Definitions
- the invention relates to the field of fine chemistry. More specifically, the invention relates to a process for manufacturing a non-greasy emollient.
- Emollients are widely used in cosmetics and pharmacy, to make dry skin supple and to improve its elasticity.
- the term emollient generally designates a set of perceptions transmitted by touch and by sight. Perceptions induced by touch evoke softness, elasticity and sliding power. Perceptions induced by sight evoke shine and mat.
- emollients offered by suppliers of cosmetic raw materials are considerable. These emollients are distinguished from each other by their chemical nature but also by the result of two quantities: Polliness on application and Pollollience residual. There are emollients with a protective effect, others with a superfatting effect, some give the impression of a dry effect, others finally act as astringents.
- esters with a more or less long, linear or branched carbon chain. These fatty acids are themselves combined in the form of esters, with alcohols with a more or less long carbon chain, linear or branched. These esters and their fatty acids are the basis of the emollience effect. It is generally considered that there are in this category of emollient two families of esters: those having a completely natural origin, and those having a synthetic origin, the synthesis involving the esterification of fatty acid by alcohol. . Synthetic esters are generally made from saturated fatty acids, which gives them great stability against oxidation, but removes them from any possibility of playing a role by integration in biosynthetic processes.
- the liquid consistency of the oils is a first advantage which goes in the direction of obtaining an emollient effect. It is necessary to add to the effect of the liquid consistency that of essential fatty acids like linoleic acid always present in vegetable oils at variable contents which are function of the botanical origin of the oleaginous species from which they come. As we have previously reported, the transformation of this linoleic acid into other unsaturated fatty acids via a biosynthetic process, results in an effect important moisturizer helping to keep the epidermis in a good state of emollience.
- the problem is therefore to provide a process for manufacturing emollients whose molecular weight of the main components is less than about 600, preferably less than about 500, more preferably less than about 450 Dalton, which makes it possible to obtain a preparation.
- emollient to feel non-greasy from vegetable oils and fatty substances in general the second objective consists in transforming vegetable oils or fatty substances in general and in purifying the transformation product in conditions such that all the integrity of their fatty acids and of their unsaponifiable matter is respected, so as to exploit all the properties of fatty substances without having the disadvantage of their fatty feel.
- the method of the invention comprises the following stages: a) the interesterification of the triglycerides of a fatty material, preferably of vegetable origin, with a primary alcohol, preferably of vegetable origin, in the presence of a catalyst; b) removing the catalyst; c) distilling off the residual alcohol, preferably in the presence of a bleaching agent, then removing the bleaching agent; d1) or the fngisation of the residue, preferably discolored so as to at least partially crystallize the residual glycerides; then elimination in particular by filtration of said residual crystallized glycerides; d2) or the hydrogenation of the preferably discolored residue.
- step d1) said residual glycerides are mono-, di- or triglycerides resulting from incomplete interesterification by said primary alcohol in step a). Their elimination makes it possible to obtain products which are completely liquid at the temperature of fngelization in particular at room temperature, preferably at a temperature of at least 15 ° C.
- step d2) the hydrogenation of the residue leads to products with a higher melting point which are solid at room temperature, and generally with a melting temperature of between 25 and 80 ° C. depending on the molecular weight of the products.
- fatty matter means a refined or crude vegetable oil or fat, optionally hydrogenated; a refined or crude marine oil, possibly hydrogenated; or a refined or raw animal fatty substance, optionally hydrogenated; or a refined or raw anhydrous milk fat, possibly hydrogenated.
- the alcohol used in the interesterification step can in particular be chosen from C- ⁇ -C-22 alkanols, C3-C22 alkenols or branched C 3 -C 22 alcohols.
- These branched alcohols are alcohols capable of carrying C 1 -C 8 alkyl substituents.
- those of C 4 -C 18 are preferably chosen, in particular those of C 6 -C 18 ; among the branched alcohols in C3-C22, preferably those chosen in C ⁇ -C22-
- the fatty acid esters obtained from the primary alcohols in C 1 -C-22, preferably in Ce to C- ⁇ 8 is called according to the present invention waxes-esters.
- wax-esters generally denotes esters of fatty acids and fatty alcohols that are solid at room temperature; by extension, this term is attributed to any fatty acid ester and solid or liquid fatty alcohol at room temperature obtained according to the present invention.
- this term is attributed to any fatty acid ester and solid or liquid fatty alcohol at room temperature obtained according to the present invention.
- the length of the saturated alcohol involved it is thus possible to obtain, from vegetable oils, wax-esters liquid at 20 ° C.
- step a from about 30% by weight to about 150% by weight of alcohol relative to the weight of the fat is used.
- the residual alcohol content is generally between approximately 20% by weight and approximately 35% by weight relative to the weight of the starting alcohol.
- the catalyst used to carry out the interesterification reaction is preferably an alkaline base, an alkali metal alcoholate, an alkali metal or a strong acid.
- the catalyst is chosen from sodium hydroxide, sodium methylate, sodium metal or toluene-4 sulfonic acid.
- the interesterification reaction is generally carried out with stirring for approximately 0.5 hour to approximately 10 hours, under an inert atmosphere, for example under a nitrogen atmosphere, and at a temperature at least equal to approximately 100 ° C. and at most equal to approximately 200 ° C.
- the removal of the catalyst in step b), when the latter is of the alkaline type, is carried out with an excess of about 500% relative to the stoichiometric amount of a strong acid such as sulfuric acid or hydrochloric acid in aqueous solution at least N and at most 5N, necessary for the neutralization of the alkaline catalyst by stirring at room temperature for at least about half an hour and at most about one hour.
- the catalyst neutralization operation is then followed by washes with water, with for each of said washes carried out with stirring at a temperature between approximately 80 ° C. and approximately 100 ° C., an amount of water at least equal to approximately 10% by weight and at most about 20% by weight relative to the weight of the product to be washed.
- the distillation of the residual alcohol in the product neutralized in step c) is carried out under an absolute pressure of the order of 10 to 100 Pascal, at a temperature at least equal to approximately 65 ° C. and at most equal to approximately 230 ° C, for a period generally at most equal to approximately 4 hours and preferably equal to approximately 2 hours.
- said distillation operation is carried out in the presence of an amount of bleaching agent such as in particular activated carbon, at least equal to approximately 0.1% by weight and at most equal to approximately 1% by weight of the weight of product to be distilled. After complete cooling, the bleaching agent is generally separated from the distillation residue by simple filtration.
- step d1 The refrigeration operation is carried out in step d1) by stirring the discolored distillate, at a temperature between approximately 10 ° C and approximately 14 ° C, for a period generally at least equal to approximately 1 hour and at most equal to about 4 hours, after which the frozen product is filtered.
- the refrigeration temperature could be reduced, but this would involve a risk that part of the waxes-esters according to the invention crystallize and then be eliminated with the residual crystallized glycerides.
- the product (residue) recovered after distillation of the residual alcohol is hydrogenated in a reactor under a hydrogen pressure of approximately 1 to approximately 20 bar, in the presence of a catalyst such than a catalyst based on nickel or on palladium, at a temperature at least equal to approximately 100 ° C. and at most at approximately 220 ° C., for a duration generally at least equal to approximately 2 hours and at most equal to approximately 8 hours.
