Permanent hair waving by artificially shaping with an epoxy-organo-silane
Abstract
Abstract AGENTS FOR IMPROVING THE USUAL METHOD OF WAVING THE HUMAN HAIR HAVE THE GENERAL FORMULA (R-O)A-SI(-CH3)(3-A)-CH2-(C2H4-O)B-CH2-CH<(-O-CH2-) EXAMPLES OF MOST SUITABLE COMPOUNDS ARE 3-(METHYLDIISOPROPOXY-SILYL)-PROPYL-(1)-GLYCIDYL ETHER OF THE FORMULA CH3-(O-C2H4)(1,2,OR3)- AND THE 3-(TRIETHOXY-SILYL)-PROPYL-(1)-GLYCIDYL ETHER OF THE FORMULA (C3H7-O)2-SI(-CH3)-(CH2)3-O-CH<(-O-CH2-) PREFERABLY DISSOLVED IN ETHANOL OR ISOPROPANOL. IN A PREFERRED PROCESS OF APPLYING THESE AGENTS THE HAIR IS FIRST SHAPED, IN THE USUAL WAY, WITH THE AID OF A REDUCING AGENT WHICH SPLITS DISULPHIDE BRIDGES IN THE KERATIN IN THE HAIR, THEN, ACCORDING TO THE INVENTION , A SOLUTION OF ONE OF THE EPOXY-ORGANO-SILANES MENTIONED ABOVE IN ETHANOL OR ISOPROPANOL IS APPLIED TO THE HAIR. THEREAFTER, THE REDUCTION IS REVERSED IN KNOWN MANNER BY MEANS OF AN AQUEOUS HYDROGEN PEROXIDE SOLUTION.
