Definitions
- the present invention relates to a novel family of compositions based on alkyl glycosides and alcoholic esters of amino acids, peptides or proteins.
- Another aspect of the invention relates to an advantageous mode of preparation of these compositions.
- compositions as surface-active agents, in particular in the fields of detergency, agrochemistry and cosmetics.
- Alkyl glycosides or polyglycosides are well known nonionic surfactant compounds (J.A.C.S. 60, 2076, 1938; US 6156543; US 5688930). They can be used alone or in combination with other surfactants in a wide range of industrial applications. The properties sought by users depend essentially on the application sectors.
- alkyl glycosides are used as surfactants in the formulation of detergents, cosmetics or agrochemical formulations.
- Detergent is an important sector of use of alkyl glycosides. This use is motivated inter alia by the search for a high surfactant power, by the generation of large foam volumes, by the search for solubilization properties of non-water-soluble compounds and by a favorable ecotoxicity and biodegradability.
- Alkyl glycosides are especially used as an emulsifier in the manufacture of emulsions, mini-emulsions or microemulsions with an aqueous or oily continuous phase (US 6087403, US 6596779, WO 2005110588, WO 2005121294).
- Emulsions are known and widely used in industry either as materials to be consumed or to be applied to surfaces as non-water soluble agents.
- emulsions in cosmetics (milks, creams, ointments), in cooking (sauces, creams), in galenics (ointments, creams), in paint (paint without odor), in the road industry (bitumen in emulsion), in agrochemicals (phytosanitary products), detergents, rolling mills, steelmaking and the manufacture of various deposits (printing, adhesives, etc.).
- emulsions are an effective way to obtain the harmonious combination of ingredients of different nature and properties in a homogeneous and easy-to-use presentation.
- Many phytosanitary compounds are insoluble in water and, being previously solubilized in an organic solvent, they can be emulsified in water at the time of application or formulation by a suitable choice of glycoside-type emulsifiers. alkyl.
- the good foaming power of alkyl glycosides is a tare in the cleaning of surfaces by auto-washer, high-pressure lance or in the "washing in place" operations of the food industry, washing bottles or automatic washing of dishes.
- foam volumes interfere with washing and rinsing and decrease the efficiency of operations.
- the formulator will have to add to the detergent based on alkyl polyglycosides a compound with non-foaming properties or "anti-foams" to reduce the phenomenon.
- the anti-foam agents generally used are of petrochemical origin and expensive. They also have an unacceptable environmental profile. There is therefore a need for new compositions based on alkyl glycosides whose foaming capacity can be controlled.
- the alkyl glycosides sometimes exhibit instability at dilution which results in a loss of the effectiveness of the detergents, in particular with regard to the surfactant activity. There is therefore still a need for new compositions based on stable alkyl glycosides whose efficiency makes it possible to lower the surface tension at low concentrations.
- alkyl glycosides do not always make it possible to formulate emulsions that are sufficiently stable over time (WO 92/06778, WO 95/13863, WO / 9822207). These emulsions are also known to not tolerate the presence of electrolytes.
- the formulator to overcome this defect, will combine its emulsifying system with additives such as polymers or complexing agents that are expensive and difficult to implement. There is therefore also a need for compositions based on alkyl glycosides whose emulsifying power is improved, especially in the presence of electrolyte.
- alkyl glycosides can be improved by association with alcoholic esters of amino acids, peptides or proteins.
- the present invention also relates to an advantageous mode of obtaining these compositions.
- the invention relates to the uses of these compositions as surfactants for the preparation of detergents, cosmetics or agrochemical formulations.

- the second aspect of the invention is a process for the advantageous preparation of the compositions according to the invention.
- compositions are predominantly composed of alkyl pentosides but comprise only a very small amount of compounds of amino acid esters, peptides or proteins type.
- Patents EP 0699472 (which we will call Dl document), and Patent WO 9729115 (which we will call D2 document) in the name of the applicant, describe processes for the preparation of glycoside surfactants which consist in bringing wheat bran into contact with a wheat. acidic aqueous solution and / or an enzymatic complex. Thus, a pentose juice is obtained which must be removed from the marc (lignocellulosic residue).
- the juice freed from its marc must then be concentrated (distillation of water) before being used in glycosylation of an alcohol having from 6 to 22 carbon atoms, which makes it possible to obtain a mixture of pentosides.
- the pentosides are obtained from the pentoses by a first glycosylation reaction with butanol and then by transglycosylation with a fatty alcohol.

- the mechanism is very different from D1 and D2 because it is a direct transglycosylation of pentosans in pentosides in fatty alcohol.
- the process does not pass through "Pentoses juice”. It then becomes unnecessary to purify and concentrate the pentoses since they are directly converted into glycoside surfactants.
- the reaction is carried out without butanol solvent as is the case in Dl and D2.
- the method according to the present invention is therefore easier to implement since it comprises a single unit operation and moreover, makes it possible to obtain better yields.

- Annual plant means any plant with a vegetative life of the order of one year (such as cereals and various grasses such as maize, sorghum, barley and wheat, hemp, hn, cane sugar %) and perennial plant, plants whose development extends over a longer period (such as bamboo, hardwoods, softwoods ).
- Ligno-cellulosic plant materials are whole plants or parts of the said plants (stems, bark, %) or co-products of industrial production chain for food purpose (wheat straw, rice, barley, bagasse cane sugar, bagasse sorghum sugar ).
- the process according to the invention has the advantage of obtaining in a single unit operation effective surfactant compositions unlike the processes described in the Dl and D2 patents on behalf of the applicant, which require the execution of several operations of hydrolysis and consumption concentration of water and complex glycosylation, especially in the case of the use of higher fatty alcohols.
