Description

Composition for increasing hardness of O/W cosmetics comprising polyol}

Disclosed herein is a composition for increasing the hardness of O/W cosmetics containing polyol as an active ingredient, an O/W cosmetic containing the same, and a method for increasing the hardness of O/W cosmetics.

Polyols and oils, especially polyols, are essential raw materials for making skin care products. In general, polyols are prescribed for their moisturizing function. The skin moisture level showed a strong correlation with polyols, and showed a strong correlation until the 20% concentration was treated. This correlation coefficient was statistically 0.629, showing a significant correlation (p<0.01) (Nam, Gae-Won, et al. "Changes in skin moisturization and skin surface roughness according to the concentration of polyol and oil among cosmetic raw materials." Journal of the Korean Cosmetic Society 31.4 (2005): 337-342.).

In addition, the use of polyol in the skin care emulsified formulation can reduce the preservative content and thus improve the usability and stability of the manufactured cosmetic. More specifically, by using the antibacterial and antiseptic power of polyol, the antiseptic power can be increased up to 40% or more by adjusting the polyol compounding amount in emulsified products. (Shin Gye-ho, et al. "Study on Antibacterial and Preservative Effects of Polyols for Reduction of Chemical Preservatives." Journal of the Korean Cosmetic Society 33.2 (2007): 111-115.)

On the other hand, when preparing a cosmetic in a stick formulation, when additionally adding wax to secure sufficient hardness, the viscosity of the cosmetic content increases, making it more difficult to fill the product. When product filling is difficult due to increased wax content, and high temperatures are treated as a detour, moisture evaporates when manufacturing cosmetics, especially stick cosmetics of O / W formulation with water in the external surface. is difficult Therefore, while seeking various ways to facilitate the production of solid or semi-solid cosmetics of O / W formulation, polyol can control the hardness and specifically increase the hardness in solid or semi-solid cosmetics of O / W formulation confirmed and completed the present invention.

In order to achieve the above object, in one aspect, the present invention provides a composition for increasing the hardness of O / W cosmetics containing a polyol as an active ingredient.

In addition, in one aspect, the present invention provides a solid or semi-solid cosmetic composition of O / W formulation, including the composition for increasing the hardness.

In addition, in one aspect, the present invention provides a method for increasing the hardness of O / W cosmetics, including the step of adding a polyol to the water phase part of O / W cosmetics.

In one aspect, the polyol of the present invention can increase the hardness of cosmetics in an O / W formulation, so that the hardness of the cosmetic can be easily adjusted. In particular, when manufacturing O/W cosmetics in solid or semi-solid form, simply increasing the content of wax instead of increasing the content of polyol inevitably increases the filling temperature of the product. It causes acceleration of evaporation and denaturation of contents. Therefore, when the polyol of the present invention is used in the manufacture of stick cosmetics of O/W formulation, it is possible to manufacture cosmetics that exhibit a more moist feeling of use without denaturation of the contents in the cosmetics.

Moreover, in another aspect, when color cosmetics such as lipsticks are prepared by adding water-soluble pigments to the aqueous phase of O/W formulation cosmetics whose hardness is adjusted using polyol, the durability of the color tone is remarkably increased, while maintaining moisture At the same time, it can be achieved by maximizing the original purpose of cosmetics that pursues aesthetic beauty.

It will be described in detail below.

In one aspect, the present invention provides a composition for increasing the hardness of O / W cosmetics, including a polyol as an active ingredient.

In one example, the polyol is butylenes glycol, glycerine, propanediol, pentylene glycol, 1,2-hexanediol, and ethyl At least one selected from the group consisting of hexanediol (Ethyl Hexanediol), preferably butylene glycol or propanediol, but is not limited thereto.

As an example, the polyol may be added in an amount of 3 to 20% by weight based on the total weight of the O / W cosmetics, specifically 3 or more, 4 or more, 5 or more, 6 or more, 7 or more, 8 or more, 9 or more, 10 or more, 11 or less, 12 or less, 13 or less, 14 or less, 15 or less, 16 or less, 17 or less, 19 or less, or 20 or less, but is not limited thereto.

In one embodiment, the 'O/W cosmetics' is also referred to as 'oil-in-water cosmetics', and refers to cosmetics in the form of emulsions in which fat and oil become small particles and are dispersed.

For example, the O/W cosmetic may have various forms, but the form affected by the hardness by the addition of polyol may be a solid or semi-solid form, and more preferably may be a solid form, but is not limited thereto. In this case, the 'solid' refers to a regular shape in which particles are regularly present and the quality of the object is hard and hard. The 'semi-solid' is not a solid form, but has a non-flowing form, and is also referred to as a non-flowing liquid form. It is a form in which internal particles do not regularly exist.

The O/W cosmetics include an aqueous phase and an oil phase, and for example, the oil phase may be included in 50 to 80% by weight with respect to the total cosmetics. Specifically, the oil phase is 50 or more, 51 or more, 52 or more, 53 or more, 54 or more, 55 or more, 56 or more, 57 or more, 58 or more, 59 or more, 60 or more, 61 or more, 62 or more, 63 64 or more, 65 or more, 66 or more, 67 or more, 68 or more, 69 or more, 70 or more, 71 or more, 72 or more, 73 or more, 74 or more, 75 or more, 76 or less, 77 or less, 78 or less, 79 or less, Or it may be 80 or less, and more preferably may be included in 70 to 80% by weight, but is not limited thereto. In one embodiment, when 70 to 80% by weight of the oil phase is included for O / W cosmetics, the flowability of the formulation is reduced due to the increase in the internal phase (oil phase part) in O / W formulation cosmetics, so that the solid or semi-solid form of cosmetics is optimized this can be manufactured. In addition, for example, the polyol is preferably included in an aqueous phase rather than an oil phase, but is not limited thereto.

For example, the O/W cosmetic may be filled at 80° C. or lower, and is preferably filled at 75° C. or lower. Preferably, when the O/W cosmetic is a product that is filled at a low temperature, hardness control using polyol is useful, and specifically, filling at 80 ° C or less, 79 ° C or less, 78 ° C or less, 77 ° C or less, 76 ° C or less It can be, preferably 75 ℃ or less, 74 ℃ or less, 73 ℃ or less, 72 ℃ or less, 71 ℃ or less, 70 ℃ or less, 69 ℃ or less, 68 ℃ or less, 67 ℃ or less, 66 ℃ or less, 65 ℃ or less , 64 ℃ or less, 63 ℃ or less, 62 ℃ or less, 61 ℃ or less, may be 60 ℃ or less, but is not limited thereto.

For example, the O/W cosmetics may be color cosmetics or basic cosmetics.

Ingredients included in the present composition include materials other than polyol as an active ingredient, particularly ingredients commonly used in cosmetic compositions, such as antioxidants, stabilizers, solubilizers, vitamins, pigments, and conventional adjuvants such as perfumes, and carriers. may further include.

The color cosmetics may include without limitation any stick-type cosmetics in an O/W formulation, and may be, for example, a stick foundation, lipstick, lip gloss, tint, or cream foundation, but are not limited thereto. At this time, when color cosmetics such as lipstick are manufactured by adding water-soluble pigments to the water phase of O/W cosmetics, the durability of the color tone is significantly increased, maximizing the original purpose of cosmetics that pursues aesthetic beauty while maintaining moisture. can be achieved by

The basic cosmetics may include both stick-type skin care and balm-type skin care products, and may be, for example, cream, eye cream, or lip balm, but is not limited thereto.

In one embodiment, the 'hardness' refers to the magnitude of resistance to deformation of the object when the object is pressed by another object. In this regard, as an example, the hardness of the O/W cosmetics may be 40 g or more in average hardness measured by a piano string based on a cylinder having a diameter of 10.7 to 11.1 mm. Specifically, the hardness of the O / W cosmetic has an average hardness of 40 g or more, 41 g or more, 42 g or more, 43 g or more, 44 g or more, 45 g or more, 46 g or more when measured under the conditions of Table 3 below. , 47 g or more, 48 g or more, 49 g or more, 50 g or more, 51 g or more, 52 g or more, 53 g or more, 54 g or more, 55 g or more, 56 g or more, 57 g or more, 58 g or more, 59 g or more, may be 60 g or more, but is not limited thereto.

Hereinafter, examples and experimental examples will be described in detail to aid understanding of the present invention. However, the following Examples and Experimental Examples are merely illustrative of the contents of the present invention, but the scope of the present invention is not limited to the following Examples and Experimental Examples. Examples and experimental examples of the present invention are provided to more completely explain the present invention to those skilled in the art.

Example 1. Confirmation of hardness increase of solid cosmetics according to addition of polyol-1

Samples #11 and #12 were prepared with the composition and contents shown in Table 1 below. At this time, sample #11 was used as a control for #12.

Specifically, the materials of the oil phase part in Table 1 below were weighed in the amounts described and added to the beaker. Separately, the materials of the water phase part in Table 1 below are weighed in the indicated amounts and added to the beaker. Thereafter, the material in the beaker to which the water phase part was added was heated to 70 to 80 ° C, and the material in the beaker to which the oil phase part was added was heated to 85 to 95 ° C to sufficiently melt the wax, and then cooled to 80 to 85 ° C. Then, the material of the oil phase part is slowly added to the beaker into which the material of the water phase part has been added. After this, it was stirred at 5000 rpm. When emulsification proceeds to a certain extent, a thickener is added to finish the manufacturing process, and then the contents are degassed and cooled to be discharged. The discharged contents are put into a heated tank and melted by stirring with a pedal. After that, the cosmetic case was filled, and the temperature at this time was 75 ° C. Samples #11 and #12 prepared according to the above method have a stick shape with a cylindrical column having a diameter of 10.7 to 11.1 mm.

After that, in order to measure the hardness of the cosmetics of #11 and #12 under the conditions described in Table 2, the hardness of the piano wire was measured for the thickest part at 30 ° C using a RHEO METER (Model: CR-300). did The results are shown in Table 1.

Raw material #11 #12 paid part Wax 1 (melting point 80-90); Polyethylene 6.00 6.00 Wax 2 (melting point 65-75); CANDELILLA WAX 6.00 6.00 Wax 3 (melting point 55-65); Paraffin 6.00 6.00 ester oil 10.00 10.00 hydro carbon oil 24.00 24.00 Emulsifier (High HLB) 9.70 9.70 Emulsifier (Low HLB) 4.80 4.80 preservative raw materials; Dehydroacetic acid 0.05 0.05 pigment 11.40 11.40 award part water; Water 20.00 15.00 chelating agents; DISODIUM EDTA 0.05 0.05 water soluble pigment 2.10 2.10 polyols; Butylene glycol (BG) - 5.00 water soluble thickeners; Water*Polyacrylate-13*Polyisobutene*Polysorbate 20*Sorbitan Isostarate 0.25 0.25 Average hardness (measured by piano strings) 73 133

As can be seen in Table 1, sample #12 to which butylene glycol (BG), which is a polyol, was additionally added exhibits hardness about twice as high as that of sample #11, which is a control group. This indicates that the polyol can be used as a material for increasing the hardness of o/w formulation cosmetics.

Example 2. Confirmation of hardness increase of solid cosmetics according to addition of polyol-2

In order to reconfirm whether the hardness increase effect of o/w formulation cosmetics is due to polyol, the sample composition of Example 1 is changed to new samples (sample #16-1, #16-2, #16-3, # 16-4, #16-5, and #16-6) were prepared and the effect was confirmed. Modification of the sample composition focused on controlling factors that could affect hardness, that is, 'adjustment of wax content and composition ratio', 'removal of ester oil', and 'removal of thickener'.

Specifically, the materials of the oil phase part in Table 3 below were weighed in the amounts described and added to the beaker. Separately, the materials of the aqueous phase part in Table 3 below are weighed in the indicated amounts and added to the beaker. Thereafter, the material in the beaker to which the water phase part was added was heated to 70 to 80 ° C, and the material in the beaker to which the oil phase part was added was heated to 85 to 95 ° C to sufficiently melt the wax, and then cooled to 80 to 85 ° C. Then, the material of the oil phase part is slowly added to the beaker into which the material of the water phase part has been added. After this, it was stirred at 5000 rpm. When emulsification proceeds to a certain extent, the contents are degassed and cooled to be discharged. The discharged contents are put into a heated tank and melted by stirring with a pedal. After that, the cosmetic case was filled, and the temperature at this time was 75 ° C. Samples #16-1, #16-2, #16-3, #16-4, #16-5, and #16-6 prepared according to the above method are in the form of sticks having cylindrical pillars with a diameter of 10.7 to 11.1 mm. have

Then, in order to measure the hardness of the cosmetics of the samples #16-1, #16-2, #16-3, #16-4, #16-5, and #16-6 under the conditions described in Table 3 Piano string hardness was measured for the thickest part at 30 ° C using a RHEO METER (Model: CR-300). The results are shown in Table 3.

Raw material #16-3 #16-1 #16-2 #16-5 #16-4 #16-6 paid part Wax 1 (melting point 80-90); Polyethylene 7.00 7.00 7.00 7.00 7.00 7.00 Wax 2 (melting point 65-75); CANDELILLA WAX - - - - - - Wax 3 (melting point 55-65); Paraffin 6.00 6.00 6.00 6.00 6.00 6.00 ester oil - - - - - - hydro carbon oil 35.00 35.00 35.00 35.00 35.00 35.00 Emulsifier (High HLB) 9.70 9.70 9.70 9.70 9.70 9.70 Emulsifier (Low HLB) 4.85 4.85 4.85 4.85 4.85 4.85 preservative raw materials; Dehydroacetic acid 0.05 0.05 0.05 0.05 0.05 0.05 pigment 11.40 11.40 11.40 11.40 11.40 11.40 award part water; Water 20.00 15.00 10.00 15.00 10.00 10.00 chelating agents; DISODIUM EDTA 0.05 0.05 0.05 0.05 0.05 0.05 water soluble pigment 1.00 1.00 1.00 1.00 1.00 1.00 polyol Butyleneglycol (BG) - 5.00 10.00 - - - Glycerine - - - 5.00 10.00 - Propanediol - - - - - 10.00 Average hardness (measurement of piano string hardness) X 65 75 47 96 77 Mp(melting point) 55.5 68.8 69.5 65.6 67.2 67.90

As can be seen in Table 3, in the case of sample # 16-3 to which polyol was not added, the hardness could not be measured because a solid was not formed, but when polyol was added, it was found to have a certain level of hardness. In addition, it can be confirmed that the hardness increases as the amount of polyol added increases. At this time, when butylene glycol is added, the hardness can be greatly increased with a small amount. When glycerin is added, a cosmetic product having a high hardness increase rate compared to the same content and the greatest hardness compared to a low melting point can be manufactured.

Example 3. Confirmation of hardness enhancement of semi-solid (liquid form that does not flow) cosmetics by adding polyol

Compared to the samples of Examples 1 and 2, the content of wax was significantly lowered to confirm the change in hardness by polyol in the non-flowing semi-solid cosmetic, rather than a solid stick. Samples #16-8, #16-9, #16-10 and #16-11 were prepared with the composition and contents shown in Table 4 below.

Specifically, the materials of the oil phase part in Table 4 below were weighed in the amounts described and added to a beaker. Separately, the materials of the aqueous phase part in Table 4 below are weighed in the indicated amounts and added to the beaker. Thereafter, the material in the beaker to which the water phase part was added was heated to 70 to 80 ° C, and the material in the beaker to which the oil phase part was added was heated to 85 to 95 ° C to sufficiently melt the wax, and then cooled to 80 to 85 ° C. Then, the material of the oil phase part is slowly added to the beaker into which the material of the water phase part has been added. After this, it was stirred at 5000 rpm. When emulsification proceeds to a certain extent, the contents are degassed and cooled to be discharged. The discharged contents are put into a heated tank and melted by stirring with a pedal. Samples #16-8, #16-9, #16-10 and #16-11 prepared according to the above method were placed in 100 ml cream jars under pressure. At this time, the temperature was 75°C.

After that, RHEO METER (Model: CR-300) was used to measure the hardness of the cosmetics of the samples #16-8, #16-9, #16-10 and #16-11 under the conditions described in Table 5. (The method of measuring hardness is different from Examples 1 and 2 because the formulation is different). The results are shown in Table 4.

As can be seen in Table 4, the cosmetic prepared by adding polyol exhibited an increase in hardness about twice as compared to the cosmetic prepared without adding polyol. In the case of a large difference, a hardness increase of up to about 3.5 times was shown. Among the polyols, the cosmetic prepared by adding propanediol showed the greatest increase in hardness.
