preparation example Construction

[0033] Specifically, the preparation method of emulsified cosmetic composition without emulsifier comprises: the step of preparing the water phase part comprising polyol, sweet orange tree dietary fiber and water; preparing the oil phase part by mixing oil and dipalmitoyl hydroxyproline steps; a step of adding and mixing the above-mentioned oil phase part to the above-mentioned water phase part; and a step of cooling.

[0034] Each step is described in detail below.

[0035] First, an aqueous phase containing polyhydric alcohol, orange tree dietary fiber, and water was prepared.

[0036] At this time, dissolve in a vacuum emulsification tank that can adjust the temperature and can be stirred by a conventional method, and heat at a temperature of 50°C to 80°C, preferably at a temperature of 60°C to 75°C to make other ingredients fully Dissolve in water.

[0037] Next, mix oil and dipalmitoyl hydroxyproline to prepare the oil phase. At this time, other components are fully diss...

[0056] Experimental example 2: Improvement effect of skin wrinkles

[0057] In order to evaluate the wrinkle-improving effect of the composition of Example 1 prepared above, the skin wrinkle-improving effect was measured as follows on the skin to which cosmetics were applied. The above-mentioned measurement is after the temperature of 20 ℃~24 ℃ and the relative humidity are 45%~55% under constant temperature and humidity conditions for 20 minutes, the composition of embodiment 1 is applied to the skin of the test subject, and the product is used The changes were evaluated before and after 4 weeks of using the product.

[0058] At this time, skin wrinkles around the eyes were measured using a blue light skin three-dimensional scanner (Dermatop-blue, EO tech, France), and the improvement effect obtained by using the samples was analyzed using dedicated software. The above-mentioned blue light skin three-dimensional scanner (Dermatop-blue, EO tech, France) is a machine for measu...

Abstract

The present invention relates to an emulsifier-free emulsion cosmetic composition and, more specifically, to an emulsifier-free emulsion cosmetic composition comprising dipalmitoyl hydroxyproline and Citrus Aurantium Sinensis Fiber as active ingredients. The emulsifier-free emulsion cosmetic composition blocks skin irritation provocation and allergy onset problems since the composition does not contain an emulsifier, unlike a general emulsion system, and can secure a high value as a cosmetic since the composition maintains emulsion stability and at the same time has a skin-improving effect, even though the composition does not contain an emulsifier.

Description

technical field [0001] The present invention relates to an emulsifier-free emulsified cosmetic composition capable of maintaining emulsion stability without including an emulsifier and having an effect of improving skin. Background technique [0002] Cosmetics are used to protect, restore and maintain skin health from the external environment. Moreover, it has the function of replenishing skin moisture and oil lost in the process of washing the face every day and delaying skin aging. [0003] In the emulsification process for preparing such multifunctional cosmetics, it is necessary to use an emulsifier to uniformly disperse the particles so that the water-phase liquid particles and the oil-phase liquid particles do not aggregate. When the above-mentioned emulsifier is included in the above-mentioned emulsification process as a molecule having both a hydrophilic part and an lipophilic part, it exerts a function of lowering the surface tension between the water phase and the...
