  • Fabric conditioning compositions and process for making them
    Patent number: 5411671
    Abstract: An aqueous fabric conditioning composition comprising a homogeneous dispersion of fabric conditioning active particles having a size distribution such that the particles have a mean size of about 0.7 to 10 microns as measured by Malvern Particle Size Analyzer and preferably have 10% of the distribution with a particle size of at least 23% of the mean particle size. The composition is obtained by a continuous process for making the aqueous fabric conditioning composition.
    Type: Grant
    Filed: January 5, 1994
    Date of Patent: May 2, 1995
    Assignee: Lever Brothers Company, Division of Conopco, Inc.

  • Cleaning compositions with skin protection agents
    Patent number: 4695395
    Abstract: Isethionate salts have been discovered to provide protection for the skin against damage from contact with soap or other surfactants. A mild to the skin cleaning composition is provided comprising fatty acid soap in amounts greater than 25% and an isethionate salt such as sodium isethionate, the ratio of soap to isethionate ranging from 1:2 to abut 200:1. Sodium C.sub.8 -C.sub.18 acyl isethionate may be incorporated as a further component into the cleaning composition, although in an amount not to exceed that of the soap.
    Type: Grant

  • Process for preparing soap-acyl isethionate toilet bars
    Patent number: 4663070
    Abstract: A process is disclosed for preparing a toilet bar composition whose components comprise a fatty acid soap and a C.sub.10 -C.sub.16 acyl isethionate salt in the ratio of about 20:1 to 1:0.98, respectively. The blend is charged with an initial amount of water from 12 to 30% by weight of the composition. Heating and mixing are terminated after the blend has passed a second peak in viscosity, termination occurring between about 500 and 6,000 centipoise at 35 sec.sup.-1 shear rate at 210.degree.-218.degree. F. The final moisture content of the blend must be between 8.5 to 20% water.
