摘要： It has been reported that many organic sunscreens lose their efficacy on exposure to UV rays. Further some of the organic sunscreens are known to interact with each other when applied on the skin with or without exposure to UV radiation. Thus such compositions are not stable. They are not very effective in blocking the UV-rays a few minutes or hours after the product has been applied to the skin. Further when such compositions are used and then exposed to sunlight or UV rays, the period over which the skin is actually protected is very short, while the consumer is under the mistaken impression that the composition is protecting his/her skin. This false impression can lead to the consumer exposing himself/herself more to sunlight thereby getting more damage to the skin. A solution to the foregoing problem is provided by a stable sunscreen composition comprising: (a) a complex of a first organic sunscreen with a first paramagnetic metal ion; and (b) a second organic sunscreen.
摘要翻译：据报道，许多有机防晒剂在暴露于紫外线下失去功效。另外一些已知的有机防晒剂在用或不暴露于紫外线辐射下施用于皮肤时彼此相互作用。因此，这样的组合物不稳定。它们在产品施用于皮肤后几分钟或几小时内不会非常有效地阻挡紫外线。此外，当使用这些组合物然后暴露于阳光或紫外线时，实际保护皮肤的时间是非常短的，而消费者的组合物正在保护其皮肤的错误印象。这种错误的印象可能导致消费者将自己更多地暴露在阳光下，从而对皮肤造成更多的伤害。上述问题的解决方案由稳定的防晒组合物提供，包括：（a）第一有机防晒剂与第一顺磁性金属离子的络合物; 和（b）第二有机防晒剂。

摘要： This invention relates to a method and composition for treatment of a substrate. It particularly relates to a method and composition for treatment of a fabric substrate for imparting repellency of aqueous and oily soils. It is an object of the present invention is to provide a method of treating a substrate to render the substrate more hydrophobic and to provide repellence to both oily and aqueous soils and stains. It has been found that hydrophobicity and stain-resistance can be imparted to a substrate by contacting the substrate with soap and a water-soluble compound of trivalent or tetravalent metal in presence of water under specific range of pH, while the further addition of a quaternary silicone oil imparts oily soil repellence.

摘要： The invention relates to a method of treating a fabric. It particularly relates to a method of treating a fabric with a rinse product that reduce soil pickup and further ensures that the fabric is cleaner after the subsequent wash. It is thus, an object of the present invention to provide a method of treating a fabric to render the fabrics relatively more hydrophobic and especially to provide a method of treating a fabric during the rinse stage of the fabric cleaning process that reduces subsequent soiling of the fabric during use by the consumer. It has been found that contacting the fabric with a neutral aqueous solution, comprising a water- soluble zinc compound, a deposition aid selected from the group consisting of an amine compound or an amino acid and a soap before drying said fabric, provides the soil repellence to the fabric.
