The present disclosure is directed to compositions and methods for use in automotive care. In particular, the present disclosure is directed to water-based compositions comprising a silicone emulsion that are particularly beneficial as a gloss booster, enhancer, and/or sealant.
Gloss-enhancing products currently on the market for automotive surfaces offer to enhance gloss. However, there are various drawbacks and issues with these products. Moreover, one must use multiple products to deliver hydrophobicity, durability, and gloss properties.
There remains a need, therefore, to provide an automotive surface gloss composition—in one product—that is capable to deliver hydrophobicity, durability, and gloss properties to the surface.
In one aspect, the present disclosure is directed to a composition comprising: a non-ionic amino functional silicone emulsion and a preservative.
In another aspect, the present disclosure is directed to method of treating an automotive surface, the method comprising: applying a composition to the automotive surface, wherein the composition comprises: a non-ionic amino functional silicone emulsion and a preservative.
Described herein is water-based automotive care composition that is particularly beneficial as a gloss booster, enhancer, and/or sealant. It is particularly beneficial for hard, exterior automotive surfaces (e.g. paint, trim, wheels, tires, glass, mirrors, etc.).
In addition to acting as a gloss booster, enhancer, and/or sealant, the composition according to the present disclosure boosts color depth and revitalizes the look of automotive surfaces. It can be applied on top of waxes, sealants, and coatings. It can also be applied in-between car washes. The composition is configured to impart hydrophobicity (water repellency) and durability to the surface.
In many embodiments, the composition protects surfaces by implementing hydrophobic polymers to repel water and aqueous solutions.
In some embodiments, the composition comprises a non-ionic amino functional silicone emulsion and a preservative. In some embodiments, the composition is used as part of a method to treat an automotive surface by applying the composition to the automotive surface.
In some embodiments of the present disclosure, the non-ionic amino functional silicone emulsion contributes to the hydrophobicity and durability of the composition. In some embodiments, the non-ionic amino functional silicone emulsion comprises an aminoalkyl-functional organopolysiloxane fluid and water. In some embodiments, the non-ionic amino functional silicone emulsion comprises a non-ionic emulsifier. In some embodiments, the non-ionic amino functional silicone emulsion comprises water. In some embodiments, the aminoalkyl-functional organopolysiloxane fluid is selected from the group consisting of an amine-alkyl/dimethyl copolymer, a polar amine/alkyl functional block, an amine/alkoxy end-blocked silicone, and combinations thereof.

Without further elaboration, it is believed that one skilled in the art using the preceding description can utilize the present invention 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.
A sample composition in accordance with the present disclosure is shown in Table 1. The composition has a clear and transparent to slightly cloud appearance. It has a pH of 5.57 and a water-thin viscosity.
A sample composition in accordance with the present disclosure is shown in Table 2.
A sample composition in accordance with the present disclosure is shown in Table 3.
A sample composition in accordance with the present disclosure is shown in Table 4. The composition has a clear and transparent to clear appearance and an orange odor. It has a pH of between 5 and 6 and a water-thin viscosity.
Citric acid is added last and is added piecewise. The pH of the composition should be checked before and after adding the citric acid to make sure the pH of the solution is between 5 and 6.
A sample composition in accordance with the present disclosure is shown in Table 6. The composition has a clear and transparent to slightly cloud appearance. It has a pH of about 6 and a water-thin viscosity.
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 invention. The term “consisting essentially of” occupies a middle ground between “comprising” and “consisting of”.
Where an invention 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 invention 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 invention 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.
