Abstract: This work aims to study the formation of Surfactant Polyelectrolyte Complexes (SPECs) emulsion formed by mild and natural based anionic surfactant, Sodium Laurylglucosides Hydroxypropylsulfonate with cationic chitosan (CS). The range of CS concentration to stabilize SPECs emulsion at 10%w/w jojoba oil, 0.5%w/w surfactant and pH of 5 were between 0.5-0.7%w/w. The range of surfactant concentration to stabilize SPECs emulsion at 10%w/w jojoba oil, 0.5%w/w CS and pH of 5 were between 0.2-1.5%w/w. The jojoba oil concentration that can be stabilized on SPECs emulsion at 0.5%w/w surfactant, 0.5%w/w CS and pH of 5 were between 10-15%w/w. The suitable pH value for emulsion formation is at 5-5.7 at 0.5%w/w surfactant, 0.5%w/w CS and 10%w/w jojoba oil. The NaCl electrolyte had an influence to deteriorate stabilization of emulsion system. It should not be applied in the formulation. The thickeners (stearic acid, cetyl alcohol, carnuba wax and beeswax) and auxiliary emulsifiers (lanolin PEG-75 and glyceryl monostearate) were used for improving stabilization at minimum 3%w/w of thickeners and 1%w/w of auxiliary emulsifiers. The emulsion systems were destabilized by 3-5%w/w propylene glycol the formulation with CS. However, the emulsion system containing 3%w/w glycerine remains stable. Therefore, the additional ingredients could destabilize the SPECs of emulsion system.
