Description

[0001] The present invention relates to a cosmetic composition having an instant transparency shift,

The present invention relates to a cosmetic composition capable of imparting sensory differentiation by changing the apparently opaque appearance of the cosmetic composition by instantaneously decreasing the particle size by mixing the components 1 and 2 separated in the container.

In the cosmetics industry, the use of high-quality raw materials and the emphasis on pure and natural images are stimulating users to buy. In the case of cosmetic ingredients, water-soluble ingredients, oil-soluble ingredients, powders and active ingredients are mixed to maintain skin moisturization, protection, and skin health, and about 10 to 50 kinds of raw materials are used to produce one product.

In particular, the cosmetics industry is a highly competitive industry, with as many competitors as there are, and with this growth, suppliers or manufacturers need to express their product characteristics clearly.

The recent development of cosmetics is characterized by the development and introduction of ingredients that give a distinctive appearance or differentiated feeling different from the existing ones and instantly feel instantly as soon as they are applied to the skin. In addition, the appearance and feel of the product, as well as the sensory fun, play a crucial role in the consumer's choice of product to purchase.

For example, Korean Patent Laid-Open Publication No. 2006-0113050 proposes a cosmetic composition having a formulation similar to fresh cream, and mentions that such a composition can provide consumers with a new and enjoyable consumption experience.

Korean Patent Laid-Open Publication No. 2007-0106115 proposes a washable cleansing cosmetic composition having elasticity, and the composition can be easily rinsed with water after use without irritation to the skin, and has elasticity so that it can provide sensual fun in appearance Lt; / RTI >

Korean Patent No. 10-0869155 discloses an emulsion type cleanser which combines the merits of cleansing oil and cleansing water as a unique and distinctive formulation and visually has a two-layer structure.

FIG. 4 shows the particle size in the preparation 1 and the result of measuring the particle size change in the whole cosmetic composition when mixed with the preparation 2.

Hereinafter, the present invention will be described in more detail.

In the present invention, a cosmetic composition is provided which is capable of imparting sensory differentiation by changing the apparently opaque appearance of the cosmetic composition by instantly decreasing the particle size while mixing the ingredients 1 and 2 separated in the container.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a photograph showing instantaneous changes in transparency of a cosmetic composition in which transparency changes according to an embodiment of the present invention; FIG.

Referring to FIG. 1, the first agent and the second agent are separated in a container, and the agent is opaque. As the consumer opens the structure that separated the first agent and the second agent in use, the first agent and the second agent are mixed and the opaque agent is mixed with the second agent and changed into a transparent appearance.

In order to induce such instantaneous transparency change, the critical micelle concentration (CMC) of the surfactant is used in the present invention.

Conventional surfactants exist in the form of molecules in the aqueous solution, but when the concentration of the surfactant in the solution increases, the surface tension is lowered, and when the surface tension is no longer lowered, the association of the hydrophobic groups of the surfactant And the hydrophilic group is formed into a micelle, which is an aggregate having a structure that is directed outward so that the hydrophilic group can come into contact with water. Thus, the concentration of the surfactant solution that forms the micelle is called the critical micelle concentration (CMC). The physical properties such as interfacial tension, surface tension, electrical conductivity, cleaning ability, and viscosity of the surfactant solution change rapidly around this critical micelle concentration. For example, a third substance that is not dissolved in a surfactant solution has a property of dissolving in micelles at a critical micelle concentration or higher, which is called solubilization.

FIG. 2 schematically shows changes in transparency of the cosmetic composition depending on whether micelles are formed in the surfactant before or after the critical micelle concentration.

As shown in FIG. 2, when the surfactant is contained in a concentration lower than the critical micelle concentration, the surfactant is present in the form of a molecule in the aqueous solution, and the oil particle size is several hundred nm or more, and the cosmetic composition is opaque. When a surfactant is included, the micelle size of the surfactant in the aqueous solution is rapidly reduced to less than several tens of nanometers, resulting in a transparent state.

For the change before and after the critical micelle concentration, the cosmetic composition according to the present invention is separated into a container containing a first surfactant and a second surfactant, wherein the first surfactant has a critical micelle concentration And the total amount of the first surfactant and the second surfactant in the mixture of the first agent and the second agent is greater than the critical micelle concentration in the entire cosmetic composition .

The mixing of one agent and two agents is the case where the physical force is applied not only to the case where the external force is applied but to the separated case where the external force is not applied but also when the container is shaken, .

Here, the first surfactant and the second surfactant may be the same or different.

The agent mixed with the agent may be in a transparent or opaque state.

The first surfactant and the second surfactant preferably have a hydrophilic lipophilic balance (HLB) of 8 or more, preferably 10 to 15, for stability of the formulation and rapid change of transparency in an aqueous solution.

More preferably, the first surfactant and the second surfactant are polyglyceryl-2 caprate, polyglyceryl-2 caprylate, polyglyceryl-3 caprate, polyglyceryl-3 caprylate, polyethylene Caprylic / capric glycerides, polyethylene glycol-6-caprylic / capric glycerides, polyethylene glycol-7-caprylic / capric glycerides, polyethylene glycol-8-caprylic / Polyethylene glycols - 100 Hydrogenetite Castor Oil, Polyethylene Glycol - 100 Hydrogenetite Castor Oil, Polyethylene Glycol - 60 Hydrogenetite Castor Oil, and Polyethylene Glycol - 40 Hydrogenetite Castor Oil Water ≪ / RTI >

For example, the first surfactant and the second surfactant may be the same as or different from each other as polyglyceryl-2 caprate, polyglyceryl-2 caprylate, polyglyceryl-3 caprate or polyglyceryl-3 caprylate , The first surfactant is contained in less than 2% by weight of the first cosmetic composition so that the cosmetic composition satisfies 100% by weight of the total amount of the first surfactant and the second surfactant The second surfactant may be included in the second agent so that the sum of the contents exceeds 2% by weight.

In another example, the first surfactant and the second surfactant are the same as each other, such as polyethylene glycol-4-caprylic / capric glyceride, polyethylene glycol-6-caprylic / capric glyceride, polyethylene glycol- Wherein the first surfactant is contained in an amount of less than 1% by weight so that the cosmetic composition satisfies 100% by weight of the total amount of the cosmetic composition, when the composition is polyacrylic / polyacrylic / caprylic / caprylic / The total amount of the first surfactant and the second surfactant in the total cosmetic composition when the first agent and the second agent are mixed may be more than 1 wt%, and the second surfactant may be included in the second agent.

As another example, the first surfactant and the second surfactant may be the same as each other, such as polyethylene glycol-200 hydrogenetite castor oil, polyethylene glycol-100 hydrogenogenide castor oil, polyethylene glycol-60 hydrogenogenide castor oil, or polyethylene Glycol hydrohalogenide castor oil water, and the first surfactant is contained in an amount of less than 0.01% by weight so that the cosmetic composition satisfies 100% by weight of the total amount. When the surfactant is mixed with the first and second agents, The sum of the contents of the first surfactant and the second surfactant may be greater than 0.01% by weight, and the second surfactant may be contained in the second agent.

When the first surfactant and the second surfactant are different, the first surfactant may be polyethylene glycol-4-caprylic / capric glyceride, polyethylene glycol-6-caprylic / capric glyceride, polyethylene Caprylic / capric glyceride, or polyethylene glycol-8-caprylic / capric glyceride, and the second surfactant is polyethylene glycol-200 hydrogenide castor oil, polyethylene glycol-100 Hydrogenetite castor oil or a polyethylene glycol - 40 hydrogencarbonate castor oil water, and wherein the first surfactant comprises less than 1% by weight of the first surfactant so that the cosmetic composition comprises 100% , And when the first agent and the second agent are mixed, the total amount of the first surfactant and the second surfactant The sum of the amount of a second surface active agent can be included in the claim 2 is at least 0.3% by weight.

The first agent comprises a first surfactant, a polyol and purified water, and the second agent comprises a second surfactant, a polyol and purified water.

Wherein the polyol is selected from the group consisting of glycerin, 1,3-propylene glycol, butylene glycol, dipropylene glycol, glycerin, erythritol, xylitol, maltitol glycerin, sorbitol, polyglycerin, polyethylene glycol, pentanediol, isoprene glycol, And combinations thereof.

When the content of the first surfactant and the second surfactant was 1% or more, which is the critical micelle concentration or more, the first and second surfactants were transparent and had a particle size of about 10 nm, as in Examples 1 to 3.

That is, as shown in FIG. 4, when the first surfactant is contained in less than the critical micelle concentration in the first agent, the particle size is opaque at about 1300 nm. However, when the first surfactant and the second surfactant The total particle size was reduced to about 1/130 due to formation of the critical micelle concentration or more.

On the other hand, even if the first agent and the second agent are mixed as in Comparative Examples 1 and 2, the formulation is opaque when the sum of the contents of the first surfactant and the second surfactant is less than the critical micelle concentration and the particle size is not reduced.

In Comparative Example 3 in which the first surfactant and the second surfactant were different from each other, the formulation containing 0.01 wt% of the critical micelle concentration of the polyethylene glycol-200 hydrogenc ... . As in Examples 4 and 5, the concentration was higher than 0.01 wt%, which is the critical micelle concentration of polyethylene glycol-200 hydrogenated castor oil alone. When the polyethylene glycol-6 caprylic / capric glyceride alone was used, It is believed that the critical micelle concentration is formed at a concentration lower than 1 wt%.

In order to confirm the degree of mixing of the 1st agent and the 2nd agent in the case of using the incremental zero polymer, 1 and 2 agents were prepared with the compositions shown in Table 4 below, and the degree of mixing required for changing the transparency was confirmed.

Spontaneous mixing was not observed when the polymers of Examples 7 to 10 were used, but the mixing was easy even with slight shaking, and the appearance was transparent. However, as in Comparative Examples 4 and 5, when the polymer is used in an amount of 2% by weight or more, the viscosity of the polymer is high and it can be confirmed that the first and second polymers are not easily mixed physically.
