Description

Field of application of the invention

The invention relates to a detergent for hands, which is particularly suitable for cleaning heavily soiled with oil and grease residues hands without subsequent use of soap and water. It is suitable for motorists who have to eliminate an engine or other breakdown on the way.

Characteristic of the known technical solutions From the literature ("Mengen und Stroke", Part 1 KIuwer Deventer, Netherlands, 9th Printing Drs. L.P. Edel, page 113) are the following Detergents for Hand Detergents known: Methylcellulose, Alcohol, Glycerin, Lanolin, Menthol, Nipagin and Wassur. Detergents made with these raw materials have a share of at least 14% Methylcellulose, which is needed for cream stabilization. All figures in percent refer to, also in the following Mass concentration. Methylcellulose and glycerin in these detergents, even in liquid form as a lotion, leave one more or

less sticky residue on the skin. Subsequent cleaning with water is absolutely necessary.

In other cleaning products, which are especially designed for cleaning oil and grease soiled hands, are

larger amounts for the skin harmful solvents such. As o-dichlorobenzene, butylglycol ether or turpentine.

These detergents also contain substances such as fatty acids, which in turn have a specific Leave stickiness. Not only for toxicological reasons is a subsequent cleaning with soap and water

necessary. Without a subsequent cleaning of the hands with soap and water is z. B. the steering of a car because of

Stickiness of the hands not to answer for. Other detergents include aliphatic chlorohydrocarbons such as trichlorethylene, 1,2-dichloropropane or cyclic ones Hydrocarbons such as diethylbenzene or ethylbenzene. In part, such raw materials are no longer up-to-date or internationally

even banned, as they not only have a skin damaging effect, but are also generally damaging to health.

Known are so-called skin waters for cleaning the hands. They contain u.a. Glycerin, Boric Acid and Vaseline. Mostly

the total amount of such products is over 60 to 70%.

Known commercial hand care products also contain additives such. Alginates, 2-di-ethoxy-ethane! (Carbitol), Glycols, silicone compounds and ethyl alcohol. These care substances also leave a sticky layer, or they degrease the skin with simultaneous damage

the cornea.

All liquid products described so far for cleaning the hands, especially of dirt, at work

Engines caused by oils and greases can only be used in conjunction with a subsequent cleaning with soap and water, otherwise they either do not have a cleansing effect, without making the hands sticky, or after

Rubbing hands on a dry cloth will leave some dirt, which will only be removed with soap and water

can be.

According to .Kosmetik ", published by the VEB Fachbuchverlag Leipzig, are in the cleaning of the skin in principle

3 methods differentiated:

1. Clean with water or water based. cleaning preparations

2. Cleaning with oil or oil-based cleansing preparations

3. mechanical cleaning or cleaning with solids-based cleaning agents

Such solids are u. a. Wood flour, sand or similar substances in combination with surfactants and / or solvents for Oils and fats. Again, a subsequent cleaning with soap and water or synthetic organic compounds

necessary, which are due to ihros molecular structure suitable to reduce the surface or interfacial tension of liquids, especially of water.

In the case of cleansing lotions, stability problems very often occur, which necessitate shaking before use. In DE-OS 3543918 a washing solution u.a. described for the hands, the u.a. Ethanol, n-propanol and water. you

is characterized in that it is high molecular weight propoxylated cetyl alcohol, high molecular weight

Carboxyvinylpolymere and one or more acid neutralizing compounds. When using this detergent, however, an immediately subsequent washing of the hands with soap and water is necessary because even here remains a sticky layer.

The hand washing lotions, which are described in DE-OS 3534278, can not be used without subsequent washing hands with water as the sole cleaning agent.

In DD-PS 209733 a hand washing paste, in particular for the cleaning of heavily soiled areas of the skin, is described. This product contains according to the invention u. a. 1 to 15% of a comminuted, porous Adsorberpolymeren crushed in a mill with an inner surface area above 10OmVg and a particle size below 50μΜ and 50 to 89% liquid glycol, 10 to 30% fatty polyethylene glycol, etc. As adsorber polymers are those based on divinylbenzene, Styren, alkylstyrene or mixtures thereof used. Also, the skin wash pastes of this invention are adhered to a plurality of the above-mentioned. unwanted effects.

Object of the invention

The aim of the invention is to allow the cleaning of heavily contaminated soil without soap and water. Insbesondare should with oil and fat soiled hands, such as. B. when working on motor vehicles vorkommer, can be easily cleaned without leaving smooth or sticky residues on the skin.

Explanation of the essence of the invention

The invention has for its object to develop a detergent for hands, which meets the above requirements. The object is achieved by a mixture having a pH of 5.8 to 6.5 and the following composition:

15 to 25% polyethylene oxide having an average molecular weight of about 1000,

- 15Lis25% isopropanol,

10 to 20% ethanol,

1 to 3% 1,2-propylene glycol,

0.5 to 1.0% of an alkylphenyl polyglycol ether having an HLB value of 11 to 13,

1 to 3% triethanolamine,

1 to 3% of an aqueous copolymer latex of styrene, 1,3-butadiene, methacrylic acid and an esterification product of the Diels-Alder adducts of maleic acid and

- as rest to 100%, water.

The addition of a small amount of perfume or fragrance is possible. The addition of small amounts of other substances used in the cosmetic industry, such as preservatives, drug extracts, vitamin oils, algae extracts or Jtrope active ingredients, is possible. It should be noted, however, that the mixture does not leave a smooth or sticky residue after application to the hands.

By adding metal stearates, the cleaning agent according to the invention can be converted into a gel form in a known manner.

Although the use of ethanol, isopropanol, triethanolamine and 1,2-propylene glycol in cosmetic care products is not commonly used in known cleansers. The use of low molecular weight polyethylene oxide is not common but can not be said to be surprising.

However, it is surprising for the person skilled in the art that the detergency of the cleaning agent according to the invention is enormously increased by the content of said copolymer. Similar polymers are u. a. used in adhesives; Therefore, it was not to be expected that in addition to the cleaning effect would also be non-tackiness.

Ausführungsbelsplol

The following example illustrates the invention. All quantities are by weight.

In a stirred tank at about 18 ⁰ C operating temperature, the following raw materials were mixed:

189kg polyethylene oxide with a molecular weight of 1000,

295kg distillate,

171kg isopropanol,

180kg of ethanol,

16.2 kg of 1,2-propylene glycol,

7.2 kg of alkylpheryl polyglycol ether having an HLB value of 12.3,

23.4 kg of triethanolamine.

After a short mixing time, the pH was measured, which had a value of 9.6. After a maturation time of about 30 minutes, 18.9 kg, calculated on solids, of a copolymer latex were added, as described in Example 2 of DD-PS 115358. Its composition is as follows:

17Gew.-Tle. butadiene

18 parts by weight. styrene

50Gew.-Tle. methacrylic acid

15Gew.-Tle. Diels-Alder adduct of maleic acid 200Gew.-Tle. distilled water 4 parts by weight. Sodium lauryl sulfate 0.05GeW ₁ -TIe. Ethylenediaminetetraacetic acid 0.1 part by weight. tert. Dodecyl mercaptan 0.1 parts by weight. Kaliumporsulfat.

After a further 10 minutes of mixing, a pH of 6.2 was measured. Already 25g of this product showed an excellent cleaning effect on heavily soiled hands. Only be '·

stubborn soiling, such as from spent graphite oil, the treatment had to be repeated. In all experimental cases, however, a complete cleaning of the hands without a subsequent washing with water and soap was possible. After cleaning, the hands were not sticky and felt comfortable.

The addition of fragrances made it possible to give the product according to the invention a pleasant fragrance which

after evaporation or after drying or dry rubbing of the hands was still effective even after a long time.

For this purpose, known Duftif fragrances that are customary in Erfrischungspräpp.raten are preferably used for this purpose. The beneficial effect of the detergents made within the limits of the invention was almost complete

to estimate identically.

All mixtures could also be made into a gel form by the addition of metal stearates.
