Application of factorial design in the development of cosmetic formulations with carrageenan and argan oil

Background: Gel-cream formulations used as cosmetics can present various textures. They may be fluid or semisolid, being highly influenced by their composition. These presentations require a complete study to obtain information about the physical stability and consistency of product possible interaction between its compounds. In this context, aimed develop cosmetic using carrageenan argan oil assess through factorial design influencing factors on physical-mechanical properties. Materials Methods: This presents two different moments, totalizing 28 developed. First, 27 were formulated according 3³ understand influences concentrations, processes, interactions raw material. second moment, four selected from factorial: F1 (1% carrageenan, without oil); F2 (2% oil; carrageenan); F3 (without both), F4, formulation with presence both in highest concentration. The F4 was utilized create F5, which same basic composition but added 0.1% NaCl. All studied regarding texture parameters TA.XT Texturometer. Results: natural ingredients presented synergistic action improving properties formulation. It is observe that viscosity index most affected parameter absence variation materials. addition NaCl increased significatively all studied. Thus, higher results for when compared F1, only carrageenan. Conclusions: work has significant contribution once showed use could contribute developing more suitable formulations, besides evidence materials sources, giving subsidies development stable superior performance.
