Abstract
Disclosed herein are chemical car wash cleaners. They contain ethylene oxide/propylene oxide block copolymers, anionic surfactants, and water. They clean vehicles without requiring hand drying of the vehicle to avoid spotting and without adversely affecting beading properties.
Description
CAR WASH CLEANER
BACKGROUND OF THE INVENTION
to 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 i5 do not adversely affect beading properties after the car has dried.
There have been various efforts to automate the washing of cars and other vehicles. While soaping and rinsing steps have been satisfactorily automated, attempts to automate the 2o drying step have proved difficult and/or energy inefficient.
If left to dry on their own, vehicles washed with conventional car wash cleaners would typically be left with spots on their exterior finish. Hand drying is labor-intensive (and thus costly) and blow drying is energy 2s inefficient and noisy.
Various dishwashing detergents are known that minimize spotting on glassware and the like. For example, BASF sells a number of polymers under the marks "Pluronic~" and "Tetronic~" that improve rinsing performance on glassware 3o when mixed with dishwashing detergent. Moreover, in U.S.
patent 5,770,548 there is a disclosure of using cleaning compositions containing surfactants, silicate and hydrophobic acrylic polymer to clean window glass and other hard surfaces without the need for hand drying.
However, the designer of a vehicle cleaner must take into account additional considerations beyond simply anti-spotting capability. For example, such a cleaner must be compatible with standard waxes and finishes typically found on vehicles. A rinse 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 j ob) .
Thus, a need exists for improved car wash cleaners and methods of cleaning vehicles using them.
BRIEF SUMMARY OF THE INVENTION
In one aspect the invention provides a composition for cleaning a vehicle containing a copolymer of ethylene oxide and propylene oxide, anionic surfactant and water. In one form, the copolymer is selected from the group consisting of ~Hs HO-(CH2CH20)X-'(CH2CH0)y-(CH2CH20)X~ H
where each of x, y, and x' is 2-300, and I H3 I Hs HO-(CHCH20)X (CH2CH20)y-(CH2CH0)X~ H
where each of x, y, and x' is 2-300.
In another aspect, the copolymer can be selected from the group consisting of:
_2-~Hs ~Ha H-(OCH2CH2)y~~ (OCHCHz)X~~ ~(CHZCHO)X-(CHzCH20)y-H
/N-CHz-CHz-N~
H-(OCH2CH2)y~~~ (O~HCH2)X~~~ (CH2~H0)x~ (CHZCH20)y~ H
where each of x, x', x", x "', y, y', y", and y "' is 2-500, and ~Hs ~H3 H-(OCHCH2)y~~ (OCH2CH2)x~~ ~(CH2CH20)X-(CH2CH0)y-H
/N-CH2-CH2-N~
H-(O~HCH2)y~~~ (OCHZCH2)X~~~ ~. (CH2CH20)x~ (CH2~H0)y~ H
where 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).
In preferred forms these 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.
In yet another form 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°.
The most preferred surfactants are alkali metal sulfate or sulfonate surfactants such as sodium dodecylbenzene sulfonate (SDS) and sodium laureth sulfate ISLES). In one form they are sold as BIO SOFT D40 and Steal CS-230 from Stepan Chemical Co. They are preferably employed with the SDS in a major amount of about 30% to about 35% by weight and the SLES in a minor amount of about 3% to about 5% by weight. Other 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. In addition, other types of surfactants may be used in minor amounts.
A preservative (e. g. formaldehyde) is preferably also present. Other 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. For use in a sprayer 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. In such a method, the cleaners can be applied by hand (e. g. via a rag, pad or sponge) and subsequently rinsed off with a hose. Alternatively, 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:
(a) which can be rinsed off and air dried without leaving readily visible spots;
(b) which do not adversely affect a waxed surface;
(c) which are relatively inexpensive to produce;
(d) which are suitable for use with water of varying hardness;
(e) which can be diluted to low concentrations and still be effective; and (f) which use environmentally acceptable components.
These and still other objects and advantages of the present invention (e. g. methods for using said cleaners) will be apparent from the description which follows. The following examples are merely the preferred embodiments.
Thus, the claims should be looked to in order to understand the full scope of the invention.
