Description

Technical Field

[0001] This invention belongs to the field of daily chemical products technology, and in particular relates to a granular composition and its application that has easy-to-rinse and soothing oil-controlling effects. Background Technology

[0002] Currently, traditional liquid hair care products are widely used in the market, but they face many problems during use. First, many liquid hair care products contain a significant amount of chemical ingredients, which may disrupt the skin and hair's natural barrier, leading to dryness and tightness, especially for consumers with dry or sensitive skin. Second, preservatives, alcohol, or other additives in some products may cause allergic reactions, leading to discomfort such as redness, swelling, and itching, especially affecting sensitive individuals.

[0003] In addition, the production of liquid personal care products also faces environmental and resource consumption issues. The production of liquid personal care products requires a large amount of water resources, and due to their relatively complex formulas and multiple packaging, water and resources are wasted in a serious manner. Water consumption during manufacturing, liquid weight during transportation, and water waste during use all put pressure on water resources and increase carbon footprint and environmental burden.

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

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a granular composition and its application that has easy-to-rinse and soothing oil-controlling effects.

[0006] To achieve the above objectives, the technical solution adopted by the present invention includes:

[0007] In a first aspect, the present invention provides a granular composition having easy-to-rinse and soothing oil-controlling effects, the granular composition comprising the following components in parts by weight: 21-73 parts of a complex 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 complex surfactant includes a cationic surfactant, anionic surfactant, and an amino acid surfactant; the cationic surfactant includes at least one of distearate dimethyl ammonium chloride and guar hydroxypropyl trimethyl ammonium chloride; the anionic surfactant includes sodium cocoyl hydroxyethanesulfonate and sodium C14-16 olefin sulfonate; the amino acid surfactant includes sodium lauroyl glutamate.

[0008] When the specific cationic surfactant, anionic surfactant, and amino acid surfactant components selected in this invention are combined to prepare the solid shampoo and conditioner granule composition, the surfactants work together to effectively remove oil or dirt from 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 granule composition richer and finer foam during washing, and it can dissolve quickly and rinse easily, effectively improving the rinsing efficiency of the granule composition.

[0009] Experimental research has revealed that the solid shampoo and body care granules prepared by the present invention through the rational combination of the above-mentioned composite surfactants with moisturizers, soothing ingredients, and other components achieve a full balance in terms of oil control and cleansing ability, moisturizing and soothing, foaming effect, and easy water refillability. Compared with traditional liquid shampoo and body care products, the solid granule composition of the present invention can maintain the long-term stability of the product without the addition of any preservatives, avoiding skin itching and allergic reactions caused by preservatives and other ingredients, making it suitable for people with sensitive skin. Furthermore, the granule composition can significantly reduce water consumption and greatly reduce volume, making it easy to transport or carry. At the same time, the relatively low water activity of the solid granules can effectively maintain the stability of the soothing active ingredients, thus providing users with a more ideal user experience.

[0010] Preferably, the particulate 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 particulate 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] Experimental research has shown that when the components described in this invention are compounded in the above-mentioned optimal dosage ratio, the resulting granular composition has the best overall performance and the lowest water activity, thereby significantly improving the stability and solubility of the composition and maximizing the product's performance.

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

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

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

[0016] Experimental research has shown that when the above four surfactants are compounded in a specific ratio, the cleaning and stain removal effect of the particulate composition can be significantly improved, achieving the purpose of gentle cleaning and oil control. It also enhances hydration, exerts a certain degree of moisturizing effect, and reduces the dryness and tightness of the skin or hair after strong cleaning.

[0017] Preferably, the soothing ingredients include allantoin, dipotassium glycyrrhizate, chamomile extract and calendula extract; the mass ratio of allantoin, dipotassium glycyrrhizate, 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 glycyrrhizate, chamomile extract and calendula 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 glycyrrhizate, chamomile extract and calendula extract is 1:0.6:0.5:0.5.

[0020] Experimental research revealed that when chamomile extract and calendula extract are rationally combined with allantoin and dipotassium glycyrrhizate as soothing ingredients to prepare the granule composition, the components work synergistically to effectively enhance the soothing effect of the composition, preventing discomfort such as dryness and tightness after washing. In particular, there is a significant synergistic effect among the three active ingredients, dipotassium glycyrrhizate, chamomile extract, and calendula extract, which can effectively neutralize the irritation of strong cleansing ingredients and provide additional soothing, moisturizing, and protective effects, thus providing a gentler cleansing experience. However, when any one or more of the three components are missing, the soothing and moisturizing effect of the prepared granule composition is significantly reduced, resulting in dryness and tightness after cleansing.

[0021] Preferably, the humectant includes sodium hyaluronate, trehalose, and sorbitol; and / or, the filler includes modified corn starch; and / or, the anti-caking agent includes magnesium stearate; and / or, the thickener includes 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 particulate composition further comprises the following components in parts by weight: 0.2-0.8 parts of pH adjuster and 0.5-1.5 parts of fragrance.

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

[0027] Secondly, the present invention also provides a method for preparing the particulate composition, comprising the following steps:

[0028] Mix all components evenly, pulverize into powder, compress the powder into shape at room temperature under a pressure of 50-80 MPa, and then dry and solidify the compressed particles at 50-60℃ for 4-6 hours. After cooling, the particle composition is obtained.

[0029] The solid shampoo and conditioner granule composition of this invention can be prepared using conventional mixing, compression molding, and drying and curing processes. These preparation processes have no significant impact on the soothing and oil-controlling effects of the final shampoo and conditioner granules, and can greatly improve the convenience of logistics and use. Compared with traditional liquid products, solid shampoo and conditioner granules have advantages such as smaller size, safer transportation, higher efficiency, convenience, and environmental friendliness.

[0030] Thirdly, the present invention provides the application of the aforementioned particulate composition in the preparation of personal care products.

[0031] Preferably, the personal care products include shampoo, face wash, and bath products.

[0032] The easily rinseable, highly effective, and gentle solid granule composition of this invention can be widely used in personal care products such as shampoos, facial washes, and bath products. Its excellent solubility and oil-controlling properties can effectively remove surface dirt and grease. At the same time, due to the moisturizing and soothing properties of the granules, it will not irritate the skin or hair, making it suitable for various skin and hair types. Furthermore, the solid form not only facilitates storage and transportation but also reduces the need for preservatives in liquid products, avoids the irritation of chemical components, and provides a more environmentally friendly, safe, and efficient user experience.

[0033] Fourthly, the present invention provides shampoo granules with easy rinsing and soothing / smoothing effects, the shampoo granules comprising the aforementioned granule composition, and the shampoo granules further comprising a softening agent and a hair conditioning agent.

[0034] Preferably, the softener includes at least one of argan kernel oil, jojoba seed oil, and coconut oil; the hair conditioner includes lactobacillus / rye flour fermentation product.

[0035] The present invention only requires adding hair care factors with specific effects to the granule composition and then using the above-mentioned preparation process to obtain the shampoo granules. The preparation method is simple, and the active ingredients such as hair care factors can be effectively encapsulated in the shampoo granules, which can avoid their degradation or failure during the preparation process or long-term storage, thereby improving the stability and overall performance of the shampoo granules.

[0036] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0037] This invention innovatively develops a solid shampoo and conditioner granule by combining a specific composite surfactant with other ingredients using the aforementioned preparation process. The components in the granule work synergistically to provide multiple soothing, cleansing, and oil-controlling effects, offering excellent gentleness and nourishing properties. Furthermore, compared to traditional liquid shampoo and conditioner products, the solid granules effectively reduce the need for preservatives, ensuring the long-term stability and effectiveness of the product. They are also easy to rinse, leave no residue, significantly reduce water consumption, and have a much smaller volume, making them easy to transport and carry. They can be widely used in personal care products such as shampoos, facial cleansers, and body washes. Attached Figure Description

[0058] Comparative Example 10

[0059] This comparative example provides a solid particulate composition that differs from Example 1 only in that it uses octadecyl dimethyl benzyl quaternary ammonium chloride, which is also a cationic surfactant, instead of distearate dimethyl ammonium chloride.

[0073] Application of Comparative Examples 1-11

[0074] This application provides solid shampoo particles prepared from the particulate compositions described in Comparative Examples 1-11. The only difference from Application Example 1 is that the particulate composition provided in Example 1 is replaced with the particulate composition provided in Comparative Examples 1-11.

[0075] Example of effect

[0076] 1. Water activity test:

[0077] The particulate compositions prepared in Examples 1-8, Comparative Examples 1-5, and Comparative Example 10 were used as samples, and their water activity was tested. The specific test method referred to the United States Pharmacopeia-National Formulary General Chapter 922 Water Activity, and a water activity meter was used for testing. 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 degree to which water can participate in biochemical reactions within a system. In the preparation of solid shampoo and conditioner granules, water activity has a significant impact on the product's properties, stability, and performance. Generally, shampoo and conditioner granule compositions with lower water activity are more conducive to improving product stability, preventing the degradation or inactivation of active ingredients, and effectively inhibiting the growth and reproduction of microorganisms, thereby reducing the risk of product spoilage. Furthermore, reducing water activity helps control foam generation, achieving a more stable amount and quality of foam, making the solid shampoo and conditioner granules more uniform, easier to rinse, and residue-free during use.

[0081] As shown in Table 3, the choice of surfactant has a significant impact on the water activity of the particulate composition. The solid particulate composition prepared by the technical solution of this invention achieves a water activity of 0.36-0.54, which is significantly lower than that of the comparative examples. This achieves a balance in terms of cleaning ability, foam stability, and performance, effectively ensuring the stability and performance of the particulate composition. In contrast, comparative examples 1-5 lacked any one or two of the surfactants described in this invention, namely distearyldimethylammonium chloride, sodium C14-16 olefin sulfonate, sodium cocoyl hydroxyethanesulfonate, and sodium lauroyl glutamate. In comparative example 10, when octadecyl dimethyl benzyl quaternary ammonium chloride was replaced with distearyldimethylammonium chloride, the water activity of the particulate composition increased significantly under the same preparation process conditions. This led to the particulate composition being prone to deliquescence or deterioration, and the user experience was inferior to that of the examples.

[0082] 2. Stability Test:

[0083] The solid particulate compositions prepared in Examples 1-8 were used as samples to test their stability. The specific methods are as follows.

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

[0085] Table 4

[0086]

[0087] As shown in Table 4, the solid particle composition prepared by this invention has a significant stability advantage compared with traditional liquid washing and care compositions. This indicates that the present invention transforms traditional liquid washing and care products into solid particles, which can significantly improve the stability of the products. This solid particle form not only maintains the efficacy of washing and care products, but also has obvious advantages in many aspects such as environmental protection, economy, convenience and energy saving.

[0088] 3. Soothing effect test:

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

[0090] Experimental Principle: Relevant literature shows that hyaluronic acid is widely present in the skin and other tissues, and its relationship with the skin is very close. High-molecular-weight hyaluronic acid can inhibit inflammatory and allergic reactions, thus alleviating discomfort caused by skin allergies. High-molecular-weight hyaluronic acid is degraded by hyaluronidase, resulting in a decrease in its content and the production of degradation products such as N-acetylglucosamine. Therefore, measuring N-acetylglucosamine in the reaction system can indirectly reflect the activity of hyaluronidase. The in vitro inhibition of hyaluronidase activity is used to evaluate the anti-allergic activity of the samples. Inhibiting hyaluronidase activity can reduce the degradation of hyaluronic acid and alleviate skin sensitivity and discomfort.

[0091] Detection method: The test sample was mixed with hyaluronidase solution at a concentration of 5 wt%. After shaking and mixing, the mixture was incubated at 37°C for 10 min. Hyaluronic acid salt 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 measured. 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 represents the OD value after the test sample was added, while the control group represents the OD value before the test sample was added.

[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 in this invention has a good soothing effect, effectively relieving and balancing discomfort such as skin or scalp irritation or dryness caused by highly effective cleansing ingredients, providing a calming effect, enhancing skin protection, and reducing barrier damage caused by strong cleansing, thus making the product gentler and more comfortable to use. However, in Comparative Examples 6-9, when any one or two of the three soothing ingredients—dipotassium glycyrrhizate, chamomile extract, and calendula extract—were missing, the hyaluronidase inhibition rate of the prepared granular compositions was significantly lower than in the examples. Similarly, in Comparative Example 11, when aloe vera extract was substituted for chamomile extract, the hyaluronidase inhibition rate of the granular compositions also decreased, indicating a significant deterioration in the soothing effect of the compositions. This demonstrates that the soothing ingredients—dipotassium glycyrrhizate, chamomile extract, and calendula extract—selected in this invention work synergistically to enhance the soothing efficacy of the compositions and effectively avoid discomfort after strong cleansing.

[0097] 4. Foaming effect test:

[0098] The solid shampoo granules obtained from Application Examples 1-8, Comparative Examples 1-5, and Comparative Example 10 were used as samples to test their foaming effect and foam stability. The specific methods are as follows.

[0099] The foaming performance of the samples was evaluated using a Roche foam analyzer: 2.5g of shampoo granules provided in Examples 1-8 and Comparative Examples 1-5 and 10 were used to prepare a 0.2% concentration sample solution. 200mL of each sample solution was poured into a 50mL sample solution with the same temperature and concentration through a fine hole with a height of 900mm and an inner diameter of 2.9mm. The foam height after 200mL of sample solution was poured was recorded as the evaluation index of the foaming ability of the tested sample. The foam height after 5 minutes of foaming was used as the evaluation index of foam stability. The test was conducted three times, and the average value was calculated for each group. The specific results are shown in Table 6.

[0100] Table 6

[0101]

[0102] Generally speaking, foaming effect and foam stability have a certain impact on the cleaning ability of shampoo and conditioner. Rich and stable foam can effectively improve the application effect, thereby better removing dirt and oil from the surface of the skin or hair, and help the cleansing process to continue. Especially during long-term massage, it can ensure the product's effect on the scalp or hair, thus significantly enhancing the product's cleaning and oil control capabilities and user experience.

[0103] As shown in Table 6, the shampoo granules prepared in Examples 1-8 of this invention have a richer foam quantity and foam stability. However, in Comparative Examples 1-5, the absence of one or two components in the composite surfactant specified in this invention and the replacement of distearate dimethyl ammonium chloride in Comparative Example 10 resulted in a significant reduction in foam quantity and foam stability of the prepared shampoo granules. In other words, the shampoo granules were significantly worse in terms of cleaning performance and user experience compared to the examples.

[0104] Figure 1 The figure shows the foaming effect of the shampoo granules prepared in Example 1. As can be seen from the figure, when the shampoo granules are rubbed with a small amount of water, the foam becomes richer and richer with each wash, and the foam is fine and stable.

[0105] 5. Flushing effect test:

[0106] The solid shampoo particles prepared in Example 1 were used as samples to investigate their ease of rinsing. A conventional commercially available shampoo was used as a control sample for comparative testing. The specific methods are as follows.

[0107] The subjects rinsed their hands with water at pH 7 until the pH of their palms was approximately 7. Then, 2g of test sample was placed in the palm of each hand, and the samples were rubbed together with the same volume of water for 30 seconds. Next, the hands were rinsed with water at pH 7 at the same flow rate for 10 seconds. The pH of the water on the palms was then measured using a pH meter to assess the ease of rinsing the sample. The experiment 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 granules prepared from the granular composition of this invention dissolve rapidly in water compared to traditional shampoos, achieving excellent rinsing properties and leaving no residue. This significantly reduces the amount of water used, while traditional shampoos require more water to thoroughly remove residue. Therefore, the shampoo granules of this invention have advantages over traditional shampoos in terms of water consumption, environmental friendliness, 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 for sensory evaluation testing.

[0113] 190 participants aged 20-60 years with normal skin were randomly selected, including 82 males and 108 females. The participants were randomly divided into 19 groups of 10 each. Each group tried the solid shampoo granules from Examples 1-8 and Comparative Examples 1-11, and evaluated their experience. Each sample was used for two weeks. Participants rated the samples based on their experience, including cleansing and oil control, foam richness, ease of rinsing with no residue, and soothing and moisturizing effects. A 10-point scale was used, with 1 being the worst and 10 the best. The evaluation results are shown in Table 8, where a higher average score indicates better results.

[0114] Table 8

[0115]

[0116]

[0117] Table 8 shows that the shampoo granules prepared from the granular composition of the present invention can achieve an effective balance in multiple aspects such as cleaning and oil control, foaming effect, easy rinsing, and moisturizing and soothing effect, and significantly reduce the amount of water used during shampooing. In particular, the shampoo granules prepared in Examples 1 and 8 have the best overall effect and can provide users with a more ideal user experience. However, in Comparative Examples 1-5 and 10, the lack of components in the specific composite surfactant will significantly affect the cleaning and oil control effect and foam quality of the shampoo granules. In Comparative Examples 6-9 and 11, the lack of dipotassium glycyrrhizate, chamomile extract or calendula extract will lead to a significant decrease in the soothing and moisturizing effect of the shampoo granules, and the scalp will experience a certain degree of dryness, tightness or slight irritation after cleaning.

[0118] Finally, it should be noted that the above embodiments are used to illustrate the technical solutions of the present invention and not to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
