| Summary: | Sun protection creams were formulated with a commercial rosemary extract and with thermal waters from different springs in the Northwest Spain. A six month stability study was carried out and microbiological and chemical stability, as well as sensorial characteristics, were evaluated. In all creams, the mesophilic count always remained low (under 10 cfu/mL) and most of them showed greater antioxidant stability than the control cream formulated with distilled water. Color was stable during storage in almost all creams. Sensory analysis showed a quite similar valoration of the creams regardless the sex of the panelists, and small differences were found between consumers aged 30–40 and >40. Formulations elaborated from Outariz and A Chavasqueira thermal waters were preferred to those prepared with distilled water as a control. |
