Abstract

PROBLEM TO BE SOLVED: To obtain a composite pigment having an excellent discoloration- preventing effect, a high dispersing property, a light weight, a smooth touch and a high UV light-shielding effect by applying a specific amount of silica on the surfaces of titanium dioxide particles. SOLUTION: This composite pigment is obtained by applying 15-50 wt.% of silica on the surfaces of titanium dioxide particles. The titanium dioxide particles constituting the pigment preferably have an average particle diameter of 0.01-0.2 μm. When the amount of the silica applied on the titanium dioxide particles is <15 wt.%, the discoloration-preventing effect of the titanium dioxide is low, and the high dispersing property and the smooth touch are not obtained. When the amount of the silica applied on the titanium dioxide particles is >50 wt.%, the UV light-shielding effect is deteriorated, and the objective effect is not obtained. The composite pigment can by processed in the form of a liquid cosmetic, a cream-like cosmetic, an oily solid cosmetic, a pressed solid-like cosmetic, a powdery cosmetic, etc. Although arbitrarily selected in response to the kind of the cosmetic, the amount of the pigment to be added to the cosmetic is preferably 0.5-95 wt.% based on the cosmetic, more preferably 1-50 wt.%.

変質させてしまうことがあった。The fine particle titanium oxide is excellent in the effect of blocking ultraviolet rays, but the conventional surface treatment coating amount has insufficient discoloration stability, poor dispersibility, and is incorporated in a large amount into cosmetics. In this case, the "expansion" at the time of application was heavy, and the usability was extremely poor. In addition, the catalytic activity of the titanium oxide surface may alter the oil or fragrance in the cosmetic.

高い15〜50重量％にすることで解決した。[Means for Solving the Problems] Accordingly, as a result of researching to develop a fine particle titanium oxide having an excellent discoloration prevention effect, high dispersibility, and a light and smooth feeling of use, the results showed that the silica coverage was reduced. The problem was solved by setting the content to 15 to 50% by weight higher than the conventional 0.1 to 5.0% by weight.

である。[0005] That is, the present invention provides a composite pigment characterized in that 15 to 50% by weight of silica is coated on the surface of fine-particle titanium oxide, and a cosmetic containing the same.

ないからである。The fine particle titanium oxide constituting the pigment of the present invention is not particularly limited, but preferably has an average particle diameter of 0.01 to 0.2 μm. That is, when the average particle size of the fine particle titanium oxide is less than 0.01 μm, the effect of blocking ultraviolet rays is reduced, and the bulk is increased in practical use, so that it cannot be blended in a large amount and is not suitable for practical use. On the other hand, if the thickness is 0.2 μm or more, titanium oxide itself is used as a general white pigment, and the ultraviolet shielding effect cannot be expected as compared with the high hiding power.

効果が得られないからである。Further, with respect to the silica to be coated on the composite pigment, the ratio of the coating material to the total composite pigment is preferably 15 to 50% by weight. When the amount is less than 15% by weight, the discoloration preventing effect of titanium oxide is low, and high dispersibility and smooth feeling in use cannot be obtained. On the other hand, if it exceeds 50% by weight, the ratio of titanium oxide is low, so that the effect of blocking ultraviolet rays is impaired and the desired effect cannot be obtained.
