    • Process for the preparation of polyimides or of their polypeptide hydrolysates which are at least 80% biodegradable, by thermal polycondensation of at least one amino acid, optionally followed by hydrolysis, the thermal polycondensation step being carried out in the presence of at least one "acid catalyst" chosen from sulphuric, nitric, phosphorous, sulphurous, hydrofluoric, silicic and sulphonic acids, organic sulphonic acids containing less than 50 carbon atoms, amino acids bearing a non-carboxyl strong acid function, organic phosphonic acids, organic carboxylic acids having a pK.sub.a lower than or equal to 5, preferably lower than or equal to 3; precursors of these acids; salts of these acids and of an amino acid which is similar to or different from that or those used; salts of these acids and of a polyimide derived from the polycondensation of at least one amino acid which is similar to or different from that or those used; hydrochloric acid and its precursors salts of hydrochloric acid and of an amino acid which is similar to or different from that or those used, when the amino acid to be polycondensed is other than glutamic acid; salts of hydrochloric acid and of a polyimide derived from the polycondensation of at least one amino acid which is similar to or different from that or those used; acid salts of sulphuric, phosphoric or phosphorous acids or their precursors; phosphoric acid precursors other than phosphoric anhydride or polyphosphoric acids; and Lewis acids; according to an "acid catalyst"/amino acid molar ratio of at least 0.001. Use of the polyimides or of the polypeptide hydrolysates thus obtained in detergent compositions, and detergent compositions containing the said polyimides or hydrolysates.

    • The present invention relates to a stable water-in-oil emulsion for cosmetic, pharmaceutical or hygiene use, comprising an aqueous phase and a fatty phase comprising a silicone oil, characterized in that it comprises an emulsifying system comprising at least one &agr;,&ohgr;-substituted oxyalkylenated silicone of formula (I): in which: R=—(CH2)pO—(C2H4O)x(C3H6O)yR1 where: R1 represents H, CH3 or CH2CH3, p is an integer ranging from 1 to 5, x ranges from 1 to 100 and y ranges from 1 to 50, it being possible for the units (C2H4O) and (C3H6O) to be distributed randomly or in blocks, the R2 radicals represent a C1-C3 alkyl radical or a phenyl radical, 5≦m≦300, and a co-surfactant chosen from the family of glycol mono- and/or diesters and glyceryl mono-, di- and/or triesters, and mixtures thereof. The invention also relates to a composition comprising the above emulsion, and to its applications in the cosmetics, pharmaceutical, dermatological or hygiene fields.
