Description

[0001] The present invention relates to a cosmetic composition for lipint comprising a solid lipid particle,

The present invention relates to a cosmetic emulsifying composition comprising solid lipid macromolecules (SLM).

Solid lipid macro particles (SLM) or Solid Lipid Nanoparticles (SLN) are one of the colloidal delivery systems, and are excellent biocompatibility and stability nanoparticles. These nanoparticles contain cosmetics such as ceramides and vitamins Ingredients, and natural oils, etc., which are used in the cosmetics industry as a stabilizing system to enhance efficacy with a high interest in functional cosmetics.

Generally, the cosmetic composition for water-dispersible type lipsticks has a characteristic of being moist and moist due to the inclusion of water. However, due to the rapid evaporation of water, the moisture sensation disappears over time, giving a dry feeling, and the problem of deterioration of gloss as well as evaporation of water. In addition, in the case of the oil dispersion type, the moisturizing power is relatively improved, but it is sticky and has a problem of high oiliness. In the case of the emulsification type, there is a limit in that the spreadability is poor and the dispersion and emulsion stability are poor.

Therefore, it is necessary to introduce a cosmetic composition for lips which has the advantages of conventional water-dispersible and oil-dispersible type lipsticks at the same time, and thus has excellent moisture, moisturizing power and coloring power, and is easily cleansed while maintaining its sustainability.

In view of the above, a problem to be solved by the present invention is to provide a cosmetic composition for lips comprising solid lipid particles having excellent color sustainability.

In view of the above, a problem to be solved by the present invention is to provide a cosmetic composition for lips comprising solid lipid particles excellent in feeling of use.

In order to solve the above problems, the present invention provides a cosmetic composition for lips comprising solid lipid particles, wherein the solid lipid particle comprises a solid lipid carrier, and a liquid oil and a pigment carried on the carrier, .

From a point of view, the present invention can provide a feeling of use such as moisture, adhesion, coloring power, and the like in comparison with a conventional water dispersion, oil dispersion, or emulsified lignot composition.

In one aspect, the present invention can be easily cleansed while maintaining its durability relative to conventional water-dispersible, oil-dispersed, or emulsified lignot compositions.

[Preparation Example 1] Preparation of cosmetic composition for lip including solid lipid particles

After heating the oil part of Table 1 described above to 70 DEG C or higher, the red pigment base was added thereto, followed by agitation at 500 rpm and uniform dispersion.

The water part was warmed to about 55 to 60 DEG C, and the oil part was slowly added to the prepared water part, homomixed at a speed of about 5000 rpm, and then cooled. Thus, a cosmetic composition comprising solid lipid particles having liquid oil and red pigment carried therein was prepared.

Here, the behenyl alcohol is a saturated wax having a melting point of about 65-73 DEG C, and is a saturated higher alcohol having a carbon number of 22, which is aliquot purified from a reduced reducing alcohol. Since there is a hydroxyl group at the end of the saturated straight chain hydrocarbon chain, it is widely used for O / W and W / O type emulsions such as cetanol as an emulsion stabilization auxiliary.
