Description

CYCLIC SILOXANES THAT RELEASE ACTIVE INGREDIENTS Cross reference to related requests Not applicable Declaration regarding federally founded investigation Not applicable FIELD OF THE INVENTION The present invention relates to cyclic siloxanes suitable for use in a variety of applications including formulations for personal care, household products, automotive, textiles and molding materials, wherein the cyclic siloxane has been chemically modified to release a active ingredient on hydrolysis. The present invention further relates to such molecules wherein the rate of release of active ingredient is sufficiently slow, so that products formulated with the modified cyclic siloxane exhibit desirable effects for long periods.

BACKGROUND OF THE INVENTION The sustained, slow release of an active ingredient is a highly desirable trait in many personal care products, textiles, automotive, plastics, laundry and home. A variety of media have been proposed and implemented to achieve this goal. Among these means are to dissolve or suspend fragrant compounds in personal care emulsions (US 5,525,588, US 5,525,555, US 5,490,982, US 5,372,806, EP 0334490, WO 0064497), encapsulation of a fragrant compound (US 5,500,223, US 5,324,444, US 5,185,155). US 5,176,903, US 5,130,171, US 6,325,859, US 6,309,715, US 6,325,274, US 6,213,409, US 6,200,949, US 5,142,792, US 5,867,755, US 5,049,182, US patent applications 20020187221, 20020009522 and 20010008635, EP 1 1 16515. , EP 1061 124, EP 1 133929, WO 0179303, WO 01731 88, WO 9815192, WO 02076514), dissolving a fragrant compound in a hydrophobic phase, such as a silicone (US 5,449,512, US 5,160,494, US 5,234,689, WO 0241709 ), incorporation of a fragrant compound in cross-linked polymer (US 6,435,423, US 5, 139,864, US 6,379,689, US 5,387,622, US 5,387.41 1, WO 03032749, WO 02065858, JP 1 1047581), incorporation of fragrant compounds in permeable laminates ( US 6,500,444; US 5,071, 704; US 5,008.1 15), incorporation of fragrant compounds into matrices that soften at body temperature (US 4,908,208; EP 1 178107, WO 0016643), incorporation of fragrant compounds in matrices that biodegrade (US 6, 121, 343) or are bioactivated (US 5,378,468), incorporation of fragrant compounds in speed controlling membranes (US 6,063,365 and US 4,445,641), derivatizing silanes with fragrant alcohols to form alkoxy silanes (US 4,524,018 and US 4,500,725) and derivatizing fragrances to form photosensitive molecules that release the fragrance upon exposure to light (WO 02083620; JP2002020783A). The derivation of active to give organic molecules (ie, that do not contain silicon) hydrolyzables has also been well documented in the literature. The union of silicon-containing molecules with active ingredients is of particular interest because many active ingredients are highly functional organics and suffer from incompatibility with the silicones found in consumer and personal care products, leading to syneresis and other phenomena. phase separation. The derivation of silanes with long chain alcoholic skin care actives to give alkoxytrimethylsilanes (US 5,847,179) and derivation of silanes with skin exfoliants of hydroxycarboxylic acid to form (triorganosilyl) alkoxycarboxylates (US 6, 143,309; US 6,228,380; US 6,267,977) have been described. The direct displacement of a group leaving alkoxy on a silicon atom by a fragrant alcohol was reported by Alien, et al. to give silicon esters or fragrant linear silicate esters (US 3,215,719 and US 3,271, 305). Several others also reported similar alkoxy displacement reaction to form linear fragrant siloxane polymers or copolymers (GB 2,041,964; GB 2,042,890; EP 273266). The reaction of an alcohol, aldehyde, ketone or lactone with a silyl hydride in the presence of a metal carboxylate salt and a reducing agent to form linear polymers and copolymers was also reported (WO 9628497). Other routes of fragrant silicones using silyl hydrides were described by Anderson, et al. (EP 878497; JP 1 0330382; US 6,262,287) and Perry, et al. (US 6,046,154, US 6,077,923, US 6,153,578, US 6,054,547, US 6,075,111, US 6,322,777, US 6,083,901). In these processes, hydrosilylation chemistry was employed to bind the active portion of the molecule to the silicone backbone.

DMF (C2H5) 3N Note that DMF is dimethylformamide. This reaction scheme can also be used to prepare the 3-methi-3- (3- (1-methylethylphenyl)) propanal derivative: The reaction of carbonyl-containing species, for example, esters, ketones and aldehydes, requires the establishment of the tautomeric keto enol equilibrium. Tautomerism is the chemical phenomenon of establishing a balance between two or more structurally distinct compounds. In almost all cases, the difference between a tautomeric form of the equilibrium compounds and the other is the isomeric placement of a hydrogen atom. A prevalent form of tautomerism is the tautomeric equilibrium established between a carbonyl compound (ie, one containing a carbonyl group) and having an alpha hydrogen atom for the carbonyl group, i.e., a a hydrogen: Form keto Form enol In general, the equilibrium constant favors the keto form and the equilibrium rests on the left. The degree of enolization is affected mainly by solvent, concentration and temperature. When a strong base is present, both the enol and keto forms can lose a hydrogen ion (a proton), forming an enolate anion: (") • Because both of these structures differ only in the placement of electrons, these are canonical forms of the same ion instead of tautomeric isomers.As oxygen is more electronegative than carbon, the predominant canonical form is one where the ionic charge is more localized in the oxygen atom Because the tautomeric equilibrium between enols and ketones or aldehydes is not normally a preparative reaction, equilibrium must occur because ketones and aldehydes often react through their forms of enol as they do instantaneously in the preparation of the compounds of the present invention.This tautomeric keto-enol equilibrium is also established for esters or organic acids, ie, in the above structures when R8 includes an oxygen binding to a group R appropriate, for example, OR ', the compound is an organic ester For a more detailed explanation of this chemical a, see J. March "Advanced Organic Chemistry", John Wiley & Sons, New York (1985), pp. 66-68 and 527-529 and references therein. Fragrant molecules, alcohols, ketones and aldehydes, can be reacted as the enol or alcohol tautomer to produce silicone or siloxanes that carry fragrant portions. The reaction involves reaction of the alcoholic or enolic form of the molecule with hydrogen, hydroxyl or halogen attached directly to a silicon atom to form the fragrant derivative. The reaction involves formation of the conjugate base related to the tautomeric form of enol or alcohol of the molecule: RnOH is dissociated to H + and RpO "(conjugate base), n = 1, 2 or 3 (thus R1 etc, as previously defined); where R "OH is a fragrant alcohol or the tautomeric form of enol of a fragrant ketone or aldehyde The aldehydes and ketones react with alcohol (s) R'OH to form hemiacetals (aldehyde derivatives) or hemicetals (ketone derivatives): RCH (O) + R'OH?

RC (OH) (R'O) R ", which has a conjugate base obtained in the same way by removing the hydroxyl hydrogen: RC (O") (R'O) R ". As used herein, Rn are fragrant portions, i.e., monovalent radicals, either as a neutrally charged monovalent radical (Rp or RnO) or as a charged monovalent radical, derived from the conjugated bases of fragrant molecules, for example, Rn + + O "2?

The siloxanes that light active ingredients of the present invention are prepared from an organohydrogensiloxane via conventional hydrosilylation using the olefinic silane carrying active as the alkenyl source, an example of this reaction is: y = 3-15 In this specific case, the siloxane species is actually a mixture of cyclic siloxanes with and ranging from 3-15. In this way, an organohydrogensiloxane having the formula III or IV: 111 IV where R10, R1 1, R12 and R13 are each independently selected from the group of monovalent C1-C24 hydrocarbon radicals. The quantity t is greater than or equal to 3, the quantity u is greater than or equal to 1, and the quantity s is greater than or equal to 0, with the proviso that u + s must be equal to or greater than 3. The organohydrogenosiloxane is reacted under hydrosilylation conditions to produce an active-releasing siloxane having the formula I or II: I II where the components and subscripts satisfy the definitions and previous requirements and RF has the formula (R1O) a (R2O) b (R3O) c (R4) d (R5) eSiRu with Ru a divalent hydrocarbon radical of C2-C0, where the subscripts and components are as previously defined. This siloxane undergoes a slow hydrolysis under most conditions of use, whereby the siloxane releases an active ingredient containing carbonyl or alcoholic upon hydrolysis. This imparts a desirable effect to many different useful compositions, such as cosmetics and home-made products. The hydrosilylation reaction is conventionally carried out in the presence of a hydrosilylation catalyst selected from the group of hydrosilylation catalysts of ruthenium, osmium, rhodium, iridium, palladium and platinum. Examples of such catalysts are those described in U.S. Patents 2,823,218; 3, 159.601; 3, 159,662; and 3,775,452. The compositions of the present invention further provide that the siloxane releasing active ingredient have one or more substituents R1, R2 or R3, wherein each substituent is independently selected,
