Description

Technical Field

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

[0002] Hair is a natural high-molecular keratin fiber that covers the scalp. It prevents heat dissipation from the scalp, protects the scalp from damage, and makes the scalp beautiful. Hair keratin fibers are inactive, but light, hot hair, acids, alkalis, oxidants, and reducing agents can damage hair. As people's living standards improve, consumers have higher and higher requirements for the use of hair care products. Ultraviolet rays in sunlight can cause aging of hair and scalp. Photoaging of hair can cause damage such as disulfide bond breakage, lipid oxidation, amino acid degradation, and melanin pigment degradation. The appearance is frizzy, yellow, broken and split, and dull. Hair photoaging protection products mainly have the function of preventing ultraviolet radiation and slowing down damage after exposure.

[0003] However, existing hair care products on the market still have some problems when using them. For example, frequent use of acidic / alkaline shampoos containing oils will cause excessive dissolution of oils in the hair, reducing the protective liquid around the protein, causing the protein to be exposed to the air, exposed to ultraviolet rays, and placed in a dry environment, which increases the possibility of denaturation and breakage, reduces the wet and dry combing properties of the hair, and thus causes problems such as dry hair and split ends.

[0004] Therefore, the present invention aims to provide a care composition that can deeply nourish the hair and strengthen its natural protective layer. By adding specific moisturizing ingredients and anti-inflammatory soothing agents, it can effectively resist the damage of ultraviolet rays to the hair. Its unique formula and process make the care effect significant, and can effectively improve the wet and dry combing properties of the hair, and reduce the problems of dryness, split ends, etc. Summary of the invention

[0054] Step 1: First, add appropriate amount of moisturizer and chelating agent into the blender, turn on the stirring and stir rapidly for 3-8 minutes until the mixture is evenly mixed and free of particles; then add the fat excipient, biomimetic phospholipid, emollient, antioxidant, appropriate amount of fragrance and soothing anti-inflammatory agent B, and stir rapidly for 5-8 minutes until the mixture becomes a paste-like semi-fluid with no visible powder particles;

[0062] Experimental example:

[0063] 1.1 Materials and Instruments

[0064] Homemade fatty alcohol polyoxyethylene ether sodium sulfate (ES, 70%), water-soluble cationic polyquaternary ammonium salt, hexadecyl alcohol, ethylene glycol monostearate, coconut oil fatty acid monoethanolamide, cocamidopropyl betaine (CAB, 30%), polydimethylsilicone (50%), essence, isothiazolinone compound opening, sodium lauryl sulfate are all industrial products; NaH2PO4, Na2HPO4, NaCl are all analytical grade; experimental hair bundles; deionized water. 20RW type CNC stirrer; HH2 type digital display constant temperature water bath; SPX-250IC type artificial climate box; combing instrument and hair gloss measuring instrument are all homemade; FA1604 type digital display electronic balance.

[0065] 1.2 Preparation of shampoo

[0066] Based on the typical formula of conditioning shampoo (see Table 1), four experimental shampoos with different compositions were designed to compare the effects of adding excipients lauric acid ester and polydimethylsilicone on the combing and glossiness of hair, among which the amount of excipient added was (see Table 2).

[0067] 1.3 Combing test

[0068] 1.3.1 Hair washing Select healthy human hair that has not been chemically treated by perming, dyeing, bleaching, etc. as the experimental hair bundles, and wash the hair with warm water at about 40°C. First wash the hair bundles with 10% Kz solution, and then wash the hair with 4 kinds of shampoos in the same steps.

[0069] 1.3.2 The combing test uses a combing instrument to simulate the actual combing process, accurately recording the friction between the comb and different positions of the hair during the combing process from the root to the tip of the hair, i.e. the combing force. The combing force curve measured when the hair is not dry after washing is called the wet combing curve; the combing force curve measured when the hair is dried in an artificial climate chamber after washing is called the dry combing curve.

[0070] 2 Results and discussion

[0071] 2.1 Combing

[0072] 2.1.1 Wet hair combing

[0073] Depend on Figure 3 It can be seen that the wet combing curves all have the maximum combing force at about 7 cm from the hair roots. The maximum combing force of the 1* shampoo without esterifying agent is 480g, the maximum combing force of the 2" shampoo with PGPL is 417g, the maximum combing force of the 3" shampoo with PDMS is 453g, and the maximum combing force of the 4" shampoo with two esterifying agents added at the same time is the smallest, which is 392g. Since esterifying agents are added to the shampoo, part of the esterifying agents accumulate on the surface of the hair during the shampooing process, reducing the friction resistance of the hair surface. In conditioning shampoo, JR-400 and anionic surfactants can form a polymer condensate "cage", and PDMS is wrapped in it. In the actual shampooing process, the water-soluble JR-400 is washed away in large quantities, and PDMS is also lost, leaving only a small amount on the hair surface, and the conditioning effect is weakened. Therefore, although the 3" shampoo improves the wet combing of the hair, the effect is not obvious. The EO and PO chains in the PGPL structure can act as anchoring groups, combining with the sulfhydryl groups in the hair through intermolecular hydrogen bonds and adsorbing on the hair surface, making it difficult to be washed away during shampooing; on the other hand, its soft long fat chains are "exposed" on the hair surface, effectively reducing the friction of the hair surface, so the wet combing properties of 2" and 4" shampoos are significantly improved.

[0074] 2.1.2 Dry hair combing

[0075] Depend on Figure 4 It can be seen that the maximum combing force of the dry combing curves is about 28cm away from the hair roots. The maximum combing force of dry hair with 1* shampoo is 346g, and the maximum combing forces of 2", 3", and 4" are 225, 234, and 211g respectively. The change pattern of the dry hair combing force is consistent with the wet hair combing force, indicating that the excipient also effectively reduces the dry hair combing force. In addition, from the appearance, it can be seen that the addition of the excipient reduces the flying hair and tangled hair caused by static electricity.

[0076] 3 Conclusion

[0077] Lauric acid ester is used as an excipient in shampoo to improve the wet and dry combing properties of hair, with a combing force peak of 417g and 225g, which is better than shampoo containing PDMS in reducing combing force. Therefore, lauric acid ester has a good hair conditioning effect and is suitable for addition to light oil-based shampoo.
