    • Aminoplast microcapsules comprising a core of fragrance and a shell of aminoplast polymer, the composition of the shell being from 75-100% of a thermoset resin comprising 50-90% of a terpolymer and from 10-50% of a polymeric stabilizer; the terpolymer comprising: (a) from 20-60% of moieties derived from at least one polyamine; (b) from 3-50% of moieties derived from at least one polyol; and (c) from 20-70% of substituted methylene moieties, the microcapsules additionally optionally comprising up to 25% of a cationic polymer. The capsules are competitive with known aminoplast capsules and have the major advantage that they are formaldehyde-free.
    • 包含芳香核心和氨基塑料聚合物壳的氨基塑料微胶囊,壳的组成为75-100%的包含50-90%的三元共聚物和10-50%的聚合物稳定剂的热固性树脂; 所述三元共聚物包含:(a)20-60%的衍生自至少一种多胺的部分; (b)3-50%衍生自至少一种多元醇的部分; 和(c)20-70%的取代的亚甲基部分,微胶囊另外任选地包含至多25%的阳离子聚合物。 胶囊与已知的氨基塑料胶囊具有竞争力,具有无甲醛的主要优点。

    • A method of making a granulated composition that comprises frangible microcapsules containing at least one active ingredient, such as a fragrance, comprising the application of discrete droplets of an aqueous slurry of the microcapsules on to a non-fluidised bed of powdered material, and then drying, the powdered material having a surface tension as defined by an initial contact angle of slurry with powder of at least 40°, which contact angle does not change by more than 10% within the first 3 seconds of application of slurry to powder material. The granulates made by this method are unusually resilient and can withstand rough treatment (for example, during manufacture of products in which they are incorporated), yet can readily release their contents when required. They are also able to be electrically charged.
    • 制备造粒组合物的方法,其包含含有至少一种活性成分(例如香料)的易碎微胶囊,其包括将微胶囊的水性浆料的离散液滴施加到粉末状材料的非流化床上,然后干燥 粉末材料的表面张力由浆料与粉末的初始接触角定义为至少40°,该接触角在浆料施加到粉末材料的前3秒内不会改变10%以上。 通过该方法制造的颗粒是非常有弹性的并且可以经受粗糙处理(例如,在其被并入其中的产品的制造期间),但是当需要时可容易地释放它们的内容物。 它们也可以带电。
