FIELD OF INVENTION

The present application relates to care agents, for example care polymers, and compositions such as consumer products comprising such care agents, as well as processes for making and using such care agents and such compositions.

BACKGROUND OF THE INVENTION

Care polymers, including silicones, are used in premium consumer products to provide benefits such as softness, hand, anti-wrinkle, hair conditioning/frizz control, color protection, etc. Unfortunately, such care polymers are incompatible with a variety of other consumer product ingredients, for example, anionic surfactants, and/or are expensive due to the cost of silicone raw materials and the silicone emulsification step that is required to make such silicones useful in products. Thus, what is needed is an economical, stable care polymer technology with reduced incompatibility issues.

Fortunately, Applicants recognized that the source of the incompatibility and stability issues was the charge of current care polymers and such polymers' stiffness as due to such polymers' high glass transition temperature. Thus, Applicants discovered that by judiciously selecting or synthesizing care polymers that have the correct charge and glass transition temperature, the incompatibility and stability issues could be resolved and yet the required performance can be economically obtained. The performance of the care polymers that Applicants teach, can be further increased by following the emulsification teachings of the present specification and/or by combining such care polymers with silicone materials.

SUMMARY OF THE INVENTION

The present application relates to care agents, for example, care polymers and compositions such as consumer products comprising such care agents, as well as processes for making and using such care agents and such compositions.

Suitable perfume microcapsules may include those described in the following references: published USPA Nos 2003-215417 A1; 2003-216488 A1; 2003-158344 A1; 2003-165692 A1; 2004-071742 A1; 2004-071746 A1; 2004-072719 A1; 2004-072720 A1; 2003-203829 A1; 2003-195133 A1; 2004-087477 A1; 2004-0106536 A1; U.S. Pat. Nos. 6,645,479; 6,200,949; 4,882,220; 4,917,920; 4,514,461; RE32713; 4,234,627; EP 1393706 A1. Capsules having a perfume loading of from about 50% to about 95% by weight of the capsule may be employed.

The shell material surrounding the core to form the microcapsule can be any suitable polymeric material which is impervious or substantially impervious to the materials in the core (generally a liquid core) and the materials which may come in contact with the outer surface of the shell. In one aspect, the material making the shell of the microcapsule may comprise formaldehyde. Formaldehyde based resins such as melamine-formaldehyde or urea-formaldehyde resins are especially attractive for perfume encapsulation due to their wide availability and reasonable cost.

One method for forming shell capsules useful herein is polycondensation, which may be used to produce aminoplast encapsulates. Aminoplast resins are the reaction products of one or more amines with one or more aldehydes, typically formaldehyde. Non-limiting examples of amines are melamine and its derivatives, urea, thiourea, benzoguanamine, and acetoguanamine and combinations of amines. Suitable cross-linking agents (e.g. toluene diisocyanate, divinyl benzene, butane diol diacrylate, etc) may also be used and secondary wall polymers may also be used as appropriate, as described in the art, e.g., anhydrides and their derivatives, particularly polymers and copolymers of maleic anhydride as disclosed in published USPA 2004-0087477

A1.

Microcapsules having the liquid cores and polymer shell walls as described above can be prepared by any conventional process which produces capsules of the requisite size, friability and water-insolubility. Generally, such methods as coacervation and interfacial polymerization can be employed in known manner to produce microcapsules of the desired characteristics. Such methods are described in Ida et al, U.S. Pat. Nos. 3,870,542; 3,415,758; and 3,041,288.

Cyclodextrin. A suitable moisture-activated perfume carrier that may be useful in the disclosed multiple use fabric conditioning composition may comprise cyclodextrin. As used herein, the term “cyclodextrin” includes any of the known cyclodextrins such as unsubstituted cyclodextrins containing from six to twelve glucose units, especially beta-cyclodextrin, gamma-cyclodextrin, alpha-cyclodextrin, and/or derivatives thereof, and/or mixtures thereof. A more detailed description of suitable cyclodextrins is provided in U.S. Pat. No. 5,714,137. Suitable cylodextrins herein include beta-cyclodextrin, gamma-cyclodextrin, alpha-cyclodextrin, substituted beta-cyclodextrins, and mixtures thereof. In one aspect, the cyclodextrin may comprise beta-cyclodextrin. Perfume molecules are encapsulated into the cavity of the cyclodextrin molecules to form molecular microcapsules, commonly referred to as cyclodextrin/perfume complexes. The perfume loading in a cyclodextrin/perfume complex may comprise from about 3% to about 20%, or from about 5% to about 18%, or from about 7% to about 16%, by weight of the cyclodextrin/perfume complex.

The cyclodextrin/perfume complexes hold the encapsulated perfume molecules tightly, so that they can prevent perfume diffusion and/or perfume loss, and thus reducing the odor intensity of the multiple use fabric conditioning composition. However, the cyclodextrin/perfume complex can readily release some perfume molecules in the presence of moisture, thus providing a long lasting perfume benefit. Non-limiting examples of preparation methods are given in U.S. Pat. Nos. 5,552,378, and 5,348,667.

Suitable cyclodextrin/perfume complexes (or perfume cyclodextrin microcapsule) may have a small particle size, typically from about 0.01 to about 200 micrometer, or from about 0.1 less than about 150 micrometer, or from about 1.0 to about 100 micrometer, or from about 10 to about 50 micrometer.

The multiple use fabric conditioning compositions may comprise of from about 0.1% to about 25%, or from about 1% to about 20%, or from about 3% to about 15%, or from about 5% to about 10%, by weight of the total fabric conditioning composition, of cyclodextrin/perfume complex.

Moisture-Activated Cellular Matrix Microcapsule Moisture-activated and/or water-soluble perfume cellular matrix microcapsules are solid particles containing perfume stably held in the cells within the particles. Details about moisture-activated perfume cellular matrix microcapsules are disclosed in U.S. Pat. No. 3,971,852. A suitable moisture-activated perfume cellular matrix microcapsule may be perfume starch microcapsule which uses starch as the cellular matrix material.

Moisture-activated perfume cellular matrix microcapsules may have a size of from about 0.5 micron to about 300 microns, from about 1 micron to about 200 microns, or from about 2 microns to about 100 microns. The perfume loading in the cellular matrix microcapsules may range from about 20% to about 70%, or from about 40% to about 60%, by weight of the microcapsules. Sufficient amount of perfume moisture-activated microcapsules should be used to deliver the desired levels of perfume, depending on the perfume loading of the microcapsules. For microcapsules with a perfume loading of about 50%, typical level of the matrix microcapsules may comprise from about 0.1% to about 15%, from about 0.5% to about 7%, from about 0.8% to about 8%, or from about 1% to about 6%, by weight of the multiple use fabric conditioning composition.

A dispersing agent may be used to distribute the moisture-activated perfume cellular matrix microcapsules uniformly in the molten multiple use fabric conditioning composition. Suitable dispersing agents for use in combination with moisture-activated cellular microcapsules include block copolymer having blocks of terephthalate and polyethylene oxide. More specifically, these polymers are comprised of repeating units of ethylene and/or propylene terephthalate and polyethylene oxide terephthalate at a molar ratio of poly(ethylene/propylene) terephthalate units to polyethylene oxide terephthalate units of from about 25:75 to about 35:65, said polyethylene oxide terephthalate containing polyethylene oxide blocks having molecular weights of from about 300 to about 2,000. The molecular weight of this polymeric dispersing agent may be in the range of from about 5,000 to about 55,000.

Another suitable dispersing agent for use in combination with moisture-activated cellular microcapsules may be block copolymer having blocks of polyethylene oxide and of polypropylene oxide. Non-limiting examples of dispersing agent of this type include Pluronic® surfactants and Tetronic® surfactants.

In the process of preparing a multiple use fabric conditioning bar, a suitable dispersing agent may first be added to the fabric conditioning composition melt mixture with mixing, and the moisture-activated perfume starch microcapsules may then be added to the melt mixture with mixing, and the resulting mixture may be poured into a mold to form a multiple use fabric conditioning bar.

Porous Carrier Microcapsule—A portion of the perfume composition can also be absorbed onto and/or into a porous carrier, such as zeolites or clays, to form perfume porous carrier microcapsules in order to reduce the amount of free perfume in the multiple use fabric conditioning composition. When the perfume is to be adsorbed onto zeolite, the perfume ingredients forming the encapsulated perfume composition can be selected according to the description provided in U.S. Pat. No. 5,955,419.

Pro-perfume—The perfume composition may additionally include a pro-perfume. Pro-perfumes may comprise nonvolatile materials that release or convert to a perfume material as a result of, e.g., simple hydrolysis, or may be pH-change-triggered pro-perfumes (e.g. triggered by a pH drop) or may be enzymatically releasable pro-perfumes, or light-triggered pro-perfumes. The pro-perfumes may exhibit varying release rates depending upon the pro-perfume chosen. Pro-perfumes suitable for use in the disclosed compositions are described in the following: U.S. Pat. Nos. 5,378,468; 5,626,852; 5,710,122; 5,716,918; 5,721,202; 5,744,435; 5,756,827; 5,830,835; and 5,919,752.
