摘要： Solid core particles encapsulated in a single coat of paraffin wax, the wax having a melting point of about 40.degree. to about 50.degree. C. and a solids content of from 100 to about 35% at 40.degree. C. and from 0 to about 15% at 50.degree. C. The paraffin coat may comprise 20 to 90% by weight of the particle and may be from 100 to 1,500 microns thick. The coat prolongs the time in which particles encapsulated therewith may remain active in aqueous environments.The encapsulated particle is made by spraying molten wax onto the particles in a fluidized bed. Liquid or powder cleaning compositions, particularly automatic dishwashing liquid detergents, may incorporate 0.01 to 20% by weight of the composition of the coated wax-encapsulated particles.
摘要翻译： 包封在单一石蜡层中的固体核心颗粒，该蜡具有约40℃至约50℃的熔点，在40℃和0至约15℃的固体含量为100至约35％ ％。石蜡涂层可以包含20-90重量％的颗粒，并且可以是100-1,500微米厚。 涂层延长了包封在其中的颗粒在水性环境中保持活性的时间。 包封的颗粒通过在流化床中将熔融蜡喷射到颗粒上而制成。 液体或粉末清洁组合物，特别是自动餐具洗涤液体洗涤剂，可以包含涂料蜡包封颗粒组合物的重量的0.01％至20％。
