Products

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.

Fatty acid diethanolamide 80%

ALKEST® TW 327 is made up of ethoxylated sorbitan esters,Depending on the starting fatty acid and the degree of ethoxylation,with a wide range of HLB (Hydrophilic-Lipophilic Balance) values are obtained, which provides the formulator with a versatile set of emulsifiers to choose from.

The ALKEST® CSO 540 is composed of surfactants resulting from the reaction of castor oil with ethylene oxide (EO). By increasing the degree of ethoxylation, the hydrophilic character of the molecule is increased (higher HLB), which represents increasing water solubility, cloud points and pour points. This product can be used as emulsifier, antistatic agent, lubricant and solubilizer in various markets and product applications.
