  • Patent number: 8349788
    Abstract: This invention discovers that laundry-strength hypochlorite bleach compositions are described by three essential components; hypochlorite, hydroxide, and the concentration ratio (CR), the latter defined as the concentration of hypochlorite over the concentration of hydroxide (also, its reciprocal). The hypochlorite content determines fabric cleaning efficacy, the hydroxide content determines stability, and the CR indicates quality of fabric safety, such quality ranging from damaging to gentle. Therefore, hypochlorite bleach compositions can range from fabric damaging to degrees of fabric protection, depending upon the values of CR. Values of CR (as defined) greater than 30:1 characterize fabric-damaging common regular bleach. By decreasing the ratio value, fabric protection progressively improves to a relatively broad maximum at a ratio value about 2:1.

  • Patent number: 7582595
    Abstract: Methodologies and equipment for preparing a hypochlorite solution bleach consumer product to remove menstrual fluid, underarm perspiration or other hard-to-remove stains from soft fabric articles with reduced damage to the fabric articles when compared with popular chlorine bleaches. The soft fabric articles preferably are in white, although the present invention can also be applied to articles in other colors. In one embodiment, the weight concentration ratio of the alkali metal hydroxide over the hypochlorite salt in the hypochlorite admixture solution is no less than 1:12.5. The hypochlorite admixture solution may contain at least 0.2% by weight of sodium hydroxide and/or have a pH of at least 11.8.

  • Publication number: 20090062172
    Abstract: A cleaning composition that can discharge the color of blood, menstrual fluids, or other organic stains is provided. In particular, the present invention achieves a balance between control of unwanted liquid spreading by lateral wicking on a stained textile fabric to lessen the size of wet spots and maintaining the cleaning efficacy of the composition by means of specific kinds of thickening agents. The composition includes an oxidizing agent such as peroxides, a cell-lysing agent, a chelating agent, an antioxidant, a thickener, and other optional ingredients that are selectively employed to achieve an aqueous based composition that exhibits good shelf stability and stain removal properties. The thickening agent may include a cellulosic or clay material, starch, gum, fatty acid, fatty alcohol, hydrophilic colloidal particles, polyoxyethylene glycol or polyoxyethylene glycol derivatives including fatty acid esters and ethers, or a combination thereof.
