摘要： The present invention relates to an oral care composition comprising catechins. We have found that the catechins tend to darken the colour of the chalk based toothpaste due to its oxidation which happens at the high pH of the toothpaste. Once the catechins are oxidized and darken the colour of the toothpaste it is no longer available as such for providing anti-inflammatory benefits. It is an object of the invention to provide a chalk based toothpaste formulation which does not turn substantially dark due to ox illation of catechins. The present inventors while working with oral care compositions comprising catechins preferably green tea catechins for providing anti-inflammatory benefits, surprisingly found that some selected zinc salts when added in particular quantities do not result in darkening the colour of the toothpaste, and also, when stored, are able to deliver green tea catechins.

摘要： Photostable cosmetic compositions comprising sunscreens, more particularly to cosmetic compositions comprising dibenzoylmethane sunscreens are provided. It is known that dibenzoylmethane and its derivatives are relatively sensitive to ultraviolet radiation and they decompose rapidly under the effect of sunlight. This decomposition is accelerated in the presence of UV-B sunscreens, especially p-methoxycinnamic acid and its derivatives. The present inventors have surprisingly found that cosmetic compositions comprising dibenzoylmethane or its derivative and p-methoxycinnamic acid or its derivative, can be stabilized by incorporating a combination of fatty alcohol ethoxylates and polyalkyleneglycol.
摘要翻译： 提供了包含防晒剂的光稳定化妆品组合物，更具体地涉及包含二苯甲酰甲烷防晒剂的化妆品组合物。 已知二苯甲酰甲烷及其衍生物对紫外线辐射相对敏感，并且它们在阳光的作用下快速分解。 在UV-B防晒剂，特别是对甲氧基肉桂酸及其衍生物的存在下，这种分解被加速。 本发明人惊奇地发现，通过掺入脂肪醇乙氧基化物和聚亚烷基二醇的组合，可以使包含二苯甲酰甲烷或其衍生物和对甲氧基肉桂酸或其衍生物的化妆品组合物稳定。
