  • Patent number: 10900168
    Abstract: A fabric treatment composition is provided that includes at least one zeta potential modifier, a fluoropolymer and a hydrophobic agent with a melting point or glass transition temperature below 100° C., for imparting fabric protection benefits to a fabric, such as improved stain and soil resistance, oil repellency, water repellency, softness, wrinkle and damage resistance, and better hand feel. Fabric treatment compositions can be used as a pretreatment prior to washing, through soaking, or added to the treatment liquor, that is either the wash or rinse cycle of an automatic washing machine, to first provide and then maintain and refresh the fabric protection benefits imparted to the fabric. Following use of a first treatment composition, protective benefits are maintained and refreshed by means of a second treatment operation employing a second treatment composition.

  • Patent number: 10844445
    Abstract: The invention concerns a process for tanning hide to obtain leather. The general process for obtaining the intermediary wet blue stage comprises the following steps: a) a picking step with acid and salt, followed by b) a tanning step with chromium salt, followed by c) a basification step. The invention is characterized in that between step b) and c), a re-acidification step with organic acids is added. In particular the organic acids are selected from glutaric acid (GA), 2-methyl glutaric acid (MGA), succinic acid, ethyl succinic acid (ESA), adipic acid (AA), maleic anhydride, fumaric anhydride, tricarboxylic acids, hydroxycarboxylic acids, and mixture thereof.

  • Patent number: 10836984
    Abstract: This disclosure provides a method for stabilizing both lipase and protease in liquid enzymatic laundry detergent, comprising steps of: first, self-assembling conjugated linoleic acid with protease and lipase, respectively, to form vesicles encapsulated protease and vesicles encapsulated lipase at a low Ca2+ concentration; then, mixing the solution of vesicles encapsulated protease and the solution of vesicles encapsulated lipase, and then partially cross-linking conjugated linoleic acid molecules on the vesicles' surface. The obtained enzyme vesicles, after being concentrated, can be used directly in liquid laundry detergent. The lipase in the liquid laundry detergent will not be degraded by protease, and the enzymes in vesicles are able to resist against surfactant inhibition. Thus, the enzyme activities can be maintained in the liquid laundry detergent, and the enzymatic vesicles will be broken to release enzymes, when the liquid laundry detergent is used at a higher Ca2+ concentration such as in tap water.

  • Patent number: 10829721
    Abstract: Enzymes tend to be inactivated during wash by a bleach catalyst in combination with a source of organic peroxyacids. The risk of enzyme inactivation by active bleach catalyst is reduced when the release of the enzyme into the wash solution is delayed. The enzyme stability during washing together with a bleach catalyst can be improved by applying a delayed-release coating to cores which comprise the enzyme.

  • Patent number: 10619283
    Abstract: Washed laundry that has been rinsed still contains bound acidic or basic rinsing liquid. In many cases this must be neutralized. This used to be conducted on the basis of values gained from experience, which generally resulted in only partial neutralization. Herein, sample liquid is taken continuously from the neutralization chamber (18) and, after the fine filtration of same, the pH value of the sample liquid is continuously measured by a pH value measurement device (31). In this manner a pH value control system is possible which ensures an automatic and complete neutralization of the rinse liquid still bound in the laundry after rinsing.
