preparation example Construction

[0014] The average particle diameter of the liposomes involved in the nano-liposomes formed during the preparation of the water-soluble cosmetic composition of the present invention is 10-500 nm. The size of the nanoliposomes formed in the present invention is preferably 50-300 nm. When the average particle size of the nanoliposome is greater than 300nm, the technical effects obtained by the present invention including improving its permeability in the skin and the stability of the preparation are not significant.

[0015] In the present invention, the nanoliposomes formed for the stabilization of oleanolic acid are prepared from a mixture containing polyhydric alcohols, oily components, surfactants, phospholipids and water. Moreover, nanoliposomes encapsulating oleanolic acid in a soluble cosmetic composition are naturally formed during the preparation of the soluble cosmetic composition without high pressure emulsification or a separate preparation process.

[0025] Hereinafter, the present invention will be described in further detail with reference to examples and test examples. However, it should be understood that the following examples, test examples and preparation examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0026] Reference Example 1: Preparation of oleanolic acid-containing soluble cosmetic emulsion stabilized with nanoliposomes.

[0027] According to the compositions shown in Table 1 below, soluble wrinkle-reducing cosmetic emulsions of Examples 1-3 and Comparative Examples 1-4 were prepared.

[0028] The emulsions in Examples 1-3 are soluble cosmetic emulsions containing nanoliposomes formed according to the present invention, the emulsions in Comparative Examples 1 and 2 contain conventional solubilizers different from Examples 1-3, and Comparative Examples The emulsion in 3 contains a nanobase encapsulating oleanolic acid. The emulsion in Comparative ...

Abstract

The present invention relates to a solubilized cosmetic composition which uses an oleanolic acid entrapped in nano-liposomes as an active ingredient. The present invention can increase percutaneous absorption of an active ingredient using nano-liposomes to promote synthesis of collagen, thus providing a good anti-wrinkle effect. Also, since other additional raw materials are not used for capsulation, the manufacturing cost of a product can be reduced, and a good sensation during use can be provided.

Description

technical field [0001] The present invention relates to a soluble cosmetic composition containing oleanolic acid encapsulated in nanoliposomes as an active ingredient for reducing wrinkles. Background technique [0002] The skin is the main barrier of the human body. It protects organs from the effects of changes in temperature and humidity and damage from the external environment such as UV radiation or pollutants. It also plays an important role in maintaining homeostasis, for example: regulating body temperature. However, excessive chemical and physical stimulation, stress, malnutrition, etc. are not good for the normal function of the skin, and will accelerate the aging phenomenon of the skin, such as: loss of elasticity, keratinization and wrinkles. Cosmetics used to prevent these phenomena and maintain skin health and elasticity often have various problems, mainly such as insufficient efficacy or various problems causing skin side effects (Korean Patent Laid-Open Pub...
