Definitions
- the present invention relates to a particle having an anionic surfactant and a polymeric polycarboxylate.
- cleaning compositions such as granular detergent compositions
- Such detergent compositions offer greater convenience to the consumer and at the same time, reduce the amount of packaging materials which will ultimately be disposed of.
- cleaning compositions tend to encounter problems of poor dissolution.
- builder, filler and/or surfactant which have good water- solubility have been used in such high bulk density detergent.
- Anionic surfactants, especially high level anionic surfactants are a major facilitator of such caking. This caking is very undesirable for consumers. Consequently, there is a need for high active materials used in cleaning compositions to have better physical properties, such as good dissolution, as well as low moisture absorption to minimize caking.
- the present invention relates to an interspersion particle comprising, by weight of the interspersion particle, from about 20% to about 50% anionic surfactant, and from about 15% to about 30% polymeric polycarboxylate, wherein the anionic surfactant and the polymeric polycarboxylate are interspersed within each individual particle, and wherein the weight ratio of the anionic surfactant to the polymeric polycarboxylate is from about 10:4 to about 10:9.
- the invention also relates to compositions comprising one or more interspersion particles.
- the invention also relates to a process for making the interspersion particle and/or compositions comprising one or more interspersion particles.
- the interspersion particle of the present invention answers the need for high active materials for use in a cleaning composition, having better physical properties, such as good dissolution, as well as low moisture absorption to minimize caking. Without being bound by theory, it is believed potential caking of particles containing certain high active materials can be reduced or eliminated by interspersing polymeric polycarboxylate within individual particles containing the high active material. Such interspersion improves the overall physical property, such as anti-caking property, of such interspersion particles and compositions comprising the interspersion particles, including cleaning compositions as a whole which contain the interspersion particles. While the specification concludes with claims particularly pointing out and distinctly claiming the invention, it is believed that the present invention will be better understood from the following description.
