It will also be understood that the term "prepared from …," as used herein, is synonymous with "comprising," including, "comprising," "having," "containing," and/or "containing," when used in this specification denotes a stated composition, step, method, article, or apparatus, but does not preclude the presence or addition of one or more other compositions, steps, methods, articles, or apparatuses. Furthermore, the use of "preferred," "preferably," "more preferred," and the like, when describing embodiments of the present invention, is intended to refer to embodiments of the invention that may provide certain benefits, under certain circumstances. However, other embodiments may be preferred, under the same or other circumstances. In addition, the recitation of one or more preferred embodiments does not imply that other embodiments are not useful, nor is it intended to exclude other embodiments from the scope of the invention.

In order to achieve the above purpose, the invention provides a skin-brightening and lifting essence which comprises the following raw materials: humectant, skin conditioner, antioxidant, chelating agent, antiseptic, thickener, emulsifier, and water.

In some preferred embodiments, the feed comprises the following components in parts by weight: 7-14 parts of humectant, 0.1-0.55 part of skin conditioner, 2.6-3.7 parts of antioxidant, 0.02-0.06 part of chelating agent, 0.5-0.9 part of preservative, 0.1-0.15 part of thickening agent, 0.05-0.15 part of emulsifier and water to make up to 100 parts.

In some preferred embodiments, the humectant comprises glycerin, panthenol, and β -glucan, wherein the weight ratio of panthenol to β -glucan is (1-2): (1-4), preferably (1-1.5): (1-3), more preferably 1: 1.5.

in some preferred embodiments, the skin conditioning agent comprises carboxymethyl chitosan, sodium hyaluronate, and orange (CITRUS JUNOS) fruit extract.

In some preferred embodiments, the sodium hyaluronate has a molecular weight of 1300-.

In some preferred embodiments, the carboxymethyl chitosan is 0.05 to 0.35 parts, the sodium hyaluronate is 0.01 to 0.05 parts, and the orange (CITRUS JUNOS) fruit extract is 0.05 to 0.15 parts by weight.

Preferably, the carboxymethyl chitosan is 0.05 to 0.3 part by weight, the sodium hyaluronate is 0.01 to 0.03 part by weight, and the orange (CITRUS JUNOS) fruit extract is 0.1 part by weight.

The applicant finds that the synergistic effect can be generated in the system through compounding carboxymethyl chitosan and sodium hyaluronate, so that the essence has extremely strong moisturizing capability and also has a certain bacteriostatic effect, and the applicant thinks that the possible reason is that: the water molecules are fixed from two aspects through different action modes of the carboxymethyl chitosan and the water molecules, so that excellent moisture retention performance is generated, and on one hand, due to the special structure of the carboxymethyl chitosan, a molecular chain has a plurality of hydroxyl groups, and the carboxymethyl chitosan is combined with moisture through hydrogen bonds and keeps moisture; the applicant also unexpectedly finds that when the sodium hyaluronate with the molecular weight of 1300-1500KDa is adopted, the stratum corneum can be softened, the absorption of other moisturizers by the skin is promoted, particularly the absorption of panthenol and beta-glucan by the stratum corneum is promoted, and the panthenol can moisten the stratum corneum on the surface of the skin after penetrating into the stratum corneum, so that the stratum corneum has a strong moisturizing effect and can stimulate the growth of epithelial cells; the beta-glucan can enhance the metabolism of cells after penetrating into the horny layer and improve the immunocompetence of the skin, and when the beta-glucan and the horny layer are combined at a specific ratio, the beta-glucan and the horny layer can promote the increase of collagen and elastin in the skin, so that the skin protection barrier is enhanced. In addition, certain fructus Citri Junoris (Citrus JUNOS) extract can promote epidermal cell proliferation, inhibit red blood streak, and enhance skin allergy resistance.

In some preferred embodiments, the preservative comprises caprylhydroxamic acid and phenoxyethanol in a weight ratio of (2-5): 1.

preferably, the preservative comprises caprylyl hydroximic acid and phenoxyethanol, and the weight ratio of the caprylyl hydroximic acid to the phenoxyethanol is (2-3): 1.

more preferably, the preservative comprises caprylyl hydroximic acid and phenoxyethanol, and the weight ratio of the caprylyl hydroximic acid to the phenoxyethanol is 2.5: 1.

the cosmetic contains a large amount of nutritional ingredients such as fabric extract ingredients, grease and the like, is very beneficial to the growth and reproduction of microorganisms, loses the efficacy once polluted by the microorganisms and can stimulate the skin, so a certain preservative needs to be added into the cosmetic, in some existing cosmetics, phenoxyethanol is often used as the preservative, but the dosage of the phenoxyethanol needs to be strictly controlled, otherwise, the skin can be irritated and damaged, and the allergy phenomenon easily occurs. On one hand, the caprylyl hydroximic acid synergistic chelating agent inhibits the activity of metal ions in a system together and can also indirectly inhibit the growth of microorganisms, but the caprylyl hydroximic acid synergistic chelating agent has a single antibacterial spectrum and a weak antibacterial effect, the antibacterial spectrum can be expanded after a certain amount of phenoxyethanol is added, and the content of phenoxyethanol is obviously lower than the single dosage of phenoxyethanol preservative, so that the risk of stimulation to skin is greatly reduced.

In some preferred embodiments, the antioxidant comprises allantoin and olive (OLEA EUROPAEA) fruit water.

In some preferred embodiments, the antioxidant comprises allantoin 0.1-0.2 parts, olive (Olea EUROPAEA) fruit juice 2.5-3.5 parts by weight.

In order to endow cosmetics with anti-aging effect, a certain antioxidant needs to be added, the applicant finds that when the antioxidant added into the system adopts a specific allantoin and olive (OLEA EUROPAEA) fruit water ratio, not only can more excellent anti-oxidation effect be achieved, but also the skin can be more moisturized and glossy, the applicant considers that the possible reasons are that the allantoin can improve the hydrophilic power of skin stratum corneum protein molecules, repair damaged stratum corneum and form a water locking film on the skin surface to seal the loss of water, so as to reduce the generation of wrinkles, meanwhile, the olive (OLEA EUROPAEA) fruit water contains various polyphenols, and the active phenolic hydroxyl and benzene ring structures in the structure can well absorb ultraviolet light, the two have a synergistic effect, effectively remove free radicals, inhibit lipid peroxidation and achieve excellent anti-oxidation effect, thereby achieving the purpose of slowing down aging; in addition, allantoin can soften keratin, so that the intercellular space can be filled with water while metabolic aging keratin is peeled off, thereby realizing the moist luster of the skin.

In some preferred embodiments, the thickener is a carbomer or xanthan gum, preferably xanthan gum.

In some preferred embodiments, the chelating agent is disodium EDTA.

In some preferred embodiments, the emulsifier comprises PEG-40 hydrogenated castor oil \ PPG-26-Butaneth-26.

The invention provides a preparation method of skin-brightening lifting essence, which comprises the following steps:

(1) weighing a skin conditioner, a thickening agent and a humectant into a container, and uniformly mixing to obtain a mixture A;

(2) adding water, chelating agent, antioxidant, emulsifier and antiseptic into the mixture A, stirring and dissolving until uniformly mixed, filtering with gauze, and discharging.
