Zinc oil
Zinc oil , Zinkoxidöl , ( latin Zinci oxidi oleum , oleum Zinci , oleum Zinci oxidati ) is a suspension of zinc oxide and olive oil , which in dermatology as a topical drug for wound treatment is employed.
Manufacturing
Zinc oil is only available in pharmacies and can be obtained without a prescription as a finished drug and as a prescription drug that is individually prepared by the pharmacist after prescription by a doctor or at the request of a patient .
According to the German Medicines Codex (DAC) and the New Formulation Form (NRF), zinc oil is a suspension of 50 parts of zinc oxide (300 sieve) in 50 parts of olive oil. The consistency can be increased by adding up to 3% highly dispersed silicon dioxide . Instead of olive oil - with its own strong odor - medium-chain triglycerides (neutral oil , Miglyol 812) that are less sensitive to oxidation can be used.
Storage and shelf life
A cool storage (8–15 ° C) is recommended to reduce auto-oxidation . According to the NRF, the shelf life is six months. Cold storage can impair the homogeneity of zinc oil due to constituents of the olive oil that crystallize out; it must then be warmed to room temperature before use. Zinc oil is an oily suspension and not a solution and should therefore be shaken before use, as zinc oxide sediments and deposits oil on the surface.
Areas of application
Due to the astringent , slightly antiseptic and desiccating (drying) effect of zinc oxide and the oily base, zinc oil has greasy and emollient properties. Indicated for diaper rash and dermatitis in intertriginous area , such softening shed crusts , for skin and wound treatment, such as leg ulcers, eczema , skin redness and irritation, as well as fissures and fissures .
