Description

Light-streak repairing lip cream and preparation method thereof

Technical field:

the invention belongs to the technical field of cosmetics in the light industry, and particularly relates to a light-pattern repairing lip cream and a preparation method thereof.

The background technology is as follows:

the lips are very fragile due to the fact that the lips do not have horny layers, and are easily influenced by the environment, and the problems of dry lips, cracks, pigment deposition, deepening lips and the like can be caused by factors such as weather, food, beverage and the like.

The existing mode of covering the lips on the market mainly comprises physical covering, such as adding an organic silicon elastomer to fill the lips, so as to play a temporary repairing role, however, the silicon elastomer cannot be absorbed by skin, the lips are exposed after washing, and the fundamental problem of the lips is not changed in practical sense. The lip marks are generated in various ways, and the lip marks are gradually increased due to lack of moistening due to the fact that lips are dry; on the other hand, the loss of collagen can also cause the appearance of lip marks, so that the lips are gradually shrunken to show the lip marks, and the anti-aging effect of the lips can also improve the lip marks. From the above, it is clear that improvement of lips is feasible from the aspects of moisture retention, repair, anti-aging and the like.

The extract Luo Mu can fill certain moisture for skin, has strong water locking capacity, can maintain cellular enzymes, can avoid outflow of water in cells, has the effects of moisturizing and moistening, and often has a certain effect on dry skinned skin. The rich Luo Muzhong plant components can stimulate the metabolism of cells, promote the regeneration of the cells, make the skin more elastic and resist the damage and aging of the external environment. The density Luo Mu can also effectively keep sufficient moisture, keep cells active, strengthen cell elasticity, improve the water holding capacity of skin, reduce wrinkles, strengthen skin elasticity and delay skin aging.

Avocado oil, olive oil, phytosterol, butter fruit, cocoa seed fat, and plant squalane belong to vegetable oil or oil extracted from plants, and are effective in softening cutin, smoothing lip streak as lubricating and moisturizing agent of lip product, increasing skin respiration, preventing loss of moisture, softening cutin, and mixing with fibrous protein to lighten lip streak.

Dipalmitoyl hydroxyproline is a palmitoylation derivative of amino acid-hydroxyproline, and can improve the absorptivity of lip skin to hydroxyproline after palmitoylation, and release hydroxyproline under the action of lipase, so that collagen synthesis is promoted, elasticity is improved, and lip skin is plumped.

Sucrose fatty acid esters are nonionic surfactants with a hydrophilic sucrose group and a lipophilic fatty acid group, known as sugar esters; the hydrophilic sucrose moiety has a firm and compact structure and combines excellent hydrophilicity with high oleophobicity. Therefore, a firm interface film can be formed at the oil-water interface. Is prepared by transesterification of C12-18 fatty acid methyl ester (stearic acid, palmitic acid, oleic acid and lauric acid) and sucrose, and is natural and mild and does not contain polyethylene glycol. Sucrose esters can be used as emollients and moisturizers to achieve the moisturizing and moisturizing effects by forming a permeable sebum film similar to natural sebum on the skin surface; it hardly affects the natural sebum layer of the skin, and has the property of merging and increasing the natural sebum of the skin. Protecting sebum layer, helping to protect skin from dryness and losing elasticity, and ensuring defending function of skin. Sucrose esters do not affect the NMF (natural moisturizing factor) of the skin, but rather soften the skin, promote lubrication and provide a pleasant skin feel.

TABLE 9PRIMOS lip texture volume detection results

Measurement value: the lower the PRIMOS lip texture volume value, the smaller the lip texture volume.

The results demonstrate that there was no significant change in PRIMOS lip texture volume from the basal value (p ≡0.05) 5 minutes after single use of the example 1 sample by the subject; after 2 hours of use, the PRIMOS lip texture volume has no significant change (p is more than or equal to 0.05) compared with a basic value; the PRIMOS lip texture volume was significantly reduced (0.001. Ltoreq.p < 0.01) from the base value at a reduction of 10.39% using 24 hours. The PRIMOS lip texture volume was significantly reduced (0.001. Ltoreq.p < 0.01) from the base value over 3 days, at a reduction of 10.62%. Example 5 compares to example 1, with the results being close, with examples 2-4 being lower than examples 1, 5, and the comparative example being the lowest value.

TABLE 10PRIMOS lip texture quantity detection results

Measurement value: the lower the PRIMOS lip texture number value, the lower the lip texture number.

The results demonstrate that subjects used the example 1 sample for 5 minutes at a single time, the PRIMOS lip texture number was significantly reduced (p < 0.001) from the basal value, with a reduction rate of 33.68%; after 2 hours, the PRIMOS lip texture number was significantly reduced (p < 0.001) from the base value, with a 32.18% reduction; after 24 hours, the PRIMOS lip texture number was significantly reduced (p < 0.001) from the base value, with a reduction of 27.67%. After 3 days, the PRIMOS lip texture number was significantly reduced (p < 0.001) from the base value by 35.41%. Example 5 compares to example 1, with the results being close, with examples 2-4 being lower than examples 1, 5, and the comparative example being the lowest value.

Table 11 subject self-evaluation

For example sample 1, 93.94% of the subjects considered the product to have a clear and well absorbed texture, considered the lips to be more elastic after use, considered the lips to be fuller and plump after use, 96.97% of the subjects considered the product to have an effect of improving gloss on the lips, 87.88% of the subjects considered the product to have a clear improvement on the lips, and 100% of the subjects considered the product to be mild and not irritating. Example 5 was less clear, probably due to higher grease content, and other efficacy evaluations were similar to example 1, followed by examples 2-3, with lower efficacy than examples 1, 5, but better skin feel clarity, better comparative clarity, but lower other efficacy data.

The foregoing is merely exemplary embodiments of the present invention and are not intended to limit the scope of the present invention, and all equivalent modifications made by the present invention or direct or indirect application in the relevant art are intended to be included in the scope of the present invention.
