## Title
Hydrolysis resistant organomodified disiloxane ionic surfactants

## Abstract

An asymmetric organomodified disiloxane surfactant having the formula: MM′ wherein M comprises branched hydrocarbon substituents and M′ comprises a cationic, anionic or zwitterionic substituent and a polyether substituent that may be combined as one moiety, wherein the disiloxane surfactant has an enhanced resistance to hydrolysis between a pH of about 3 to about 12.

## Background
FIELD OF THE INVENTION
The present invention relates to disiloxane surfactant compositions that exhibit resistance to hydrolysis over a wide pH range. More particularly the present invention relates to such hydrolysis resistant disiloxane surfactants having a resistance to hydrolysis between a pH of about 3 to a pH of about 12.
BACKGROUND OF THE INVENTION
The topical application of liquid compositions to the surfaces of both animate and inanimate objects to effect a desired change involve the processes of controlling wetting, spreading, foaming, detergency, and the like. When used in aqueous solutions to improve the delivery of active ingredients to the surface being treated, trisiloxane type compounds have been found to be useful in enabling the control of these processes to achieve the desired effect. However, the trisiloxane compounds may only be used in a narrow pH range, ranging from a slightly acidic pH of 6 to a very mildly basic pH of 7.5. Outside this narrow pH range, the trisiloxane compounds are not stable to hydrolysis undergoing a rapid decomposition.

MMH 

where MH is the hydride precursor to the M′ structural unit in the composition of the present invention, wherein the definitions and relationships are later defined and consistent with those defined above, under hydrosilylation conditions, with an olefinically modified epoxy-containing moiety, such as allyl glycidyl ether or vinyl cyclohexene oxide, which are incorporated here as examples, and not set forth to limit other possible olefinically modified epoxy components, followed by subsequent reaction with an amine-containing group.

Epoxy-modified organofunctional disiloxanes are straightforwardly prepared through the use of a hydrosilylation reaction to graft the olefinically modified (i.e. vinyl, allyl or methallyl) epoxy group onto the hydride (SiH) intermediate of the organomodified disiloxane of the present invention.
Precious metal catalysts suitable for making epoxy-substituted siloxanes are also well known in the art and comprise complexes of rhodium, ruthenium, palladium, osmium, iridium, and/or platinum.

The platinum compound can be selected from those having the formula (PtCl2Olefin) and H(PtCl3Olefin) as described in U.S. Pat. No. 3,159,601, hereby incorporated by reference. A further platinum containing material can be a complex of chloroplatinic acid with up to 2 moles per gram of platinum of a member selected from the class consisting of alcohols, ethers, aldehydes and mixtures thereof as described in U.S. Pat. No. 3,220,972 hereby incorporated by reference. Yet another group of platinum containing materials useful in this present invention is described in U.S. Pat. Nos. 3,715,334; 3,775,452 and 3,814,730 (Karstedt). Additional background concerning the art may be found in J. L. Spier, “Homogeneous Catalysis of Hydrosilation by Transition Metals”, in Advances in Organometallic Chemistry, volume 17, pages 407 through 447, F. G. A. Stone and R. West editors, published by Academic Press (New York, 1979). Those skilled in the art can easily determine an effective amount of platinum catalyst. Generally an effective amount ranges from about 0.1 to 50 parts per million of the total organomodified disiloxane composition.

Additionally comparative trisiloxane alkoxylates were prepared by conventional methods of platinum mediated hydrosilation, as described in Bailey, U.S. Pat. No. 3,299,112, herein incorporated by reference.
Comparative sample A is a trisiloxane ethoxylated surfactant containing 8.5 polyoxyethylene repeat units. This product is commercially available as Silwet® L-77 from Momentive Performance Materials, Wilton, Conn.
Additionally, comparative sample OPE (Octylphenolethoxylate, containing 10 polyoxyethylene units) is a non-silicone organic surfactant. This product is available as Triton® X-100 from Dow Chemical Company, Midland, Mich.
Example 1
This example demonstrates the ability of the organomodified disiloxane surfactant compositions of the present invention to reduce aqueous surface tension, thereby showing utility as surfactants. Surface tension was measured using pendant drop analysis. Solutions of the various components were prepared at 0.1 wt % in water (deionized) or 2M NH4Cl solution.
Table 1 shows that solutions of these unique compositions provide a significant reduction in surface tension relative to the conventional surfactant.
The compositions of the present invention also provide spreading properties similar to the comparative trisiloxane surfactant A. Additionally, organomodified disiloxane surfactants of the present invention provide improved spreading relative to the conventional organic surfactant product OPE.
Spreading was determined by applying a 10 μL droplet, of surfactant solution to polystyrene Petri dishes (Fisher Scientific) and measuring the spread diameter (mm) after 30 seconds, at a relative humidity between 50 and 70% (at 22 to 25° C.). The solution was applied with an automatic pipette to provide droplets of reproducible volume. Deionized water that was further purified with a Millipore filtration system was used to prepare the surfactant solutions.

Example 2
Unlike traditional siloxane based surfactants, which are subject to rapid hydrolysis under acidic and basic conditions (≦15 and ≧pH 9), the organomodified silylated surfactants of the present invention provide increased resistance to hydrolysis relative to traditional trisiloxane alkoxylates (Comparative Example A). An artifact of hydrolysis is observed as a reduction in spreading properties over time. Therefore, solutions of the organomodified silylated surfactants of the present invention, as well as comparative surfactants, were prepared at desired use levels and pH. Spreading was determined as a function of time to illustrate resistance to hydrolysis.
Table 2 is an illustrative example of a traditional organomodified trisiloxane ethoxylate surfactant, which exhibits decreased spreading performance with time as a function of hydrolytic decomposition over a pH range from pH 3 to pH 10. Here a 0.4 wt % solution of sample A was prepared at pH 3, 4, 5 and 10. Spreading was determined by applying a 10 μL droplet of surfactant solution to polyacetate film (USI, “Crystal Clear Write on Film”) and measuring the spread diameter (mm) after 30 seconds, at a relative humidity between 50 and 70% (at 22 to 25° C.). The solution was applied with an automatic pipette to provide droplets of reproducible volume. Deionized water that was further purified with a Millipore filtration system was used to prepare the surfactant solutions.

As mentioned above, resistance to hydrolysis was observed by monitoring the spreading properties over time. Here a 0.1 wt % solution of surfactant was prepared in distilled water containing 10 wt. % NaCl at pH 4, 5, 9 and 11. Spreading was determined by applying a 10 μl droplet, of surfactant solution to polystyrene Petri dishes (Fisher Scientific) and measuring the spread diameter (mm) after 30 seconds, at a relative humidity between 50 and 70% (at 22 to 25° C.).

The appended claims are intended to claim the invention as broadly as it has been conceived and the examples herein presented are illustrative of selected embodiments from a manifold of all possible embodiments. Accordingly it is Applicants' intention that the appended claims are not to be limited by the choice of examples utilized to illustrate features of the present invention. As used in the claims, the word “comprises” and its grammatical variants logically also subtend and include phrases of varying and differing extent such as for example, but not limited thereto, “consisting essentially of” and “consisting of.” Where necessary, ranges have been supplied; those ranges are inclusive of all sub-ranges there between. Such ranges may be viewed as a Markush group or groups consisting of differing pairwise numerical limitations which group or groups is or are fully defined by its lower and upper bounds, increasing in a regular fashion numerically from lower bounds to upper bounds. It is to be expected that variations in these ranges will suggest themselves to a practitioner having ordinary skill in the art and where not already dedicated to the public, those variations should where possible be construed to be covered by the appended claims. It is also anticipated that advances in science and technology will make equivalents and substitutions possible that are not now contemplated by reason of the imprecision of language and these variations should also be construed where possible to be covered by the appended claims.
