[Solution] This sunscreen cosmetic is characterized by including: (A) a UV ray absorption agent; (B) a chemical agent selected from the group consisting of L-ascorbic acid and derivatives thereof, tranexamic acid and derivatives thereof, alkoxy salicylic acid and derivatives thereof, glycyrrhizic acid and derivatives thereof, and nicotinic acid and derivatives thereof; (C) a water-soluble thickening agent that is not derived from sugar; and (D) water.

Description

Technical Field

[0001] The present invention relates to an oil-in-water type emulsifying sunscreen cosmetic that has high ultraviolet ray protection and can incorporate a drug in the internal phase.

Background Art

[0002] Ultraviolet rays are one of the factors that damage the skin, and it is known that when exposed to strong ultraviolet rays, excessive production of melanin pigment occurs, causing freckles and chloasma. Therefore, protecting the skin from the harm of ultraviolet rays and restoring the skin damaged by ultraviolet rays are one of the important issues in skin care and body care.

[0003] As a cosmetic for protecting the skin from the harm of ultraviolet rays, there is a sunscreen cosmetic that absorbs or scatters UVA and UVB to suppress the amount of ultraviolet rays reaching the skin. In sunscreen cosmetics, in order to obtain high ultraviolet ray protection, an oil-in-water type emulsifying cosmetic is preferred because an ultraviolet absorber or an ultraviolet scattering agent can be stably incorporated and sufficient water resistance can be obtained. However, in an oil-in-water type emulsion, since the outer layer is an oil phase, it is necessary to suppress greasiness and stickiness.

[0004] For example, in Patent Document 1, it is described that in an oil-in-water type emulsifying sunscreen cosmetic, by combining and incorporating silicone skeleton powder, methyl polymethacrylate powder, and hydrophobized plate-like powder, a cosmetic having a high ultraviolet ray protection effect and no greasiness or stickiness was obtained.

[0005] On the other hand, as a cosmetic for restoring the skin from damage by ultraviolet rays, skin care cosmetics containing drugs such as whitening agents and anti-inflammatory agents are preferred. So far, in oil-in-water type emulsifying cosmetics, no consideration has been given to exerting the drug effect and enhancing the ultraviolet ray protection.

[0036] It was also confirmed that when using a non-salt agent, the improvement rate of ultraviolet ray protection ability tends to be even better. Therefore, in the present invention, it is more preferable to use the above-mentioned non-salt agent.

[0037] (B) The blending amount of the agent is 0.05 to 3% by mass, preferably 0.1 to 3% by mass, and more preferably 0.5 to 2% by mass based on the total amount of the sunscreen cosmetic. If the blending amount of (B) the agent is less than 0.05% by mass, it is difficult to obtain sufficient drug efficacy, and if it is blended in excess of 3% by mass, it is not preferable in terms of deterioration of stability and usability.

[0038] <(C) Water-soluble thickener> The (C) water-soluble thickener (hereinafter sometimes simply referred to as the "(C) component") blended in the sunscreen cosmetic of the present invention is a water-soluble thickener usually blended in cosmetics, and is selected from water-soluble thickeners excluding those derived from sugars. Specifically, although not limited, it is preferably selected from vinyl polymers, acrylic polymers, acrylate synthetic polymers, and hydrophobically modified polyether urethanes.

[0039] Examples of vinyl polymers include polyvinyl alcohol, polyvinyl acetate, polyvinyl methyl ether, polyvinyl pyrrolidone, a copolymer of vinyl pyrrolidone and vinyl acetate, carboxyvinyl polymer, etc.

[0040] Examples of acrylic polymers include sodium polyacrylate, polyethyl acrylate, polyacrylic acid alkanolamine, alkyl methacrylate and dimethylaminoethyl methacrylate copolymer, poly-2-acrylamido-2-methylpropanesulfonic acid, polymethacryloyloxytrimethylammonium, (acryloyldimethyltaurine ammonium / VP) copolymer, (dimethylacrylamide / sodium acryloyldimethyltaurate) cross-polymer (「SU-GEL」, Toho Chemical Co., Ltd.), and the like.

[0041] Examples of acrylate synthetic polymers that can be used include (acrylates / stearyl methacrylate-20) copolymer (「Aculyn (registered trademark) 22」, The Dow Chemical Company), (acrylates / C10-30 alkyl acrylate) cross-polymer (「Pemulen (registered trademark) TR-2」, Nikko Chemicals Co., Ltd.), and the like.

[0042] The hydrophobically modified polyether urethane refers to an associative thickener represented by the following general formula (1). R 1 -{(O-R 2 ) k -OCONH-R 3 [-NHCOO-(R 4 -O) n -R 5 h} m Formula (1) [In the formula, R 1 , R 2 and R 4 each represent a hydrocarbon group which may be the same or different from each other, R 3 represents a hydrocarbon group which may have a urethane bond, R 5 represents a linear or branched divalent hydrocarbon group, m is an integer of 2 or more, h is an integer of 1 or more, and k and n are each independently an integer in the range of 0 to 1000]

[0043] ​Specific examples of the hydrophobic modified polyether urethane include polyethylene glycol-decyltetradeceth-hexamethylene diisocyanate copolymers. Particularly preferred examples include (PEG-240 / decyltetradeceth-20 / hexamethyl diisocyanate) copolymer (“Adekanol GT-700”, ADEKA Corporation) and the like.

[0044] The (C) water-soluble thickener used in the present invention may be used alone or in combination of two or more. The blending amount of the (C) water-soluble thickener is 0.01 to 2% by mass, preferably 0.02 to 1% by mass, 0.03 to 1% by mass, 0.05 to 1% by mass, more preferably 0.03 to 0.3% by mass, 0.1 to 0.3% by mass, based on the total amount of the sunscreen cosmetic. If it is less than 0.01% by mass, sufficient thickening will not occur and the stability of the internal phase will deteriorate. On the other hand, if it exceeds 2% by mass, it tends to have a sticky usability.

[0045] <(D) Water> (D) Water incorporated in the sunscreen cosmetic of the present invention (hereinafter sometimes simply referred to as “(D) component”) is not particularly limited, and examples include ion-exchanged water, purified water, and natural water. The blending amount of (D) water is 13 to 80% by mass, preferably 15 to 70% by mass, based on the total amount of the sunscreen cosmetic.

[0046] Conventionally, it has been difficult to incorporate a water-soluble whitening agent into the internal phase (aqueous phase) of an oil-in-water emulsion. In the oil-in-water emulsified cosmetic of the present invention, by thickening the aqueous phase with a specific water-soluble thickener, the aqueous phase and the oil phase can be blended at a ratio of 1:7 to 8:1, and it has become possible to stably incorporate a whitening agent.

[0047] <Optional Blending Components> In addition to the above components (A) to (D), components usually used in cosmetics can be incorporated into the sunscreen cosmetic of the present invention within a range that does not interfere with the effects of the present invention. For example, an oil component, an aqueous component, alcohols, a humectant, a thickener, a surfactant, a film-forming agent, a powder component, an ultraviolet light scattering agent, a stabilizer, a chelating agent, a preservative, a fragrance, etc. may be appropriately blended as necessary.

[0048] In the sunscreen cosmetic of the present invention, in order to improve the feel of use, even without blending a volatile cyclic silicone such as cyclopentasiloxane that is usually blended in an oil-in-water emulsion cosmetic, it is non-greasy, has a good feel of use, and a sunscreen cosmetic with improved ultraviolet resistance can be obtained. Therefore, the cosmetic of the present invention includes an embodiment in which cyclic silicone is not blended.

[0049] The sunscreen cosmetic of the present invention can be prepared into dosage forms such as emulsions, creams, lotions, aerosol agents, etc., and can be manufactured using conventional methods suitable for each dosage form.

Examples

[0050] The present invention will be described in more detail with reference to the following examples, but the present invention is not limited thereto in any way. Unless otherwise specified, the blending amount is shown as mass% with respect to the system in which the component is blended. Before specifically explaining each example, the adopted evaluation method will be described.

[0051] 1. Usability Each sample of the examples and comparative examples was actually used by 10 professional panels, and the usability (non-greasiness, freshness) was evaluated. Each panel was given a five-level sensory evaluation according to the following evaluation point criteria, and the determination was made based on the following evaluation criteria according to the total score. 「Evaluation Point Criteria」 5: Extremely excellent 4: Excellent 3: Ordinary 2: Inferior 1: Extremely inferior 「Evaluation Criteria」 A: Total score is 40 points or more B: Total score is 30 - 39 points C: Total score is 29 points or less

[0052] 2. Measurement of the improvement rate of UV resistance Each example of the cosmetic (sample) was dropped onto a measurement plate (S plate) (a 5×5 cm V-groove PMMA plate, SPFMASTER-PA01) in an amount of 2 mg / cm 2 and applied with a finger for 60 seconds. After drying for 15 minutes, the absorbance of the formed coating film was measured using a U-3500 type self-recording spectrophotometer manufactured by Hitachi, Ltd. The uncoated plate was used as a control, and the absorbance (Abs) was calculated by the following formula, and the measured values at 280 nm to 400 nm were integrated to obtain the integrated absorbance value. Abs=-log(T / To) T: Transmittance of the sample, To: Transmittance of the uncoated sample

[0053] From the integrated absorbance value of the obtained sample, the improvement rate of UV resistance was calculated by the following formula with reference to a sample (reference sample) containing no aqueous thickener and drug. [Improvement rate of UV resistance (%)]=[Integrated absorbance value of the sample] / [Integrated absorbance value of the reference sample]×100

[0054] <Examples 1 to 10, Comparative Examples 1 to 6 and Reference Sample> An oil-in-water type emulsified cosmetic having the composition described in Tables 1 and 2 below was prepared. According to the above evaluation method, the usability and the improvement rate of UV resistance were evaluated.

[0055]

Table 1

[0056] As shown in Table 1, when compared with a reference sample containing neither the thickener nor the drug of the present invention, in the cosmetic of Comparative Example 5 containing only the drug (tranexamic acid) of the present invention, an improvement in UV resistance was confirmed. In the cosmetics of Examples 1 to 6 containing various thickeners of the present invention in addition to the drug of the present invention, the improvement rate of UV resistance was further improved. Regarding the cosmetic of Example 5 containing (dimethylacrylamide / sodium acryloyldimethyltaurine) cross-polymer as a thickener, although the usability was slightly inferior, the cosmetics of Examples 1 to 4 and 6 were excellent in terms of feel in use.

[0057] On the other hand, in the cosmetics of Comparative Examples 1 to 4 containing a water-soluble thickener derived from sugar, not only was no improvement in UV resistance observed, but the feel in use was also inferior.

[0058]

Table 2

[0059] As shown in Table 2, in the cosmetics of Examples 7 to 10 containing a combination of the thickener of the present invention and various drugs, a synergistic improvement in UV resistance was confirmed as compared with a reference sample containing neither the drug nor the thickener of the present invention and the cosmetic of Comparative Example 6 containing only the thickener (sodium polyacrylate) of the present invention. Further, this synergistic improvement effect was particularly remarkable when a drug that is not a salt was blended (Examples 7 and 10). In addition, the cosmetics of Examples 7 to 10 were not sticky and were excellent in terms of feel in use.

[0060] The formulations of the cosmetics of the present invention are exemplified below. It goes without saying that the present invention is not limited by these formulation examples and is defined by the claims.
