Manufacturing method of oil-in-water type foundation composition showing shape-memory phenomenon

The present invention relates to an oil-in-water foundation composition and a method for preparing the same, and more specifically, to water-in-water thickener, Fiji-240 / H diidia copolymer bis-decyltetradeces-20 ether, based on the total weight of the composition An oil-in-water foundation composition containing 3% by weight and exhibiting a shape memory phenomenon when applied to the skin, and a method for producing the same.

Foundation compositions are makeup compositions for human skin. Foundation compositions are commonly used to mask skin defects such as redness and spots, as well as giving beautiful colors to the skin, especially the face. Foundation is a cosmetic that is used on the entire face, and it is an important factor to feel and maintain.

In general, foundations are divided into powder foundations, dispersed foundations and emulsion foundations, depending on the formulation. Among them, emulsified foundations have a medium covering power and contain a large amount of moisture, which is advantageous in terms of skin-friendlyness, has an advantage of excellent adhesion and durability, and is advantageous in containing various nutrients.

In detail, the emulsion type is an emulsification by dispersing a pigment in an aqueous phase or an oil phase, and then applying an oil phase or an aqueous phase, and an oil-in-water type having a pigment and an oil component in the aqueous phase and a water-in-oil type incorporating the pigment and an aqueous phase in the oil phase. It is classified by type. The oil-in-water foundation has the advantage of being lighter in use than the water-in-oil type, since the external composition is composed of aqueous components, but it has the disadvantage of weakness of color and sustainability over time. On the contrary, the oil-in-water type has better adhesion and sustainability than oil-in-water type, This feels heavy and frustrating to use.

The present invention was developed to secure the disadvantages of the above-mentioned color maintenance and weakness in the oil-in-water type of the oil-based foundation. In addition, the shape memory polymer was used as a thickener in water to give an effect on wrinkle improvement when applied to the skin. Here, the shape memory polymer is defined as a material that has the ability to memorize the shape appearing with the naked eye and relaxes the original stress by the specific temperature and the external physical force. A technology related to a cosmetic composition (Korean Patent Publication No. 1990-0005951 and Korean Patent Registration No. 10-0588831) containing such a shape memory polymer is disclosed.

To provide a water-based foundation composition and a method for producing the oil-in-water foundation that has a smooth color retention and persistence over time and has the effect of pulling out the skin due to the shape memory phenomenon when applied to the skin by applying a constant ratio as a reference, and smooth over time have.

In order to solve the above object, the present invention is a water-soluble thickener, and it is an oily bis-240 / H dii copolymer copolymer bis-decyl tetradeces-20 ether (PEG-240 / HDI) which generates elasticity when applied to the skin. COPOLYMER BIS-DECYLTETRADECETH-20 ETHER) to provide an oil-in-water foundation composition containing 1.5 to 2.5% by weight based on the total weight of the composition and exhibits a shape memory phenomenon when applied to the skin.

Hereinafter, the present invention will be described in detail by way of examples.

Example  1 to 5, and Comparative Example  1 to 4

The oil-in-water foundation compositions of Examples 1 to 5 and Comparative Examples 1 to 4 were prepared using the raw materials and contents shown in Table 1 below.

Specifically, the raw materials 1 and 2 shown in Table 1 were dispersed and pulverized with a three-stage roller, and then the raw material 3 was added and warmed up to 80 ° C. Stirring at 5000 rpm for 5 minutes using an AGI MIXER (Matsushita Electric Industial Co. Ltd, SER No 515, Japan) while slowly adding raw material 4 to the obtained mixture while maintaining at 80 ° C. (See FIG. 3). Next, raw materials 5 to 8 were mixed and these mixtures were warmed up to 80 ° C. Then, the mixture of raw materials 5-8 was put into the mixture of raw materials 1-4, and it stirred at 5000 rpm for 5 minutes using the HOMO MIXER, maintaining 80 degreeC. After cooling the obtained product to 50 ° C., the raw material 9 was added and stirred for 2 minutes at 3000 rpm using a homo mixer. Thereafter, the obtained final product was degassed for 2 minutes, filtered and mixed with natural cooling until it reached room temperature.

Example  And Comparative example  evaluation

20 females of 20 to 30 years of age in order to comprehensively evaluate the formation ability, softness, persistence and all of the oil-in-water foundation composition of Examples 1 to 5, and Comparative Examples 1 to 4 prepared by the above method Comparative evaluation was made and these average values are summarized in Table 2 below.

Test Items Example 1 Example 2 Example 3 Example 4 Example 5 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Memory formation ability 2.3 3.4 3.9 4.5 4.8 One 1.4 4.8 5 Persistence 3.1 3.8 4 4.4 4.9 1.4 1.9 4.9 4.9 Softness 4.2 4 3.9 3.5 2.4 3.8 3.7 1.8 1.2 Overall assessment 3.2 3.4 4.6 4 3.7 1.9 2.5 2.8 2.4 Very bad: 1, Bad: 2, Moderate: 3,

As shown in Table 2, it can be seen that the compositions of Examples 1 to 5 prepared according to the present invention have superior formation memory capability and persistence compared to those of Comparative Examples 1 and 2. However, in the compositions of Comparative Examples 3 and 4, formation memory capacity and persistence were somewhat reduced by using Fiji-240 / H-Didia copolymer copolymer bis-decyl tetradeces-20 ether in excess of 5% by weight based on the total weight of the composition. It was excellent, but the problem was not so soft because of its excessively thickening effect. On the other hand, in Comparative Examples 1 and 2, the use of Fiji-240 / H-Didia copolymer copolymer bis-decyl tetradeces-20 ether is 0.5% by weight or less based on the total weight of the composition, thereby forming a soft feeling upon skin contact but forming. Problems with weak memory and persistence were seen. Thus, for the compositions of Examples 1-5 comprising 1.0-3.0% by weight of Fiji-240 / H-Didia copolymer copolymer bis-decyltetradeces-20 ether, based on the total weight of the composition, formation softness as well as persistence as well as softness It can be seen that at the same time have a high score in the comprehensive evaluation.
