Esters

A method of reducing dye loss during the laundry treatment of dyed fabrics using a laundry treatment composition comprising a water-soluble or water-dispersible rebuild agent for deposition onto a fabric during a treatment process wherein the material undergoes during the treatment process, a chemical change by which change the affinity of the material for the fabric is increased.

Laundry treatment for fabrics

Treatment for substrates

Cellobiose esters and particularly &agr; cellobiose octanonanoate has been found able to structure water-immiscible liquids well, and in particular can produce clear structured emulsions. However, such emulsions tend to lose clarity or structural strength during storage. Deviating from &agr;-cellobiose octanonanoate can result in impaired clarity and/or impaired hardness of emulsion sticks. However, acylated cellobiose which contains acyl substituents of formula &mdash;O&mdash;CO&mdash;R in which R represents an n-octyl residue and the percentage Y of the nonanoate acyl substituent &mdash;O&mdash;CO&mdash;R at the anomeric carbon is at least 60% and the percentage A of &agr; anomer is greater than the anomer and not higher than A&equals;74.5 &plus;0.2Y when Y is up to 92% and not higher than A&equals;161&minus;0.74Y when Y is greater than 92% offers the production of sticks combining structurant stability with product clarity and hardness.

A laundry treatment composition comprising a water-soluble or water-dispersible rebuild agent for deposition onto a fabric during a treatment process wherein the material undergoes during the treatment process, a chemical change by which change the affinity of the material for the fabric is increased.

A fabric rebuild polymer comprising a cellulose or other &bgr;-1,4 linked polysaccharide backbone with acetate groups pendant thereto, the average degree of substitution of acetate groups on the saccharide groups of the backbone being 0.55-0.70, with a molecular weight in the range 12,000-20,000 gives particularly effective fabric rebuild effect in a laundry treatment process at a pH in the range 9.5-11.0.

Laundry treatment compositions, especially detergent compositions or rinse conditioners, which deposit cellulosic polymers or related polysaccharide fabric rebuild agents onto textile fabrics are described. Such agents are used for laundering cellulosic fabrics such as cotton, to compensate for gradual loss of fibrous material on repeated washing. Preferred rebuild agents are cellulose monoacetate, cellulose hemisuccinate and other cellulose esters.

Treatment for fabrics

A cosmetic composition contains a water-immiscible carrier liquid and a structurant therefor which is effective to gel the composition upon cooling from a temperature at which the structurant is a mobile solution in the carrier liquid. The carrier liquid may serve as a continuous phase in which a solid or liquid disperse phase is suspended. The structurant is a fully or partially esterified saccharide which contains no more than eight monosaccharide residues and has an enthalpy of gelation in the carrier liquid with a magnitude of at least 45 kJ/mole. This minimum enthalpy of gelation facilitates processing at conveniently accessible temperatures and promotes stability.

Cosmetic compositions

A fiber rebuild polymer comprising a cellulose or other &bgr;-1,4 linked polysaccharide backbone with acetate groups pendant thereto, the average degree of substitution of acetate groups on the saccharide groups of the backbone being 0.55-0.70, is used to inhibit wrinkling and improve ironability of cloth during a laundry process.

A cosmetic composition is a structured emulsion of a continuous phase containing water-immiscible liquid carrier plus a structurant, and a disperse phase which is a solution of antiperspirant active in a more polar, probably aqueous, solvent. The structurant is a material which forms a network of fibers in the continuous phase, thereby gelling it. The structurant has an enthalpy of gelation in the carrier liquid or a test liquid with a magnitude of at least 30 kJ/mole. This minimum enthalpy of gelation facilitates processing at conveniently accessible temperatures and promotes stability.

A laundry treatment composition comprising peroxygen bleach and a water-soluble or water dispersible rebuild agent for redeposition onto a fabric during the laundry process, wherein the fabric rebuild agent undergoes during the laundry process, a chemical change by which change the affinity of the material for the fabric is increased. The peroxygen bleach was found to increase the deposition of the fabric rebuild agent.
