhance the strength and toughness of hair, improve the gloss of hair, and inhibit hair fading, as well as a preparation method and application thereof.

[0060] Effect example

[0061] The efficacy of the hair care compositions prepared in Examples 1-8 and Comparative Examples 1-12 is verified in the following aspects:

[0062] 1. Sensory test evaluation

[0063] 400 people, aged between 23 and 60 years old, including 200 males and 200 females, were selected and divided into 20 groups, each group had 20 people, including 10 males and 10 females with oily scalp and 10 females with dry scalp; the test samples of corresponding test examples 1-8 and comparative examples 1-12 were tested; first, the testers took a small amount of the sample to be tested and applied it behind the ear, and let it stand for 20 minutes to see if there were any discomfort symptoms, redness, swelling, or rash symptoms.

[0066] It can be seen from Table 4 that the hair care composition obtained by the technical solution of the present invention has excellent cleaning effect, antipruritic and anti-dandruff, moisturizing and soothing, repairing effect, soft and smooth, glossy effect, color protection effect and antistatic effect, wherein the scores of all items are above 9.18 points. It can be seen from Example 1 and Comparative Examples 1-12 that no matter when any one of the first to fifth hair care active ingredients and squalane is reduced or when other substances with the same function are used to replace any one of the first to fifth hair care active ingredients and squalane, the sensory score of the hair care composition will be significantly reduced.

[0067] Specifically, in the replacement process, in Comparative Example 7, an equal amount of silicone polyurethane polymer is used to replace the first hair care active. Although the silicone polyurethane polymer can be used to reduce fading, its overall effect is not as good as the first hair care active in the present invention. In Comparative Example 8, an equal amount of stearyl trimethyl ammonium methyl sulfate is used to replace the linoleamidopropyl PG-dimethyl ammonium chloride phosphate polydimethylsiloxane in the second active. Among them, linoleamidopropyl PG-dimethyl ammonium chloride phosphate polydimethylsiloxane can improve the texture of hair and soften it, improve the gloss of hair, have excellent wet combing performance, no accumulation, antistatic, and improve color stability. Stearyl trimethyl ammonium methyl sulfate is an antistatic agent. After replacing it with an equal amount, the corresponding effect cannot be achieved. In Comparative Example 9, when PPG-3 octyl ether is used to replace squalane in an equal amount, although the conventional effect of PPG-3 octyl ether can also brighten the gloss of hair, it does not enhance the hair quality. The effects of elasticity, strength and toughness result in overall performance inferior to that of squalane; in Comparative Example 10, phenoxyethanol is used in equal amounts to replace the third hair care active, wherein phenoxyethanol is used as an antibacterial agent, and its effect is inferior to that of the third hair care active in the present invention; in Comparative Example 11, colloidal silver is used in equal amounts to replace the fourth hair care active, and colloidal silver is a natural antibacterial agent, care agent, deodorant, and acne remover, but when it is used in equal amounts, the comprehensive performance of the obtained product is also reduced; in Comparative Example 12, peony root extract is used in equal amounts to replace the fifth hair care active, and although peony root extract has an inhibitory effect on a variety of bacteria and molds acting on the skin, and has analgesic, anti-inflammatory, antipyretic and allergy inhibition effects, it can be used after dermatitis erosion, dryness, and scab formation to improve local allergic reactions, thereby effectively preventing the recurrence of dermatitis in patients, and is also more friendly to sensitive skin, but when it is used for substitution, the comprehensive performance of the obtained product is poor. The above fully illustrates that the components of the present invention have excellent synergistic effects, and none of them is indispensable.

[0068] 2. Evaluation of color protection effect

[0069] 1) Evaluation of washing fastness

[0070] The evaluation of fastness to washing includes the following methods:

[0071] (1) Hair bundle selection: commercially available bleached hair bundles, specifications: 2.0 g, 20 cm;

[0072] (2) Dyeing: Dye according to the instructions of commercially available hair dyes (L'Oreal Excellence Hair Dye Cream Series, brown-red series, semi-permanent); VitalStyle Plant Hair Dye Cream (European brown series, 5 weeks);

[0073] (3) Hand washing: 20 hair bundles were respectively treated with the composition samples of Examples 1-8 and Comparative Examples 1-12, rubbed for 30 seconds, rinsed with warm water at 40° C. for 1 minute (water flow rate 5 L / min); and dried in a constant temperature drying oven at 48° C.;

[0074] (4) Repeat the hand washing treatment step (3) 30 times, take pictures with a camera after washing with clean water after dyeing (baseline), the 1st, 10th, 20th, and 30th washing and drying, scan the images with Matlab software, and measure the L, a, and b values ​​to calculate the comprehensive chromaticity difference dE 1 value;

[0075] (5) Wash the hair with water in accordance with the above steps (3) and (4) instead of the hair care composition, and finally measure the L, a and b values ​​to calculate the comprehensive chromaticity difference dE 2 value;

[0076] (6) Calculate the degree of color fading relief, where the degree of color fading relief dE x =(dE 2 -dE 1 )×100 / dE 2 .

[0077] The above dE value test method: dyed hair without any treatment, measure the Lab value (including a 0 、b 0 , L 0 Parameters); After washing the dyed hair with the composition samples of the embodiment and the comparative example 30 times, the Lab value (including a, b, L parameters) was measured; the calculation formula of the dE value is:

[0078]

[0079] 2) Light fastness evaluation

[0080] Experimental method: Use the basic step (3) to wash the sample with water, dry it, place it in a UV light box, irradiate it for 2 hours, scan the image with Matlab software, and measure the L, a and b values, and calculate the comprehensive chromaticity difference dE 3 Value; 4 times in total, 20h light fastness test; dyed hair without any treatment, placed in a UV light box, irradiated for 2h; calculate the comprehensive chromaticity difference dE 4 value; finally calculate the degree of color fading relief, where the degree of color fading relief dE y =(dE 4 -dE 3 )×100 / dE 4 ;

[0081] The above dE value test method: dyed hair without any treatment, measure the Lab value (including a 0 、b 0, L 0 Parameters); After washing the dyed hair with the composition samples of the embodiment and the comparative example 30 times, the samples were placed in a UV light box and irradiated for 2 hours, and the Lab value (including a, b, and L parameters) was measured; the calculation formula of the dE value is:

[0082]

[0083] dE in the washing fastness test x and dE of light fastness y The values ​​of are shown in Table 5;

[0084] Table 5

[0085]

[0086]

[0087] It can be seen from Table 5 that the hair care composition obtained by the technical solution of the present invention has excellent fastness to washing and light fastness; specifically, after the hair care composition obtained by the technical solution of the present invention is used, the dE reflecting the fastness to washing is x Above 60%, the dE of light fastness y Above 60%;

[0088] It can be seen from Examples 1 and 6-7 that the mass ratio of the first hair care active ingredient to the second hair care active ingredient will affect the performance of the product. When the mass ratio of the first hair care active ingredient to the second hair care active ingredient is further preferably 1:(0.5-2), the obtained product has better fastness to washing and light fastness.

[0089] It can be seen from Example 1 and Comparative Examples 1-6 that when any one of the first to fifth hair care active ingredients and squalane is reduced, the obtained products have significantly reduced wash fastness and light fastness properties on hair. Compared with Example 1, the wash fastness dE of Comparative Examples 1-6 is x Reduced dE of light fastness by 23.68-56.58% y The results show that the hair care compositions of the present invention have obvious synergistic effects with each other.

[0090] 3. Evaluation of fracture resistance

[0091] A bundle of damaged hair bleached with hydrogen peroxide was selected and divided into 21 equal parts, and the hair care compositions of Examples 1-8 and Comparative Examples 1-12 and deionized water were sprayed uniformly respectively, and then rinsed with warm water at 42° C. for 20 seconds, and placed on a hair dynamic combing instrument to compare the wet combing performance of the 21 hair bundles; after the wet combing performance was measured, the hair bundles were placed in a constant temperature room with a temperature of 25° C. and a humidity of 35%, and naturally dried and then placed on a hair dynamic combing instrument to compare the dry combing performance of the 21 hair bundles; the hair care compositions of Examples 1-8 and Comparative Examples 1-12 and deionized water were sprayed continuously for 1 week, and 21 hair bundles were placed on an MTT175 hair tension tester to measure the hair breaking work; the results are shown in Table 6;

[0092] Table 6

[0093]

[0094]

[0095] It can be seen from Table 6 that the hair care composition obtained by the technical solution of the present invention has excellent wet combing performance and dry combing performance, and the hair after use has good toughness; specifically, after use of the hair care composition obtained by the technical solution of the present invention, the combing force reflecting the wet combing performance is below 0.65N, and the combing force reflecting the dry combing performance is below 0.57N. Compared with the deionized water group, the combing force of the wet combing performance decreased by 48.82%, and the combing force of the dry combing performance decreased by 55.47%. The breaking work reflecting the toughness of the hair is above 0.0195J, and compared with the deionized water group, the breaking work obtained increased by 98.99%;

[0096] It can be seen from Examples 1 and 6-7 that the mass ratio of the first hair care active ingredient to the second hair care active ingredient will affect the performance of the product. When the mass ratio of the first hair care active ingredient to the second hair care active ingredient is further preferably 1:(0.5-2), the obtained product has a better effect on improving combing force and strengthening hair.

[0097] It can be seen from Example 1 and Comparative Examples 1-6 that when any one of the first to fifth hair care actives and squalane is reduced, the improvement of the combing force and the strengthening effect of the obtained products on the hair are significantly reduced. Compared with Example 1, the combing force of the wet combing performance in Comparative Examples 1-6 is increased by 26.42-90.57%, the combing force of the dry combing performance is increased by 41.67-133.33%, and the pull-off work is reduced by 40.25-66.25%; at the same time, it can be seen from Example 1 and Comparative Examples 7-12 that when any one of the first to fifth hair care actives and squalane is replaced by other substances with the same function, the improvement of the combing force and the strengthening effect of the obtained products on the hair are also significantly reduced; Obviously, it can be clearly found from Example 1 and Comparative Examples 1-12 that the hair care compositions of the present invention have obvious synergistic effects.

[0098] Finally, it should be noted that the above embodiments are intended to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
