Description

Shampoo composition for improving oily scalp

Technical Field

The invention belongs to the field of daily chemicals, and particularly relates to a shampoo composition for improving oily scalp.

Background

Shampoos, also known as shampoos, shampoos or shampoos, have the main function of cleansing the hair and scalp, laying the foundation for the styling of the hair, and the purpose of shampooing is to remove dust from the hair and scalp and to wash off excess oil.

When shampooing hair, the hair absorbs water and swells, the hair becomes soft after being wetted, and protective grease is washed away, so that scales of the hair are damaged, and the hair is easy to rigidly break when combing the hair. Meanwhile, due to the loss of protective grease, the skin of the head is stimulated by the external environment, and head cells are promoted to secrete a large amount of grease, which is the reason why the hair is just washed out in the previous day, the hair is oily in the next day, and particularly the hair root is greasy. Therefore, a new technical solution is needed to solve the above problems.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide the shampoo composition for improving the oily scalp, which has certain oil control astringency performance, can adjust the oil balance of the scalp, can improve the problems of scalp inflammation and scalp itching caused by factors such as scalp oil production and the like, and can improve the hair quality health.

In order to achieve the purpose, the invention provides the following technical scheme: a shampoo composition for improving oily scalp comprises the following components in parts by weight:

further, the aloe leaf juice may preferably be aloe vera leaf juice.

By adopting the technical scheme, the humic acid is a main component of organic matters in natural water, the main sources of the humic acid are low-molecular-weight components of soil humus and decomposition and lower plankton of aquatic plants, the basic structure of the humic acid is aromatic ring and alicyclic ring, and the ring is connected with carboxyl, hydroxyl, carbonyl, quinonyl and methoxyl functional group. Due to the influence of various functional groups on the complexity of the molecular structure of the humic acid, the humic acid has a plurality of physical and chemical properties and has good colloid property, solubility, ion exchange property, adsorbability, precipitability, complexation, oxidation-reduction property and thermal stability. Because the aquatic that uses in this application does not contain the halide, the humic acid that adds this moment can promote the good anti-oxidant of shampoo itself and accuse oily performance on the contrary. The mineral salt is a mineral component containing more than 70 trace elements, such as selenium element, magnesium element, zinc element, silicon element, calcium element, sodium element and the like, can supplement various trace element nutrients required by skin cells of the head, enhance the activity of the cells, improve the tolerance of the cells and improve the skin hydration, thereby being beneficial to prolonging the aging, providing prebiotics for skin microorganisms and maintaining the balance of skin biofilms.

Dipotassium glycyrrhizinate has good anti-inflammatory, antiallergic, moisturizing and other effects, can neutralize or reduce toxic substances of cosmetics, and can also reduce or even prevent allergic reactions of certain cosmetics (such as concealer, foundation liquid and other cosmetics).

The aloe vera leaf juice is a pure natural plant raw material, has the effects of sterilizing and diminishing inflammation, healing primary wounds, relieving pain and relieving, and also has good effects of moistening scalp and hair and caring hair roots. Citric acid is a pH conditioner, can adjust the pH of shampoo to 6-6.5, namely weak acidity, and the pH value of human body is generally between 5-6, if the whole environment of scalp is alkaline, certain irritation can be brought to scalp, and dandruff is easily generated.

The added sandalwood essential oil is also called as sandalwood odorant,

a journal named as: olfactary receptor OR2AT4 regulating human hair growth (Olfactory receptor OR2AT4 regulates human hair growth), as noted herein: sandalwood odorant

Specific stimulation of human hair follicle epithelial cells, particularly OR2AT4 on the outer root sheath, results in prolonged human hair growth in vitro by reducing apoptosis and increasing the production of the hair growth elongation factor IGF-1. It is clear from the above paper that human hair follicles may be chemosensory dependently to olfactory receptors and require OR2AT4 mediated signaling to sustain their growth, suggesting that olfactory receptors may be targets for treatment of alopecia, herein by a sandalwood scented chemical agent

The specific stimulation of the hair growth promoter can increase the growth cycle of the hair and effectively maintain the healthy growth of the hair follicle.

And secondly, the amino acid surfactant is used as a cleaning component and is compounded with other surfactants, so that the foaming performance of the amino acid shampoo base can be improved, and the irritation to the scalp caused by the amino acid shampoo base can be effectively reduced after the amino acid surfactant and other surfactants are compounded, so that the amino acid surfactant is milder.

The added dipotassium glycyrrhizinate (white or white-like fine powder) has various effects of bacteriostasis, inflammation diminishing, detoxification, anti-allergy, deodorization and the like; and when the hair conditioner is compounded with amino acid surfactant, aloe leaf juice, humic acid, mineral salt, hair conditioner, humectant, thickener and other substances, the absorption of scalp on the substances can be accelerated to realize synergism. The ester emollient is mainly ester substances, and the ester emollient can also have proper ester endowing effect on hair, can automatically supplement partial oil to the hair after shampooing, thereby forming a protective oil film on the head, and can supplement the problem of water-oil imbalance caused by over shampooing.

In conclusion, the humic acid and mineral salt composite addition can achieve good oil control and convergence effects, promote the activity of head cells and achieve the balance of regulating the microenvironment of the scalp, and meanwhile, the added amino acid surfactant is used as a cleaning component and is compounded with other surfactants, so that the shampoo has good foamability, mild and low stimulation and the effect of reducing dandruff; meanwhile, the aloe leaf juice, dipotassium glycyrrhizinate and the like are compounded to play a role in diminishing inflammation, inhibiting bacteria and moistening the scalp, and the further added ester emollient can supplement partial oil to the hair after shampooing, so that a protective oil film is formed on the head, and the humic acid and mineral salt compound components for astringing and controlling oil are further combined, so that the problem of unbalanced head oil caused by excessive shampooing can be supplemented, and the hair health is improved.

3.8 finally, the series IX software, the computer and the host power supply are shut down

4. Formula for calculation

The carding force reduction degree calculation formula is as follows:

wherein: CombingWork (blank): combing force of blank samples (before shampoo or conditioner treatment); CombingWork (sample): combing force of shampoo or conditioner treated samples. The higher the reduction in combing force, the better the combing, the lower the force required, i.e. the easier the combing, the less the side indicates mechanical breakage.

TABLE 2 combing force test data for hair treated with test samples 1-7 and control sample 1

And (3) test results: as shown in Table 2, the combing force reduction of wet combing of the test samples 1 to 7 was between 0.3591 and 0.3635%, while that of the comparative sample 1 was 0.3102%, while that of the comparative sample 2 was-0.0052%, wherein the histogram (see FIG. 1) of the combing force reduction of wet combing of the test sample 1 and the comparative samples 1 to 2 shows an improvement in wet combing performance after the hair had been washed out, but that of the comparative sample 2 was reduced after the hair had been washed out.

In addition, bar graphs of the combing force reduction degree of dry combing of the sample 1 and the control samples 1-2 (see fig. 2), dry combing performance of both the sample 1 and the control samples 1-2 was reduced after washing hair and drying hair, but the test sample 1 was reduced to the minimum.

In summary, the higher the combing force reduction, the better the combing property, the lower the force required, i.e., the easier the hair management, and the side illustrates the principle that the mechanical hair breakage will be less, whereby it can be found that the combing properties of the sample samples 1 to 7 are better than those of the comparative sample 1, the mechanical hair breakage will be less, and the hair can be managed more easily.

Test II, oil index

Test subjects: the shampoo composition prepared in example 1 was used as test sample 1.

The test method comprises the following steps: randomly searching 6 consumers in a shampoo shop of a certain market, respectively naming the consumers A-F, respectively detecting corresponding grease indexes at the back hair curl and the top of the head of each consumer by adopting a CK skin tester, then washing the hair by adopting a sample 1, drying the hair for 10min after washing the hair, and detecting the grease indexes at the back hair curl and the top of the head again; the fat index of the later brain pronation, parietal area was then measured at 1 and 2 day intervals and recorded in tables 3 and 4, respectively.

TABLE 3 oil index test

TABLE 4 oil index test

And (3) test results: from the data in tables 3 and 4, it can be seen that the oil index after shampooing and within 10min of drying is lower than the oil index before shampooing, and thus sample 1 has a better cleaning effect. And the grease indexes detected 24h and 48h after shampooing are lower than the grease index detected before shampooing (for the first time), so that the sample 1 has a good oil control effect, the occurrence of oil head phenomenon can be reduced, and the effect of improving oily scalp is achieved.
