Described herein are compositions and methods that impart a hydrophobic finish to surfaces, such as, for example, automotive surfaces. The compositions comprise an amino functional silicone emulsion, an amphoteric surfactant, and, a non-ionic surfactant.
Conventional car washes that provide wax deposition also known as “Wash and Wax”, after washing the car surface do not provide a suitable hydrophobic finish. Current non-wax-based car washes that are available in the market that use SiO2 or functionalized silicone-based technology provide a hydrophobic finish to the car surface after washing (compared to wash and wax), but these products have low foaming properties and also provide poor foam when used with a foam cannon—a device used to provide high foaming while washing the car using air pressure.
Conventional car washes that incorporate wax for hydrophobic finishes are generally high foaming as they use anionic surfactants. Typically, anionic surfactants have higher foamability compared to non-ionic and cationic surfactants. But, anionic surfactants when used with typical non-wax-based hydrophobic agents, form complexes and this, in turn, fails to provide a hydrophobic finish. This is due to the fact that traditional non-wax-based hydrophobic agents are cationic in charge. Cationic being positive and anionic being negative, the charge is canceled, rendering the hydrophobic agent ineffective.
One example of a cationically-charged silicone-based hydrophobic agent that is being used in the present disclosure is an amino siloxane. Amino siloxanes have a positive charge, which when they come in contact with the surface of, for example, a car (paint, wheel, rubber, glass), bond with the negative charge present on the surface, leaving behind a coating of silicone, which is hydrophobic.
The present disclosure solves the issue of high foaming without the use of anionic surfactants by using a combination of an amphoteric and non-ionic surfactant, while providing a hydrophobic finish by using an amino siloxane.
In one aspect, the present disclosure is directed to a composition comprising: an amino functional silicone emulsion, an amphoteric surfactant, a first non-ionic surfactant, and, a second non-ionic surfactant.

Without further elaboration, it is believed that one skilled in the art using the preceding description can utilize the present disclosure to its fullest extent. The following Examples are, therefore, to be construed as merely illustrative, and not limiting of the disclosure in any way whatsoever.
The foaming profiles for formulations in accordance with the present disclosure (I1-I5) and a comparative formulation (C1) are shown in Table 4. Foaming profiles are labeled as not acceptable (−), good (+), or very good (++).
The foaming profiles for formulations I1-I5 and C1 are also shown in
This written description uses examples to illustrate the present disclosure, including the best mode, and also to enable any person skilled in the art to practice the disclosure, including making and using any compositions or systems and performing any incorporated methods. The patentable scope of the disclosure is defined by the claims, and may include other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they have elements that do not differ from the literal language of the claims, or if they include equivalent elements with insubstantial differences from the literal language of the claims.
As used herein, the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having,” “contains”, “containing,” “characterized by” or any other variation thereof, are intended to cover a non-exclusive inclusion, subject to any limitation explicitly indicated. For example, a composition, mixture, process or method that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such composition, mixture, process or method.
The transitional phrase “consisting of” excludes any element, step, or ingredient not specified. If in the claim, such would close the claim to the inclusion of materials other than those recited except for impurities ordinarily associated therewith. When the phrase “consisting of” appears in a clause of the body of a claim, rather than immediately following the preamble, it limits only the element set forth in that clause; other elements are not excluded from the claim as a whole.
The transitional phrase “consisting essentially of” is used to define a composition or method that includes materials, steps, features, components, or elements, in addition to those literally disclosed, provided that these additional materials, steps, features, components, or elements do not materially affect the basic and novel characteristic(s) of the claimed disclosure. The term “consisting essentially of” occupies a middle ground between “comprising” and “consisting of”.
Where a disclosure or a portion thereof is defined with an open-ended term such as “comprising,” it should be readily understood that (unless otherwise stated) the description should be interpreted to also describe such an disclosure using the terms “consisting essentially of” or “consisting of.”
Further, unless expressly stated to the contrary, “or” refers to an inclusive or and not to an exclusive or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).
Also, the indefinite articles “a” and “an” preceding an element or component of the disclosure are intended to be nonrestrictive regarding the number of instances (i.e. occurrences) of the element or component. Therefore “a” or “an” should be read to include one or at least one, and the singular word form of the element or component also includes the plural unless the number is obviously meant to be singular.
As used herein, the term “about” means plus or minus 10% of the value.
This application claims priority to U.S. Provisional Application Ser. No. 63/003,354, filed on Apr. 1, 2020, the content of which is hereby incorporated by reference in its entirety.
