Definitions

  • the present invention relates to laundry detergent compositions comprising a semi-polar nonionic surfactant and certain cyclic amine based polymer, oligomer or copolymer materials and other detergent components including a builder compound.
  • Short fibers are dislodged from woven and knit fabric/textile structures by the mechanical action of laundering. These dislodged fibers may form lint, fuzz or "pills" which are visible on the surface of fabrics and diminish the appearance of newness of the fabric. Further, repeated laundering of fabrics and textiles, especially with bleach-containing laundry products, can remove dye from fabrics and textiles and impart a faded, worn out appearance as a result of diminished color intensity, and in many cases, as a result of changes in hues or shades of color.
  • the fabric care cationic cyclic amine based polymers are not highly compatible with the high levels of anionic surfactants usually formulated within the conventional laundry detergent compositions. It has been found further that those anionic surfactants significantly decrease the efficiency of such cyclic amine based compounds. Such high levels of anionic surfactants are generally used to provide good cleaning properties. Therefore, in order to formulate compositions with such cationic cyclic amine based polymers, detergent compositions have been formulated without anionic surfactants but with nonionic surfactants. However, it has been found that detergent compositions with a high level of nonionic surfactants do not provide the same cleaning performance as comparable high level of anionic surfactants and are more difficult to formulate, especially at high electrolyte content.
  • the object of the present invention is therefore to formulate a laundry detergent composition which provide excellent cleaning properties together with excellent fabric care benefits. It has been surprisingly found that the combination of a semi-polar nonionic surfactant with the above mentioned cationic cyclic amine based polymer provide both excellent cleaning properties together with excellent fabric care benefits.
  • compositions of the present invention demonstrate high physical stability when formulated in a liquid form.
  • DE-A-2750777 discloses bubble bath compositions which contain semi-polar nonionic surfactants such as amine oxides and cationic nitrogen-containing polymers derived from cyclic moieties with two nitrogen atoms.
  • US-A-3917817 and US-A-4013787 disclose hair treating compositions, e.g., shampoos, containing film-forming polymers based on piperazine and, in some instances, also containing amine oxide surfactants.
  • WO-A-98/17762 discloses polycationic condensation products based on piperazines, imidazoles and their derivatives in combination with nonionic tensides in preferably anionic surfactant-free detergent compositions and in fabric "after-treatment agents.”
  • the present invention is directed to laundry detergent compositions free of anionic surfactants comprising a semi-polar nonionic surfactant, a cyclic amine based polymer, oligomer or copolymer and a conventional laundry detergent component as defined in claim 1.
  • anionic surfactants comprising a semi-polar nonionic surfactant, a cyclic amine based polymer, oligomer or copolymer and a conventional laundry detergent component as defined in claim 1.
  • Such compositions provide good cleaning performance as well as the desired fabric appearance and integrity benefits.
  • the cyclic amine based polymer, oligomer or copolymer is characterized by the following formula as defined below.
  • the present invention relates to the laundering of fabrics and textiles in aqueous washing or treating solutions formed from effective amounts of the detergent compositions described herein, or formed from the individual components of such compositions.
  • Laundering of fabrics and textiles in such washing solutions, followed by rinsing and drying, imparts fabric cleaning as well as fabric appearance benefits to the fabric and textile articles so treated.
  • fabric care benefits can include improved overall appearance, pill/fuzz reduction, antifading, improved dye transfer inhibition, improved abrasion resistance, and/or enhanced softness.
  • the laundry detergent compositions of the present invention are free of anionic surfactants, and comprise a cyclic amine based polymer and an amine oxide surfactants and provide excellent cleaning properties together with excellent fabric care benefits.
  • the compositions also contain conventional laundry detergent components as defined in claim 1.
  • the semi-polar nonionic surfactants by their chemical nature, introduce some 'hidden' anionic character. Therefore, those semi-polar nonionic surfactants so provide good cleaning properties while not interacting with the cationic polymers, thereby providing excellent fabric cleaning and fabric care properties.
  • semi-polar nonionic surfactants act as hydrotropes within compositions of the present invention, when formulated in the liquid form.
  • high levels of nonionic surfactants within liquid compositions lead to phase separation.
  • the semi-polar nonionic surfactants of the present invention act as hydrotropes and reduce greatly phase separation.
  • These semi-polar nonionic surfactants therefore are found to facilitate the formulation of high nonionic detergent compositions and to increase the physical stability of liquid products. This allows to formulate laundry detergent compositions comprising a high level of nonionic surfactants, which are perfectly fluid isotropic liquids.
  • the first essential element of the laundry detergent compositions of the present invention is the cyclic amine based polymer, oligomer or copolymer as described hereinafter:
  • the first essential component of the compositions of the present invention is one or more cyclic amine based polymer, oligomer or copolymer.
  • Such materials have been found to impart a number of appearance benefits to fabrics and textiles laundered in aqueous washing solutions formed from detergent compositions which contain such cyclic amine based fabric treatment materials.
  • Such fabric appearance benefits can include, for example, improved overall appearance of the laundered fabrics, reduction of the formation of pills and fuzz, improved dye transfer inhibition, protection against color fading, improved abrasion resistance, etc.
  • the combination of semi-polar nonionic surfactants with the cyclic amine based fabric treatment materials used in the compositions and methods according to the present invention can provide such fabric appearance benefits while maintaining good cleaning performance.
  • the cyclic amine based polymer, oligomer or copolymer component of the compositions herein may comprise combinations of these cyclic amine based materials.
