The ALKEST® SP line is made up of sorbitan esters derived from the reaction of sorbitol with fatty acids. Products from the ALKEST® SP line are lipophilic, having low HLB values. The lipophilic nature makes these products soluble or dispersible in oil, favoring their use in water-in-oil (W/O) emulsions and as low HLB emulsifiers used in combination with high HLB emulsifiers in oil-in-water (O/W) emulsions. ALKEST® SP 60 and ALKEST® SP 80, when used in combination with ALKEST® TW 60 or 80, are excellent emulsifiers for beeswax, paraffin, carnauba and their mixtures, promoting stability and homogeneity of formulations. To prepare cosmetic creams and lotions, the selection of fatty acids and degrees of ethoxylation allow many combinations between the ALKEST® SP and ALKEST® TW products to obtain the right balance of emulsifiers for optimum performance and stability.
