Provided is an emulsion cosmetic having the innovative, unprecedented property in which the ultraviolet protection effects do not decrease, and conversely increase, due to heat applied in a usage environment. The present invention pertains to an emulsion cosmetic comprising (A) an ultraviolet protectant, (B) a polyhydric alcohol having an IOB value of 5.0 or lower, and (C) an ester oil having an IOB value of 0.3 or higher.

Emulsion cosmetic

The present invention relates to a cosmetic in which the ultraviolet protection effects are increased by heat, and a method for manufacture thereof. The manufacturing method of the present invention includes

Cosmetic product

A water-in-oil type emulsified cosmetic has an unprecedented property wherein, by coming into contact with perspiration or water, the color development and the color uniformity are improved over the conditions immediately after application. The water-in-oil type emulsified cosmetic includes: (A) an organically modified clay mineral; (B) an oil phase thickener other than the (A) organically modified clay mineral; (C) a non-volatile liquid oil other than a silicone oil; (D) a silicone-based surfactant having an HLB of less than 8; and (E) a colorant; wherein a weight ratio defined by [(A)+(B)]/(C) is at least 0.04 and less than 0.68.

Water-in-oil type emulsified cosmetic

An oil-in-water emulsified sunblock cosmetic has excellent feeling when used and maintains a high ultraviolet-ray protective effect even upon contact with water or sweat. The oil-in-water emulsified sunblock cosmetic contains an (A) ultraviolet-ray protective agent and a (B) fatty acid forming a solid at room temperature, the cosmetic is characterized in that 51% or less of the fatty acid is neutralized, and the formulation ratio ((A)/(B) of the (A) ultraviolet-ray protective agent to the (B) fatty acid is in the range of at least 0.1 and less than 10.0. The cosmetic exhibits the unprecedented and surprising property of contact with water causing an improvement to the ultraviolet-ray protective ability. It is preferable for the cosmetic to contain an (C) oily component having IOB of 0.5 or higher.

Oil-in-water emulsion sunscreen cosmetic

The object is providing a water-in-oil emulsion sunscreen cosmetic having a property not present in the prior art, in which UV protection ability improve upon contact with water, sweat and the like in comparison with that directly after application, and also having pleasant texture and easy to wash off. The present invention provides a water-in-oil emulsion sunscreen cosmetic comprising (A) 6 to 40 mass % of a UV protective agent; (B) an organic-modified clay mineral; (C) an oil-phase-thickening agent, other than (B) and (D) a silicone-based surfactant having an HLB of less than 8, wherein the ratio, [total quantity of component (B) and component (C)]/[total quantity of (E) non-volatile liquid oils except silicone oils], is 0.04 or more and less than 0.68.

The present invention relates to an oil-based cosmetic having the innovative, unprecedented property in which the ultraviolet protection effects increase due to heat. The oil-based cosmetic of the present invention contains

Oil-based cosmetic

The purpose of the present invention is to newly provide a method with which it is possible to appropriately evaluate the protective effect of an external preparation for skin such as a sunscreen cosmetic, particularly to evaluate how a UV-ray protective effect is affected by heat. This evaluation method is characterized by including (1) a step for forming a coating film of an external preparation for skin on a substrate, (2) a step for heat-treating the coating film of the external preparation for skin, and (3) a step for measuring the UV-ray protective effect of the heat-treated coating film of the external preparation for skin. The heat treatment is preferably carried out for at least one minute at a temperature of 30-70&#xb0; C. The step for measuring the UV-ray protective effect preferably includes at least one selected from testing methods that involve comparing some kind of UV-ray protective effect with SPF measurement, UVAPF or PFA measurement, critical wavelength measurement, absorbance measurement, and transmittance measurement. This evaluation method can also be performed in vivo or in vitro.

Method for evaluating protective effect against external damage to skin

The invention provides a cosmetic having strong resistance to contact with water, clothing, fingers, and abrasion with little decline (post-contact) in the cosmetic effects such as UV blocking protection as well as excellent feel on use. The cosmetic contains: (A) plate-shaped powder, (B) 6-40% by mass UV absorber, and (C) cationic surfactant.

Durable sunscreen cosmetic

A water-in-oil emulsified cosmetic preparation that, even without substantially comprising a UV scattering agent: exhibits a higher UV protection effect than immediately after application, as a result of coming in contact with moisture, has excellent appearance, usability, and washability. The water-in-oil emulsified cosmetic preparation includes 6%-40% by mass of a UV absorber (A), an oil phase thickener (B), and at least one hydrophobic powder (C) selected from (i)-(iii), namely (i) hydrophobized talc, (ii) silicone powder having an average particle diameter of at least 30 &#x3bc;m, and (iii) crosslinked polymethyl methacrylate powder having a crosslinking density of at least 40%; and not including a UV scattering agent or containing no more than 6% by mass of same.

Water-in-oil emulsion cosmetic

The present invention provides a water-in-oil type emulsion cosmetic composition with low viscosity while having excellent stability sufficient to withstand the inclusion of a polar oil. A water-in-oil type emulsion cosmetic composition of the present invention is characterized by comprising: (A) 0.1 to 2 mass % of an organically modified clay mineral; (B) 0.1 to 2 mass % of a hydrophobic silica; (C) 2 to 5 mass % of a silicone-type surfactant; (D) an oil component of which 10 to 50 mass % of the total oil component is a non-polar hydrocarbon oil; and (E) 20 to 60 mass % of a water phase component; wherein the (A) organically modified clay mineral and (B) hydrophobic silica total to 0.2 to 2 mass %; and a viscosity of the cosmetic composition as a whole is 1000 to 10000 mPa&#xb7;s (30&#xb0; C.; B type viscometer).

Water-in-oil emulsion cosmetic composition

A sprayable sunscreen cosmetic contains substantially no ultraviolet ray scattering agents which cause whiteness, and which is transparent immediately after being applied/sprayed, and that has excellent ultraviolet ray protection effect and a good sensation in use. The ultraviolet ray protection effect is not reduced, and the effects improve when in contact with water. A water-in-oil emulsified sunscreen cosmetic comprises: (A) 6 to 40 mass % of an ultraviolet ray absorbing agent; (B) an organically modified clay mineral; (C) an oil phase thickener other than the aforementioned (B); (D) a silicone-based surfactant having an HLB of less than 8; (E) a spherical resin powder; and (F) a volatile silicone oil; wherein a ratio defined as [total amount of ingredient (B) and ingredient (C)]/[total amount of (G) non-volatile liquid oils other than silicone oils] is at least 0.04 and less than 0.68.
