Water-in-oil cosmetic composition with Shape-Memory Ability "

The present invention relates to a water-in-oil type cosmetic composition, and more particularly, to a cosmetic composition having shape memory ability by containing siloxane and silicone quaternary in a water-in-oil type water-in-oil type formulation.

Cosmetics companies have made great efforts to prevent and improve symptoms that interfere with people's pursuit of extrovert beauty, such as dryness, loss of elasticity, wrinkles, spots and freckles. Among the symptoms that interfere with the appearance beauty of the above people, wrinkle formation is typical. The first cause is genetic factors that are influenced by genes inherited from parents. The second cause is the movement of the muscles according to the facial expression. This occurs naturally when humans laugh or frown, and can result in wrinkles being created by constantly applying certain forces over time. The third cause is increased collagen and elastin, which account for the majority of skin dermis, and an increase in matrix metalloproteinase (MMP) that breaks down.

The main reason for the increase in the amount of MMP, which is the main cause of wrinkles and skin elasticity, is UV. Ironically, in the global atmosphere, consumers are always exposed to UV. Therefore, consumers' demand for functional cosmetics to prevent wrinkle formation and improve skin elasticity is increasing, and a large market has been formed all over the world. However, using existing functional cosmetics, wrinkles and skin elasticity to improve the effect of at least 3 months to use the product is visible only when the effect appears. But consumers are looking for products that can be more effective in the short term. Accordingly, there is a growing preference for cosmetics in which consumers can visually see immediate skin wrinkle improvement and immediate skin elasticity improvement.

Cosmetic compositions using Shape-Memory polymer have been developed as various categories of cosmetic products that show immediate skin wrinkle improvement and immediate skin elasticity improvement. In general, the cosmetic composition having shape memory ability imparts shape memory ability depending on the characteristics of the shape memory polymer which is a water-soluble thickener in an underwater type.

However, in the case of a cosmetic composition using a polymer having a shape memory ability, since it can be applied only to an underwater type, there is a problem that it has a low moisture-holding ability, and thus a shape memory ability is not given in a water- .

The inventors of the present invention have found that a cosmetic composition having shape memory ability can be produced by including siloxane and silicon quaternium, and completed the present invention.

To confirm the improvement of skin moisturizing ability, changes in water loss of the scalp were observed. Trans Epidermal Water Loss (TEWL) refers to the amount of water delivered from the body through the epidermal layer of the skin through the diffusion and evaporation process from the skin to the atmosphere, and is measured at 1 hour It is expressed in g / m ² h value, which is the amount of moisture (g) that evaporates. Before the use of the cosmetic preparation of Formulation Example 1 and the cosmetic preparation of Formulation Example 1 were applied daily to the facial ball area, the amount of water loss was measured by using a water vapor transmission system (Vapometer, Delfin Technologies Ltd, Finland) The amount of water loss in the scalp area was measured.

The measured values of the light-to-surface moisture loss of Formulation Example 1 were 6.24% at 17.02 ± 3.91 g / m ² h before use and 16.02 ± 3.86 g / m ² h after 2 weeks of use. The P value of the value was less than 0.05 after 2 weeks of use when tested by the parametric method Paired samples t-test according to the normality test. A P-value of less than 0.05 implies less than 5% chance of a 6% decrease in gloss naturally in the untreated group.

Therefore, it was confirmed through the above experimental results that Formulation Example 1 lowered the water loss rate of the skin and improved the skin moisturizing power.

Test Example  5: Shape memory Cosmetics  Confirmation of skin luster improvement effect of composition formulation

In order to confirm the skin luster improvement effect of the above-mentioned Formulation 1, clinical tests were conducted on 22 women aged 19 to 55 years. To confirm the effect of improving the glossiness, the skin gloss unit (SGU) value before use of the cosmetic preparation of Formulation Example 1 and the cosmetic preparation of Formulation Example 1 was applied to the face ball area twice daily was used for skin gloss meter , Delfin Technologies Ltd, Finland).

The skin gloss measurement value of Formulation Example 1 was increased from 63.03 ± 6.20 before use to 64.44 ± 6.06 after 2 weeks of use, and was 2.24% increased by 2.24% when using Paired samples t-test, which was a parametric method according to regularity test. The P-value of the value was less than 0.05. A P-value of less than 0.05 implies less than 5% chance of a natural 2% increase in gloss in an untreated experimental group.

 Therefore, it was confirmed from the above test results that Formulation Example 1 improves skin glossiness through statistical results.
