Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of cosmetics, and particularly relates to an amino acid scrubbing cleaning composition and a preparation method and application thereof. BACKGROUND

[0002] Cleaning products are used to remove dirt on the skin or hair, and keep the skin and hair clean. At present, the cleaning products on the cosmetic market are mainly divided into three categories. The first category is anionic surfactants as the main surfactants, such as sodium olefin sulfonate, lauryl polyether sulfate, and amino acid surfactants. The second category is amphoteric surfactants as the main surfactants, such as alkyl amido betaine and sodium acyl taurate. The third category is nonionic surfactants as the main surfactants, such as alkyl polyglucoside. Sodium olefin sulfonate and lauryl polyether sulfate have rich foam, are easy to thicken, and are cheap. At present, the common washing and caring products on the market are mainly prepared by using the anionic surfactants. In addition to having moderate cleaning ability, the cleaning products should also focus on their conditioning effect and mildness. The amino acid surfactants have good rinsing feeling, rich foam, good mildness, and excellent skin feeling after washing, and are thus commonly used in facial cleansers in recent years.

[0003] Surfactants can clean the oil and dirt on the skin and hair, and also remove normal skin lipids. Excessive use of surfactants can cause dry and tight skin, skin sensitivity and irritation, and damage to the skin barrier. Therefore, the balance between cleaning ability and skin mildness should be maintained when selecting surfactants. Sodium olefin sulfonate and lauryl polyether sulfate commonly used in washing and caring products have too strong degreasing and cleaning ability, and have dry and rough skin feeling after washing, and can also cause excessive skin degreasing, thereby causing eye and skin problems. The skin compatibility of lauryl polyether sulfate is related to the degree of ethoxylation of the fatty alcohol, and thus the skin compatibility and irritation problems, especially the compatibility with eyes and mucous membranes, should be concerned during use. Although alkyl amido betaine and alkyl polyglucoside have good safety and mildness, their foam performance is relatively weak.

[0004] In recent years, with the popularity of precise skin care, people have more and more demand for functional cleaning products. Products with novel concepts, eye-catching appearance, and technological feeling are easily welcomed by consumers. At present, the cleaning products on the market mainly have liquid or paste in the appearance of the dosage form, and some products add scrubbing particles to create a special appearance. The functional cleaning products only have cleaning function, and rarely have other skin care functions. SUMMARY

[0005] In view of the deficiencies of the prior art, the present application provides an amino acid scrubbing cleaning composition and a preparation method and application thereof.

[0006] To achieve the object of the present application, the present application adopts the following technical solutions:

[0009] The amino acid scrub cleaning composition of the present application adopts a mild amino acid-based surfactant system. Compared with an amphoteric surfactant and a glycoside-based system, the present system has rich and delicate foam, rapid foaming performance and easy rinsing, and the skin feels smooth and soft after washing. The cocoyl glycinate is a kind of amino acid surfactant with foam boosting and stabilizing effect, which brings rich and delicate foam to the system. The cocamidopropyl hydroxysultaine brings superior foam performance and mildness to the system, which can reduce the irritation of other surfactants in the formula to the skin, mucous membrane and eyes. The sodium cocoyl methyl taurate improves the foaming and stabilizing performance of the system, which is more than one time of sulfate. At the same time, it is an intelligent degreasing surfactant, which can retain cholesterol and does not harm the skin barrier function. The sodium sulfonate hydroxypropyl lauryl glucoside cross-linked polymer can change the micelles of the system, improve the mildness and foam performance of the system. The sugar lipid is a natural mild surfactant, which can improve the rinsing performance and cleaning ability. The present application scientifically matches the surfactant system, and the surfactants complement each other and have synergistic effect, so that the composition has excellent foam performance, mildness and use skin feel.

[0053] The heating temperature can be 80-90℃, such as 81℃, 83℃, 85℃, 87℃, or 89℃.

[0054] The temperature can be lowered to 40-50℃, such as 41℃, 43℃, 45℃, 47℃, or 49℃.

[0055] All the specific point values ​​within the above range can be selected, and will not be elaborated on here.

[0056] Thirdly, the present invention provides the application of the amino acid exfoliating cleansing composition as described in the first aspect in the preparation of cosmetics.

[0061] Compared with the prior art, the present invention has the following beneficial effects:

[0062] (1) This invention uses a mild amino acid-based surfactant system. Compared with amphoteric surfactants and glycoside-based systems, this system has rich and delicate foam, fast foaming performance and easy rinsing, leaving the skin smooth and soft after washing. At the same time, the surfactant is limited to a combination of cocoyl glycinate, cocamidopropyl hydroxysulfonate betaine, sodium cocoyl methyl taurate taurate, sodium lauryl glucoside crosspolymer and glycolipid. The five components complement each other and synergistically improve foam performance, mildness and skin feel.

[0063] (2) This invention addresses the issues of excessive degreasing and foam performance caused by surfactants. It selects a mild, high-foaming amino acid-based surfactant as the main surfactant, combined with betaine, glycosides, and bio-glycolipids to improve foam fineness and foam stability. This results in a mild cleansing system that is sulfate-free, sulfonate-free, preservative-free, and EWG-compliant (all-green) and non-comedogenic, achieving rich foam, intelligent cleansing, moderate degreasing, and no dryness after washing, making it suitable for all skin types. To address the issues of limited skin feel and efficacy, this invention improves conditioning effects by employing a special surfactant system and adding a large amount of amino acids and other active ingredients, resulting in a moisturizing and hydrating feel after washing, with moisturizing and anti-wrinkle effects. Furthermore, the product of this invention also features a technologically advanced appearance and a comfortable exfoliating experience, meeting diverse consumer needs. Attached Figure Description

[0121] Comparative Example 5

[0122] This embodiment provides an amino acid exfoliating cleaning composition and its application. The only difference between the amino acid exfoliating cleaning composition and Example 1 is that it does not contain glycolipids. The reduction in its amount is made up by the mass ratio of cocoyl glycinate, cocamidopropyl hydroxysulfonate betaine, sodium cocoyl methyl taurate taurate, and sodium lauryl glucoside crosspolymer. The remaining components and their amounts are the same as in Example 1, and the preparation method is the same as in Example 1.

[0123] Test Example 1: Stability Assessment

[0124] Test subjects: Samples of Examples 1-11 and Comparative Examples 1-5.

[0125] Test conditions: The test samples were stored at -16℃, 5℃, 25℃, and 45℃ for 3 months respectively. The appearance of the material was observed after 3 months under each condition, and the results are recorded in Table 1 below.

[0126] Table 1

[0127]

[0128] As shown in Example 1, the amino acid abrasive cleaning composition of the present invention exhibits good high and low temperature stability and maintains a good crystalline state under various temperature conditions. As shown in Comparative Example 2, cocamidopropyl hydroxysulfonate and PPG-13-decyltetradecyl alcohol polyether-24 have certain solubilizing abilities and significantly affect the stability and transparency of the system. As shown in Examples 4-6, the composition of the amino acid composition affects the crystalline state and stability.

[0129] Since the stability of Comparative Example 2 and Examples 4-6, 9 did not meet the requirements, the following user experience and efficacy tests were no longer conducted on them.

[0130] Test Example 2: Product Safety Evaluation

[0131] Human skin patch test:

[0132] Human skin patch tests were conducted on Examples 1-3, 7-8, 10-11 and Comparative Examples 1, 3-5 to evaluate their irritation.

[0133] Inspection basis: Chapter 7, Section 2 of the "Cosmetic Safety Technical Specifications" (2015 Edition)

[0134] Test substances: 1% dilutions of samples from Examples 1-3, 7-8, 10-11 and Comparative Examples 1, 3-5

[0135] Negative control: Blank control

[0136] Participants: 30 people in total, male / female, aged 18 to 60 years.

[0137] Select a suitable patch tester and use a closed patch test method. Place 0.020 mL-0.025 mL of the test substance in the patch tester and apply it to the flexor side of the subject's forearm with special adhesive tape. Remove the test substance after 24 hours. Observe the skin reaction at 30 min, 24 h and 48 h after removal. Record the results according to the skin reaction grading standard in the "Cosmetic Safety Technical Specifications" (2015 edition) (see Table 2 below).

[0138] Table 2

[0139]

[0140] Test results: Of the 30 subjects who used the sample from Comparative Example 4, 4 experienced a Grade I reaction 48 hours after the spot treatment device was removed. No adverse skin reactions were observed in the remaining samples 30 minutes, 24 hours, and 48 hours after the spot treatment device was removed. This indicates that the amino acid exfoliating cleansing composition of the present invention has good mildness, and sodium lauryl glucoside sulfonate crosspolymer plays a crucial role in the mildness of the system.

[0141] Test Example 3: Population Trial Evaluation Test

[0142] Test subjects: Samples from Examples 1-3, 7-8, 10-11 and Comparative Examples 1, 3-5;

[0143] Volunteers: 77 women aged 25-40 with sensitive skin were selected and randomly divided into 11 groups of 7 people each. Each group of volunteers tried the samples of Examples 1-3, 7-8, 10-11 and Comparative Examples 1, 3-5 respectively.

[0144] Test area: face;

[0145] Evaluation criteria: foam volume, rinsing ability, comfort, and post-wash moisturizing effect.

[0146] Instructions for use: Take an appropriate amount of the test substance on your hand, apply it evenly to your face and massage. Rinse thoroughly after cleansing. Follow-up surveys were conducted using a questionnaire, with a 5-point scale (5 for best experience, 1 for worst). Users could choose any score between 1 and 5. The average score was taken, and the evaluation results are shown in Table 3 below.

[0147] Table 3

[0148]

[0149] Test results: As can be seen from Examples 1-3, the composition of the present invention has excellent foaming power, rinsing properties, comfort, and post-wash moisturizing effect.

[0150] As can be seen from Examples 7-11, the addition of skin conditioning agents affects the comfort during use and the moisturizing feeling after washing, which can improve the problem of dry skin after washing. The choice of skin conditioning agent also affects the comfort and moisturizing feeling.

[0151] Comparative Examples 1, 3-5 show that cocoyl glycinate has a significant impact on rinsing performance and foam volume; sodium cocoyl methyl taurate taurate affects foaming, foam volume, and post-wash moisturizing sensation; sodium lauryl glucoside sulfonate crosspolymer has a significant impact on mildness and rinsing performance, thus affecting comfort and moisturizing sensation; and glycolipids have a certain impact on rinsing performance and moisturizing sensation. This demonstrates that the surfactant system of this invention, when combined, can result in a product with a superior user experience.

[0152] Test Example 4: Moisturizing Efficacy Test

[0153] Test substance: Samples from Examples 1-3; Control group: Water.

[0154] Volunteers: 15 women, aged 25 to 40;

[0155] Test area: face;

[0156] Instructions for use: Take an appropriate amount of the test substance on your hand, apply it evenly to your face and massage, then rinse thoroughly after cleaning.

[0157] Test Procedure: Volunteers washed and dried their faces, then stabilized them in a temperature- and humidity-controlled laboratory for at least 20 minutes. The moisture content of the stratum corneum on both sides of the face was measured at 0 hours. The left side of the face was cleansed with the test substance, while the right side was cleansed with water. One hour after each cleansing, the moisture content of the stratum corneum in the designated areas was measured.

[0158] The test results are shown in Table 4.

[0159] Table 4

[0160]

[0161] Conclusion: Compared with the control group, the skin moisture content of the amino acid exfoliating cleansing composition of the present invention was higher after 1 hour of use than before use, and the difference in change from 0 to 1 hour was higher than that of the control group, indicating that the product has a certain moisturizing effect after use.
