[0051] Furthermore, all three are used in combination with at least one of potassium ions, calcium ions, and sodium ions.

[0052] Among them: K type can form hard and brittle glue;

[0053] I-type and L-type are softer and are mainly used to adjust the texture of the glue to form a soft and elastic glue. By selecting and controlling the proportion of the three, the research and development of new eye shadow sticks or highlighter sticks can be achieved;

[0054] Furthermore, the carbohydrate isomers are commercially available products, and the properties of the carbohydrate isomers are mainly utilized, so they are called carbohydrate isomers. The carbohydrate isomers used this time are commercially available existing chemical products, which are 50% aqueous solutions of carbohydrate isomers, and the components also include trace preservatives. When weighing, the carbohydrate isomers in the formula are calculated by the weight of the mixture. For example, hydrochloric acid exists in liquid form in the chemical field. When it is used specifically, the amount of hydrochloric acid includes the weight of the water therein. It is only for the use of existing products, so it will not be repeated.

[0055] Furthermore, the pearlescent powder includes 10-60 micron synthetic fluorphlogopite and 60-150 micron borosilicate, and the content of a single component does not exceed 40 parts, thereby ensuring that the two materials can work together to improve the glossiness of the product.

[0056] Furthermore, colorants are provided in the pearlescent powder, and different colorants can be selected according to different colors to give the product different colors.

[0080] Example 1

[0081] Mix according to the following components:

[0082] Pearlescent powder, 35 parts;

[0083] Deionized water, 55.4 parts;

[0084] 2 parts Crisp Chondrus crispus mixture, 4 parts K to 1 parts I;

[0088] Prepared using the preparation method.

[0089] Example 1 is the best choice among the formulas. Generally speaking, when it is applied to the market, this formula will also be selected as a benchmark for fine-tuning.

[0090] Comparative Example

[0091] Purchase eye shadow sticks and highlighter sticks from the market. Choose one with water and one with oil. Among them, the water-containing highlighter sticks currently sold on the market still contain a certain proportion of oily substances, and the oily substances are dispersed in the system through emulsifiers. The water-containing eye shadows sold on the market are not in stick form, only in gel form.

[0093]

[0094]

[0095] Testing of finished products

[0096] (1) Stability test

[0097] Example 1 was placed in an environment of -18 degrees, 5 degrees, 25 degrees, 45 degrees, and high and low temperature cycles (-20-0-20-45 degrees alternately), and observed for 1 day, 7 days, 14 days, and 1 month, respectively, to observe its state changes, and apply it to determine whether it can be applied normally. Table 2 was obtained.

[0098] Table 2

[0099]

[0100] This article is aimed at cosmetics that will be sold in the future. It is necessary to consider low temperature environments and high temperature environments in summer, and test their appearance stability. After testing, their appearance stability is high. The tested products were also applied with tests, and it was found that they can be applied normally, and the application process is smooth without breakage or falling off.

[0101] (2) Smear sensory test

[0102] Example 1 and Comparative Examples 1-4 were applied, and the user was asked to judge whether there was a cool feeling and elasticity; after 5 minutes of application, the glossiness was uniformly observed; at the same time, the paste was repeatedly applied 20 times on the arm with normal force to observe the firmness of the paste. Table 3 was obtained.

[0103] Table 3

[0104]

[0105]

[0106] As shown in Table 3, the water cooling and elasticity of the comparative example are not good. In terms of gloss, the oily system can achieve high pearlescent, while the water-containing system has not yet achieved high pearlescent in the form of rods. The product designed in this article has more than 55% water and a high content of pearlescent powder. When applied, it has a very obvious cooling feeling as the water evaporates. The uniquely proportioned hydrogel has obvious elasticity, toughness and strength while maintaining the application strength. There is no slag, no breakage, no collapse, and a light touch can present dense and shining color.

[0107] (3) Film forming speed and durability test

[0108] Example 1 and Comparative Examples 1-4 were applied, and immediately after application and 5 minutes later, the applied area was gently rubbed with fingers to see if the color or product migrated to the fingers. The makeup effect was observed 12 hours after the product was applied to evaluate the durability. Table 4 was obtained.

[0109] Table 4

[0110]

[0111] As shown in Table 4, none of the comparative examples has the characteristics of instant film formation and no migration. The makeup durability of the comparative examples is weaker than that of the examples. As time goes by, the skin becomes oily and the face moves, the glossiness of the water-containing system decreases or disappears, and the oily system has problems of makeup smudge, stuck lines, or makeup removal. The product designed in this article has instant film formation and excellent durability.

[0112] (4) Makeup removal test

[0113] Example 1 and Comparative Examples 1-4 were applied. After 10 minutes, clean water, facial cleanser, and makeup remover were used to remove makeup. Table 5 was obtained.

[0114] Table 5

[0115]

[0116]

[0117] As shown in Table 5, none of the comparative examples can be completely removed with water. Facial cleansing milk can completely remove water-based products, but can only partially remove oil-based products. Cleansing oil can remove all products.

[0118] From Tables 2-5, we can see that the product designed in this article has high water cooling, high pearlescent, instant film formation, good durability, easy to remove by washing, and also has high toughness and strength, and is not easy to break and fall off. Its eye shadow stick and highlighter stick are easier to use and have better makeup effects.

[0119] Embodiment part 1:

[0120] Mix according to the following components:

[0121]

[0122] Other ingredients: appropriate amount of skin conditioning agents, such as glycerin, pentylene glycol, propylene glycol, hexylene glycol and other polyols, as well as caprylyl glycol, p-hydroxyacetophenone, etc.

[0123] The above examples were subjected to stability test and smear sensory test.

[0124] In Example 2, when the water content is higher than 70%, the product has poor chromaticity, weak pearlescent effect after application, slow film forming speed, and is very easy to lose water in the stability test, resulting in obvious shrinkage. In Example 6, when the water content is lower than 50%, the formula is loose in texture, and collapses after being barely formed into a stick shape. At the same time, within this water content range, when the amount of pearlescent powder is 25-45, referring to Examples 3-5, a high pearlescent effect can be achieved, and it can be stably formed into a stick shape and has normal application performance.

[0125] Embodiment Part II:

[0126] Mix according to the following components:

[0127]

[0128] Other ingredients: appropriate amount of skin conditioning agents, such as glycerin, pentylene glycol, propylene glycol, hexylene glycol and other polyols, as well as caprylyl glycol, p-hydroxyacetophenone, etc.

[0129] The above examples were subjected to stability test and smear sensory test.

[0130] Comparison of Examples 7 and 8: When the K type accounts for 50% of the Chondrus crispus mixture, the product is very soft, easily broken, and can barely be spread; adding K type can increase the strength of the stick and reduce breakage. Although Example 8 meets the strength requirements for spreading, the toughness is average, it is easy to fall off when spreading, and the uniformity is poor. After adding the sugar isomers, Examples 9-11 all have obvious Q elasticity, better toughness, and are spread evenly with very little falling off.

[0131] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
