Characterization and stability studies of emulsion systems containing pumice

Abstract: Emulsions are the most common form of skin care products. However, these systems may exhibit some instability. Therefore, when developing emulsions for topical application it is interesting to verify whether they have suitable physical and mechanical characteristics and further assess their stability. The aim of this work was to study the stability of emulsion systems, which varied in the proportion of the emulsifying agent cetearyl alcohol (and) sodium lauryl sulfate (and) sodium cetearyl sulfate (LSX), the n… Show more

“…Além disso, ao longo de 28 dias de estudo, em diferentes temperaturas (Tamb (25°C), T37°C e T45°C), notou-se um valor de espalhabilidade menor para a formulação contendo o ativo quando comparada à formulação veículo. Assim, uma formulação cosmética com uma espalhabilidade adequada costuma ser a formulação de escolha pelo P&D visto que esta possui um sensorial agradável para o consumidor 3 . Com relação à viscosidade de uma formulação cosmética, este parâmetro não deve ter um valor excessivamente alto e nem um valor muito baixo.…”

“…Moreover, during the 28 days study at different temperatures (Tamb -25°C, T37°C and T45°C), a minor amount of spreadability was noticed in the formulation containing the active as compared to the vehicle formulation. Thus, a cosmetic formulation with an appropriate spreadability often is the formulation of choice for R&D as this has a nice feel for consumer 3 .…”

“…Today's hair-styling formulations should meet the properties of humidity resistance and stiffness, combined with the sensory attributes of shine enhancement and good spreadability through hair (Lochhead, 2007). Emulsions used in personal care application, both water-in-oil (W/O) and oil-in-water (O/W) types, need to present the right consistency (rheology) for use, long-term physical stability (2-3 years) under varying conditions of temperature and transportation and functional additives to ensure satisfactory performance (Oliveira et al, 2004;Estanqueiro et al, 2014).…”
