LECITHIN-BASED MICROEMULSION CONTAINING PROTEOLYTIC ENZYMES AND METHOD OF PERFORMING PERMANENT ENZYMATIC DEPILATION

摘要

The invention refers to depilatory preparations containing: proteolytic enzymes solubilized in microemulsions, formed with lecithin, aliphatic hydrocarbon, alipathic alcohol and buffer solution pH 7 to 9, value corresponding to the pH range near the optimum pH value for the catalytic activity of the proteolytic enzymes, to be applied for permanent enzymic depilation. The application of these preparations will assure, as shown by our experimental studies, more permanent depilation than the one resulting from other depilatory methods. The application of these preparations is suitable for every type of skin (fatty-resistant or dry-sensitive). The present invention introduces the use of microemulsions as a medium for the facilitated penetration of the enzymic activity in the epithelial cells of the skin, as shown by our studies.
