Description

Technical Field

[0001] The invention belongs to the technical field of daily chemical products, and in particular relates to a granule composition with the functions of easy flushing and soothing oil control and its application. Background Art

[0002] At present, traditional liquid cleansing products are widely used in the market, but they face many problems during use. First, many liquid cleansing products contain more chemical ingredients, which may damage the natural barrier of skin and hair, causing dryness and tightness, especially for consumers with dry or sensitive skin. Secondly, the preservatives, alcohol or other additives in some products may cause skin allergic reactions, leading to discomfort symptoms such as redness, swelling, itching, etc., especially for sensitive people.

[0003] In addition, the production process of liquid cleaning products also faces problems of environmental protection and resource consumption. The production of liquid cleaning products requires a large amount of water resources, and due to their relatively complex formulas and multiple packaging, the waste of water and resources is relatively serious. The water consumption in the manufacturing process, the weight of the liquid during transportation, and the waste of water resources during use will all put pressure on water resources and increase the carbon footprint and environmental burden.

[0004] Therefore, there is an urgent need to develop a solid cleaning product that has mild cleaning ability, is easy to rinse and leaves no residue, which can not only reduce skin irritation and allergic reactions, but also reduce water consumption, has environmental advantages and is easy to transport or carry, meets the dual needs of modern consumers for environmental protection and health, and fills the market gap. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a granular composition and application with the effects of easy flushing and soothing oil control.

[0006] To achieve the above objectives, the technical solutions adopted by the present invention include:

[0007] In the first aspect, the present invention provides a granular composition with easy flushing and soothing and oil-control effects, the granular composition comprising the following components in parts by weight: 21-73 parts of a composite surfactant, 2.1-21 parts of a moisturizer, 1-4.9 parts of a soothing ingredient, 10-20 parts of a filler, 1-5 parts of an anti-caking agent and 0.1-1 parts of a thickener; the composite surfactant comprises a cationic surfactant, an anionic surfactant and an amino acid surfactant; the cationic surfactant comprises at least one of distearyl dimethyl ammonium chloride and guar hydroxypropyl trimethyl ammonium chloride; the anionic surfactant comprises sodium cocoyl isethionate and sodium C14-16 olefin sulfonate; the amino acid surfactant comprises sodium lauroyl glutamate.

[0008] When the specific cationic surfactant, anionic surfactant and amino acid surfactant components selected by the present invention are combined to prepare a solid washing and care particle composition, the surfactants cooperate with each other to effectively remove grease or dirt on the skin surface, improve the oil control and cleaning ability of the composition, maintain the moisture balance of the skin or hair, exert a certain moisturizing and nourishing effect, and reduce dryness and tightness after washing; in addition, the interaction between the specific composite surfactants can give the solid particle composition richer and more delicate foam during washing, and can be quickly dissolved and easy to rinse, effectively improving the rinsing efficiency of the particle composition.

[0009] Through experimental research, it was found that the solid cleaning particles prepared by the present invention through the reasonable combination of the above-mentioned composite surfactant with moisturizers, soothing ingredients and other components can achieve a full balance in oil control and cleaning ability, moisturizing and soothing, foaming effect, and easy water filling. Compared with traditional liquid cleaning products, the solid particle composition of the present invention does not need to add any preservatives to maintain the long-term stability of the product, avoids skin itching and allergic reactions caused by preservatives and other ingredients, and is suitable for people with sensitive skin. In addition, the particle composition can significantly reduce the consumption of water resources, and the volume is greatly reduced, which is easy to transport or carry. At the same time, the solid particles with relatively low water activity can effectively maintain the stability of the soothing active ingredients therein, thereby providing users with a more ideal use experience.

[0010] Preferably, the granular composition comprises the following components in parts by weight: 30.5-57.5 parts of complex surfactant, 8.3-18.8 parts of moisturizer, 1.9-3.7 parts of soothing ingredient, 15-20 parts of filler, 2-4 parts of anti-caking agent and 0.2-0.8 parts of thickener.

[0011] Preferably, the granular composition comprises the following components in parts by weight: 50.5 parts of complex surfactant, 14.5 parts of moisturizer, 2.6 parts of soothing ingredient, 20 parts of filler, 3 parts of anti-caking agent and 0.5 parts of thickener.

[0012] Through experimental research, it was found that when the components described in the present invention are compounded using the above-mentioned optimal dosage ratio, the overall use effect of the prepared granular composition is the best, and the water activity of the granular composition is relatively the lowest, which can significantly improve the stability of the composition and improve its solubility, thereby maximizing the product use effect.

[0013] Preferably, the composite surfactant is a compound of distearyl dimethyl ammonium chloride, sodium C14-16 olefin sulfonate, sodium cocoyl isethionate and sodium lauroyl glutamate; the mass ratio of distearyl dimethyl ammonium chloride, sodium C14-16 olefin sulfonate, sodium cocoyl isethionate and sodium lauroyl glutamate is (0.1-3):(1-10):(15-35):(5-25).

[0014] Preferably, the mass ratio of the distearyl dimethyl ammonium chloride, sodium C14-16 olefin sulfonate, sodium cocoyl isethionate and sodium lauroyl glutamate is (0.5-2.5):(2-5):(20-35):(8-15).

[0015] More preferably, the mass ratio of the distearyl dimethyl ammonium chloride, sodium C14-16 olefin sulfonate, sodium cocoyl isethionate and sodium lauroyl glutamate is 2:3.5:35:10.

[0016] Through experimental investigation, it was found that when the above four surfactants are compounded in a specific ratio, the cleaning and decontamination effect of the granular composition can be significantly improved, the purpose of gentle cleansing and oil control can be achieved, and hydration can be enhanced to exert a certain degree of moisturizing effect, thereby reducing the dryness and tightness of the skin or hair after intensive cleansing.

[0017] Preferably, the soothing ingredients include allantoin, dipotassium glycyrrhizinate, chamomile extract and calendula extract; the mass ratio of allantoin, dipotassium glycyrrhizinate, chamomile extract and calendula extract is (0.5-2):(0.3-0.9):(0.1-1):(0.1-1).

[0018] Preferably, the mass ratio of allantoin, dipotassium glycyrrhizinate, chamomile extract and calendula officinalis extract is (0.8-1.5):(0.5-0.8):(0.3-0.7):(0.3-0.7).

[0019] More preferably, the mass ratio of allantoin, dipotassium glycyrrhizinate, chamomile extract and calendula officinalis extract is 1:0.6:0.5:0.5.

[0020] Through experimental exploration, it was found that when the present invention selects chamomile extract and calendula extract and reasonably combines allantoin and dipotassium glycyrrhizinate as soothing ingredients to prepare the granular composition, the components cooperate with each other to effectively enhance the soothing effect of the composition and avoid discomfort such as dryness and tightness after washing. In particular, there is an obvious synergistic effect between the three active ingredients of dipotassium glycyrrhizinate, chamomile extract and calendula extract, which can effectively neutralize the stimulation of strong cleaning ingredients and provide additional soothing, moisturizing and protective effects, thereby providing a gentler cleaning experience. When any one or more of the three components are missing, the soothing and moisturizing effect of the prepared granular composition is significantly reduced, resulting in dryness and tightness after cleaning.

[0021] Preferably, the moisturizing agent comprises sodium hyaluronate, trehalose and sorbitol; and / or, the filler comprises modified corn starch; and / or, the anti-caking agent comprises magnesium stearate; and / or, the thickener comprises hydroxypropyl methylcellulose.

[0022] Preferably, the mass ratio of sodium hyaluronate, trehalose and sorbitol is (0.1-1):(1-10):(1-10).

[0023] Preferably, the mass ratio of sodium hyaluronate, trehalose and sorbitol is (0.3-0.8):(5-10):(3-8).

[0024] More preferably, the mass ratio of sodium hyaluronate, trehalose and sorbitol is 0.5:9:5.

[0025] Preferably, the granular composition further comprises the following components in parts by weight: 0.2-0.8 parts of a pH adjuster and 0.5-1.5 parts of a fragrance.

[0026] Preferably, the pH adjuster comprises citric acid; and / or the fragrance comprises essence.

[0027] In a second aspect, the present invention also provides a method for preparing the granular composition, comprising the following steps:

[0028] All components are mixed uniformly, crushed into powder, and the powder is compressed and molded at room temperature under a pressure of 50-80 MPa, and then the compressed particles are dried and solidified at 50-60° C. for 4-6 hours, and cooled to obtain the particle composition.

[0029] The solid detergent particle composition of the present invention can be prepared by conventional mixing, compression molding and drying and solidification processes. The preparation process has no significant effect on the soothing and oil control effects of the final detergent particles, and can greatly improve the convenience of logistics and use. Compared with traditional liquid products, solid detergent particles have the advantages of smaller volume, safer transportation, high efficiency, convenience, and environmental protection.

[0030] In a third aspect, the present invention provides use of the granular composition in the preparation of toiletries.

[0031] Preferably, the toiletries include hair washing products, face washing products and bath products.

[0032] The easy-to-rinse, strong-cleansing and mildly soothing solid particle composition of the present invention can be widely used in personal care products such as shampoo, face wash or bath. Its excellent solubility and cleansing oil-control effect can effectively remove surface dirt and grease. At the same time, due to the moisturizing and soothing properties of the particles, it will not cause irritation to the skin or hair, and is suitable for all skin and hair types. The solid form is not only convenient for storage and transportation, but also can reduce the preservative demand of liquid products, avoid the stimulation of chemical components, and provide a more environmentally friendly, safe and efficient use experience.

[0033] In a fourth aspect, the present invention provides a shampoo particle with easy flushing and soothing and softening effects, wherein the shampoo particle comprises the particle composition, and the shampoo particle also comprises a softener and a hair conditioner.

[0034] Preferably, the softener comprises at least one of argania spinosa kernel oil, jojoba seed oil and coconut oil; and the hair conditioning agent comprises lactobacillus / rye flour fermentation product.

[0035] The present invention only needs to add a hair care factor with specific efficacy to the particle composition, and then adopt the above-mentioned preparation process to prepare the shampoo particles. The preparation method is simple, and active ingredients such as the hair care factor can be effectively wrapped in the shampoo particles, which can avoid degradation or failure during the preparation process or long-term storage, thereby improving the stability and overall performance of the shampoo particles.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] The present invention innovatively develops a solid cleaning particle by combining the selected specific composite surfactant with other ingredients under the preparation process. The components in the cleaning particle cooperate with each other to exert multiple soothing and cleansing oil-control effects, provide excellent mildness and nourishing effects, and compared with traditional liquid cleaning products, the solid cleaning particle can effectively reduce the demand for the use of preservatives, ensure the long-term stability and use effect of the product, and is easy to rinse and residue-free, which can significantly reduce the water consumption during use and reduce the consumption of water resources. The volume is also greatly reduced, which is easy to transport or carry, and can be widely used in personal care products such as shampooing, washing face or bathing.

[0075] Effect example

[0076] 1. Water activity test:

[0077] The granular compositions prepared in Examples 1-8 and Comparative Examples 1-5 and Comparative Example 10 were used as samples, and their water activity was tested. The specific test method was based on the United States Pharmacopoeia-National Formulary General Chapter 922 Water Activity, and the test was performed using a water activity meter. The specific results are shown in Table 3.

[0078] Table 3

[0079] Sample source water activity Sample source water activity Example 1 0.42 Comparative Example 1 0.84 Example 2 0.51 Comparative Example 2 0.73 Example 3 0.49 Comparative Example 3 0.66 Example 4 0.45 Comparative Example 4 0.88 Example 5 0.44 Comparative Example 5 0.80 Example 6 0.54 Comparative Example 10 0.67 Example 7 0.45 Example 8 0.36

[0080] Water activity Aw refers to the availability or activity of water in a substance. It measures the extent to which water can participate in biochemical reactions in a system. In the preparation process of solid cleaning particles, water activity has an important influence on the properties, stability and use effects of the product. Generally speaking, cleaning particle compositions with lower water activity are more helpful in improving product stability, avoiding degradation or failure of active ingredients, and effectively inhibiting the growth and reproduction of microorganisms, thereby reducing the risk of product deterioration. In addition, reducing water activity helps control the generation of foam, achieving a more stable amount of foam and foam quality, making the solid cleaning particles more uniform and easy to clean without residue during use.

[0081] As shown in Table 3, the selection of surfactant has an important influence on the water activity of the granular composition. The water activity of the solid granular composition prepared by the technical solution of the present invention reaches 0.36-0.54, which is significantly lower than that of the comparative example, achieving a balance in the cleaning ability, foam stability and use effect of the composition, and effectively ensuring the stability and performance of the granular composition; while in Comparative Examples 1-5, any one or two of the distearyl dimethyl ammonium chloride, sodium C14-16 olefin sulfonate, sodium cocoyl isethionate and sodium lauroyl glutamate surfactants described in the present invention are lacking, and in Comparative Example 10, when octadecyl dimethyl benzyl quaternary ammonium chloride is replaced by distearyl dimethyl ammonium chloride, the water activity of the granular composition is significantly increased under the same preparation process conditions, resulting in the granular composition being prone to deliquescence or deterioration, and the use experience is worse than that of the embodiment.

[0082] 2. Stability test:

[0083] The solid particle compositions prepared in Examples 1-8 were used as samples to test their stability. The specific method is as follows.

[0084] The internal control standard (high temperature 45±1℃ test for 2 months, low temperature -18±1℃ test for 2 months) is higher than the national standard and light industry standard; high and low temperature cycle test 3 times: 24 hours at high temperature 45±1℃ and low temperature -18±1℃ for one cycle. The results are shown in Table 4.

[0085] Table 4

[0086]

[0087] It can be seen from the results in Table 4 that the solid particle composition prepared by the present invention has a significant stability advantage over the traditional liquid cleaning and care composition, indicating that the present invention converts the traditional liquid cleaning and care products into solid particles, which can significantly improve the stability of the products. This solid particle form can not only maintain the efficacy of the cleaning and care products, but also has obvious advantages in environmental protection, economy, convenience and energy saving.

[0088] 3. Soothing effect test:

[0089] The solid particle compositions prepared in Examples 1-8 and Comparative Examples 6-9 and Comparative Example 11 were used as samples to test their soothing effects. The specific method is as follows.

[0090] Experimental principle: Relevant literature shows that hyaluronic acid is widely present in the skin and other tissues. The relationship between hyaluronic acid and skin is very close. Macromolecular hyaluronic acid can inhibit inflammatory allergic reactions, thereby alleviating the discomfort caused by skin allergies. Macromolecular hyaluronic acid will be degraded under the action of hyaluronidase, resulting in a decrease in the content of macromolecular hyaluronic acid and decomposition to produce the degradation product N-acetylglucosamine. Therefore, the determination of N-acetylglucosamine in the reaction system can indirectly reflect the activity of hyaluronidase. The anti-allergic activity of the sample was evaluated by the in vitro inhibition of hyaluronidase activity experiment. Inhibiting hyaluronidase activity can reduce the degradation of hyaluronic acid and reduce the sensitivity and discomfort of the skin.

[0091] Detection method: The test samples were mixed with hyaluronidase solution, the concentration of the sample in the solution was 5w%, and the mixture was shaken and incubated at 37°C for 10 min. Hyaluronate solution was added and incubated at 37°C for 45 min. BSA solution was added and incubated for another 10 min. The OD600nm value was detected, and the hyaluronidase inhibition rate was calculated according to the following formula. The results are shown in Table 5.

[0092] Hyaluronidase inhibition rate (%) = (1-OD value of sample group / OD value of control group) × 100%

[0093] The sample group is the OD value after adding the test sample, and the control group is the OD value before adding the test sample.

[0094] Table 5

[0095] Sample source Inhibition rate % Sample source Inhibition rate % Example 1 84 Comparative Example 6 58 Example 2 72 Comparative Example 7 56 Example 3 77 Comparative Example 8 61 Example 4 78 Comparative Example 9 42 Example 5 81 Comparative Example 11 64 Example 6 82 Example 7 70 Example 8 87

[0096] As shown in Table 5, the granular composition prepared by the present invention has a good soothing effect, can effectively alleviate and balance the discomfort such as skin or scalp irritation or dryness caused by efficient cleaning ingredients, provide a calming effect, and enhance skin protection ability, reduce barrier damage caused by strong cleaning, so that the product is more gentle and comfortable during use. When any one or two of the three soothing ingredients of dipotassium glycyrrhizinate, chamomile extract and calendula extract are lacking in Comparative Examples 6-9, the hyaluronidase inhibition rate of the prepared granular composition is significantly reduced compared to the embodiment, and when aloe extract replaces chamomile extract in Comparative Example 11, the hyaluronidase inhibition rate of the granular composition is also reduced, that is, the soothing effect of the composition is significantly worse, indicating that the soothing ingredients of dipotassium glycyrrhizinate, chamomile extract and calendula extract selected by the present invention cooperate with each other to better play a synergistic effect, thereby synergistically enhancing the soothing effect of the composition, effectively avoiding the discomfort caused by efficient cleaning.

[0097] 4. Foaming effect test:

[0098] The solid shampoo particles prepared in Application Examples 1-8 and Application Comparative Examples 1-5 and Application Comparative Example 10 were used as samples to test their foaming effects and foam stability. The specific methods are as follows.

[0099] The foaming performance of the samples was evaluated by using a Roche foam instrument: 2.5 g of the shampoo particles provided in Application Examples 1-8 and Application Comparative Examples 1-5 and 10 were prepared into a sample solution with a concentration of 0.2%, 200 mL of each sample solution was flowed down from a pore with a height of 900 mm and an inner diameter of 2.9 mm, and then flushed into 50 mL of a sample solution with the same temperature and concentration, and the foam height when 200 mL of the sample solution flowed was recorded as the evaluation index of the tested foaming ability, and the foam height after foaming for 5 minutes was used as the evaluation index of the foam stability. The test was performed three times, and after taking the average value, the average value of each group was calculated. The specific results are shown in Table 6.

[0100] Table 6

[0101]

[0102] Generally speaking, the foaming effect and foam stability have a certain impact on the cleaning ability of hair care products. Rich and stable foam can effectively improve the application effect, thereby better removing dirt and grease on the surface of the skin or hair, and helping the continuity of the cleaning process. Especially during long-term massage, it can ensure the effect of the product on the scalp or hair, thereby significantly enhancing the product's cleaning and oil control ability and usage experience.

[0103] From the results in Table 6, it can be seen that the shampoo particles prepared by the application examples 1-8 of the present invention have richer foam volume and foam stability, while in the application comparative examples 1-5, due to the absence of one or two components of the composite surfactant defined by the present invention and the replacement of distearyl dimethyl ammonium chloride in the application comparative example 10, the foam volume and foam stability of the prepared shampoo particles are significantly reduced, that is, the cleaning performance and use experience of the shampoo particles are significantly worse than those of the embodiments.

[0104] Figure 1 This is a diagram showing the foaming effect of the shampoo particles prepared in Example 1. As can be seen from the diagram, when the shampoo particles are rubbed with less water, the foam becomes richer and more delicate and stable.

[0105] 5. Flushing effect test:

[0106] The solid shampoo particles prepared in Example 1 were used as samples to investigate the difficulty of flushing with water, and a conventional commercially available shampoo was used as a control sample for comparative testing. The specific method is as follows.

[0107] The subjects rinsed their hands with water with a pH value of 7 until the pH value on the palms of the left and right hands was about 7, then placed 2g of the test sample in the palms, rubbed the samples with the same volume of water for 30 seconds, and then rinsed with water with a pH value of 7 for 10 seconds at the same water flow rate, and then used a pH meter to detect the pH value of the water on the palms to evaluate the ease of rinsing the samples. The test was repeated 5 times and the average value was taken. The specific results are shown in Table 7.

[0108] Table 7

[0109]

[0110] As shown in Table 7, the shampoo particles prepared from the particle composition of the present invention can be quickly dissolved in water compared with traditional shampoo, achieving excellent flushability and no residue effect, thereby significantly reducing the amount of water used during use, while traditional shampoo requires more water to completely remove the residue during flushing. Therefore, the shampoo particles of the present invention have more advantages than traditional shampoo in terms of water consumption, environmental protection, and portability.

[0111] 6. Product performance evaluation test:

[0112] The shampoo particles prepared in Application Examples 1-8 and Comparative Examples 1-11 were used as samples and subjected to sensory evaluation tests.

[0113] 190 subjects aged between 20 and 60 years old and with no skin abnormalities were randomly selected, of which 82 were male and 108 were female. The subjects were randomly divided into 19 groups, 10 in each group, and the solid shampoo particles of application examples 1-8 and comparative examples 1-11 were tried and the samples were evaluated for use experience. Each sample was tried for 2 weeks, and the subjects evaluated the samples using a scoring system based on their use experience. The evaluation items involved cleaning and oil control, foam richness, easy rinsing without residue, and soothing and moisturizing. The scoring standard uses a 10-point system, with 1 point being the worst and 10 points being the best. The evaluation results are the average scores of all subjects in each group as shown in Table 8, and the higher the average score, the better the effect.

[0114] Table 8

[0115]

[0116]

[0117] The results in Table 8 show that the shampoo particles prepared from the particle composition of the present invention can achieve effective balance in multiple aspects such as cleaning and oil control ability, foam effect, easy flushing, moisturizing and soothing effect, and significantly reduce the amount of water used when washing hair. In particular, the shampoo particles prepared by using Examples 1 and 8 have the best comprehensive effect and can provide users with a more ideal use experience. However, due to the lack of components in the specific composite surfactant in the application of Comparative Examples 1-5 and 10, the cleaning and oil control effect and foam quality of the shampoo particles will be significantly affected. Due to the lack of dipotassium glycyrrhizinate, chamomile extract or calendula extract in the application of Comparative Examples 6-9 and 11, the soothing and moisturizing effect of the shampoo particles will be significantly deteriorated, and the scalp will be dry, tight or slightly irritated to a certain extent after cleaning.

[0118] Finally, it should be noted that the above embodiments are intended to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
