Description

Technical Field

[0001] This invention belongs to the field of cosmetic technology, specifically relating to a cosmetic containing pearl powder and its preparation method. Background Technology

[0002] China is one of the earliest countries in the world to utilize pearls. As early as over 4,000 years ago, the *Shangshu Yugong* recorded that river mussels could produce pearls. The *Classic of Poetry*, *Classic of Mountains and Seas*, *Erya*, and *I Ching* also contain records related to pearls. The medicinal use of pearls in China has a history of over 2,000 years. Nineteen ancient medical books, including the *Mingyi Bielu* from the Three Kingdoms period, the *Bencao Jingji* from the Liang Dynasty, the *Haiyao Bencao* from the Tang Dynasty, the *Kaibao Bencao* from the Song Dynasty, the *Bencao Gangmu* from the Ming Dynasty, and the *Leigong Yaoxing Fu* from the Qing Dynasty, all clearly record the therapeutic effects of pearls. Li Shizhen of the Ming Dynasty placed even greater emphasis on the pharmacological effects of pearls, believing that their medicinal efficacy lay in beautifying the skin. Therefore, in the *Bencao Gangmu*, he specifically wrote: "Pearl tastes salty, sweet, cold, and non-toxic; it calms the mind and brightens the eyes; applying pearl to the face makes one's complexion radiant and beautiful." It also recorded various methods of using pearls medicinally. In the preparation of pearl skincare products, the key is to ensure that the pearl powder or pearl extract is not damaged during emulsification and that it is evenly dispersed in the cosmetics to maximize its efficacy. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a cosmetic containing pearl powder and its preparation method. The pearl cosmetic produced by this invention ensures that the effective components of pearl powder and pearl extract are not damaged to the greatest extent during emulsification, and also ensures their uniform dispersion in the product, thus guaranteeing optimal efficacy. The produced pearl cosmetic has a distinctive appearance, with pearl-like particles suspended in a transparent gel. It has a better moisturizing effect than ordinary creams, and the suspended gold foil particles enhance the skin's absorption of nutrients, maximizing the effectiveness of pearl powder and pearl extract in cosmetics.

[0044] The pearl powder in Example 1 and Comparative Examples 1-2 was prepared using the method for producing pearl powder described in Example 1 of Chinese Patent CN102274243 B.

[0045] The cosmetics containing pearl powder in Comparative Examples 1 and 2 were prepared using the preparation method in Example 1, and the corresponding process parameters were kept consistent with the preparation method in Example 1.

[0046] The roles of the raw materials involved in the embodiments and comparative examples of this invention are shown in Tables 1 and 2 below:

[0047] Table 1. Functions of each component in the first component

[0048]

[0049]

[0050] The product contains pearl extract combined with gold foil containing 99.99% gold, which can effectively improve the absorption of pearl extract and enhance the moisturizing effect of the product.

[0051] Table 2 shows the function of each component in the second component.

[0052]

[0053] The premixing of pearl powder and glycerin ensures that the active ingredients are evenly dispersed during the emulsification process, improving skin absorption and guaranteeing the product's effectiveness.

[0054] Stability test: The pearl cosmetics prepared in Example 1 and Comparative Examples 2-3 were placed at a specific temperature for three months to test their stability. The stability of the products was tested and observed to see if they separated into layers, floated oil, changed color, or deformed, so as to ensure the stability of the ingredients during the use of the products and to guarantee the effectiveness of the products. The test results are shown in Table 3-5.

[0055] Table 3. Relevant properties of the pearl cosmetics prepared in Example 1.

[0056] temperature Is it layered? Is there any floating oil? Does it change color? Are the white particles deformed? 45℃ no no no no 4℃ no no no no -18℃ no no no no

[0057] Table 4 shows the relevant properties of the pearl cosmetics prepared in Comparative Example 1.

[0058] temperature Is it layered? Is there any floating oil? Does it change color? Are the white particles deformed? 45℃ no no no slight deformation 4℃ no no no no -18℃ no no no no

[0059] Table 5 shows the relevant properties of the pearl cosmetics prepared in Comparative Example 2.

[0060] temperature Is it layered? Is there any floating oil? Does it change color? Are the white particles deformed? 45℃ no no no Deformation 4℃ no no no slight deformation -18℃ no no no no

[0061] The conclusions drawn from the stability tests in Table 3-5 are that the amount of pearl powder added to skin care products is not necessarily better the higher it is. Excessive addition can affect the stability of the product, thereby affecting its use and effectiveness. Therefore, the present invention selected the pearl powder addition ratio in Example 1, which can both ensure the stability of this pearl cosmetic and give full play to the efficacy of pearl powder, thereby achieving good skin care effects.

[0062] This method produces pearl cosmetics that ensure the effective components of pearl powder and pearl extract are not damaged to the greatest extent during emulsification, while also guaranteeing their uniform dispersion in the formula for optimal efficacy. The resulting pearl cosmetics have a distinctive appearance: a transparent gel containing suspended pearl-like particles. They offer superior moisturizing effects compared to ordinary creams, and the suspended gold foil particles enhance the skin's absorption of nutrients, maximizing the cosmetic's effectiveness.

[0063] The cosmetic containing pearl powder prepared in Example 1 was subjected to consumer use testing: the skin feel and moisturizing effect of the product were tested.

[0064] Consumer selection: Select 10 healthy female consumers aged 18-60 who meet the following criteria: 1. Not sensitive to commonly used cosmetics, not allergic, not allergic dermatitis, and have no history of skin diseases; 2. The test subjects' skin is in a healthy state, without large areas of birthmarks, scratches, white spots, or other skin problems; 3. Not breastfeeding or pregnant women.

[0065] Experimental Method: After cleansing and toning their skin morning and evening, test consumers applied an appropriate amount of this product to their face and neck using the correct method. The skin was observed for significant changes after one week, one month, and three months of use. Test results are shown in Tables 6-8 (total score 10 points).

[0066] Table 6 shows the ratings of the cosmetic containing pearl powder in Example 1 after one week of use.

[0073] Experimental conclusion: After one week of use, consumers experienced improved hydration and moisturization. After one month of use, there were significant improvements in hydration, moisturization, firmness, and smoothness. After three months of use, the improvement in firmness and smoothness was even more pronounced. This demonstrates that the longer the product is used, the more significantly the skin's hydration, firmness, and radiance improve. Long-term use of this product is recommended.
