Description

LOW-VOC WATER-BASED CLEANER FOR PEN, INK, MARKERS, PAINT

FIELD OF THE INVENTION

Cleaning compositions to remove from surfaces such as desks, dry erase boards, spray equipment, and furniture deposits and stains such as dry erase marker, nail polish, correction fluid, fountain & bail-point pen, latex paint and wood stain and restore them as closely as possible to a clean condition,

BACKGROUND OF THE INVENTION

Porous surfaces, such as those of carpets, clothing, tablecloths, napkins, automobile seats, athletic shoes, and certain metal and metal composites, to name only few, and hard surfaces such as concrete, stucco, metal signs, tile, wallpaper, vinyls, and wood floors, often receive deleterious deposits and stains. Such deposits vary widely in their identity, for example paints, dry erase markers, permanent marker, latex paint, and wood stain. The term "deposit" includes all of the foregoing, including stains caused by liquids and solids.

The above recitation exemplifies a broad range of materials which need to be cleaned of a broad range of deposits and stains. In response to this need, an equally wide range of cleaning compositions already exists in the market.

Generally speaking, commercial compositions are limited both in the range of their effectiveness, and also as to how efficient they really are for their intended purpose. If one intends to remove a wide range of kinds of deposits, he is likely to find a nearly-equal number of formulations to buy for the purpose. In addition, some of the stains and deposits are usually only partially removed, and with risk to the material being cleaned. On the consumer market today, for example, there is no known composition which will remove wine from a white tablecloth. This product will.

Furthermore, many existing compositions are objectionable from an environmental standpoint. This composition is water-based, and is environmentally acceptable. It has two low-Volatile Organic Compound (VOC) forms and a zero-VOC form.

It is an object of this invention to provide a water-based

environmentally acceptable, biodegradable cleaning composition which can be used to remove a surprisingly wide range of types of deposits and stains. Any residue of these compositions which might remain on the surface, or in the substrate underlying it, will not adversely affect the user or the surface to which it was applied,

BRIEF DESCRIPTION OE THE INVENTION

A composition according to this invention which provides for a wide range of applications is water-based and comprises, in addition to water: TKPP; EDTA(Ethylene diamine tetro acetic acid) and/or phytic acid or a mixture of them; glycol ether DPNP or glycol ether EB and DB ; acetone and acetic acid. In this specification, the term glycol EB means ethylene glycol n-butyl ether, and the term EDTA means ethylene diamine tetra acetic acid. By selecting the appropriate components, a range of VOC numbers can be achieved, at, for example, 18,18% VOC, 9,09% VOC, and zero VOC,

This formulation represents a paradigm shift away from traditional cleaners. Ail cleaners in the market today clean specified substrates, e.g. tiie cleaner, bathroom cleaner, floor cleaner, carpet cleaner, pre-wash; this formulation attacks specific stain types, for ANY substrate. Cleaners in today's market are basically just soap and water. This VOC-compliant formulation works better than non-VOC-formulations in the market, remaining safe for the environment, safe for the individual, and safe for any surface.

DETAILED DESCRIPTION OF THE INVENTION

This product consists essentially of a member of each of the following groups of ingredients: a. De-ionized water

b. TKPP Aqueous 60%

c. EDTA Versene 100

d. Glycol Ether DPNP, or glycol ether EB and DB_S or just glycol ether EB e. Acetone

f. Acetic Acid

g. fragrance

The proportions of the member or members in each group in the ultimate product are determined by the VOC percentage targeted for the product.

This is a water-based product. Percentages specified herein are in weight percentage of the total composition. However, in mixing the formulations to make the product, it is best practice to dissolve certain of the ingredients in water before adding them into the total formulation. If all of the ingredients are added to the water at one time, occasionally a clear solution might not result. For this reason it is preferred practice to dissolve the TKPP in water before adding the other ingredients.

Similarly, EDTA versene 100 is best supplied not as a dry product, but in a diluted form, about 34% EDTA to about 86% water. This is readily available in sndustnai concentration.

The other ingredients are either already liquid or readily dissolved, so as to enter the solution or be miscibte with it. No special procedure is necessary as to them.

The preferred embodiment is the first zero VOC formulation, formula A. The other formulations allow flexibility of product during the decrease in acceptable levels of VOCs in household cleaning products.

The combination of components used herein appears to function synergistically, by mechanisms which are not fully understood at this time. What has become apparent is that the total composition functions to a degree of effectiveness much greater than already-known compositions useful for the intended purposes, and that elimination of any of the groups greatly reduces the effectiveness of the composition,

Formulations according to this invention are remarkably versatile and effective for a wide range of deposits and stains on a wide range of substrates. Any residues can readily be removed, so that a clean surface remains. Any surface or substrate can be laundered or rinsed off to remove any residue.

This invention is not to be limited by the embodiments described in the description, which are given by way of exampie and not limitation, but oniy in accordance with the scope of the appended claims,
