Abstract

Described are liquid to pasty washing and cleaning agents containing anionic or anionic and non-ionic surfactants in quantities from 20 to 70 % by wt., and including as anionic surfactants 2 to 25 % by wt. of sulphonated fatty-acid glycerin esters. Such washing and cleaning agents suffer no loss in washing performance compared with liquid to pasty washing- and cleaning-agent formulations usually containing surfactants.

[Detailed description of the invention] liquid or paste detergent The present invention is based entirely or at least in large part on oleochemical systems, i.e. renewable Concerning liquid or paste detergents containing anionic surfactants made from raw materials. Ru.

Obtained from renewable vegetable and/or animal raw materials, with excellent ecological compatibility The importance of using oleochemical surfactant compounds characterized by constantly increasing. For example, as an oleochemical compound with good ecological compatibility. is a vegetable alcohol with 10 to 20 carbon atoms in its raw fatty alcohol molecule. and/or sulfation of fatty alcohols of animal origin, neutralized and water-soluble. known fatty alcohols obtained by preparing the corresponding alkali metal salts, especially the corresponding alkali metal salts. with 10 to 20 carbon atoms in the fatty acid molecule α-sulfonation of methyl esters of fatty acids of vegetable and/or animal origin After that, neutralization and water-soluble monosalts, especially the corresponding alkali metal salts and hydrolysed Known α-sulfo fatty acid alkyl esters obtained by forming their di-salts (ester sulfonate).

Examples of other oleochemical surfactant compounds include sulfonated fatty acid glycerol, Stell, for example, as described in International Patent Application Publication No. 91/6532. Sulfonated unsaturated fatty acid glycerin ester or International Patent Application Publication No. 91/90 It is a sulfonated product of saturated fatty acid glycerin ester described in No. 09.

Economically, the most important anionic surfactants today are still alkylbenzene sulfurs. Belongs to the phonate surfactant group. The disadvantage of alkylbenzene sulfonates is that It is obtained from oleochemical raw materials.

Therefore, the problem to be solved by the present invention is that the problem to be solved by the present invention is Contains anionic surfactants made from natural or renewable oleochemical raw materials The object of the present invention is to provide a liquid or paste detergent that can be used as a detergent. These anion interfaces Detergents with active agents do not reduce cleaning power and other formulations are standard Totally or at least partially with alkylbenzene sulfonate in the formulation can be replaced with

Therefore, the present invention provides that the surfactant content in the detergent is 20 to 70% by weight. , the detergent contains 2 sulfonated fatty acid glycerin esters as anionic surfactants. Anionic surfactants or anionic and non-ionic surfactants containing from 25% to 25% by weight. This invention relates to a liquid or paste detergent containing a surfactant.

Fatty acid glycerin ester is a monoglycerin ester with 1 to 3 moles of fatty acid. Esterification or esterification of triglycerides with 0.3 to 2 mol of glycerin Mono-, di- and triester obtained when produced by transtelling reaction and mixtures thereof. Fats and oils, i.e. different fatty acids If a natural mixture of glycerin esters is used as a starting material, Their fatty acid composition typically consists of a portion of saturated fatty acids and a portion of unsaturated fatty acids. will be accomplished. Suitable sulfonated fatty acid glycerin esters include, for example, mustard oil, sunflower oil, cottonseed oil, olive oil, peanut oil, linseed oil, fish oil, Unsaturated fatty acid glycerin obtained on the basis of rapeseed oil rich in oleic acid or oleic acid. Examples include sulfonated products of esters. Said International Patent Application Publication No. 91/6 Sulfonation may be carried out according to No. 532.

However, preferred sulfonated fatty acid glycerin esters are 6 to 22 is a sulfonation product of saturated fatty acids having 4 carbon atoms, e.g. acids, caprylic acid, capric acid, myristic acid, lauric acid, valmitic acid, stenoic acid Mention may be made of sulfonated products of arilic acid or behenic acid. If fats and oils, In other words, starting material is a natural mixture of different fatty acid glycerin esters. If used again, the starting material is hydrogenated by known methods before sulfonation. to saturate the majority, i.e. bring them to an iodine value of less than 5, on average less than 2; Hydrogenation is necessary in this case. Typical examples of suitable starting materials include These include palm oil, palm kernel oil, palm stearin, olive oil, rapeseed oil, and coli. mustard oil, sunflower oil, cottonseed oil, peanut oil, linseed oil, lard oil or lard can be mentioned. However, due to the high natural content of saturated fatty acids, the starting material It has proven particularly advantageous to use coconut oil, palm kernel oil or tallow as I know. As described in the said International Patent Application Publication No. 91/9009, Saturated fatty acids of 6 to 22 carbon atoms or 6 to 22 carbon atoms A mixture of fatty acid glycerin esters with an iodine value of 5 or less having a fatty acid of Sulfonation by reaction with gaseous sulfur dioxide can be followed by neutralization with an aqueous base. preferable.

The sulfonation product is a mono-, It is a complex mixture containing di- and triglyceride sulfonates. sulfone fatty acid salts, glyceride sulfate, glycerin sulfate, glycerin and soap are formed as by-products.

Su in the mixture Aluminum containing 10 to 80% by weight of sulfonated fatty acid glycerin ester Contains a mixture of cansulfonate and sulfonated fatty acid glycerin ester The detergent is equivalent in cleaning power to a mixture containing only alkanesulfonates. This is what we know at this point. The formula does not reduce cleaning power, Alkanesulfonates are completely replaced by sulfonated fatty acid glycerol esters. It is even possible to change it.
