Description

Lip protecting ointment for softening lip cutin and improving lip state and preparation method thereof

Technical Field

The invention belongs to the technical field of cosmetics, and particularly relates to lip protecting ointment for softening lip cutin and improving lip state and a preparation method thereof.

Background

In the field of lip care, products such as lip gloss, lip sleeping masks, lip cream, lip scrub, lip sunscreen, and the like, in addition to the most basic lip gloss, come to the consumers, and the development of lip care products has been increasingly diversified. The lip scrub is one of products having a function of removing the horny layer of lips, sucrose particles with different particle sizes, nut shell powder such as walnut powder and the like are often used as an abrasive, but obvious friction feeling exists in the exfoliating process, sensitive lips feel obvious pain feeling, the use feeling of the product is poor, and the potential possibility of scratching the skin is high.

The prior related art discloses a lip scrub and a preparation method thereof, which comprises 50-60 wt% of sucrose, 30-60 wt% of petrolatum, 3-8 wt% of tridecyl alcohol trimellitate, 4-6 wt% of hydrogenated castor oil, 0.3-0.6 wt% of preservative and 0.2-0.3 wt% of aromatic. The prepared lip scrub cream has good smearing property, and can effectively remove aged cutin and dead skin. But the sucrose content is extremely high, obvious friction feeling can be felt in the using process, and the potential of scratching the skin is realized.

The prior related art discloses a lip scrub cream and a preparation method thereof, and the lip scrub cream comprises 1-20 parts of macadamia nut shell powder, 1-30 parts of cane sugar, 1-10 parts of honey, 1-10 parts of royal jelly, 1-5 parts of allantoin, 1-5 parts of hydrogenated castor oil, 1-25 parts of natural vegetable oil, 1-25 parts of natural wax and 1-5 parts of a preservative. According to the invention, macadamia shell and sucrose are used as an abrasive, the macadamia shell has high hardness and an adsorption function to remove lip cutin, and honey, royal jelly, natural vegetable oil and natural wax reduce damage caused by friction. Although the invention is designed to reduce the damage caused by friction through honey, royal jelly, natural vegetable oil and natural wax, the crystal irregularity of the friction agent still gives the potential possibility of scratching the skin and the uncomfortable feeling during use.

In conclusion, for the treatment of the cutin of the lip skin, the cutin of most products is directly removed in a physical friction mode, the rubbing discomfort exists in the process, the cutin needs to be removed by clean water after use, the injury to the lip skin is caused by secondary friction such as paper towel cleaning and the like, and the potential possibility of scratching deep skin is caused by physical friction. Therefore, there is a need to develop a lip care product that can prevent skin from being scratched, soften cutin, and make the aged cutin of lips naturally fall off, thereby achieving the purpose of improving the state of lips.

Disclosure of Invention

The present invention is directed to solving at least one of the problems of the prior art described above. Therefore, the invention provides lip protecting ointment for softening lip cutin and improving lip state and a preparation method thereof.

The first aspect of the present invention provides a lip care ointment for softening the cutin of lips and improving the condition of lips, which comprises the following components: urea, shea butter, glyceryl stearate, behenyl alcohol, palmitic acid, stearic acid, myristyl alcohol, lecithin, lauryl alcohol and cetyl alcohol.

It is to be noted that, the components of the present invention: glyceryl stearate, behenyl alcohol, palmitic acid, stearic acid, myristyl alcohol, lecithin, lauryl alcohol and cetyl alcohol are available from the Ashland group under the product model prolipid 141.

The lip protecting mechanism of the lip protecting ointment is as follows:

urea increases the water content of the stratum corneum of the skin, softens the stratum corneum, swells it, and changes the permeability and activity coefficients of the osmotically active ingredient, thereby promoting penetration of the active ingredient.

The main component of prolipid 141 is a plant-derived oil-water amphiphilic molecular structure, and the dosage is carefully balanced to form a stable layered gel phase system of bionic lipid. Ordered layered structures are crucial for building strong barrier protection and optimal hydration. The lipid membrane can be provided on the upper layer of the horny layer to form a water-locking layer which greatly reduces the water loss, thereby accelerating the skin repairing process; the ability of prolipid 141 to rapidly and effectively increase skin hydration is reflected by changes in skin conductance.

The shea butter is rich in saturated fatty acid and unsaturated fatty acid, and the unsaturated fatty acid has a certain transdermal penetration promoting effect. The fatty acid compound has a structure similar to that of fatty acid in skin, unsaturated double bonds exist in the molecule to enable the fatty acid compound to have an asymmetric spatial structure, when the fatty acid molecule is inserted into a lipid bimolecular hydrophobic structure of stratum corneum lipid, due to the cis-structure of the unsaturated hydrophobic chains, the bimolecular layer is twisted to form a fine flow channel easy to permeate, the ordered arrangement of the stratum corneum lipid structure is effectively influenced, and therefore the percutaneous absorption of active ingredients is promoted. The shea butter is easy to be melted on the skin when being smeared on the skin, and a thin oil film is formed on the surface to moisten and soften the skin.

The lip care ointment disclosed by the invention has a synergistic effect by compounding the urea, the shea butter and prolipid 141 (glyceryl stearate, behenyl alcohol, palmitic acid, stearic acid, myristyl alcohol, lecithin, lauryl alcohol and cetyl alcohol), and can soften the cutin of lips and improve the state of the lips. The lip protecting ointment avoids potential damage and discomfort caused by the traditional lip cutin treatment mode of removing cutin by adding ground particles such as sucrose particles and nut shell powder.

Test example 3 evaluation of sensory Effect of consumers

3.1 test subject

40 volunteers aged between 20-50 years, who were frequently using lip makeup and had lips dry to a dry and cracked condition after makeup removal, were selected as subjects.

3.2 test specimens

Examples 1-6, comparative examples 1-6, a commercially available lip exfoliating scrub, for a total of 13 test samples.

3.3 test methods:

since the subjects were repeatedly participating in the experiment, the development of the corresponding test experiment for each group of test samples was performed at intervals of at least 7 days. The test experiment of example 1 was carried out as day 1, and the test experiment of example 2 was not carried out until day 8.

The test sample is applied to the test sample 1 time after the makeup removing liquid and the makeup removing cotton are used for removing the makeup at night and before the test, if the test sample is not applied to the lips on the same day, the test sample is used after the lips are wiped by the makeup removing liquid and the makeup removing cotton, the test sample is kept on the lips for 8 hours, and the state of the lips after getting up in the morning on the next day is observed and recorded.

3.4 Effect evaluation method

After the end of use, the subjects evaluated the effects of softening keratin before and after the use of the samples, improving the state of lips, and the evaluation results were classified into three grades, i.e., better, general, and no effects.

3.5 evaluation results

The results are shown in Table 16:

TABLE 16

3.6 analysis of results

As can be seen from Table 16, examples 1-6 all significantly softened the cutin and improved the dry-crack condition of the lips in a shorter period of time, and examples 1-6 all tested better than comparative examples 1-5 and also better than some commercially available lip exfoliating scrub.

Comparing example 1 with comparative example 1, comparing example 1 with comparative example 2, comparing example 6 with comparative example 5, the three groups of comparison experiments show that the combination of urea, shea butter and Prolipid 141 (glyceryl stearate, behenyl alcohol, palmitic acid, stearic acid, myristyl alcohol, lecithin, lauryl alcohol and cetyl alcohol) has obvious synergistic effect, and the effect is better than that of the combination of two.

Comparing example 1 with comparative example 3, it was revealed that the addition of urea, shea butter and Prolipid 141 (glyceryl stearate, behenyl alcohol, palmitic acid, stearic acid, myristyl alcohol, lecithin, lauryl alcohol and cetyl alcohol) of the present invention softened cutin and improved the state of lips significantly more than comparative example 3 without the addition of these components.

Comparing example 1 with comparative example 6, and analyzing the results of comparative example 1, it is shown that the compatibility of the components of Prolipid 141 provided by Ashland corporation is unique and synergistic, and that simply mixing known individual components does not achieve the desired efficacy.

Comparing example 3 with comparative example 4, it is shown that the system compounded by urea, shea butter and Prolipid 141 (glyceryl stearate, behenyl alcohol, palmitic acid, stearic acid, myristyl alcohol, lecithin, lauryl alcohol and cetyl alcohol) of the present invention has better effect of improving the dry state of lips than the system added with urea alone.

In addition, through subject feedback, we also found that examples 1-6 maintained the lips from drying for longer periods of time. Also, in comparative example 2, it was found that there was a remarkable effect of softening keratin, but the effect of moisturizing lips was inferior to those of examples 1 to 6.

While the preferred embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that the present invention is not limited to the details of the embodiments shown and described, but is capable of numerous equivalents and substitutions without departing from the spirit of the invention as set forth in the claims appended hereto.
