Description
Technical Field
The invention relates to a water-release sunscreen cosmetic. In the present invention, a composition for a cosmetic material may be described as a cosmetic material.
Background
In the case of sunscreen cosmetics, organic ultraviolet absorbers such as ethylhexyl methoxycinnamate are used in order to impart an ultraviolet protection effect, and since these have poor compatibility with silicone, stabilization of silicone-based cosmetics is difficult. Therefore, if a large amount of the organic ultraviolet absorber is blended, the feeling is also deteriorated, and there is a problem that discoloration, odor, or the like occurs.
In recent years, as a measure against sunburn in daily life, there has been developed an oil-in-water type sunscreen cosmetic composition which is easy to continuously use with a water-wet feeling of use and does not deteriorate the feeling of use of an organic ultraviolet absorber (patent document 1: Japanese patent laid-open No. 2013-91625). However, the following problems are present in the case of oil-in-water type cosmetics: the water resistance is low and the film easily falls off due to exposure to sweat, water, or the like.
On the other hand, in order to obtain a water-in-oil type cosmetic material having a moist feel, it is known that a cosmetic material having a moist feel in use can be obtained by preparing an emulsion having a high water content and a large particle size using a partially crosslinked polyether-modified silicone (patent document 2: Japanese patent laid-open No. 2001-2521). It is also known that by designing the emulsion particle size of such a large particle size, a water-releasing type cosmetic can be prepared.
Furthermore, a technique is known in which a water-moist sunscreen cosmetic is obtained by using an ultraviolet scattering agent and an absorbent together in a water-in-oil type cosmetic having a high internal water phase (patent document 3: Japanese patent laid-open No. 2009-242294). However, since the active agent is excessively blended with the ultraviolet scattering agent, the feeling of water release is not felt, and no study has been made on the relationship between the ratio of the active agent and the feeling of water. In addition, a technique for obtaining a water-in-oil type water-release cosmetic containing an ultraviolet absorber is also known (patent document 4: Japanese patent laid-open publication No. 2011-219448). However, studies on the inclusion of an ultraviolet scattering agent have not been conducted.
From the above, it has been desired to develop a water-releasing sunscreen cosmetic composition which contains an ultraviolet scattering agent, has a good feel and high water resistance, and can provide a moist feel in use.

(a) The amount of the component (B) is 0.1 to 4% by mass, preferably 0.2 to 2% by mass of the total cosmetic. If the amount is less than 0.1% by mass, the emulsion stability of the cosmetic is lowered, and if the amount is more than 4% by mass, the water-moist feeling is lost, and the feeling in use during application may be impaired.
(a) The component (b) can be used alone in 1 kind or in an appropriate combination of 2 or more kinds, and for example, in the case where the relative blending ratio of the partially crosslinked polyether-modified silicone in the combination of the partially crosslinked polyether-modified silicone and the partially crosslinked polyglycerol-modified silicone is high, spreadability of the cosmetic material tends to be improved, and in the case where the relative blending ratio of the partially crosslinked polyglycerol-modified silicone is high, the cosmetic material tends to have a wet soft feeling in use. The blending ratio can be appropriately determined in the control of the feeling of use.
[ (b) component ]
In the water-release sunscreen cosmetic of the present invention, a non-crosslinked silicone active agent is blended, particularly in view of the storage stability of the cosmetic and the adjustment of the feeling of use by the adjustment of the emulsion particle size. The silicone surfactant is not particularly limited as long as it is a non-crosslinking silicone active agent that can be usually blended in a cosmetic, and 1 type can be used alone or 2 or more types can be used in combination as appropriate. Among these surfactants, preferred are linear or branched polyoxyethylene-modified organopolysiloxanes, linear or branched polyoxyethylene polyoxypropylene-modified organopolysiloxanes, linear or branched polyglycerol-modified organopolysiloxanes, linear or branched polyoxyethylene-alkyl co-modified organopolysiloxanes, linear or branched polyoxyethylene polyoxypropylene-alkyl co-modified organopolysiloxanes, acrylic-silicone graft copolymers, and the like. Specific examples thereof include polyether-modified silicones such as KF-6011, 6013, 6043, 6017P, etc., silicone-branched polyether-modified silicones such as KF-6028, 6028P, etc., silicone-branched polyglycerin-modified silicones such as KF-6100, 6104, 6106, etc., acrylic-silicone-based graft copolymers such as KP-578, silicone-alkyl-branched polyether-modified silicones such as KF-6038, alkyl-branched polyether-modified silicones such as KF-6048, silicone-alkyl-branched polyglycerin-modified silicones such as KF-6105, etc. (all manufactured by shin-Etsu chemical Co., Ltd.).
In addition to the above-mentioned purposes, these non-crosslinking silicone active agents are also used for the purpose of dispersing component (d) well. In particular, when a higher dispersing effect of the component (d) is desired, non-crosslinked polyglycerol-modified silicones are preferable, and specific examples thereof include KF-6100, 6104, 6106, KF-6105 and the like, and branched polyglycerol-modified silicones such as KF-6106, KF-6105 and the like are particularly preferable.
(b) The amount of the component (b) is 0.05 to 2% by mass, preferably 0.2 to 1.6% by mass, more preferably 0.5 to 1.6% by mass of the total amount of the cosmetic composition of the present invention. When the amount is 0.05% by mass or more, the emulsion stability of the cosmetic is further improved, and when the amount is 2% by mass or less, a moist feeling and a good feeling in use when applied can be obtained.
[ (c) component ]
The component (c) in the present invention is not particularly limited as long as it is an aqueous component that can be usually blended in a cosmetic. Specifically, water, a moisturizer, a water-soluble polymer compound, a skin-beautifying component, a water-soluble inorganic salt, a pH adjuster, and the like can be mentioned. These can be used alone in 1 kind or more than 2 kinds are appropriately combined.
Examples of the water include purified water, fruit water, and plant water generally used in cosmetics, and include seawater, hot spring water, and peat water defined by the names. When water is added, the amount of water added is preferably 5 to 85% by mass of the component (c). If the amount is less than 5% by mass, the feeling of water release is hard to feel, and if the amount is more than 85% by mass, the stabilization of the cosmetic may be difficult.

Specifically, the metal oxide is 1 or 2 or more kinds selected from titanium oxide, zinc oxide, and cerium oxide. The metal oxide may be a composite powder of 2 or more kinds of titanium oxide, zinc oxide, and cerium oxide, or may be a composite powder with other powders. The average primary particle diameter is 200nm or less, preferably 150nm or less. When the particle diameter is larger than 200nm, the ultraviolet ray protection function is lowered and a white residue remains. The lower limit is not particularly limited, and may be 10 nm. The average primary particle diameter of the powder used as the ultraviolet scattering agent defined in the present invention is an average value of 20 particles obtained by a transmission electron micrograph. When the powder is not spherical, the average primary particle diameter is defined as the average of the major diameters of the particles.
The component (d) of the present invention is a hydrophobized ultraviolet scattering agent. The hydrophobization treatment is not particularly limited as long as it is a known surface treatment generally used in cosmetics. Examples of the inorganic treating agent include a silica coating, an alumina coating, and an aluminum hydroxide coating.
Examples of the organic treating agent include silicone oils such as silanes and silylating agents, e.g., octylsilane (manufactured by shin-Etsu chemical Co., Ltd.: AES-3083), dimethylsilicones (manufactured by shin-Etsu chemical Co., Ltd.: KF-96A series), methylhydrogenpolysiloxanes (manufactured by shin-Etsu chemical Co., Ltd.: KF-99P, KF-9901, etc.), and silicone branched silicone treating agents (manufactured by shin-Etsu chemical Co., Ltd.: KF-9908, KF-9909, etc.); waxes; organic fluorine compounds such as paraffins and perfluoroalkyl phosphates; a surfactant; amino acids such as N-acyl glutamic acid, and metal soaps such as aluminum stearate and magnesium myristate. In particular, KF-9909 (manufactured by shin-Etsu chemical Co., Ltd.) exhibits high dispersibility in oil agents such as silicone oil and ester oil, and is therefore used for sunscreen cream and foundation. These surface treatments may be used in combination of 1 or 2 or more, and all combinations of inorganic and inorganic, organic and organic, inorganic and organic, and the like may be used depending on the purpose.
Commercially available ultraviolet scattering agents having been subjected to such surface treatment can also be used.

(d) The amount of the component (b) is 0.1 to 21% by mass of the total cosmetic composition, and is preferably 1 to 18% by mass, more preferably 3 to 15% by mass, from the viewpoint of usability and masking property. If the amount is less than 0.1% by mass, a sufficient ultraviolet shielding effect cannot be obtained, and if the amount exceeds 21% by mass, ductility during use may deteriorate and a water-releasing feeling may not be obtained.
The mass ratio of the component (b) to the component (d) represented by (b)/(d) is 0.05 to 0.4, preferably 0.07 to 0.35, and more preferably 0.08 to 0.3. If the amount is less than 0.05, the stability and spreadability are poor, and if the amount exceeds 0.4, the feeling of water release is not obtained.

From the results shown in tables 2 and 4, it is clear that the water-releasing sunscreen cosmetic compositions of examples 1 to 6 are excellent in stability (50 ℃.1 month), feeling of water release (the state of water droplets bursting apart), spreadability (spreadability), feeling of use (non-stickiness), and water resistance (resistance to falling off by sweat). From the results in table 4, it is understood that example 5 in which the component (b) as the dispersant was a non-crosslinked polyglycerin-modified silicone further felt a water-releasing feeling.
Comparative example 1, which does not contain the component (a) of the present invention, is inferior in stability because of poor emulsified state. In comparative examples 3 and 4 in which the amount of component (b) was large and comparative example 6 in which the ratio (b)/(d) exceeded 0.4, no water-releasing feeling was felt, and in comparative example 7 in which the ratio (b)/(d) was less than 0.05, the stability and spreadability were poor. Satisfactory characteristics were not obtained in comparative example 5 in which the amount of component (c) was small and comparative example 8 in which an ultraviolet scattering agent that had not been subjected to hydrophobic treatment was used instead of component (d). From the results of comparative example 2, it is clear that a small amount of component (b) contributes to improvement in stability.
