The market development toward sustainable products is being driven by both the consumer expectations and regulatory requirements. While most consumers are looking for natural personal care products, they are not willing to sacrifice product performance. Aspects like stability, flexibility or ease of formulation (for the formulator) as well as improved skin feel and appearance and easy application (for the consumer) also have a direct impact on product performance. This presentation will identify four critical areas --processing temperature options (hot/hot, hot/cold, hot/hot/cold, cold /cold), processing techniques (emulsion concentrate, one pot process and classical process), oil phase loadings (low and high) and finally application forms (low viscous, spray, lotion cream) -- that will enable formulators to identify viable alternatives to synthetic emulsifiers. A comparison of three known emulsifiers – Glyceryl Stearate; PEG-100 Stearate, Glyceryl Stearate Citrate and Polyglyceryl-6 Stearate; Polyglyceryl-6 Behenate for their flexibility in processing temperature options (hot/cold), processing techniques (emulsion concentrate, one pot process), and finally application form. In this dawning era for greener products, formulators will need to look at emulsifiers that will enable dimensions of flexibility.
