Description

Bacteriostatic and fragrance-releasing foam shampoo

Technical Field

The invention relates to a shampoo, and in particular relates to a bacteriostatic fragrance-releasing foam shampoo.

Background

Shampoo is an indispensable daily product in life, and has a wide variety in the market, so that the shampoo meets the most basic cleaning requirement and also focuses on the maintenance of hair quality and scalp. Malassezia can cause hair inflammation, excessive secretion of dandruff and sebum and alopecia, the balance of tinea capitis is damaged, harmful bacteria are bred in large quantity, and if the malassezia is not controlled, imbalance of hair grease and metabolism can be caused, so that the state of the whole scalp is disordered, and the health condition of the scalp is seriously damaged; moreover, excessive sebum secretion can cause the hair to quickly generate odor oil after being washed, which is not beneficial to personal image and social interaction, and the odor oil cannot be covered because the odor oil is quickly volatilized and dissipated due to exposure to air when only an aromatizer is simply added into the shampoo.

Disclosure of Invention

Aiming at the problems in the related art, the invention provides a bacteriostatic fragrance-releasing foam shampoo, which aims to overcome the technical problems in the prior related art.

The technical scheme of the invention is realized as follows:

a bacteriostatic fragrance-releasing foam shampoo is prepared from the following raw materials in parts by weight:

the foaming shampoo has a pH value ranging from 5.0 to 7.0, and is applied to the hair in the form of foam by a foam generating means.

The anionic surfactant provides cleaning and foaming capabilities for the shampoo, and the shampoo is rich in foam by matching with a foam generating device, so that the contact of the bactericidal composition with the scalp and the hair is more sufficient.

The hair is washed to enable the hair to have negative charges, the cationic polymer can form a coacervate to deposit and attach on the surface of the hair, the negative charges are neutralized, the repulsion between the hair is reduced, the hair is smoother, and meanwhile, the sterilization slow-release microcapsules and the fragrance slow-release microcapsules are entrained by the coacervate or are attached to the hair by self, so that the continuous sterilization and fragrance emission after the hair is washed are realized.

The malassezia can cause hair inflammation, dandruff, excessive sebum secretion and alopecia, so the malassezia is inhibited by the bactericidal composition, excessive sebum secretion can cause the hair to quickly generate smelly oil after cleaning, and personal image and social contact are not facilitated, so the fragrance slow-release microcapsule is arranged, and fragrance can be slowly released, so that the smelly oil can be covered; on the other hand, if the hair is only washed and sterilized, the action time is too short, so the bactericidal composition is prepared into the bactericidal sustained-release microcapsules, the action time of the bactericidal composition is prolonged, the bactericidal composition can be used for sterilizing the hair and can also be used for long-acting sterilization through the bactericidal sustained-release microcapsules, the bactericidal effect of the bactericidal composition is improved, and the symptoms of excessive secretion of dandruff and sebum, alopecia and the like are effectively relieved.

Further, the sterilization slow-release microcapsule and the fragrance slow-release microcapsule both comprise a wall material and a core material, the proportion of the wall material to the core material is 1:1.5-2, the core material of the sterilization slow-release microcapsule is a sterilization composition, the core material of the fragrance slow-release microcapsule at least comprises essence, the essence is not specially limited, and the commercially available essence taste is selected according to the propaganda concept design of products.

The wall material is prepared by mixing chitosan, starch and glyceryl monostearate and performing mechanical emulsification, spray drying and the like. The chitosan has unique cationic property, is beneficial to the attachment of the microcapsule to hair, and further releases a core material, the starch is used for ensuring the structural strength of the microcapsule, and the glyceryl monostearate is used as an erodible framework, so that the slow release effect of the invention is realized.

The sterilization composition comprises the following preparation raw materials in parts by weight: 2-5 parts of crushed white sclera, 3-5 parts of Chinese violet extract, 8-12 parts of lightyellow sophora root extract, 3-5 parts of golden cypress extract, 3-8 parts of Chinese honeylocust fruit extract, 3-5 parts of oriental wormwood extract, 8-12 parts of Chinese arborvitae twig extract, 1-2 parts of eugenol, 3-7 parts of belvedere fruit extract, 3-5 parts of common cnidium fruit extract and 8-12 parts of bitter cedar extract.

Alumen, which is prepared by processing and extracting sulfate mineral alunite, has effects of removing toxic substance, killing parasite, eliminating dampness and relieving itching for external use. The herba Violae has effects of clearing away heat and toxic materials, cooling blood, and relieving swelling. The radix sophorae flavescentis has the effects of clearing heat, drying dampness, killing parasites and relieving itching, and can effectively relieve scalp itching. Cortex Phellodendri can prevent skin ulcer, furuncle, miliaria, dandruff and tinea capitis, and relieve itching and pain of scalp. The saponin can effectively kill various fungi remained on the scalp. The herba Artemisiae Scopariae has effects of clearing away damp-heat and relieving scalp pruritus. The Chinese arborvitae twig is mainly used for treating blood heat alopecia and early white beard and hair. The eugenol has strong bactericidal power and antiseptic effect, and can be used as antiseptic of the bactericidal sustained-release microcapsule. The broom cypress fruit has the effects of clearing heat, promoting diuresis, dispelling wind, relieving itching and the like. The fructus cnidii has the effects of resisting bacteria and relieving itching aiming at scalp pruritus and erythra. The unique antibacterial ability of the plant extract is fully utilized, and the components are cooperatively matched to effectively inhibit malassezia, prevent alopecia and relieve itching, inhibit dandruff and repair hair follicles, and serve as the preservative of the application.

Furthermore, the bactericidal composition also comprises p-methoxybenzoic acid and sorbitan caprylate, wherein the p-methoxybenzoic acid has an excellent bactericidal and bacteriostatic effect and has an inhibiting effect on various bacteria and moulds, the sorbitan caprylate is a natural oil without the bactericidal and bacteriostatic effects and has a preservative synergistic effect, the preservative effect of the invention can be further improved by the synergistic effect of the p-methoxybenzoic acid and the sorbitan caprylate, and the pH value range of the foam shampoo is adjusted to 5.5-6.5 from 5.0-7.0. If the pH value is lower than 5.0, the system stability of the invention is adversely affected, and if the pH value is higher than 6.5, the bacteriostatic action of the p-methoxybenzoic acid and sorbitan caprylate is greatly reduced.

Preferably, the fragrance sustained-release microcapsule also comprises plant essential oil, so that the fragrance sustained-release microcapsule not only can release fragrance for a long time, but also can release plant essential oil for nourishing and protecting hair.

Specifically, the plant essential oil is prepared by mixing tea tree oil, almond oil and coconut oil, and has the functions of nourishing and protecting hair. The tea tree oil can assist in improving the sterilization and antibacterial effects of the sterilization composition, but the pure tea tree oil is relatively irritant to the scalp with folliculitis, so that the mild almond oil is added and mixed with the tea tree oil, and the irritation of the tea tree oil to the scalp is reduced; the washed scalp is easy to lose water to form a dry state, and dandruff can be generated quickly, and the coconut oil has a moisturizing effect on the scalp and hair, so that the dandruff generating speed is slowed down.

Preferably, the cationic polymer is one or more of polyquaternium-7, polyquaternium-10 and polyquaternium-67 (Eimegao, USA). The polyquaternium has a plurality of cation positions and hydrocarbon chains in each molecule, can be firmly adsorbed on hair with negative charges after hair washing through the attraction of ion static electricity, so that the hydrocarbon chains with fat are remained on the surface of the cuticle of the hair, thereby having the conditioning effect and leading the hair to achieve the effects of smoothness and easy combing.

The polyquaternium-7 and the polyquaternium-10 can be well compatible with anionic surfactants and amphoteric surfactants. Compared with polyquaternium-10 and polyquaternium-7, the polyquaternium-67 has more excellent hair conditioning function, has excellent touch feeling for different hair qualities, has oleophylic property, and does not generate accumulation phenomenon, so more preferably, the cationic polymer is prepared by mixing the polyquaternium-7 polyquaternium-10 and the polyquaternium-67, and can achieve better hair conditioning effect by synergistic cooperation.

Preferably, the anionic surfactant is disodium laureth sulfosuccinate and/or sodium lauroyl sarcosinate, and has the advantages of mild performance, almost no stimulation to skin and eyes on the premise of ensuring that rich foam can be generated, capability of improving the use experience of users, excellent compounding performance and capability of compounding with various plant essential oils.

Still further, the amphoteric surfactant is disodium cocoamphodiacetate. Since the present invention is applied to the hair in the form of foam, but the foam generating means alone is not sufficient to generate a rich and stable foam, a foam stabilizing design must also be performed in the composition. The addition of the cationic polymer reacts with the anionic surfactant and the amphoteric surfactant, resulting in a decrease in the number of freely moving molecules of the two surfactants in the whole system, and thus fails to sufficiently exert their surface activities, resulting in a decrease in foam, but the smooth efficacy of the present invention is affected if the problem is solved by the decrease of the cationic polymer. The inventor finds that the synergistic combination of the disodium cocoyl amphodiacetate and one or two of disodium laureth sulfosuccinate and sodium lauroyl sarcosinate solves the problem to a certain extent, and can generate rich foam without reducing the dosage of the cationic polymer. In addition, the disodium cocoyl amphodiacetate can increase the viscosity of a system and reduce the size of generated foam, so that the shampoo provided by the invention has more dense foam, the effective ingredients fully contact with scalp and hair, and the use experience of a user is improved.

Considering that the invention is provided with the sterilization slow-release microcapsule and the fragrance slow-release microcapsule, in order to ensure that the two microcapsules can be uniformly distributed in the whole system, the suspension performance of the invention is particularly important, and the inventor finds that the disodium laureth sulfosuccinate and/or sodium lauroyl sarcosinate with large heads and small tails in molecular structure are/is mixed with the disodium cocoyl amphodiacetate with small heads and large tails in molecular structure, so that the lamellar arrangement is favorably formed, namely a structured surfactant system is formed, the invention has better suspension performance, and the microcapsules can be uniformly distributed in the system. The amphoteric surfactant also has the effect of reducing the irritativeness of the anionic surfactant.

Preferably, the thickener is an acrylic acid (ester) copolymer. The invention not only designs the structured surfactant to improve the suspension performance, but also arranges the acrylic acid (ester) copolymer to ensure the invention to have lasting and stable suspension property and good viscosity stability.

Preferably, the humectant is propylene glycol and/or glycerin to prevent the shampoo from carrying away excessive moisture from the scalp.

Preferably, the chelating agent is EDTA-2Na and/or EDTA, chelates alkaline earth metal ions or heavy metal ions, and softens the hardness of water.

Preferably, the pH regulator is one or more of citric acid, sodium citrate, tartaric acid and phosphoric acid, and is used for regulating acidity.

The flavoring agent is not specially limited, and is selected from commercially available essence, and can be consistent with the essence in the flavor sustained-release microcapsule or inconsistent with the essence, so that the effect of enriching flavor levels is achieved.

Preferably, the foam shampoo is prepared from the following raw materials in parts by weight:

the invention has the beneficial effects that: the anionic surfactant is arranged to provide cleaning and foaming capabilities, and the foam generating device is matched to enable the shampoo provided by the invention to generate abundant foam, so that the contact between the bactericidal composition and the scalp and hair is more sufficient. The cationic polymer can form a coacervate to deposit and attach on the surface of hair, neutralizes hair with negative charges after hair washing, reduces repulsion between hairs, enables the hair to be smoother, and meanwhile, the sterilization slow-release microcapsules and the fragrance slow-release microcapsules are entrained by the coacervate or automatically attach to the hair, so that continuous sterilization and fragrance emission after hair washing are realized.

The sterilization composition is arranged to inhibit malassezia and simultaneously serve as a preservative, and the fragrance slow-release microcapsule is also arranged to slowly release fragrance so as to cover odor oil smell generated by excessive sebum secretion; on the other hand, the bactericidal composition is prepared into the bactericidal sustained-release microcapsules, so that the action duration of the bactericidal composition is prolonged, the bactericidal composition can be used for sterilizing the hair when the hair is washed, the long-acting sterilization can be realized through the bactericidal sustained-release microcapsules, the bactericidal effect of the bactericidal composition is improved, and the symptoms such as dandruff, sebum excessive secretion, alopecia and the like are effectively relieved.
