Description

Detergent paste.

  The present invention relates to a detergent paste

  intended mainly for hand washing.

  The sector of the technology considered is that of cleaning products and, in particular those intended for laundry

  manual, as well as detergent and soap compositions.

  We know that the traditional soap, if it meets the current concerns "ecological", has many disadvantages, especially when used in limestone water. In contrast, we nowadays propose the most effective synthetic detergents as for the cleaning properties. They are particularly criticized for their high cost, because of the increase in the petroleum products from which the synthetic components used, the resulting pollution, especially by the use of polyphosphates as "builders" and complexing substances.

hard.

  The problem to be solved is therefore to avoid as much as possible the use of expensive synthetic products, eutrophysants while eliminating the inconvenience of precipitation encountered with the

traditional soap.

  The invention proposes a new detergent paste for manual washing and its objective is to start from natural raw materials, palm and coconut fatty acids, which, products of recovery during the refining of these edible oils, are therefore not a cost too high and to add a soda / potash mixture and a biodegradable dispersing agent, according to the following composition: - between 16 and 20% of palm fatty acids between 3.5 and 5.5 Z of fatty acids coconut - between 3 and 8% of n-methyl sulfonated fatty acid esters, expressed by weight of components relative to the total weight of said composition and the necessary quantities of sodium hydroxide and potassium hydroxide in solution for the saponification of said fatty acids, the soda / potash ratio

  being approximately 2/1 (by weight).

  Preferably, the detergent paste composition further comprises: between 1.5 and 3% (by weight) of sodium silicate, between 3.5 and 5.5% (by weight) of sodium hypochlorite, about 0. , 4% (by weight) of enzyme, - between 1 and 1.5% (by weight) of perfume,

between 50 and 60% by weight of water.

  A particular detergent paste composition is as follows: AG Palme 1 AG Coprah Soda (solution) 50% Potash (solution) 50% Sodium silicate Esters of c-methyl sulfonic acid Sodium hlypochlorite Fragrance Colorant C Water 5 (8, 1% (in 4.5% (in, 8% (in 2, 5% (in 1.7% (in terms of weight weight weight weight reported reported reported reported relative to weight to weight to weight to total weight) total) total) total), OZ (by weight relative to the total weight) 4.5% (by weight relative to the total weight) L, 3% / (by weight relative to the total weight) 0, 017% (by weight It is also advantageous to use as fatty acids the by-products of the refining of palm and coconut oils for food use, which are, in particular, available in the form of a total weight of 6,18% (by weight relative to the total weight). in various

  developing countries collecting these oils in large quantities.

  One of the applications of the invention is the profitability of such byproducts in soapmaking, the final product being a paste particularly intended for manual washing still widely used, and in particular in the same oil-producing countries.

already mentioned.

  The product obtained is a product consisting of a detergent paste for manual washing whose main advantage is to be based on natural materials, biodegradable and not polluting the surrounding environment while having excellent performance

for laundry.

  Another advantage is its increased foaming power by

  the use of coconut fatty acids.

  The α-methylsulfone fatty acid esters confer a

  dispersing power to the dough while meeting the above conditions

  previously cited biodegradability and non-pollution, silicate

  increases the detergency of the dough and the additives

  improve the cleaning properties and appearance.

  Another advantage is its relatively cheap cost of

  recover by-products from the refining of cooking oils

  and the minimal use of expensive synthetic products.

  Another advantage is the possibility of disposing on the spot the production of the products according to the invention made from primary raw materials (fatty acids) of the country, renewable, and to avoid the importation of expensive synthetic materials.

  (surfactants derived from petroleum and tripolyphosphates for example).

  Other features and benefits will be better

  understood on reading the description of the invention which will follow

  Embodiments: The detergent paste, the final product according to the invention, is in the form of a "soft soap", intermediate between the hard soap, produced by the saponification of fatty acids with sodium hydroxide. and "liquid soap", product of saponification of acids

fat by potash.

  Essentially, the essential components of the dough are palm and coconut fatty acids, soda and potash,

  in solution, and α-methylsulfonated fatty acid esters.

  The mixture of palm and coconut fatty acids is important in that an addition of about 20% by weight of coconut fatty acids, based on the total weight of fatty acids, gives a better foaming power to the coconut oil. dough. This is a quality

  very sought after, especially in hard water.

  The pasty degree of the final product is determined by the

  soda / potash ratio, roughly evaluated to at least 2 to 1.

  The quantity of soda and potash is calculated according to that

of fatty acids to be saponified.

  In order to disperse "lime soaps", characterized by gray deposits on the linen, the containers in which the washing is done, when the water used contains "hard" ions, a preferential agent taken from the sodium esters is used. u-methylsulfonated fatty acids having the formula: R - C10 COOR 'SO (3Me Me being a metal, for example alkaline;

  R and R 'being preferred linear chain alkyl radicals;

  These products respond to the need for biodegradability in the surrounding environment. The amount of water entering the composition

  is at least half by weight of all components.

  In addition, in order to improve the detergent properties of the paste, it is also possible, in very limited proportions, to use alkaline adjuvants which play the role of "builder", such as sodium silicate, which also protects against corrosion. the containers. We can also add sodium hypochlorite, enzymes to catalyze the degradation of stubborn stains (colloidal, egg, blood, for example, fruit juice, perfumes such as: synthetic bergamot,

  hydroxycitronnellol, methyl dihydrojasminate, phenyl alcohol

  ethyl, synthetic jasmine, vettiveryl acetate ...

  It is also possible to color this paste by adding the product chosen in quantities varying according to their nature and well known to those skilled in the art, but in any case always minute, reported.

  Preferably, the raw materials used are natural. Fatty acids are sub-products derived from the physical refining of palm and coptab oils for food use.

  It is also possible to use fatty acids which are the distillation products of the same oils. However, in this embodiment, the unit price and the loading price of the kilo of raw material is higher. As an indication, these are given below for the fatty acids concerned in this preparation: Examples of composition are given below for the
