ETHYLENEGLYCOLSTEARATES

ETHYLENEGLYCOLSTEARATES Chemische Eigenschaften,Einsatz,Produktion Methoden

• Chemische Eigenschaften

  The USP32–NF27 and PhEur 6.0 describe ethylene glycol stearates as a mixture of ethylene glycol monoesters and diesters of stearic and palmitic acids, containing not less than 50% of monoesters produced from the condensation of ethylene glycol and stearic acid, of vegetable or animal origin.
  Ethylene glycol stearates occur as a white or almost white waxy solid.

• Vorbereitung Methode

  Ethylene glycol stearates are produced from the condensation of ethylene glycol with stearic acid 50 of vegetable or animal origin.

• Pharmazeutische Anwendungen

  Ethylene glycol stearates are used as stabilizers for water-in-oil emulsions, although they have poor emulsifying properties. They have emollient properties and are also used as opacifying, thickening, and dispersing agents.
  In cosmetics, ethylene glycol stearates are used as a ‘fatty body’ for lipsticks, as pearling agents in opalescent and cream shampoos, and as additives for tanning lubricants.

• Sicherheit(Safety)

  Ethylene glycol stearates are mainly used in cosmetics and topical pharmaceutical formulations, where they are generally regarded as relatively nontoxic and nonirritant materials.

• Lager

  Ethylene glycol stearates should be stored in a cool, dark place, protected from light.

• Regulatory Status

  Included in nonparenteral medicines licensed in Europe.
