ALKEST® TW 80 K

1 of 33 products in this brand
The ALKEST® TW 80 K is made up of ethoxylated sorbitan esters. The products in the ALKEST® TW line are hydrophilic, having high HLB values. The presence of the polyoxyethylene chain makes the products in the ALKEST® TW line soluble or dispersible in water, which favors their application in oil-in-water (O/W) emulsions, as dispersants/solubilizers of oils and fragrances, and as co-surfactants and humectants in shampoos, hand soaps, and body washes. 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.

Recommended Uses
  • ALKEST® TW line are hydrophilic, having high HLB values. The presence of the polyoxyethylene chain makes the products in the ALKEST® TW line soluble or dispersible in water, which favors their application in oil-in-water (O/W) emulsions, as dispersants/solubilizers of oils and fragrances, and as co-surfactants and humectants in shampoos, hand soaps, and body washes.
  • Because of the high degree of ethoxylation in the ALKEST® TW line, these products also function well as humectants and antistatic agents. Below are some applications of the ALKEST® TW lines per market segment:

Agrochemical

  • ALKEST® TW lines are used as emulsifiers in emulsifiable concentrates, oil-in-water (O/W) emulsions and microemulsions. They can also be used as adjuvants in soluble concentrates and as humectants in wettable powders and waterdispersible granules.

Cosmetics

  • 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 high HLB of the ALKEST® TW products, especially ALKEST® TW 327, combined with their low irritation potentials, makes them excellent choices as co-surfactants in formulations specifically developed as mild products, such as baby shampoos.

Detergents

  • ALKEST® TW lines and their mixtures are recommended as emulsifiers in liquid and paste wax formulas, and as a solvent base for floor and automotive polishing waxes and furniture polish. Tailored HLB emulsification systems are obtainable using ALKEST® TW mixtures
  • Recommended use levels for the ALKEST® TW products with higher HLB. As a general rule, use 25% by weight of the ALKEST® SP / ALKEST® TW combination based on the amount of oil phase to emulsify.
