Description

Technical Field

[0001] This invention relates to the field of cosmetics technology, specifically to a natural shampoo and its preparation method. Background Technology

[0002] Dandruff is a common problem that plagues many people. Not only does it affect personal appearance—white flakes clearly visible on black clothing, giving an impression of unkemptness—it can also cause scalp itching. According to relevant research, approximately 50% of adults experience dandruff to varying degrees at some stage of life; this large proportion underscores the prevalence and severity of the problem.

[0003] In addition, long-term severe dandruff problems can also lead to scalp inflammation, such as seborrheic dermatitis, and may even damage hair follicles, causing hair loss and further affecting an individual's appearance and mental health.

[0004] Therefore, this application is submitted. Summary of the Invention

[0005] This invention provides a natural shampoo and its preparation method. The shampoo of this invention has excellent soothing and dandruff-removing effects.

[0006] The present invention solves its technical problem by adopting the following technical solution: A natural shampoo comprising the following components in weight percentages: 8-12% sodium cocoylaminopropionate, 2-5% maltodextrin, 2-4% wild soybean seed extract, 1.2-2% soothing anti-dandruff composition, 0.2-0.6% arborvitae leaf extract, 0.2-0.6% lysozyme, 0.2-0.5% hydrolyzed corn starch, 0.1-0.5% potassium sorbate, 0.1-0.4% citric acid, 0.05-0.1% rosemary extract, 0.05-0.1% Polygonum multiflorum extract, 0.05-0.1% plant extracts, and the balance being water; The soothing anti-dandruff composition comprises jojoba seed extract, soapberry extract, macadamia seed extract, and almond extract in a mass ratio of 1:(0.8~1.2):(0.4~0.6):(0.4~0.6).

[0007] The natural shampoo of this invention has excellent soothing and dandruff-removing effects. By adding jojoba seed extract, soapberry extract, macadamia seed extract and almond extract to the composition, the soothing and dandruff-removing effects are significantly improved through the synergistic effect of the four ingredients.

[0008] The jojoba seed extract is rich in unsaturated fatty acid esters, phytosterols, and polyphenols, which can effectively disrupt the cell permeability of Malassezia, effectively inhibit its activity, regulate scalp lipid secretion, and effectively repair the scalp barrier.

[0009] The Sapindus mukorossi extract can effectively inhibit the DNA replication of Malassezia and regulate the scalp microecology. While inhibiting the proliferation of harmful bacteria, it does not damage beneficial bacteria on the scalp (such as Propionibacterium), thus avoiding the imbalance of the scalp microecology caused by a single antibacterial ingredient and prolonging the duration of the dandruff removal effect.

[0010] Among them, macadamia seed extract has the functions of assisting antibacterial (disrupting bacterial cell membranes) and gentle cleansing (fatty acid ester surface activity, removing oil without irritation), improving the compatibility of the formula system, reducing the irritation of other ingredients, enhancing system compatibility, and relieving dry and itchy scalp.

[0011] The almond extract mentioned above is rich in amygdalin, vitamin E, linoleic acid, and phytosterols, which can help regulate the scalp microecology, inhibit the proliferation of harmful bacteria, and not damage beneficial bacteria on the scalp (such as Propionibacterium spp.), thus avoiding the imbalance of scalp microecology caused by single antibacterial ingredients and prolonging the duration of dandruff removal effect.

[0012] This invention combines jojoba seed extract, soapberry extract, macadamia seed extract, and almond extract, controlling their mass ratios. The nourishing components (fatty acids and vitamins) of the jojoba seed extract and almond extract neutralize the cleansing power of the macadamia seed extract, preventing scalp dryness and tightness. The anti-inflammatory components of the soapberry extract alleviate minor irritation during cleansing and antibacterial processes. The fatty acid esters of the jojoba seed extract and the unsaturated fatty acids of the soapberry extract adsorb onto the hair cuticle surface, filling the gaps between the cuticles and reducing cuticle damage during dandruff removal. The vitamin E of the almond extract and the lipid components of the macadamia seed extract synergistically nourish the hair. The fatty acid esters of the macadamia seed extract have both emulsifying and dispersing effects, promoting the uniform dispersion of the fat-soluble components of the jojoba seed extract and soapberry extract in the aqueous system, preventing component aggregation and reduced activity. The almond extract and the soapberry extract enhance the antioxidant effect of the system, protecting the active ingredients from oxidation. Through the synergistic effect of these four components, gentle dandruff removal is achieved while effectively soothing the scalp, demonstrating broad application prospects.

[0013] As a preferred embodiment of the present invention, the preparation method of the jojoba seed extract is as follows: (1) Grind the jojoba seeds to 20-200 mesh to obtain jojoba seed powder; (2) Add jojoba seed powder, cellulase, hemicellulase, protease and ascorbic acid to water and enzymatically hydrolyze to obtain enzymatic hydrolysate; (3) Pass the enzymatic hydrolysate through a macroporous adsorption resin at a flow rate of 0.8~1.5 BV / h and an elution rate of 0.8~1.5 BV / h. First wash with water for 1~2 BV, then wash with 40~60 wt% ethanol solution for 0.8~2 BV. Collect the ethanol eluent to obtain the filtrate, dry it, and obtain jojoba seed extract.

[0017] In a preferred embodiment of the present invention, the macroporous adsorption resin is AB-8 macroporous adsorption resin.

[0018] As a preferred embodiment of the present invention, the method for preparing the Sapindus mukorossi extract is as follows: (1) Grind the soapberry seeds into powder of 20-200 mesh to obtain soapberry powder; (2) The soapberry powder was subjected to supercritical extraction to obtain the extract; (3) The extract was first ultrafiltered with an ultrafiltration membrane with a molecular weight cutoff of 1000 Da, and then ultrafiltered with an ultrafiltration membrane with a molecular weight cutoff of 5000 Da. After drying, the extract of Sapindus mukorossi was obtained.

[0019] In a preferred embodiment of the present invention, the supercritical extraction uses CO2 as the extractant and 60-75 wt% ethanol as the entrainer.

[0020] In a preferred embodiment of the present invention, the CO2 flow rate is 60~75 mL / min, the extraction temperature is 32~36℃, the extraction pressure is 20~25 MPa, and the extraction time is 40~60 min.
