摘要:
Disclosed are stabilized body care products, household products, textiles and fabrics which comprise certain hindered nitroxyl, hydroxylamine and hydroxylamine salt compounds. Dyed products and articles are effectively stabilized against color degradation. The products are for example skin-care products, hair-care products, dentifrices, cosmetics, laundry detergents and fabric softeners, non-detergent based fabric care products, household cleaners and textile-care products.

Carboxylated, mercerized cellulose fiber having at least 12 meq/100 g of carboxyl substitution at the C-6 position of the anhydroglucose units, which includes at least 20% cellulose II, may be produced by catalytically carboxylating mercerized cellulose fiber in at least two catalytic carboxylation stages in a continuous series in which the pH is adjusted, and a primary oxoammonium salt catalyst (or precursor thereof) and secondary oxidant is added, at the beginning of each stage. Optionally, the carboxylated, mercerized cellulose may be made substantially free of aldehyde groups by means of a stabilizing step following the final carboxylation stage, in which aldehyde groups present in the fibers are converted to carboxyl groups.
摘要:
Alkali surfactant compositions and treatment processes. The alkali surfactant composition has a surface tension (at 100 ms) of from [0.8 asymptote] to [1.2 * asymptote]. The composition can be used in treatment processes, such as cleaning, chemical pulping, mercerization, metal processing, leather processing, food processing, and personal beauty care. The process comprises the step of contacting a substrate with an effective amount of an aqueous alkali surfactant composition having a hydroxide Molarity of from 2 to 9. The composition comprises (a) alkali; and (b) a surfactant having a Lewis acid head group positioned terminally in a linear or branched aliphatic hydrocarbon chain comprising from 4 to 10 aliphatic carbon atoms.

The present invention relates to a method of obtaining a solid material based on a polymer having its cellobiose units exhibiting the following characteristics: at least some of the cellobiose units have at least one carboxylic acid function attached to the C6 carbon, the other C6 carbons having a primary alcohol function attached thereto; and at least some of the cellobiose units have at least one of the two rings open between the C2 and C3 carbons, the other C2 and C3 carbons forming a ring and having an alcohol function attached thereto. Such a material, advantageously a textile, may be used as a compress.

Disclosed are stabilized body care products, household products, textiles and fabrics which comprise certain hindered nitroxyl, hydroxylamine and hydroxylamine salt compounds and selected organic UV filters. The stabilized products are for example skin-care products, hair-care products, dentifrices, cosmetics, laundry detergents and fabric softeners, non-detergent based fabric care products, household cleaners and textile-care products.
摘要:
A fabric treatment composition that includes at least one zeta potential modifier and a hydrophobic agent with a melting point or glass transition temperature below 100° C. that imparts fabric protection benefits, including improved stain resistance, oil repellency, water repellency, softness, wrinkle and damage resistance, and better handfeel to treated fabrics. Particularly preferred compositions include at least one zeta potential modifier in an amount sufficient to adjust the zeta potential of the composition to be positive and greater than zero millivolts. Particularly preferred compositions also include a fluoropolymer. The composition can be used as a pretreatment prior to washing, through soaking or direct spray application, or added to the wash or rinse cycle of an automatic washing machine, or used prior to or during the drying cycle of an automatic drying machine or refresher machine, or used prior to or in conjunction with an ironing device. The fabric treatment is complete when the fabric is cured by drying and/or heating.
