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.

The ULTRAPEG® product line is made up of ethylene oxide polymers. It is represented by the following general formula: HO(CH2CH2O)nH According to the degree of ethoxylation(n), products with different molecular weights and melting points can be obtained, which allows the use of these products in various applications. The hydrophilicity of the polyoxyethylene chain from the ULTRAPEG® product line allows for the obtention of a hygroscopic polymer which is highly water soluble. By varying the molecular weight, liquid or solid products may be obtained, covering a wide range of viscosities and consistencies.
