  • Publication number: 20250222631
    Abstract: A continuous process for preparing a sheet article includes preparing a wet pre-mixture comprising a water-soluble polymer and a surfactant and having a viscosity of from 1,000 cps to 25,000 cps measured at 40° C. and 1 s?1; aerating said wet pre-mixture to form an aerated wet pre-mixture having a density of from 0.05 to 0.5 g/ml; forming said aerated wet pre-mixture into a sheet having a top side and a bottom side; and drying said formed sheet of aerated wet pre-mixture on a conveying belt with the bottom side of said formed sheet contacting said conveying belt.

  • Patent number: 9828569
    Abstract: This relates to granular laundry detergent products characterized by efficient mass and volume compaction, fast dissolution or dispersion and enhanced suds profile, which are particularly useful for hand-washing fabric under suboptimal washing conditions.

  • Publication number: 20170321169
    Abstract: A cleaning composition, preferably a granular laundry detergent composition, contains 1.5 wt % to 10 wt % of soap particles characterized by a particle size distribution with from 35 wt % to 100 wt % of soap particles having particle sizes ranging from about 125 microns to about 355 microns. Soap particles with such a particle size distribution are surprisingly more effective in boosting suds volume of the cleaning composition during a fabric washing cycle.

  • Publication number: 20160272926
    Abstract: This relates to structured detergent particles with high-level surfactant activity, which contains about 50-90 wt % of a C10-C20 linear alkyl benzene sulphonate, about 10-50 wt % of a hydrophilic silica, and about 0-35 wt % of a water-soluble salt of an alkaline metal. Such structured detergent particles demonstrate better flowability and less moisture uptake, and are therefore particularly useful for forming free-flowing finished detergent products that are less vulnerable to caking over time.

  • Publication number: 20160083677
    Abstract: This relates to structured detergent particles with mid-level surfactant activity, which contain 35-50 wt % of a C10-C20 linear alkyl benzene sulphonate, 0.5-8 wt % of a hydrophilic silica, 35-70 wt % of a water-soluble alkaline metal carbonate, 0-5 wt % of a phosphate builder, and 0-5 wt % of a zeolite builder. Such structured detergent particles are free flowing with little or no moisture content (i.e., 0-3 wt % water), and are formed by a dry neutralization process without any subsequent drying.

  • Publication number: 20140317858
    Abstract: The present invention relates to a detergent granule comprising a water-swellable component (e.g., CMC), neutralizing agent (e.g., Na2CO3) and anionic surfactant, as well as a process for making same. Granular detergent compositions comprising the detergent granules and methods of using thereof are also encompassed.
