The irritation experienced by many males resulting from shaving with a razor and/or a depilatory has been well documented. There are several causes, the most outstanding being the tendency of the clipped hair to curl and grow inward beneath the skin surface. The shaved surface then bumps as the combined result of shaving irritation and clipped hairs which have not grown straight through the skin. The action of an astringent solution works to eliminate and prevent shaving irritation. The addition of ALUMINUM POTASSIUM SULFATE DODECAHYDRATE to ISOPROPYL ALCOHOL causes the pore size of the shave surface to be reduced and gives the topical antiseptic needed to eliminate inflammation. The reduction of pore size denies the clipped hair the room to curl inward therefore causing it to grow straight through the skin surface which, essentially, prepares it for clipping again. The following proportions of each ingredient are used to make the after shave solution: To 95 ML. Of 70% by volume Isopropyl Alcohol is added 5 grams Aluminum Potassium Sulfate Dodecahydrate. The mixture is allowed to sit for 2 hours. The resulting solution is then filtered to recover 0.6 grams unreacted ALKO 8S2 12H20. To the resulting solution is added 5 Ml. Concentrated aromatic oil drop wise over a period of 30 minutes. The solution is stirred constantly during this addition. The resulting solution is a fragrant, topical antiseptic, astringent mixture which eliminates the bumping caused by the use of a razor and/or a depilatory.
