These mixtures show greatly reduced gel formation and rapid redissolution of any gel that may be formed in addition to excellent foam, detergency, degradability and viscosity properties.

For the production of the detergent mixtures according to the invention, an olefin monosulfonate is particularly suitable, which is the sulfonation product of an olefin mixture with about 75 to 85% straight-chain <^ -olefins (olefins of the formula R-CH = CH ₂ , in which R is an aliphatic hydrocarbon group), about • 8 or 10 to 20% olefins in which the olefinic bond is in a vinylidene group (e.g. olefins

409843/1008

of the formula R-CC = CH ₃ ) -R ', in which R and R ^{1 are} aliphatic hydrocarbon groups with preferably at least 4 carbon atoms) and about 5 to 12% internal olefins (for example olefins of the formula R-CH = CH-R ', in which R and R' are aliphatic hydrocarbon groups). Such olefin mixtures are preferably prepared by polymerizing ethylene with a Ziegler catalyst to form a mixture of O ^ rolefins of different chain lengths, a fraction of essentially C ₁₄ - to then

The sulfonation of the olefins can be carried out with sulfur dioxide at a low partial pressure (for example at a partial pressure below about 100 mm Hg and preferably below about 25 mm Hg). The SO _{3 can be} in gaseous form, undiluted, i.e. in a vacuum or together with an inert one

409843/1008

Diluents (e.g. air). If appropriate, however, it can also be in liquid form (for example in solution in SO ₂ at a low temperature such as, for example, 0 ^° C.). The molar ratio of SO ₃ to olefin is usually about 1: 1 to 1.2: 1 and is preferably less than 1.12: 1, for example about 1.05 to 1.1: 1. The reaction product resulting from the sulfonation can then be mixed with a 10 to 15 mol percent excess of an aqueous alkali in order to neutralize the sulfonic acids. By heating, a hydrolysis of the sultones present as the main part of the reaction product, which is formed by ring opening, can be carried out. The resulting product usually contains about 40 to 80 wt.% And preferably about 50 to 70 wt.% Alkenyl sulfates, about 15 to 70 and preferably 20 to 40 wt 7 to 15% so-called impurities such as sodium sulfate, free oil and sodium chloride.

The amine oxides and alkylol amides generally improve foam properties by increasing the volume and / or improving the foam stability in the presence of greasy dirt, while at the same time gel formation is reduced. On the other hand, the lower aliphatic organic monosulfonates reduce the gel formation properties of aqueous liquids containing olefin sulfonates and alkanolamides or Amine oxides as show improvers and, optionally, ethoxylated Alkyl sulfates as additional surfactants.

Suitable tertiary amine oxides as foam improvers correspond to the general formula R ₁ R ₃ R ₃ N—> 0, in which R _{1 is} an alkyl,

The Älkanolamide g are as suds in general, together with the detergent-active compounds, namely the mixture of olefin sulfonate and ethoxylated alkyl sulfonates used, wherein the ethoxylated Alkylsuifonat in liquid detergents with a. Content of C _g to C ^ "- and preferably C ₁₂ to Cj ^ -Alkansäurediäthanolamiden can be omitted if the weight ratio of olefin sulfonates to alkanolamide is about 3½ to 1½ and preferably about 3½ to 1.5: 1. In such mixtures, the olefin sulfonate salt is usually used in amounts of about 5 to 40% by weight and preferably about 10 to 35% by weight of the total _{liquid detergent and the C ß} to Cg-alkanoic acid diethanolamide in amounts of about 3 to 15 and preferably 7, 5 to 10% by weight of the total mixture is used, which results in improved foam stability or an increased foam volume.

4098A3 / 1008

about 4% by weight, since this amount is sufficient to reduce the tendency of such mixtures to form gel-like skins and to improve the redissolution of any gel-like shapes formed. This shows a significant advantage compared to the mixtures of the prior art, in which the gel formation leads to clogging of nozzles or spouts the container can lead. Liquid detergents without ethoxylated alkyl sulfates have anti-gelling properties obtained when the weight ratio of olefin sulfonates to antioxidants is about 16: 1 to 2: 1, mostly etv / a 7: 1 to 3: 1, and preferably about 4: 1.

Collages or the like can be obtained. During hydrolysis the proteins are slowly converted into the Jexveiligen polypeptides *, and Amino acids broken down by prolonged heating with acids such as sulfuric acid, or alkalis such as for example sodium hydroxide or by treatment with enzymes such as peptidases. Form during hydrolysis first high molecular weight polypeptides, which as - - hydrolysis slowly broken down into simpler and smaller polypeptides down to tripeptides, mpeptides and finally amino acids will. It follows from this that polypeptides from proteins represent a complex mixture, their mean molecular weight can vary between about 120 (amino acids) to about 20 * 000. All polypeptides that are sufficiently hydrolyzed are distinguished by their water solubility. When using mixtures with • soluble proteins, those are preferably used which hydrolyzed collagen with such a low molecular weight contain that they are completely soluble in water, non-gelling and non-denatured, the average molecular weight less than 15,000, preferably about 500 to 10,000 and, for best results, about 1,00O: is *:.: -,

In soft water, water hardness salts such as magnesium sulfate or calcium chloride are added in amounts of about 0.5 to 4% by weight will. Alkali citrates, gluconates or aminopolycarboxylates can be used to sequester metal ions such as iron ions in the wash water Be added in amounts of 0.1 to 1% by weight. Other additives such as optical brighteners, dyes, Emollients, perfumes, bactericides or similar compounds can be used in amounts up to about 2% by weight for improvement certain properties are added.

In addition, the liquid detergents according to the invention can, under certain circumstances, contain small amounts of other surfactants, if these do not impair the excellent properties of the detergents. Such surfactants are mostly added in amounts of substantially less than 10% and preferably less than 5% of the total surfactant content of the mixture. Suitable Surfactants can be, for example, anionic, nonionic, amphoteric, zwitterionic or polar nonionic surfactants, because they have good washing properties and net and foam properties as well as other favorable properties.

The mixtures of Examples 8 to 10 were tested for their tendency to gel and their ability to redissolve that formed Gels examined as follows:

Approximately 100 ml of each liquid detergent of Examples 8-10 was placed in a bottle which was then sealed and placed in a constant temperature bath of -3.9 ° C. After three days the bottles were removed and visually check the amount of gel formed.

409843/1008

seeks. The bottles were then left at room temperature. put down and checked how long it took to dissolve of the formed gel was required.

Gel formation leads to clogging of the spouts or nozzles of the dispensing containers in which the liquid is packaged.

It was also examined how many plates were left with the detergent when using the "Miniature Dishwashing Evaluation Method" (Journal of the American Oil Chemists Society, Volume 43, No. 10, pages 576-580) could be washed. In this process, two watch glasses of different sizes, each with a weighed amount of greasy dirt (so-called mini-plates) in a solution of the examining person Washed detergent, the foaming power of the solution as a measure of the number of mini-plates washed before exhaustion foaming is indicated.

Here, too, it is shown again that mixtures with a high proportion of lauric acid-myristic acid-diethanolamide surprisingly have greatly improved washing properties in contrast to the teaching of, for example, US Pat. No. 3,332,878, which stated that diethanolamides give "poor results". It is also found that small amounts of monoethanolamides Can be added to the detergents, provided that the monoethanolamides do not exceed 25% by weight and preferably not more than 20% by weight, for example 15% of the total content of alkanolamides as foam improvers .

The mixtures of Examples 29 and 30 were used as follows to determine the effect of the anti-gelling agent and the effect examined for gel formation: 1 ml of the liquid mixture was run down a glass plate, and although open to the atmosphere, with the plate held at an angle of 30 to the horizontal. Then became the distance covered by the mixture measured and the flow properties (straight or wavy) observed.

A wavy flow motion indicates that gel formation is occurring, while with a straight flow motion none or "one" only slight gel formation has occurred. The distance covered is thus a measure of the tendency towards gel formation. The results, which indicate the relative tendency towards gel formation, are compiled in Table D below:
