Objective: In cosmetics and toiletries, new challenges are frequently required, especially the use of ingredients from natural sources. The aim of this work was to formulate an attractive and safe product. Materials and methods: An oil-in-water emulsion was formulated to provide hydrating properties to the skin after sun exposition. Glycolic extract of carrot and tomato was prepared to add to the formula. Both vegetables are rich in pro-vitamin ?A? components and were obtained by mixing the respective juices with propilenglycol (1:1). After a seven day maceration process, they were filtered. Then, this extract was added to a non-ionic-wax selfemulsion formula to obtain the designed product. Liquid paraffin, glycerin, deionized water and methyl-propylparaben were used. A high-revolution mixer was used to prepare the emulsion. Results: Pharmacotechnical, physical and microbiological tests were performed for three months. After this period, no change was found in the main characteristics of the designed product. Conclusion: It is possible to formulate and elaborate toiletry products using natural and low-cost ingredients with beneficial effects. Further in vivo, ex vivo assays will be carried out to demonstrate their beneficial use in humans.
