Described is a single phase clear hydroalcoholic after-shave treatment product containing aloe vera and, optionally, allantoin and a process for preparing same comprising the steps of: (a) either forming: (i) aloe vera gel; or (ii) a product resulting from steam distilling aloe vera leaves and separating the resulting oil phase from the resulting aqueous phase; (b) extracting the oil-miscible aloe vera fraction from the organic phase of the steam distillation product or from the aloe vera gel by intimately admixing therewith a quantity of extraction solvent and physically separating the extract phase from the raffinate phase; (c) separating the extraction solvent from the oil-miscible aloe vera extract phase by means of fractional distillation; (d) intimately admixing the resulting distilled oil-miscible aloe vera phase with a totally miscible perfume oil; (e) admixing the resulting mixture with a polyalkylene glycol, a polyalkylene glycol alkyl ether, a quaternary ammonium salt, a lanolin oil-polyalkylene glycol reaction product, water and, optionally, allantoin or an allantoin-aluminate complex, with the amount of water being in the range of from about 30% up to about 50% by weight of the total mixture.
