Leathers

  • The ALKONAT® L product line has a molecule with a lipophilic nature from the starting alcohol carbon chain, and a hydrophilic nature, resulting from the ethylene oxide chain. Increasing the degree of ethoxylation increases the hydrophilic nature of the molecule (higher HLB), and as a consequence, altering the solubility in water and the foam, detergency, emulsifying and wettability properties. These surfactants act as emulsifiers, detergents, solubilizers, essence fixers and synthesis intermediates to obtain sulfated surfactants.
  • The ALKONAT® L product line has excellent surface tension reduction power. These products generally do not precipitate in the presence of water hardness ions and are compatible with anionic, cationic and non-ionic surfactants, maintaining and presenting chemical and physical stability in an alkaline and an acid medium and at different temperatures. These surfactants are also compatible with diverse solvents.
  • The use of the ALKONAT® L line during leather processing provides good cleaning of the equipment in question and of the hide handling areas, due to the good emulsifying characteristics.

Storage & Handling

Storage And Handling
  • Pure ALKONAT® L products can irritate the skin. This irritability is considerably reduced with an increase in the degree of ethoxylation. Lauryl alcohol ethoxylates are considered biodegradable and present moderate water toxicity. During handling, use personal protective equipment (PPE). In the case of accidental contact, consult the material safety data sheet (MSDS) and the emergency sheet (MEDS).
  • Store the products in a covered and dry place, far from sources of heat and ignition. The places where chemical products are handled should be well-ventilated, have emergency showers and eye washing areas.
  • ALKONAT® L line products are of difficult combustion but they burn if involved in fire. Check the MSDS in the event of fire.
  • ALKONAT® L products have a clear to turbid aspect with separation of phases at ambient temperature, but they become clear and temperatures between 40° and 60° C.
