Problems solved by technology

In addition, this approach requires a deep understanding of the effects of formulation components on phase properties and precise control of the ratios of the various components in the formulation, both of which are difficult to achieve simultaneously, especially on an industrial scale
Furthermore, this approach is inflexible in the formulation range due to the complexity posed by different components and concentrations

Abstract

In a process of making a liquid cleaning composition, adding a gel breaker upstream of an anionic surfactant addition in the recirculatory loop of a recirculatory batch processor mitigates the viscous hexagonal phase whilst providing maximum flexibility in formulating various ingredients in the composition.

Description

technical field [0001] The present invention relates to methods of making liquid cleaning compositions and recirculating batch processors. Background technique [0002] Many common surfactants used in cleaning compositions are difficult to handle in concentrated form. In particular, some anionic surfactants such as alkyl sulfates (AS) and alkyl ethoxy sulfates (AES) are known to exhibit An extremely viscous hexagonal phase, while at slightly higher concentrations a thick but flowable lamellar phase. [0003] To save on shipping and storage costs, it is desirable to handle these anionic surfactants in concentrated form. However, in order to dilute the lamellar phase into the isotropic phase normally present in the final liquid cleansing composition, care must be taken to mitigate the hexagonal phase or at least shorten the time to transition through the hexagonal phase. Otherwise, hours to days may be required to dilute the highly viscous hexagonal phase, and furthermore d...
