Abstract
Surfactant systems and compositions incorporating the same are disclosed for use as rinse aids on plastics and other wares. The surfactant systems and compositions include both liquid and solid formulations, along with methods of use for treating plastics and other wares. The surfactant systems and compositions provide synergistic combinations allowing lower actives in composition formulations of the plastic-compatible surfactant systems providing good sheeting, wetting and drying properties.
Claims21
1-20. (canceled)
21:
- A method of rinsing a surface comprising:
- applying a rinse aid composition to a surface in need of rinsing;
- wherein the rinse aid composition comprises a surfactant system comprising:
- (i) at least two surfactants according to the following formulas:
- wherein R1 is a straight-chain C10-C16 alkyl, wherein x3 is from 5 to 8, and
- wherein y3 is from 2 to 5,
- wherein R1 is a straight-chain C10-C16 alkyl, wherein x4 is from 4 to 6, and
- wherein y4 is from 3 to 5,
- wherein R2 is a C10-C14 alkyl with an average of at least 2 branches per residue, and
- wherein x1 is from 5 to 10,
- wherein R7 is a branched C8-C16 Guerbet alcohol, x5 is from 5 to 30, y5 is from 1 to 4, and y6 is from 10 to 20,
- wherein x is from 88 to 108, y is from 57 to 77, and z is from 88 to 108, and
- wherein x is from 15 to 25, y is from 10 to 25, and z is from 15 to 25;
- and
- (ii) optionally an additional surfactant according to the following formulas:
- wherein R2 is a C10-C14 alkyl with an average of at least 2 branches per residue, and
- wherein x2 is from 2 to 4,
- wherein R6 is a C8-C16 Guerbet alcohol, wherein x4 is from 2 to 10, and wherein y4 is from 1 to 2, and
- wherein x is from 12 to 20, y is from 120 to 220, and z is from 12 to 20.
16 more elements
22:
- The method of claim 21, wherein the rinse aid composition further comprises an additional functional ingredient.
23:
- The method of claim 23, wherein the additional functional ingredient is an additional functional ingredient is a solidification aid, carrier, chelating agent, bleaching agent, sanitizer, defoaming agent, anti-redeposition agent, optical brightener, dye, odorant, stabilizing agent, dispersant, enzyme, corrosion inhibitor, thickener, solubility modifier, or a combination thereof.
24:
- The method of claim 21, wherein the surfactant system comprises surfactant (A) or surfactant (A2), and surfactant (B), and optionally surfactant (C).
25:
- The method of claim 21, wherein the surfactant system comprises surfactant (A), surfactant (B), and surfactant (D), or wherein the surfactant system comprises surfactant (A2), surfactant (B), and surfactant (D).
26:
- The method of claim 21, wherein the surfactant system comprises surfactant (H) or surfactant (D), and surfactant (G), and optionally surfactant (A).
27:
- The method of claim 21, wherein the surfactant system comprises surfactant (B) and surfactant (D), and optionally surfactant (F).
28:
- The method of claim 21, wherein the surfactant system comprises surfactant (A) or surfactant (A2), and surfactant (D) or surfactant (H).
29:
- The method of claim 21, wherein the rinse aid composition is a liquid concentrate or a solid.
30:
- The method of claim 29, wherein the rinse aid composition is a pressed solid or an extruded solid.
31:
- The method of claim 21, further comprising a first step of contacting the rinse aid composition with water to dilute the rinse aid composition.
32:
- The method of claim 31, wherein the rinse aid composition diluted with water has an actives concentration of less than 5 wt. %.
33:
- The method of claim 31, wherein the rinse aid composition diluted with water has about 1 ppm to about 125 ppm of the surfactant system.
34:
- The method of claim 21, further comprising a step of reducing the contact angle of the surfactant system composition by at least about 5° compared to the contact angle of a commercially-available rinse aid composition to induce sheeting and result in a faster drying time of the surface.
35:
- The method of claim 21, wherein the method is used in a warewashing application.
36:
- The method of claim 35, wherein the warewashing application includes one or more rinse cycles in a commercial warewashing machine.
37:
- The method of claim 35, wherein the one or more rinse cycles include a hot water sanitizing rinse cycle, a chemical sanitizing rinse cycle, or a combination thereof.
38:
- The method of claim 35, wherein the warewashing application is a low temperature warewash application, wherein the method is performed at a temperature of 140° F. or less.
39:
- The method of claim 21, wherein the surface is cookware, dishware, flatware, glasses, cups, hard surfaces, glass surfaces, plastic surfaces, or a combination thereof.
40:
- The method of claim 21, wherein the method reduces spotting and filming on the surface.
