Description

Process for preparing color change soft emulsion beads containing pearl pigment

The present invention relates to a method for producing a color change soft emulsion beads containing a pearl pigment, and more particularly, to a method for producing a color change soft emulsion beads containing a pearl pigment produced in a liquid emulsion and the color change produced by Soft emulsion beads.

Recently, the cosmetics market has formed a large customer base not only for women over 20, but also for middle and high school students and men. In particular, there are many customers who have dark skin tones or burden complex skin care steps such as skins, essences, lotions, creams and sunscreens. The demand for "elastic essence" or "elastic cream" is increasing rapidly. In line with this situation, some products have been developed that can give a glow feeling and have a tone correction effect. However, most of these active ingredients are highly unstable with heat, light, temperature, moisture, oxygen, and time. Efforts have been made to encapsulate the active ingredient and to increase the stability of the active ingredient using moisturizers and various stabilizers.

In addition, in order to reflect the recent cosmetic market trends of fun and emotion, attempts to provide users with visual pleasure, aesthetic sensibility and makeup pleasure by modifying the unique form, color and / or texture of the emulsion formulation are have. Korean Patent No. 10-0144371 (registered on April 17, 1998) prepares an aqueous phase containing ethanol and water and an oil phase containing digested polyisobutene, pearl powder and jojoba oil, respectively. A fragrance lasting cosmetic containing a pearlescent flowable beads completely dispersed in an oil phase is disclosed. However, as disclosed in the patent document, the pearlescent fluid beads have almost no cosmetic role, but merely serve to modify the appearance of the cosmetic including the same. In addition, Korean Patent No. 10-1553233 (registered on September 9, 2015) maintains a liquid emulsion which may include a solution containing a lipid or gel-forming substance which is a solid at a room temperature at a temperature below 0 ° C. Disclosed is a method for preparing solid bead emulsion beads by dropwise addition to a freeze refrigerant.

From this, in the present invention, there is a need to develop a product which can be applied to a pearl pigment exhibiting color by improving cosmetic formulation technology or developing new formulation technology.

(2) Oil solubilizer: phyto horse oil, CEH oil, HCO-40, ethylhexylglycerine (SENSIVA SC 50)

First, the raw materials were weighed to the contents shown in Table 1 in a microbalance, and the primary dispersion was carried out using a main mixer while sequentially adding the components corresponding to the water phase except the pearl pigment. After the mixture was completely dispersed, a pearl pigment (Sharon Fine Violet 7601D) was added to perform secondary dispersion using a main mixer. The uniformly dispersed water-dissolving tank was introduced into a heater, then heated to 95 ° C. to completely dissolve it, and then transferred to a main mixer and cooled to 75-80 ° C. with stirring. Next, the raw material corresponding to the oil phase was heated and dissolved at 70 to 75 ° C, and then transferred to the main mixer while maintaining the temperature at 68 to 70 ° C.

The oil phase of 68-70 degreeC was slowly thrown into the water phase cooled and dispersed to 75-80 degreeC, and emulsification was performed.

The viscosity was measured while maintaining the temperature of the prepared emulsion at approximately 70 ℃. The particle size of the beads according to the viscosity is less than 3 mm for 500 to 1000 cps, 3 to 4 mm for 1500 to 2500 cps, and 6 to 8 mm for 800 to 2000 cps. Prepared by adjusting the factor. The viscosity of the emulsion was dropped drop by drop onto a dropping medium (silicone oil) maintained at 10-20 ° C. through the nozzle tip, and beads formed by surface tension were cooled and discharged while circulating. Emulsion beads were obtained. The round shaped emulsion beads obtained had a size of approximately 2.5 to 3.5 mm and the weight composition of Table 1 above. The photograph of the obtained product is shown in FIG.

The obtained emulsion beads can be used directly as a liquid emulsion by rubbing on the skin by hand and not leaving any foreign substance or feeling of foreign substances, and with an immediate color development effect on the skin with a visual effect of changing the color of the beads Tone correction function is shown (see FIG. 2). It contains phyto horse oil and showed high moisturizing effect on the skin, and it showed a very soft feeling by adjusting the proper mixing ratio of agar which is a hardening agent, carrageenan which is a cracking and antispasing agent, and lipoid and HCO-40 as an emulsion stabilizer. . An example applied to the skin care cosmetic product using the emulsion beads is shown in FIG. 3.
