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.

Foods

  • ALKEST® TW 60  is widely used as stabilizers and emulsifiers in food applications. In bakery products, they strengthen the gluten network by interacting with the wheat flour proteins, and form complexes with starch that reduce the retrogradation and increase shelf-life. In addition, they are efficient in the stabilization of O/W emulsions and contribute toward greater aeration in cakes, ice-creams and other foods.
  • ALKEST® TW 60 is also used as stabilizers and emulsifiers in foods, recommended for applications that require W/O emulsions and O/W emulsions. They are typically combined with hydrophilic emulsifiers (high HLB) from the ALKEST® TW line to tailor the overall HLB contribution from all the emulsifiers.

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.

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 and its combination based on the amount of oil phase to emulsify.

Storage & Handling

Storage And Handling

ALKEST® TW lines are considered non/low-irritating to the eyes and skin. However, when handling these products in their concentrated form, we recommend proper personal protective equipment (PPE) be used, e.g. PVC gloves, safety goggles, and coat.

In case of accidental contact:

  • eyes: wash immediately with abundant water for at least 15 minutes;
  • skin: remove the contaminated clothing and wash the affected sites with abundant water;
  • ingestion: seek urgent medical care.

ALKEST® TW products should be stored sealed in their original containers, in a sheltered and dry place away from sources of heat or ignition. The areas where chemical products are handled should be well-ventilated with ready access to emergency showers and eyewash stations. The product ALKEST® TW lines are considered non-flammable.
