Description

  The present invention relates to the use of cationic celluloses to improve the adhesion of water insoluble fabric care benefit agents such as dispersible polyolefins and latices during laundering.

  Textile washing is essential to remove stains, odors, and dirt. However, fabrics can suffer mechanical and chemical damage during the washing process, and this damage can be caused by fabric wrinkles, discoloration, dyeing, fuzz / fluffing, fabric fraying, fiber degradation, stiffness. ), And other undesirable consumer problems. As such, many laundry products, such as detergents, fabric conditioners, and other wash, rinse, and dryer additive products, often include one or more fabrics that are added to reduce or avoid these consumer problems. Contains a care benefit agent.

  However, the benefits provided by such fabric care benefit agents are often limited due to poor delivery efficiency to the fabric or fabric during the laundry process. The affinity between these fabric care agents and fabric / garments is usually very limited because there is no natural attraction between the fabric care agent and the fabric. This ensures that most fabric care agents used in laundry products become anionic or nonionic in order to avoid interaction with anionic surfactants that can lead to potential drawbacks of cleaning. It is because it is mix | blended with. Most textile fibers, such as cotton, wool, silk, nylon, etc., have a slightly anionic charge in the wash solution, creating a repulsive force rather than an attractive force between the fabric care agent and the fabric, Delivery efficiency will be reduced.

  This is particularly true for water insoluble fabric care benefit agents, examples of such benefit agents include, but are not limited to, dispersible polyolefins, polymer latexes, and the like. Water insoluble fabric care benefit agents are generally incorporated into laundry product formulations in some form that is water stable, such as emulsions, latexes, dispersions, suspensions, etc., because they are water insoluble. This water insoluble fabric care benefit agent becomes more stable in solution when added to a laundry product in a water stable form. This is due to the presence of large amounts of surfactant present in the laundry product. Surfactants in laundry products act as emulsifiers, dispersants, suspending agents, etc., thereby further stabilizing emulsions, dispersions, and / or suspensions containing water-insoluble fabric care benefit agents. Tend to bring about. This stabilization results in a very limited affinity of the water-insoluble fabric care benefit agent for the fabric. Since most of the water-insoluble fabric care benefit agent tends to remain in solution and is discarded with the cleaning solution, the amount of benefit agent effective for attachment to the fabric is limited.

  Accordingly, there is a need to improve the fabric delivery efficiency of water insoluble fabric care benefit agents incorporated into laundry products.

  The laundry product of the present invention comprises at least one water-insoluble fabric care benefit agent and at least one cationic cellulose delivery enhancer or deposition aid.

  Without being limited by theory, it is believed that the laundry product of the present invention improves the fabric delivery efficiency of the water-insoluble fabric care benefit agent incorporated into the laundry product by including the cationic cellulose delivery agent of the present invention. Yes. Surprisingly, it has been found that the use of cationic celluloses as delivery enhancers provides a significant improvement in the delivery of water-insoluble fabric care benefit agents to fabrics, which was otherwise impossible. It was issued.

  Although cationic celluloses alone can provide fabric care benefits, the amount of cationic cellulose required to deliver significant performance benefits is that of the cationic celluloses required as a delivery enhancer. Much more than quantity. However, large amounts of cationic cellulose often have an adverse effect on cleaning performance. In general, laundry detergent embodiments do not utilize cationic celluloses alone as a benefit agent because of the disadvantages of washing caused by high amounts of cationic celluloses. Importantly, however, if the concentration of cationic cellulose is that of a delivery enhancer, the effect on washing is usually very limited.

  Even more surprisingly, when the cationic celluloses of the present invention are added to laundry products, the delivery / adhesion of the water-insoluble fabric care benefit agent to the fabric is greater than when the water-insoluble fabric care benefit agent is used alone. It has been found that significant improvements can be made. When a laundry detergent containing cationic celluloses and a fabric care benefit agent is added to the washing machine, it delivers 5-10 times more water-insoluble fabric care benefit agent to the fabric than with a normal amount of benefit agent alone. It is actually surprising that it is found that an improved adhesion is observed.

  This improved delivery / adhesion can be achieved by mixing the cationic cellulose and the fabric care benefit agent as a laundry additive in the fabric care composite, or by blending these two ingredients into a laundry detergent or other laundry product. It is also surprising that it is found that this can be achieved.

Water insoluble benefit agents useful herein include dispersible polyolefins and polymer latices. The water-insoluble fabric care benefit agent preferably has a particle size of about 1 nm to 100 μm. The present invention also includes a detergent or fabric softening composition, the composition comprising:
a. About 1 to 80% by weight of an anionic, cationic, non-ionic, amphoteric, bipolar surfactant, or combinations thereof;
b. About 0.1 to 10% by weight of a water-insoluble benefit agent, wherein the water-insoluble fabric care benefit agent is an emulsion of polyolefin, latex, or a mixture thereof;
c. Contains about 0.01-2% cationic cellulose.

  Preferably, the ratio of delivery enhancer to fabric care benefit agent is from about 1:50 to about 1: 1.

  The present invention relates to the use of cationic celluloses to improve the adhesion of water insoluble fabric care benefit agents, including dispersible polyolefins and latices during laundering. Without being limited by theory, the use of the cationic cellulose delivery enhancer of the present invention improves the delivery of water-insoluble fabric care benefit agents to fabrics, allowing fabric softening, color protection, Provides reduced fuzz / fluffing, wear protection, wrinkle prevention, and other similar benefits.

  The cationic cellulose, referred to as delivery enhancer, and the water-insoluble fabric care benefit agent of the present invention are mixed and then blended into the laundry product composition, added to the laundry product composition, or the laundry product composition and You may use together. These two components may be blended separately into the laundry product in various order of addition. Also, these two components of the present invention may be mixed in situ after addition to the laundry product composition. Furthermore, these two components of the present invention may be applied directly to the fabric, either simultaneously or separately.

  By using the delivery enhancer of the present invention, the adhesion of the water-insoluble fabric care benefit agent to the fabric is greatly improved and in some cases doubled (ie, using the delivery enhancer of the present invention, The adhesion of the water-insoluble fabric care benefit agent to the fabric can be increased by about 100% or more compared to using the water-insoluble fabric care benefit agent alone). Preferably, the adhesion to the fabric is increased by at least about 200%. Since fabric care benefits are directly related to the amount of fabric care benefit agent attached to the fabric, the performance of the water-insoluble fabric care benefit agent on the fabric can theoretically increase approximately 100% proportionally; Preferably it should increase by at least about 200%.

  The ratio of delivery enhancer to water insoluble fabric care benefit agent should be about 1:50 to 1: 1, preferably about 1:20 to 1: 2. These two components of the present invention can be premixed to form a stable composite and then blended into a laundry product or added to a laundry process or applied to a fabric. These two components can also be blended separately into the laundry product in various order of addition. These two components may also be mixed after blending into a laundry product or after addition to the laundry process to form the fabric care composite of the present invention in situ.

  All percentages, ratios and proportions herein are on a weight basis unless otherwise indicated. All documents cited herein are hereby incorporated by reference.

Should. Thus, delivery enhancers are preferably not cross-linked and preferably do not have a network structure because both tend to be poor in molecular flexibility.

  Because most fabrics are composed of textile fibers that have a slightly negative charge in an aqueous environment, repelling force between the fabric care benefit agent and the fabric is necessary to advance the fabric care benefit agent to the fabric. It is preferred that the net charge of the delivery enhancer is positive so as to overcome. Examples of fibers that exhibit a slightly negative charge in water include, but are not limited to, cotton, rayon, silk, wool, and the like.
