Silicone elastomer compositions

Abstract

This invention related to silicone elastomer compositions in the form of gels and/or organized structures. The silicone elastomer compositions are produced by reacting a siloxane having a first reactive group with a crosslinker having a second reactive group in a diluent. One reactive group is selected from epoxy-functional groups or chlorohydrin functional groups while the other reactive group is a functional group that reacts with epoxy-functional groups or chlorohydrin functional groups (i.e. amine, hydroxyl). The silicone elastomer compositions of the instant invention are particularly useful in personal care products, textiles, auto care products, and laundry products and for the delivery of active ingredients.

Description

FIELD OF THE INVENTION

[0002] This invention relates to silicone elastomer compositions in the form of gels and/or organized structures.

BACKGROUND OF THE INVENTION

[0003] In personal care formulations it has become desirable to use low viscosity silicones to impart a number of benefits to the formulation. However, because of the addition of the low viscosity silicone, there must be additionally added a thickener to the personal care formulation. Certain silicone polymers have found utility as the thickening agent because they can be used in the quantities necessary to thicken the composition without degrading the properties of the personal care formulation. Typically, the silicone polymer and low viscosity silicone are combined to form a paste. This paste can then be used in the personal care formulation. Such silicone polymers are described in U.S. Pat. No. 4,987,169 to Kuwata et al., U.S. Pat. No. 5,760,116 to Kilgour et al., U.S. Pat. No. 5,811,487 to Schulz, Jr. et al. and U.S. Pat. No. 5,889,108 to Zhang and U.S. Pat. No. 6,238,657 to Lin et al..

[0004] This invention pertains to functionalized silicone elastomer compositions that are in the form of gels and/or organized structures. These functionalized silicone elastomer compositions are particularly useful in personal care formulations.

[0091] In the above list of perfume ingredients, some are commercial names conventionally known to one skilled in the art, and also includes isomers. Such isomers are also suitable for use in the present invention.

[0092] Other active ingredients which can be carried in a phase(s) of the silicone fluid or nonpolar organic compound include, but are not limited to vitamins and drugs among which are vitamin A, RETINOL, C2-C18 esters of RETINOL, vitamin E, tocopherol, esters of vitamin E, retinyl acetate, retinyl palmitate, retinyl propionate, α-tocopherol, tocophersolan, tocopheryl acetate, tocopheryl linoleate, tocopheryl nicotinate, tocopheryl succinate, and mixtures thereof. These active ingredients are described in U.S. Pat. No. 5,948,855, herein incorporated by reference for its teaching of these actives.

[0093] Optionally, there may be present a compound (VI) that introduces functional groups, F, into the silicone elastomer (“functional compound”) wherein F is as described above. The functional compound may be silicone, organic. It may be reactive with the siloxane (I) and/or crosslinker (II) resulting in functionality that is bonded directly to the silicone elastomer. It may be unreactive resulting in functionality that is in the silicone elastomer composition. The functional compound can be added before, during or after the crosslinking reaction. Combinations of functional compounds can be used or combinations of functionality may be used so long as the functional compound does not substantially interfere with the crosslinking chemistry.

[0094] The silicone elastomer compositions are prepared by combining the siloxane (1), crosslinker (II) and diluent (III). No special equipment or processing conditions are generally required. Heat and agitation may be applied to facilitate the crosslinking reaction. Typically, the reaction mixture is heated to 25 to 100° C. Simple propeller mixers, turbine-type mixers, Brookfield counter-rotating mixers, or homogenizing mixers may be used. Often, simple hand shaking is sufficient. Optional components and additional diluents may be added before, during or after the crosslinking reaction has taken place.

[0095] When using water and/or a polar organic solvent as the diluent it is preferred to carry out the reaction as an emulsion polymerization. Emulsion polymerization is well known in the art however, it typically entails simultaneous polymerization and emulsification wherein the resulting silicone elastomer composition is in the form of an emulsion, preferably a microemulsion.

[0096] Typically, the diluent is not removed from the silicone elastomer composition. However, it is possible to remove the diluent using techniques known in the art, for example, spray drying to produce a solid-like particle. The silicone elastomer may then be used in the solid-like form or it may be re-swelled in the same or a different diluent.

[0097] One of the benefits derived from silicone elastomer compositions prepared according to this invention is their structural integrity against changes in such parameters as temperature, and the presence or absence of other components such as water, surfactants, and oils. Another benefit is their reduced permeability for entrapped active ingredients by the formation of crosslinked structures.

[0098] The silicone elastomer compositions are useful in personal care products, for example, in preparing antiperspirants and deodorants. They can be used in skin creams, skin care lotions, moisturizers, facial treatments such as acne or wrinkle removers, personal and facial cleansers, bath oils, perfumes, colognes, sachets, sunscreens, pre-shave and after-shave lotions, shaving soaps, and shaving lathers. They can be used in hair shampoos, hair conditioners, hair sprays, mousses, permanents, depilatories, and cuticle coats. In cosmetics they can be added to make-ups, color cosmetics, foundations, blushes, lipsticks, eyeliners, mascara, oil removers, color cosmetic removers, and powders. In such applications the compositions may include oil soluble, polar solvent soluble, and water-soluble ingredients such as vitamins as noted above.

[0099] These compositions are also capable of functioning as carriers for pharmaceuticals, biocides, herbicides, pesticides, and other biologically active substances; and they have utility as additives for cellulosic or synthetic nonwoven carrier substrates used in wet-like cleansing wipes such as wet-wipes, tissues, and towels, marketed generally for personal hygiene and household cleaning tasks.
