The invention relates to opaque, liquid cleaning agents, particularly for personal use determined and free from soaps of fatty acids.

High-quality bar soaps have been preferred for personal hygiene for years. You are mild to it the skin and form an abundance of thick, dense foam. However, they inherently have the disadvantage on that they react with hard water to form lime soap, which turns out to be an ugly deposit attaches to washing vessels and bathtubs and leaves a dull film on the hair. Furthermore, soap is often wasted if the soap basin and bowl are insufficiently drained through the formation of ugly smears from softened soap. The latter disadvantage can be avoided by using a dispenser that is a clear liquid soap, usually Contains potassium or sodium-potassium coconut or oleate soap. However, it is difficult to deal with the usual soap solutions to form a dense, thick foam, as can be achieved with bar soaps.

The problem of soap lime deposits can be solved by using a synthetic detergent can be solved in bar form or liquid form, but this creates new problems. Synthetic Detergents do not foam on the skin in the same way as soaps. The foam is not as dense and thick and less slippery. This is especially noticeable when the synthetic detergent on a washcloth in the bath under the shower or in the bathtub is needed. Under these conditions it is difficult to produce a dense, soap-like foam to achieve.

Synthetic detergents do not leave the same thing on the skin of a certain group of people Feeling like soaps. After using detergents, the skin may feel dull and dry feel. For example, if the hands are rubbed against each other after washing, they will slide Palms not smoothly on top of each other, as is the case when ordinary soap is used. Rather, they stick to each other, creating an uncomfortable feeling. The properties of the For most people, however, the foam and the feel on the skin are the benchmarks for the quality of a product Soap.

The liquid soaps for personal use on the market are usually clear Solutions and often contain a little dye that is added to make the soaps look more attractive. The opaque, creamy appearance of hand lotions and liquid detergents

Cold creams are considered by many consumers as a characteristic of mildness and luxury items. The main problems In making an opaque, creamy product consist of diluting too much with a To avoid inert opacifiers and to achieve a stable dispersion of the opaque agent.

The invention relates to a soap-free detergent that at least acts on the skin is just as mild as soap, which behaves like a toilet soap, but no lime soap deposits in hard water forms an opaque, iridescent shape without the use of a diluent has pourable lotion and a smooth, slippery, but not oily feel on the skin leaves behind.

The aforementioned properties of the washing lotion are obtained with a mixture that contains the Contains the following essential active ingredients in the amounts specified below:

1. A mixture of alkyl glyceryl ether sulfonate salts,

2. a long-chain tertiary amine oxide,

3. an additional anion-active, sulfated or sulfonated detergent salt and

4. a water-soluble polymer of the type specified below.

The essential active ingredients, inorganic salts and other desired ingredients are dissolved or suspended in an aqueous vehicle.

The type and concentration of the individual components are explained in more detail below. the Concentrations are given in percent by weight. Unless otherwise stated, the Percentages based on finished cleaning agents. It should be noted that in the case of an aqueous solution

is not possible to specify which cations should escape with 16 to 18 carbon atoms in the alkyl radical Anions are associated, because all of them persist, thus due to their insolubility in the finished product Parts are loosened during manufacture, so that a cleaning agent replaces the opaque, iridescent, lotion of ions taking place among them. The like appearance is obtained. The alkyl groups of both Overall composition can thus be based on different 5 fractions can have the same carbon number or can be digested Way, using different grain sizes, have different C-numbers. When that cleansing binaries the same cations and anions can be achieved by diluting them with water for use. becomes the opacifying agent at least in part

The sole metal cation can be dissolved in the cleaning agent and contributes to the formation of foam.

Potassium causes an increase in the viscosity of the typical is the following composition: 2% C ₁₀ , product, which increases the stability of the dispersion of 66% C ₁₂ , 23% C ₁₄ and 9% C ₁₆ . A suitable opacifier is increased. The potassium can be the starting material for a _{mixture consisting predominantly of C 16} and wholly or partly of low molecular weight alkanol C ₁₈ alcohols are hydrogenated amines, such as ethanolamine, diethanolamine and tri-tallow fatty alcohols.

* The following additional washing active Sub-3 ° are used punch: A sodium salt of the sulfated condensation product of nonylphenol with 4 moles of ethylene oxide; B sodium salt of sulfated condensation product of 1 Md of the mean cut of coconut oil fatty alcohol with 3 moles of ethylene oxide and C Sodium alkyl sulfate in which the alkyl radicals come from the middle cut of coconut oil fatty alcohol. 35

The products had the same good appearance as the products according to Example 1. In terms of effectiveness and properties, the products A and C were practically equivalent to those of Example 1, while product B with Alkyläthylenoxydsulfat as an additional detergent substance in relation to the Appearance was equivalent and was satisfactory in terms of effectiveness and properties. Sodium N-methyl-N-taurate of coconut oil fatty acid or the coconut fatty acid of sodium isethionate can be used as an additional detergent substance, without significantly impairing the appearance, effectiveness and properties of the product.

With these ingredients an opaque, iridescent liquid product with a pleasing appearance is obtained obtain. It forms a thick, dense foam and leaves the skin feeling smooth. It is suitable excellent for personal hygiene.

Instead of the above-mentioned acrylamide polymer, it can be used without deteriorating the appearance and the effectiveness and properties of the cleaning agent acrylamide polymers are used, the a) 40 mole percent acrylic acid residues, b) 10 mole percent methacrylic acid residues, or c) 10 mole percent Contain sodium salt of methacrylic acid residues and otherwise have the same composition.

ίο All six products are stable, pourable Liquids with a pleasing, opaque, iridescent appearance.

When used to wash the hands, a thick, pliable foam was obtained which was at least equivalent to the foam formed by bar soap. After the hands were dry, they felt pleasantly smooth and not dull and dry.
Due to its liquid form, the product is suitable for automatic dispensers and for all kinds of deformable plastic containers that can be squeezed together to dispense the product. The product is also very suitable for use from a pressurized pack and can be removed as a liquid or as a foam. Fluorinated and chlorinated hydrocarbons of the type commonly used for such purposes can be used as pressure generating agents.
