摘要：
This patent application has as purpose the application/utilization of esters and ethers derived from xylitol, obtained by organic synthesis, as alternative emollient, moisturizing, emulsifier and co-emulsifier and preservatives for pharmaceutical, cosmetic and veterinarian products. The molecules required in this invention patent are mainly xylitol esters and ethers associated to the chains of fatty acids and alcohols (FIGS. 1 and 2), applied isolated or in association with other molecules of known preserving and/or moisturizing/emollient actions, such as phenoxyethanol, butylene glycol, glycerin, caprylyl glycol, ethyl hexyl glycerin, phenetyl alcohol, nisin, lactoferrin, among others, as well as in association with other emollient/moisturizing and preservatives for application in cosmetic, pharmaceutical and veterinarian formulations. Some of these associations and isolated applications present important antimicrobial action, such as for example, inhibiting the growth of Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Aspergilus niger and Candida albicans. Also, the present co-emulsifier, emollient, solving and moisturizing properties.
