Definitions

• the present invention relates to vehicle cleaners which do not require hand drying. More particularly, it relates to car wash cleaners which permit rinse water to readily sheet off the vehicle during the rinsing process, yet which do not adversely affect beading properties after the car has dried .
• a rinae aid which improves sheeting during the car wash process, but also destroys the ability of car wax to cause beading is a commercially unacceptable additive (as consumers would believe that the cleaner had destroyed the wax job) .
• the invention provides a composition for cleaning a vehicle containing a copolymer of ethylene oxide and propylene oxide, anionic surfactant and water.
• the copolymer is selected from the group consisting of:
• the copolymer can be selected from the group consisting of: CH 3 CH 3 H-(OCH 2 CH 2 )y"-(OCHCH 2 ) x - ⁇ ⁇ CHzCHO ⁇ — (CH 2 CH 2 0) y — H — CH 2 -CH 2 -N
• each of x, x' , x " , x "' , y, y' , y " , and y '" is 2-500.
• Overall molecular weights of the copolymers are preferably between 1,000 and 50,000, with total EO and total PO units each preferably under 150 (even more preferably each under 50) .
• compositions contain at least 50% water, between 0.5% and 8% block copolymer, and 20% to 45% anionic surfactant.
• the preferred anionic surfactants are sulfates, sulfonates, and mixtures thereof, especially sodium dodecylbenzene sulfonate, sodium laureth sulfate and mixtures thereof .
• the compositions can also contain a preservative such as formaldehyde, and other ingredients such as dyes, fragrances, other rinse aids, and fillers.
• the composition can be applied in concentrated form to deal with particularly soiled areas, diluted with water in a bucket and directly applied with a sponge or the like, or diluted with water and sprayed onto a vehicle.
• the invention provides methods for cleaning the surface of a vehicle by applying the above compositions to the vehicle, followed by rinsing with water.
• the vehicle can then air dry (either from a stationary position, or while moving) .
• a variety of the copolymers within the block copolymer formulae of claim 2 are sold by BASF under the trade designation Pluronics * .
• a variety of the copolymers within the "block" copolymer formulae of claim 10 are sold by BASF under the trade designation Tetronics ⁇ .
• anionic surfactants can be used such as sodium alkyl aryl ethoxy sulfates, sodium lauryl sulfate, sodium linear alkylate sulfonates, disodium sulfosuccinate , and diammonium lauryl sulfosuccinate .
• other types of surfactants may be used in minor amounts.
• a preservative e.g. formaldehyde
• preservatives include anti-microbials such as Kathon (Rohm & Haas) , Dowicil (Dow Chemical) , and Canguard (Angus Chemical) .
• Water is preferably 50% to 70% of a concentrated form of the composition.
• the compositions can be diluted with water (e.g. one part of the concentrated composition diluted with 60-175 parts of water, or even more) . As noted above with respect to the spot use of the concentrated formula, no such dilution is required. However, absent such dilution the cost of washing an entire vehicle using the concentrate could be quite expensive.
• the cleaners of the present invention can be used to wash vehicles such as automobiles, vans and trucks from a bucket.
• the cleaners can be applied by hand (e.g. via a rag, pad or sponge) and subsequently rinsed off with a hose.
• the cleaner can be sprayed onto the vehicles in more diluted form using an automated sprayer, and then rinsed off using an automated rinsing system. In either case, the vehicles dry by evaporation.
• the objects of the present invention therefore include providing cleaners of the above kind:
• EXAMPLE 1 EXAMPLE 2 Ingredient % wt . % wt .
• the present invention provides chemicals that are particularly useful for cleaning vehicle exteriors, and methods of using these cleaners.
