Description

[Detailed Description of the Invention] Background of the Invention The use of soap as a cleaning agent dates back to the dawn of civilization.
It has had a long history of safety and effectiveness.

When used as a cleaning agent, soap has two important drawbacks: its insufficient solubility in cold water and the insolubility of calcium and magnesium salts in water. In a push to eliminate these drawbacks, the cleaning industry has turned away from soaps and has adopted various synthetic surfactants as active ingredients in its cleaning compositions.

It is well known that in hard water, insoluble scum is produced that tends to clump together, forming what is called lime scum or lime soap.

This tends to deposit on the washed fabric or on the surfaces of the containers in which washing and rinsing takes place.

For fabrics, dirt from normal washing is generally about 4ON.
It consists of 50% of fine dirt and 60% of oily dirt from human sebum or sweat. The particulate soil component as washing soil consists primarily of about 75% clay and silica and about 20% lime soap. Lime soaps are generally not adequately removed by surfactants in cleaning compositions or are sequestered by sodium tripolyphosphate or other similar materials that may also be present in cleaning compositions. Eventually, lime soap will be deposited on the washed fabric.

This condition leads to a gradual "greying" of the washed fabric,
This leads to an unpleasant odor on fabrics caused by the enzymatic corrosion of the unsaturated fatty acids in lime soap.

Lime scum deposits on the containers and forms what is known as "pastor bling" in the containers when cleaning and rinsing is performed.

Over 30 years ago it was discovered that lime soap precipitation could be prevented through the addition of lime soap dispersants to the soap. However, these formulations can be harmful to the environment due to a phenomenon called eutrophication, or simply due to excessive seaweed growth in the water into which the phosphate-containing used cleaning solution is discharged. Contains sodium birophosphate, which is approved.

Lime soap or lime scum is approximately 0.01 to 0 in size.
．． 03crn, an essentially insoluble calcium salt of fatty acids in the form of large aggregates of 100-300μ.

Such aggregates are not effectively dispersed by surfactants commonly used in cleaning formulations. When a lime soap dispersant is present in a cleaning composition, it breaks down or disperses large lime soap aggregates down to micron or submicron particles to provide a milky white dispersion. Thus, the presence of the lime soap dispersion in the cleaning composition allows the lime soap to be flushed or rinsed away, so that the build-up of lime scum on the fabric is reduced or eliminated, and the formation of greasy tap rings is prevented. can do.

Therefore, lime soap dispersants act to prevent the formation of insoluble lime soaps or the agglomeration of such soaps, so that they can be flushed away in washing or rinsing water, and can be removed from fabrics or containers to be washed. Do not allow it to adhere to surfaces.

U.S. Pat. No. 3,692,704 discloses a cleaning composition comprising about 50% by weight detergent and about 50% by weight detergent builder, the builder component having an Mwl 0000
60% by weight of sodium polyacrylate with 0 and M
40% by weight of poly(N,N-dicarboxymethylacrylamide) with w50000.

US Pat. No. 3,719,647 discloses copolymers of (meth)acrylic acid and polyalkylene glycol mono(meth)acrylates as whitening agents in cleaning compositions. They are said to be effective lime soap dispersants.

SUMMARY OF THE INVENTION In a preferred embodiment, the present invention provides a water-soluble homopolymer of polyalkylene glycol monoacrylate. Acrylamide alkanesulfonic acid as a novel polymer and as a polymer that can be used as a lime soap dispersant in detergents and soap compositions. Random copolymers with realkylene glycol monoacrylates and methods of cleaning fabrics and hard surfaces and using such compositions in personal cleaning stations. Such compositions may be phosphate-free or phosphate-containing.

Anionic surfactants and soaps do not play an effective role in hard water media.

However, the lime soap dispersants disclosed herein in combination therewith lead to improved cleaning and foaming effects in such conditions. For other common types of surfactants, their cleaning effectiveness in water is adversely affected by the presence of water hardener ions such as calcium and magnesium. The hardness of natural water ranges from about 10 ppm to about 500 ppm expressed as calcium carbonate.
The hardness of the substance varies widely up to pm. Salts that impart hardness to water are generally water-soluble salts of calcium and magnesium such as chlorides, sulfates, nitrates and bicarbonates. Generally, 10-120 ppm is considered to be soft water, 120-180 ppm is semi-hard water,
180-500 ppm and above is truly hard water. In normal use of soaps and cleaning products, undesirable lime soap scum begins to form even in 80 ppm or soft water and is not a significant problem in semi-hard water.
In really hard water this becomes a major problem.

Lime soap dispersants are used in soap and detergent products, but each serve very different purposes. In soap products, such as solid bars and liquids, lime soap dispersants increase lathering and when such soap compositions are used in relatively hard water, bathtubs and basins. to prevent the formation of unwelcome rings of calcium or lime soap. In cleaning compositions such as powders and liquids, lime soap dispersants are used to wash away lime soap deposits on washed fabrics that are not removed by other cleaning ingredients. . Removal of such lime soap deposits on washed fabrics preserves the white color of white fabrics for longer.
This will prevent unpleasant fatty odors.

The cleaning compositions of the invention can be in the form of liquid melts, powders, granules, flakes, tablets and bars. However, regardless of the form, a small amount of the detergent composition is required in an aqueous medium to obtain a good cleaning powder. Generally less than 1% by weight, preferably between 0.01% and 0.5% by weight of the total mold of cleaning composition and water will provide a sufficient amount of cleaning agent for fabric and dish cleaning. Good morning. For cleaning fabrics and dishes, up to 30%, preferably 5 to 15%, of the detergent composition in an aqueous medium can be used for more severe applications. For personal cleaning, the amount of cleaning composition can vary from about 1% to about 10% by weight of the composition and water. The aqueous solution of the cleaning composition disclosed herein has a molecular weight of 5 to 12.5, preferably 9 to 11

many homopolymers and cores]? Limers were prepared with varying compositions and molecular weights which were then subjected to total lime scum dispersion and lime dispersion tests to determine their effectiveness. This test follows general methods described in published literature. The purpose of this test is to determine the minimum amount of lime soap dispersant required to completely disperse a given amount of calcium oleate lime soap.

This conclusion is expressed as the lime soap dispersibility index (LSDI) as shown in the following 5. The higher the LSDI, the better the budding of the lime soap dispersant. In general, L.S.D.
I is a measurement of the thunder of lime soap dispersed by a unit weight of lime soap dispersant.

The lime soap dispersibility test used herein uses the following reagents: (a) Sodium hydroxide or acid resistant, with pH adjusted at 105 °C in deionized water at 1.0 °C. .509- USP Sodium Oleate L

The test method is carried out at room temperature at 25° C. by placing 5 ml of sodium oleate solution 7 (1°) into a graduated cylinder with a stopper of 1QQml! at room temperature of 25°C. Add 10 ml of hardness solution into the cylinder and add enough deionized water to make the total volume 30 dt. Stopper the cylinder and then gently invert it. , return it to its original vertical position and repeat this 20 times. Allow at least 1 minute to pass, then watch the contents carefully. If coarse calcium oleate aggregates have solidified on top, , if it floats, you know that the lime soap dispersant is stuck and does not need to be used fully.

The test repeats the above method using a new cylinder;
and continued by increasing the volume of LSD polymer solution to Q, 5 ml. The method is Q, 5
Repeat with increments of mA of LSD polymer. As the amount of LSD polymer increases, the coarse calcium oleate aggregates will break up into small particles that remain floating on the surface.

The end point is reached when there are no longer any calcium oleate particles visible floating on the bath surface and the entire test solution appears opalescent, which is indicative of the overall dispersion.
