Definitions

  • the present invention relates to the use of cationic celluloses to enhance deposition of water insoluble fabric care benefit agents such as dispersible polyolefins and latexes during laundering.
  • Laundering textiles is a necessity in order to remove stains, odors and soils.
  • textiles can undergo mechanical and chemical damage which can result in fabric wrinkles, color fading, dye transfer, pills/fuzz, fabric wear, fiber deterioration, stiffness, and other undesirable consumer issues. Therefore, many laundry products such as detergents, fabric conditioners, and other wash, rinse, and dryer added products, frequently include one or more fabric care benefit agents that are added in an attempt to reduce or prevent these consumer issues.
  • fabric care benefit agents often provide limited benefits due to poor delivery efficiency on the fabrics or textiles during the laundering process.
  • the affinity between these fabric care agents and fabrics/garments is typically very limited due to the lack of natural attractive forces between the fabric care agents and the fabrics. This is because most fabric care agents used in laundry products are formulated to be anionic or nonionic in order to avoid interaction with anionic surfactants which might lead to potential cleaning negatives. Since most textile fibers such as cotton, wool, silk, nylon, and the like carry a slightly anionic charge in the laundry solution, there are repulsive instead of attractive forces between the fabric care agent and the fabric resulting in poor delivery efficiency.
  • water insoluble fabric care benefit agents examples of which include but are not limited to, dispersible polyolefins, polymer latexes and the like. Due to their water insolubility, water insoluble fabric care benefit agents are generally incorporated into laundry product formulations in some type of water stable form such as an emulsion, a latex, a dispersion, a suspension, or the like. When added to the laundry product in a water stable form, the water insoluble fabric care benefit agent becomes even more stable in solution. This is due to the existence of large amounts of surfactant that are present in laundry products.
  • the surfactant in the laundry products tends to act as an emulsifying agent, dispersion agent, suspension agent, or the like thereby resulting in the further stabilization of the emulsion, dispersion, and/or suspension containing the water insoluble fabric care benefit agent.
  • the affinity of the water insoluble fabric care benefit agent for the fabric is severely limited.
  • the majority of the water insoluble fabric care benefit agent tends to stay in solution wherein it is discarded with the wash solution thereby limiting the amount of benefit agent available for deposition on the fabric.
  • the laundry products of the present invention comprise at least one water insoluble fabric care benefit agent and at least one cationic cellulose delivery enhancing agent or deposition aid.
  • laundry products of the present invention improve the fabric delivery efficiency of water insoluble fabric care benefit agents that are incorporated therein by the inclusion of the cationic cellulose delivery agents of the present invention. It has surprisingly been found that by using cationic celluloses as delivery enhancing agents, the delivery of the water insoluble fabric care benefit agent to the fabric is significantly enhanced, which would not otherwise be possible.
  • the cationic celluloses may provide fabric care benefits by themselves, an amount of the cationic celluloses needed to deliver significant performance benefits is much larger than an amount of the cationic celluloses needed as a delivery enhancing agent.
  • large amounts of cationic celluloses often have a negative affect on cleaning performance. The cleaning negative caused by the large amount of cationic celluloses will normally prohibit their application in laundry detergent embodiments as the benefit agents alone.
  • the level of the cationic cellulose as the delivery enhancing agent the impact on cleaning is normally very limited.
  • the addition of the cationic celluloses of the present invention into laundry products may provide significant improvement in the delivery/deposition of the water insoluble fabric care benefit agent on the fabric versus utilizing the water insoluble fabric care benefit agent alone.
  • a laundry detergent containing cationic celluloses and the fabric care benefit agent are added in the washer, delivery/deposition enhancements of the water insoluble fabric care benefit agent on fabric of as much as 5 to 10 timers the normal amount of benefit agent alone are observed.
  • the delivery/deposition enhancements may be accomplished by mixing the cationic cellulose and the fabric care benefit agent together as a laundry additive of a fabric care composite or by formulating these two ingredients into laundry detergent or other laundry products.
  • the present invention relates to the use of cationic cellulose to enhance deposition of water insoluble fabric care benefit agents including dispersible polyolefins and latexes during laundering.
  • utilizing the cationic cellulose delivery enhancing agents of the present invention allows for improved delivery of the water insoluble fabric care benefit agent to the fabric so as to provide enhanced fabric softening color protection, pill/fuzz reduction, anti-abrasion, anti-wrinkle, and other such benefits to garments and textiles.
  • the cationic cellulose, called the delivery enhancing agent, and the water insoluble fabric care benefit agent of the present invention may be mixed together prior to formulating in, adding to, or using in conjunction with a laundry product composition.
  • the two components may be formulated into laundry products separated with different orders of addition.
  • the two components of the present invention may also be mixed together in situ after addition to the laundry product composition. Additionally, the two components of the present invention may be applied directly to the fabric together or separately.
  • the deposition of the water insoluble fabric care benefit agent on the fabric is significantly improved and in some instances doubled, (i.e.; utilizing the delivery enhancing agent of the present invention may increase the deposition of the water insoluble fabric care benefit agent on the fabric by potentially about 100% or more compared with using the water insoluble fabric care benefit agent alone).
  • deposition on the fabric will increase by at least about 200%. Since the fabric care benefit is directly related to the amount of deposition of the fabric care benefit agent on the fabric, the performance of the water insoluble fabric care benefit agent on the fabric should theoretically increase proportionately by potentially about 100% and preferably by at least about 200%.
  • the ratio of the delivery enhancing agent to the water insoluble fabric care benefit agent should be from about 1:50 to 1:1 and preferably from about 1:20 to 1:2.
  • the two components of the present invention can be premixed to form a stable composite prior to formulating into a laundry product or prior to adding to the laundry process or applying to a fabric.
  • the two components can also be formulated into laundry products separately with different orders of addition.
  • the two components may also be mixed together so as to form the fabric care composite of the present invention in situ after formulating into the laundry product or adding to the laundry process.
  • delivery enhancing agent refers to any cationic cellulose or combination of cationic celluloses that significantly enhance the deposition of the water insoluble fabric care benefit agent onto the fabric during laundering.
  • the delivery enhancing agent of the present invention has a strong physical binding capability with the water insoluble fabric care benefit agent. It also has a very strong affinity to natural textile fibers, such as cotton fibers.
  • An effective delivery enhancing agent preferably has a strong binding capability with the water insoluble fabric care benefit agents via physical forces such as van der Waals forces or non-covalent chemical bonds such as hydrogen bonding and/or ionic bonding. It preferably has a very strong affinity to natural textile fibers, particularly cotton fibers.
  • the delivery enhancing agent should be water soluble and have a flexible molecular structure so that it can cover the water insoluble fabric care benefit agent particle surface or hold several particles together. Therefore, the delivery enhancing agent is preferably not cross-linked and preferably does not have a network structure as these both tend to lack molecular flexibility.
  • the net charge of the deliver enhancing agent is preferably positive in order to overcome the repulsion between the fabric care benefit agent and the fabric since most fabrics are comprised of textile fibers that have a slightly negative charge in aqueous environments.
  • fibers exhibiting a slightly negative charge in water include but are not limited to cotton, rayon, sink, wool, etc.
  • the delivery enhancing agent is a cationic or amphoteric polymer.
  • the amphoteric polymers will also have a net cationic charge, i.e.; the total cationic charges on these polymers will exceed the total anionic charge.
  • the degree of substitution of the cationic charge can be in the range of from about 0.01 (one cationic charge per 100 polymer repeating units) to 1.00 (one cationic charge on every polymer repeating unit) and preferably from about 0.01 to 0.20,
