Description

Technical Field

[0001] The present invention relates to the technical field of eyelash adhesives, and more specifically to a formula of an eyelash adhesive containing hyaluronic acid and a manufacturing process. Background Art

[0002] Eyelash adhesive, also commonly known as eyelash glue or eyelash adhesive, is a kind of adhesive specially used to bond false eyelashes to real eyelashes. Its main ingredients include acrylic resin, polyurethane elastomer, water, glycerin, etc. When using it, you should pay attention to choosing the right product and the correct method of use to ensure its safety and effectiveness; However, currently, the existing false eyelash adhesive has a small amount of weak irritating odor, and in actual use, the adhesive is often oxidized due to contact with air during use, which greatly reduces the adhesion effect. At the same time, the traditional adhesive causes the eyelashes to fall off due to drying due to contact with air. Therefore, the present invention provides a formula and a production process for eyelash adhesive containing hyaluronic acid. Summary of the invention

[0014] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. In addition, the forms of the various structures described in the following embodiments are only examples. The formula and production process of the eyelash adhesive containing hyaluronic acid involved in the present invention are not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0015] Reference Figure 1 and Figure 2 The present invention provides a formula of an eyelash adhesive containing hyaluronic acid and a production process, the formula of an eyelash adhesive containing hyaluronic acid and a production process, comprising the following components: 0-5 parts of hyaluronic acid, 5-30 parts of acrylic acid polymer, 5-10 parts of glycerol, 5-10 parts of propylene glycol, 0.1-0.5 parts of citric acid, 0-0.2 parts of pomegranate peel extract, and 0-0.5 parts of methyl hydroxyphenyl ester, wherein the addition of sodium oxide is adjusted according to the pH value of the solvent.

[0016] Among them, the acrylic polymer is a variety of acrylic polymers, that is, the product of polymerization of acrylic monomers, including acrylic homopolymers, acrylic ester copolymers and hydroxyalkyl acrylate copolymers. Acrylic ester copolymers are polymers generated by copolymerization reactions. Acrylic homopolymers are high molecular polymers generated by polymerization reactions of acrylic monomers. Hydroxyalkyl acrylate copolymers are composed of acrylic esters and other copolymerizable monomers.

[0017] The pomegranate peel extract is a water solution obtained by diluting pomegranate peel water obtained by squeezing pomegranate peel after breaking the wall of the pomegranate peel with water.

[0018] The anti-sticking layer is a conventional anti-sticking layer of resin material, and the pomegranate peel extract contained therein refers to a powdery substance obtained by squeezing pomegranate peel water and drying it at low temperature.

[0019] A process for producing an eyelash adhesive containing hyaluronic acid, comprising the following steps: S1. First, dissolve hyaluronic acid and sodium oxide in water respectively and set aside for later use. Then, mix acrylic acid polymer, glycerin, propylene glycol and an appropriate amount of water and add them into the emulsifying pot. Raise the temperature to 80-90°C until they are completely dissolved. Continue stirring and wait for them to cool down. S2. Slowly add pomegranate peel water and continue stirring. During stirring, add the dissolved citrus acid solution and add methyl hydroxyphenyl ester and stir together. After stirring and mixing evenly, test the pH value. If the pH value is less than 5.0-6.0, add an appropriate amount of 1 mol / L sodium bicarbonate solution until the value is within the range of 5.0-6.0, indicating that it is weakly acidic and suitable for skin use. Slowly add hyaluronic acid solution and continue stirring. Since the first added hydroxide will react and consume with acidic substances such as citrus acid, the reaction is not violent due to the weak alkalinity of the sodium bicarbonate solution. At the same time, the materials of the adhesive itself are all weakly acidic, resulting in less sodium bicarbonate solution being added. When the pH value is raised to the range of 5.0-6.0, the addition of hyaluronic acid solution will not affect the hyaluronic acid because of its weak acidity and the hydroxide has been reacted and consumed. S3. Use a homogenizer to homogenize the solution so that each component is evenly dispersed in the solution. At this time, filter the homogenized solution to ensure that some dissolved substances in it are removed, and check whether it meets the use standards. After confirming that it meets the standards, fill it.

[0020] The pomegranate peel water is used as an additive of the adhesive to suppress the odor in the adhesive and has the aroma of pomegranate peel, mainly the terpenes, alcohols and esters therein to emit the aroma.

[0021] Example 1

[0022] Control group: conventional eyelash adhesive; Experimental group 1: 0 parts of hyaluronic acid, 5 parts of acrylic acid polymer, 5 parts of glycerin, 5 parts of propylene glycol, 0.1 parts of citrus acid, 0 parts of pomegranate peel extract, and 0 parts of methyl hydroxyphenyl ester.

[0023] Experimental group 2: 1 part of hyaluronic acid, 5 parts of acrylic acid polymer, 5 parts of glycerin, 5 parts of propylene glycol, 0.1 parts of citrus acid, 0 parts of pomegranate peel extract, and 0 parts of methyl hydroxyphenyl ester.

[0024] Experimental group 3: 1 part of hyaluronic acid, 5 parts of acrylic acid polymer, 5 parts of glycerin, 5 parts of propylene glycol, 0.1 parts of citrus acid, 0.1 parts of pomegranate peel extract, and 0 parts of methyl hydroxyphenyl ester.

[0025] Experimental group 4: 1 part of hyaluronic acid, 5 parts of acrylic acid polymer, 5 parts of glycerin, 5 parts of propylene glycol, 0.1 parts of citrus acid, 0.1 parts of pomegranate peel extract, and 0.1 parts of methyl hydroxyphenyl ester.

[0026] Experimental group 5: 2 parts of hyaluronic acid, 5 parts of acrylic acid polymer, 5 parts of glycerin, 5 parts of propylene glycol, 0.1 parts of citrus acid, 0.1 parts of pomegranate peel extract, and 0.1 parts of methyl hydroxyphenyl ester.

[0027] Experimental group 6: 2 parts of hyaluronic acid, 5 parts of acrylic acid polymer, 5 parts of glycerin, 5 parts of propylene glycol, 0.1 parts of citrus acid, 0.2 parts of pomegranate peel extract, and 0.1 parts of methyl hydroxyphenyl ester.

[0028] The adhesion value range is 0-10, the higher the value, the better the adhesion effect; the safety value range is 0-10, the higher the value, the better the safety effect; the irritation value range is 0-10, the higher the value, the lower the irritating smell; the stability value range is 0-10, the higher the value, the better the stability.

[0029] ;

[0030] In summary, when hyaluronic acid is added, the stability of the adhesive is improved overall. Since hyaluronic acid can help maintain the moisture of eyelashes and reduce the loss and breakage of eyelashes caused by dryness, the stability of the material is improved. When pomegranate peel extract is used, it can be seen from the data that in the experimental group with the addition of pomegranate peel extract, the irritation test item has reduced the irritation odor. Although the traditional adhesive itself has a low odor, in actual use, the irritation odor still exists when it is hot. The adhesive using pomegranate peel extract not only suppresses the irritation odor but also has a faint pomegranate peel fragrance.

[0031] Example 2

[0032] Experimental group 1: 3 parts of hyaluronic acid, 5 parts of acrylic acid polymer, 5 parts of glycerin, 5 parts of propylene glycol, 0.1 parts of citric acid, 0.2 parts of pomegranate peel extract, and 0.1 parts of methyl hydroxyphenyl ester.

[0033] Experimental group 2: 3 parts of hyaluronic acid, 15 parts of acrylic acid polymer, 5 parts of glycerin, 5 parts of propylene glycol, 0.1 parts of citrus acid, 0.2 parts of pomegranate peel extract, and 0.1 parts of methyl hydroxyphenyl ester.

[0034] Experimental group 3: 3 parts of hyaluronic acid, 30 parts of acrylic acid polymer, 5 parts of glycerin, 5 parts of propylene glycol, 0.1 parts of citrus acid, 0.2 parts of pomegranate peel extract, and 0.1 parts of methyl hydroxyphenyl ester.

[0035] Experimental group 4: 3 parts of hyaluronic acid, 15 parts of acrylic acid polymer, 7.5 parts of glycerin, 5 parts of propylene glycol, 0.1 parts of citrus acid, 0.2 parts of pomegranate peel extract, and 0.1 parts of methyl hydroxyphenyl ester.

[0036] Experimental group 5: 3 parts of hyaluronic acid, 15 parts of acrylic acid polymer, 10 parts of glycerin, 5 parts of propylene glycol, 0.1 parts of citrus acid, 0.2 parts of pomegranate peel extract, and 0.1 parts of methyl hydroxyphenyl ester.

[0037] Experimental group 6: 3 parts of hyaluronic acid, 15 parts of acrylic acid polymer, 7.5 parts of glycerin, 7.5 parts of propylene glycol, 0.1 parts of citrus acid, 0.2 parts of pomegranate peel extract, and 0.1 parts of methyl hydroxyphenyl ester.

[0038] ;

[0039] In summary, it can be seen that the present invention has been improved in terms of adhesion, and has also been slightly improved in terms of safety, but has been greatly improved in terms of irritation and stability. The main reason is that hyaluronic acid is an excellent moisturizing ingredient that can help maintain the moisture of eyelashes and reduce the loss and breakage of eyelashes caused by dryness. The addition of punicalagin, an antioxidant ingredient in pomegranate peel extract, helps to improve the quality of the adhesive and reduce the quality degradation caused by oxidation. When used, it will have a unique pomegranate fragrance, which greatly improves the inhibitory effect on irritating odors. At the same time, because the tannic acid component in the pomegranate peel has a certain anti-inflammatory effect, it can reduce the inflammatory response of the skin around the eyes and further protect the eyelashes and the health of the skin around the eyes.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
