Disclosure of Invention
The invention mainly aims to provide a moisturizing lipstick and a preparation method thereof, and aims to solve the problem that the moisturizing and moisturizing degree of the lipstick commonly seen on the market at present is not lasting.
In order to achieve the purpose, the invention provides a moisturizing lipstick which comprises the following components in parts by weight: 3-5 parts of beeswax, 5-10 parts of glycolipid, 0.5-2 parts of phytosterol isostearate, 1-3 parts of shea butter, 0.2-1 part of sodium hyaluronate and 0.1-0.5 part of tocopherol acetate.
Glycolipid is a latest generation humectant developed in recent years, is a water-soluble lipid substance, has a structure similar to that of a substance constituting the horny layer of the skin, can quickly permeate into the skin, and is combined with water in the horny layer to form a network structure to lock water.
Shea butter is easily absorbed by skin, and has effects in improving skin softness, promoting regeneration of epidermal cells of skin, recovering skin disorder caused by sunburn, eczema and dermatitis, and absorbing ultraviolet.
Sodium hyaluronate is an acidic mucopolysaccharide, glycolipid is a glycosyl acylglycerol structure, and the two have excellent affinity, can enhance the activity and elasticity of skin cells, and have good hygroscopicity and moisture retention.
The tocopherol acetate belongs to a derivative of vitamin E, is commonly used as an antioxidant in cosmetics, has good antioxidant effect, is an oil-soluble natural substance, is a good nutritional moistening agent for skin, can prevent rancidity oxidation of oil and stabilize the oil when added into a care product. Has excellent effects in moisturizing and maintaining connective tissues, and protecting skin from ultraviolet rays, and can soften skin touch and retain moisture of skin, promote wound healing, prevent inflammation, prevent skin from chapping, and improve black spots.
According to the technical scheme, the beeswax, the glycolipid, the phytosterol isostearate, the shea butter, the sodium hyaluronate and the tocopherol acetate are reasonably matched and combined, so that the obtained moisturizing lipstick is good in thermal stability and pigment dispersibility, and can repair the texture of the lip skin.
As a preferred embodiment of the moisturizing and nourishing lipstick of the present invention, the moisturizing and nourishing lipstick comprises the following components in parts by weight: 4 parts of beeswax, 8 parts of glycolipid, 1 part of phytosterol isostearate, 2 parts of shea butter, 0.5 part of sodium hyaluronate and 0.3 part of tocopheryl acetate.
The inventor finds that when the weight of each raw material is in the proportion, the obtained moisturizing lipstick has better heat stability and better pigment dispersibility.
As a preferred embodiment of the moisturizing and nourishing lipstick of the present invention, the moisturizing and nourishing lipstick further comprises the following components in parts by weight: 10-15 parts of emulsion stabilizer, 25-50 parts of softening agent, 8-18 parts of solvent and 3-6.5 parts of dispersant.

As is apparent from the results shown in tables 2 and 3, the lipsticks prepared in examples 1 to 8 were excellent in stability at 50 ℃, 40 ℃ and-5 ℃ without causing softening of the paste or separation of texture. Furthermore, the lipsticks prepared in examples 1-8 do not peel and dry after being applied for 8 hours, wherein the lipsticks of example 1 have the best moisturizing effect because the moisture content of the skin of the lips is 60% after being applied for 8 hours.
In order to better demonstrate the technical effects of the present application, the inventors also performed comparative tests, the raw material compositions of comparative examples 1 to 5 are shown in table 4, and the preparation methods of comparative examples 1 to 5 are the same as example 1.
TABLE 4 raw material ratios (in parts by weight) of comparative examples 1 to 5
The stability tests were performed on the lipsticks prepared in comparative examples 1-5, and the test results are shown in Table 5 below.
TABLE 5 stability test results of lipstick pastes prepared in comparative examples 1 to 5
The lipstick prepared in comparative examples 1-5 was subjected to a post-application effect test, and the test results are shown in table 6 below.
TABLE 6 results of the lipstick smearing effect test prepared in comparative examples 1 to 5

Lip state after application (drying and peeling)
|
Comparative example 1
|
After 5h, lips are slightly peeled, and the moisture content of skin is 36%
|
Comparative example 2
|
After 4h, lips are slightly peeled, and the moisture content of skin is 34%
|
Comparative example 3
|
After 3 hours, the lips are slightly peeled, and the moisture content of the skin is 30 percent
|
Comparative example 4
|
After 4h, lips are slightly peeled, and the moisture content of skin is 34%
|
Comparative example 5
|
After 3 hours, lips are slightly peeled, and the moisture content of skin is 32 percent |
As is clear from the data in tables 5 and 6, in addition to comparative example 1, lipsticks prepared in comparative examples 2 to 5 show different degrees of softening or texture separation (i.e., oil separation) at 50 ℃, 40 ℃ and-5 ℃ over time. After the lipstick of the comparative example 1 is smeared for 5 hours, lips are slightly peeled, and the moisturizing effect is obviously lower than that of the lipsticks prepared in the examples 1 to 8; the lipsticks of comparative examples 2-5 show a peeling phenomenon in a shorter time of application and have poor moisturizing effect.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the protection scope of the present invention, and although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
