However, if this renewal becomes slow due to internal and external factors (including aging, stress, ultraviolet rays, and environmental pollution), excess keratin will accumulate and not be shed off, resulting in thickened skin and dark pigmentation. darkened skin
Also, this can lead to the formation of acne and wrinkles

preparation example 1

[0029] Preparation Example 1: Dissolved Ceramide Material

[0030] A dissolved ceramide material is prepared by combining purified water, emulsifier, solubilizer, and ceramide. Here, the ceramide is dissolved in an amount of 3-5% by weight.

preparation example 2

[0031] Preparation Example 2: Encapsulated Ceramide Material

[0032]Lipid technology is the key to developing cosmetic products that coordinate with skin functions. Preparation of different encapsulation materials through precise mimicry of liposome structure in skin and efficient supply of active ingredients. Using multilayer coating process (multilayer coating process) and fluidized bed technique (fluidized bed technique), at the same time to obtain the intercellular sheet and liposome envelope (lipid envelopes).

[0033] The encapsulated ceramide material composed of ceramide, lecithin and fatty acid is prepared by a multi-layer coating process and added in the final process after emulsification of the formulation. The stabilization and softening process of the capsules (3 h at 45 °C) was performed to reduce the foreign body sensation of the encapsulated ceramide material. A softening process is performed in order to reduce the impurity content of the capsules and allow ...

Embodiment 1 and 2 and comparative example 1-3

[0035] According to the ingredients and contents shown in Table 1 below, the formulations of Examples 1 and 2 and Comparative Examples 1-3 were prepared (unit: weight %). In Table 1, the ceramide amino acid derivative is phytosterol / behenyl alcohol / octyldecyl lauroyl glutamate (CAS No. 245443-09-8; purchased from Ajinomoto Co., Ltd.).

Abstract

The present invention relates to a water-in-oil type cosmetic composition, which improves the skin to be smooth and keeps the skin free from troubles, and more particularly to a water-in-oil cosmetic composition which has a short-term skin improvement effect, caused by a ceramide-like amino acid derivative and a stabilized papain enzyme, and a long-term skin improvement effect caused by a polysaccharide having a prebiotic effect of selectively controlling bacteria.

Description

technical field [0001] The present invention relates to a water-in-oil type cosmetic composition that improves skin to become smooth and prevents skin troubles, and more particularly relates to a composition having a ceramide-like amino acid derivative and a stabilized A water-in-oil cosmetic composition with short-term skin improvement effect produced by stabilized papain enzyme and long-term skin improvement effect produced by polysaccharide with selective control of bacteria. Background technique [0002] The stratum corneum is the outermost layer of the skin and is made up of dead cells. Healthy skin has a renewal cycle of around 28 days, during which old keratin is shed and a new layer of cells is formed. However, if this renewal becomes slow due to internal and external factors (including aging, stress, ultraviolet rays, and environmental pollution), excess keratin will accumulate and not be shed off, resulting in thickened skin and dark pigmentation. The skin turns ...
