Description

Technical Field

[0001] This invention belongs to the field of daily chemical technology, specifically relating to a composition containing natural plant fermentation liquid for shampoo and its preparation method. Background Technology

[0002] In the current personal care field, shampoo, as a core product for daily cleaning and hair care, has evolved from basic scalp cleansing and dirt removal to a more comprehensive approach that combines hair care and scalp maintenance. Existing shampoo compositions often include surfactants, silicone oils, and moisturizers to achieve cleansing and initial hair care effects. While surfactants effectively remove oil and dirt, some types can irritate the scalp barrier with prolonged use and are difficult to penetrate deep into the hair shaft to fill the gaps between the cuticles. Silicone oils, although forming a temporary protective film on the hair surface and improving smoothness, cannot fundamentally strengthen the hair's structure. Therefore, existing formulas have significant limitations in improving hair resilience and cannot meet consumers' demands for long-lasting, strong hair. Meanwhile, as the basic environment for hair growth, the health of the scalp directly affects the quality and stability of hair growth. Existing shampoo compositions rely heavily on simple vitamin additives for scalp nourishment. These ingredients often remain on the surface of the scalp and are difficult to be effectively absorbed and act on the hair follicles and dermis. They cannot fully regulate the scalp microenvironment or replenish the nutrients needed by the scalp, resulting in poor nourishing and conditioning effects and failing to improve scalp health from the root.

[0003] Therefore, providing a new type of shampoo composition that can both strengthen hair and nourish the scalp has become a technological bottleneck that urgently needs to be overcome in the current daily chemical industry. Summary of the Invention

[0004] The purpose of this invention is to provide a composition containing natural plant fermentation liquid for shampoo and its preparation method, which solves the problems of existing shampoo composition technologies that are difficult to increase hair toughness and have poor scalp nourishing effects.

[0005] The objective of this application can be achieved through the following technical solutions:

[0006] The first aspect of this application provides a shampoo composition containing natural plant fermentation liquid, comprising the following raw materials:

[0007] Isostearyl silk, pea fermentation broth, hydrolyzed hydroxypropyltrimethylammonium chloride, plant extracts, plant essential oils, emulsifiers, deionized water.

[0008] As a preferred embodiment of the present invention, the plant extract includes at least one of hydrolyzed prickly pear cactus flower extract, belamcanda chinensis root extract, and cypress leaf extract; the plant essential oil includes at least one of baobab seed oil, evening primrose oil, avocado oil, camellia seed oil, and macadamia seed oil.

[0009] Preferably, the plant extracts include hydrolyzed prickly pear cactus flower extract and iris root extract; the plant essential oils include baobab seed oil and evening primrose oil;

[0010] Hydrolyzed pear cactus flower extract can enhance the scalp's natural exfoliation ability by activating the activity of endogenous serine proteases in the stratum corneum, preventing the accumulation of scalp keratin that can clog hair follicles and prevent the smooth discharge of oil, thus avoiding problems such as itching or excessive oil production.

[0011] The root extract of Belamcanda chinensis contains isoflavone compounds, which can improve excessive scalp oil production caused by microbial imbalance and inflammation, thereby regulating sebum secretion, reducing the "oily outside and dry inside" phenomenon, and laying the foundation for moisturizing.

[0012] The main components of baobab seed oil include saturated fatty acids, oleic acid, as well as Omega-3, 6, 9 and vitamin C, which can highly moisturize the scalp and relieve dryness and tightness.

[0013] Evening primrose oil is rich in linoleic acid and gamma-linolenic acid, which can replenish the lipids lost by the scalp, repair the damaged barrier structure, improve barrier function, and enhance water retention.

[0017] As a preferred embodiment of the present invention, the method for preparing the pea fermentation liquid includes the following steps:

[0018] Crush pea seeds and mix them with deionized water. Sterilize the mixture under controlled temperature to obtain a fermentation liquid. Add Bacillus licheniformis, Lactobacillus plantarum, and Saccharomyces cerevisiae to the fermentation liquid and ferment under controlled temperature to obtain a fermented material. Sterilize the fermented material under controlled temperature, filter it, centrifuge the filtrate at a controlled speed, and then microfilter it to obtain the pea fermentation liquid.

[0019] As a preferred embodiment of the present invention, the ratio of pea seeds to deionized water is 1g:10-15mL; the inoculation amounts of Bacillus licheniformis, Lactobacillus plantarum, and Saccharomyces cerevisiae are 2-3wt%, 1-2wt%, and 1-1.5wt% of the fermentation liquid, respectively.

[0020] Furthermore, the *Bacillus licheniformis*, *Lactobacillus plantarum*, and *Saccharomyces cerevisiae* have all been activated. The activation method involves inoculating each strain into a commonly used culture medium and culturing it using conventional methods. There are no special requirements for the culture medium and culturing method used, except that they can ensure an effective viable count of *Bacillus licheniformis* ≥ 1 × 10⁻⁶. 8 CFU / mL, effective viable count of Lactobacillus plantarum ≥1×10⁻⁶ 9 If the effective viable count of brewing yeast is ≥2×10⁹ CFU / g, then the objective of this invention can be achieved.

[0021] Preferably, the effective viable count of the *Bacillus licheniformis* is 2 × 10⁻⁶. 8 CFU / mL, the effective viable count of Lactobacillus plantarum is 1×10⁻⁶. 9 CFU / g, the effective viable count of brewer's yeast is 2×10⁻⁶. 9 CFU / g.

[0022] As a preferred embodiment of the present invention, the temperature for temperature-controlled sterilization is 121℃ and the time is 15-20 min; the temperature for temperature-controlled fermentation is 30-35℃ and the time is 24-36 h; the speed for speed-controlled centrifugation is 7000-8000 r / min and the time is 15-20 min; and the pore size of the microfiltration membrane is 0.22 μm.

[0023] The second aspect of this application provides a method for preparing a shampoo composition containing natural plant fermentation liquid, comprising the following steps:

[0024] (1) Mix pea fermentation broth, hydroxypropyltrimethylammonium chloride hydrolysate and deionized water at controlled temperature to obtain dispersion A;

[0025] (2) Mix isostearyl silk, plant essential oil and emulsifier evenly under controlled temperature to obtain dispersion B;

[0026] (3) Mix dispersion A and dispersion B, stir under controlled temperature, add plant extract and stir again, cool, and you will get the finished product containing natural plant fermentation liquid.

[0027] As a preferred technical solution of the present invention, the temperature controlled in step (1) is 35-45℃; the temperature controlled in step (2) is 45-55℃; the temperature controlled for stirring in step (3) is 50-60℃ and the time is 20-30min; the time for re-stirring is 30-60min; and the cooling is cooling to room temperature.

[0028] The third aspect of this application provides the use of a composition containing natural plant fermentation liquid for shampoo preparation, which is added at 3-5% of the total mass of the shampoo.

[0029] The beneficial effects of this invention are:

[0030] (1) In this application, Bacillus licheniformis, Lactobacillus plantarum and Saccharomyces cerevisiae were selected as compound strains to ferment peas. Bacillus licheniformis alone can decompose insoluble proteins into peptides, thereby improving the utilization efficiency of proteins. Combining Bacillus licheniformis with Lactobacillus plantarum can not only fully degrade the proteins in peas, but also maintain a certain carbon and nitrogen source consumption. Saccharomyces cerevisiae can enhance the aroma of the product. In this way, the fermented pea broth can greatly promote the release and enrichment of active substances, and obtain small molecule peptides with better biological activity than the original peas, which are more conducive to the absorption of hair and help restore the disulfide bonds in keratin.

[0031] (2) The isostearyl silk used in this application can regulate the microecological balance of the scalp and fit the outer barrier structure of the hair, thereby repairing the keratin of the hair cuticle with molecules similar to those of the hair cuticle. The fermented pea liquid can effectively help restore the disulfide bonds in the keratin. Hydroxypropyltrimethylammonium chloride hydrolysate can penetrate the cracks in the hair cuticle and fill the gaps in the hair cuticle. Therefore, the three raw materials used in this application can complement each other, so that the resulting composition can effectively repair the hair quality and increase the toughness of the hair, making the hair less prone to breakage.

[0032] (3) Hydrolyzed pear cactus flower extract has an exfoliating effect, Belamcanda chinensis root extract can regulate sebum secretion, baobab seed oil can highly moisturize the scalp, and evening primrose oil can repair the damaged barrier structure. Therefore, the combination of these four ingredients in this application can synergistically improve the scalp condition and achieve the effect of nourishing the scalp. Detailed Implementation

They were then hung to air dry naturally in a constant temperature and humidity environment. Ten hairs were randomly selected, and 3cm of the middle section of each hair was taken to make a test sample.

[0080] The compositions obtained in Examples 1-3 and Comparative Examples 1-6 were added to the same shampoo base to prepare shampoo test samples (the amount of composition added to the shampoo test samples was 4%). The shampoo test samples were prepared into 1 g / L shampoo solutions, and the test samples were completely immersed in each group of shampoo solutions for 15 minutes. After immersion, they were rinsed with deionized water and hung to dry. The test samples were treated twice a day, with an interval of more than 4 hours between the two treatments, for 7 consecutive days. After rinsing and drying, they were ready for testing. Before the test samples were treated with shampoo solutions and after 7 days of treatment, the hair tensile elasticity coefficient of the test samples was tested using a hair tester (brand: Dia-stron, model: MTT175). Three test samples were tested for each shampoo solution, and the final result was the average value. The results are shown in Table 1.
