Description

Technical Field

[0001] The present application relates to the field of daily chemical products, and in particular to an odor-removing cream. Background Art

[0002] The scales of dry hair are often open or curled, and the surface is uneven, which easily absorbs odors in the environment, such as hot pot or cigarette smells. In addition, dry hair has no luster and is prone to tangles, causing hair loss.

[0003] Currently, hydrogen peroxide is used to remove hair odors, while essential oils can be added to hair creams to repair dry and tangled hair. However, hydrogen peroxide easily decomposes during the hair cream processing process. Furthermore, when hydrogen peroxide and essential oils are added together, they can easily destroy the essential oils, significantly reducing their repairing effects on hair. Summary of the Invention

[0004] In order to improve the problem in the related art that the plant essential oil components are easily decomposed or destroyed during the hydrogen peroxide processing, resulting in poor deodorizing and repairing effects, the present application also provides a deodorizing cream.

[0005] A deodorizing cream, comprising, by weight, 60-80 parts of deionized water, 3-8 parts of cetearyl alcohol, 1-3 parts of ceteareth-25, 0.5-4 parts of coconut oil, 0.8-2.0 parts of hydroxyethyl cellulose, 0.5-1.5 parts of an antistatic agent, 0.3-1.0 parts of hydrolyzed collagen, 0.5-2.0 parts of polydimethylsiloxane, 0.2-3.0 parts of amino dimethicone, 0.2-0.6 parts of a preservative, and 0.5-3. 0 parts of essence, 0.03-0.15 parts of sodium stannate, 0.2-0.6 parts of etidronate, 0.5-3.0 parts of polyurethane-10, 1.0-2.5 parts of hydrogen peroxide, and 1-2 parts by weight of a modified repair component; wherein the modified repair component includes plant essential oil and a wall material wrapped on the surface of the plant essential oil, the plant essential oil includes tea tree essential oil, lavender essential oil, and cedar essential oil, and the wall material includes sodium starch octenylsuccinate and hydroxypropyl-β-cyclodextrin.

[0006] The deodorizing cream of the present application uses cetearyl alcohol and hydroxyethyl cellulose as thickeners, cetearyl alcohol polyether-25 as an emulsifier, coconut oil, hydrolyzed collagen, polydimethylsiloxane, and amino-terminated polydimethylsiloxane as conditioning agents, hydrogen peroxide as a deodorizing agent, and hydroxyethyl diphosphonic acid and polyurethane-10 as stabilizers for hydrogen peroxide. The plant essential oil is modified by wall coating to obtain a modified repair component, and the modified repair component is used as a repair component for dry hair.

[0007] Among them, hydrogen peroxide can destroy odor molecules through oxidation, but hydrogen peroxide has the problem of poor stability. This application improves the stability problem of hydrogen peroxide in the deodorizing cream through the combined action of hydroxyethyl diphosphonic acid and polyurethane-10. At the same time, polyurethane-10 can also act as a film-forming agent to enhance the gloss of hair. Secondly, the repair effect of the modified repair component is mainly provided by plant essential oils. In this application, the plant essential oils are a combination of tea tree essential oil, lavender essential oil, and cedar essential oil. Tea tree essential oil, lavender essential oil, and cedar essential oil synergistically improve the dry and yellowing problems of hair and reduce the occurrence of tangling and hair loss problems. In addition, sodium starch octenyl succinate and hydroxypropyl-β-cyclodextrin are used to encapsulate the plant essential oils. On the one hand, this is conducive to the uniform dispersion of the plant essential oils in the deodorizing cream. On the other hand, sodium starch octenyl succinate and hydroxypropyl-β-cyclodextrin can be used to protect the plant essential oils and prevent them from being damaged by hydrogen peroxide.

[0008] That is, the deodorizing cream of the present application can achieve the effect of removing odors while improving the repair effect on hair, improving dry and yellow hair, and making hair smooth and tangle-free.

[0009] In some specific embodiments, the preparation method of the modified repair component comprises the following steps: Evenly mixing tea tree essential oil, lavender essential oil and cedar essential oil to obtain plant essential oil; 1.5-2.5 parts by weight of an emulsifier is added to 80 parts by weight of water, and after uniform dispersion, 15 parts by weight of a plant essential oil is added and sheared to form an O / W emulsion; the emulsifier comprises Tween, alkyl glycoside and polyglycerol fatty acid ester; Add 5-10 parts by weight of sodium starch octenylsuccinate to 100 parts by weight of water, raise the temperature to 70-80° C. and stir to obtain an aqueous solution of sodium starch octenylsuccinate; Add 35-40 parts by weight of a 30-40% hydroxypropyl-β-cyclodextrin aqueous solution to the O / W emulsion, stir evenly, then add 30-40 parts by weight of an aqueous solution of sodium starch octenylsuccinate, continue stirring to dissolve evenly, and finally homogenize and spray dry to obtain a modified repair component.

[0010] When preparing the modified repair component, this application additionally introduces a specific emulsifier. At the same time, sodium starch octenylsuccinate and hydroxypropyl-β-cyclodextrin are added in the form of an aqueous solution. Through the combined action of Tween, alkyl glycoside and polyglycerol fatty acid ester and the addition of the wall material in the form of an aqueous solution, it is beneficial to improve the coverage rate of the plant essential oil, which further enhances the deodorizing and repairing effects of the deodorizing cream.

[0011] In some specific embodiments, a hydroxypropyl-β-cyclodextrin aqueous solution with a mass concentration of 30-40% is added in two parts, the first part of the hydroxypropyl-β-cyclodextrin aqueous solution with a mass concentration of 30-40% is added before the sodium starch octenylsuccinate aqueous solution, and the second part of the hydroxypropyl-β-cyclodextrin aqueous solution with a mass concentration of 30-40% is added after the sodium starch octenylsuccinate aqueous solution. The weight ratio of the first part of the hydroxypropyl-β-cyclodextrin aqueous solution with a mass concentration of 30-40% to the second part of the hydroxypropyl-β-cyclodextrin aqueous solution with a mass concentration of 30-40% is (3-4):1.

[0012] In the present application, the hydroxypropyl-β-cyclodextrin aqueous solution is added in two parts, one part is added before the sodium starch octenyl succinate aqueous solution, and the other part is added after the sodium starch octenyl succinate aqueous solution. This is beneficial to prevent the problem of adhesion between the modified repair components. At the same time, it is also beneficial to further increase the coverage rate of the plant essential oil, further reduce the possibility of reaction between hydrogen peroxide and the plant essential oil, and enhance the deodorizing and repairing effects of the deodorizing cream.

[0013] In some specific embodiments, the weight ratio of the tea tree essential oil, lavender essential oil, and cedar essential oil is (3-4): (1-2):3.

[0014] In the present application, the weight ratio of tea tree essential oil, lavender essential oil, and cedar essential oil is within the range of (3-4): (1-2): 3, which is beneficial to further enhance the repair effect, improve the hair quality problem of dry hair, and obtain smooth, shiny, and tangle-resistant hair.

[0015] In some specific embodiments, the weight ratio of Tween, alkyl glycoside and polyglycerol fatty acid ester is (2-3): (1-2):1.

[0016] In the present application, the weight ratio of Tween, alkyl glycoside and polyglycerol fatty acid ester is controlled within the range of (2-3): (1-2): 1, which is beneficial to further improve the coverage rate of plant essential oils, thereby further reducing the possibility of reaction between hydrogen peroxide and plant essential oils, and is beneficial to improving the deodorizing and repairing effects of the deodorizing cream.

[0017] In some preferred embodiments, the weight ratio of Tween, alkyl glycoside and polyglycerol fatty acid ester is 2.5:1.5:1.

[0018] In some specific embodiments, the Tween is Tween 80, and the alkyl glycoside is C12-C14 alkyl glycoside.

[0019] In some specific embodiments, the degree of substitution of sodium starch octenyl succinate used in the sodium starch octenyl succinate aqueous solution is 0.02-0.03.

[0020] When the degree of substitution of sodium starch octenylsuccinate is 0.02-0.03, it is beneficial to improve the coverage rate of plant essential oils, which is of great significance to improving the stability of plant essential oils.

[0021] In some specific embodiments, during homogenization, the temperature is controlled at 0-5°C and the rotation speed is controlled at 15000-18000 rpm.

[0022] By controlling the temperature and rotation speed during homogenization, the loss of plant essential oil can be reduced, which is beneficial to increasing the content of plant essential oil in the modified repair component.

[0023] In some specific embodiments, during spray drying, the air inlet temperature is 140-150°C, and the air outlet temperature is 80-90°C.

[0024] By controlling the spray drying process, the loss of plant essential oils can be reduced, which is beneficial to increasing the content of plant essential oils in the modified repair components.

[0025] In summary, this application has at least the following beneficial technical effects: (1) Hydrogen peroxide can destroy odor molecules through oxidation, but hydrogen peroxide has the problem of poor stability. This application improves the stability of hydrogen peroxide in the deodorizing cream through the combined action of hydroxyethyl diphosphonic acid and polyurethane-10. At the same time, polyurethane-10 can also serve as a film-forming agent to enhance the gloss of hair.

Tea tree essential oil, lavender essential oil, and cedar essential oil synergistically improve the dry and yellowing problem of hair and reduce the occurrence of tangling and hair loss problems. In addition, sodium starch octenyl succinate and hydroxypropyl-β-cyclodextrin are used to encapsulate the plant essential oils. On the one hand, this is conducive to the uniform dispersion of the plant essential oils in the deodorizing cream. On the other hand, sodium starch octenyl succinate and hydroxypropyl-β-cyclodextrin can be used to protect the plant essential oils and prevent them from being damaged by hydrogen peroxide.

[0041] Performance testing 1. Odor removal ability experiment: 40 volunteers with long dry hair were recruited to test the ability of the deodorizing cream to remove odors adsorbed by the hair. The volunteers were divided into 8 groups on average and each group stayed in a room filled with the smell of hot pot for 30 minutes. After coming out, 5 judges scored the odor of the 40 volunteers' hair and calculated the average score M1. After the evaluation, the 8 groups of volunteers applied equal amounts of the deodorizing cream prepared in different embodiments or comparative examples to the ends of their hair. After 5 minutes, 5 judges scored the odor of the 40 volunteers' hair and calculated the average score M2. The scoring standard is 0-10 points. The closer the score is to 0, the smaller the odor. The greater the difference between M2 and M1, the better the odor removal effect of the deodorizing cream.

The test period was 30 and 60 days. The volunteers washed their hair every two days. After washing their hair, they used deodorizing cream to care for their hair. The improvement of the volunteers' hair quality was tested after one month.

[0043] Table 1 Deodorizing effect of different deodorizing creams Table 2 Combining Example 1 with Comparative Examples 1-2 and Table 1-2, it can be seen that etidronic acid and polyurethane-10 work together to improve the stability of hydrogen peroxide, thereby improving the deodorizing effect of the deodorizing cream.

[0044] Combining Example 1 with Comparative Example 3 and Table 1-2, it can be seen that when hydrogen peroxide is replaced by water, there is basically no deodorizing effect, which shows that hydrogen peroxide has a deodorizing effect.

[0045] Combining Example 1 with Comparative Example 4 and Tables 1-2, it can be seen that when plant essential oils are directly added, they are easily damaged by hydrogen peroxide, resulting in the deodorizing cream being unable to exert its repairing effect. At the same time, the hydrogen peroxide content is reduced, resulting in a significant reduction in the deodorizing effect of the deodorizing cream.

[0046] Combining Example 1 and Example 3 and Table 1-2, it can be seen that in the present application, the weight ratio of Tween, alkyl glycoside and polyglycerol fatty acid ester is controlled within the range of (2-3): (1-2): 1, which is beneficial to further improve the coverage rate of plant essential oils, thereby further reducing the possibility of reaction between hydrogen peroxide and plant essential oils, and is beneficial to improving the deodorizing and repairing effects of the deodorizing cream.

[0047] Combining Example 1 and Example 4 and Table 1-2, it can be seen that: in the present application, the hydroxypropyl-β-cyclodextrin aqueous solution is added in two parts, one part is added before the sodium starch octenyl succinate aqueous solution, and the other part is added after the sodium starch octenyl succinate aqueous solution, which is beneficial to further increase the coverage rate of the plant essential oil, thereby further reducing the possibility of reaction between hydrogen peroxide and the plant essential oil, which is beneficial to enhance the deodorizing effect and repairing effect of the deodorizing cream.
