  corn oil is used as a carrier oil, it has average emollient properties. Although not particularly prone to cause allergies, it is also not widely used in cosmetic formulations. It is considered somewhat comedogenic. Corn oil is obtained from the wet milling of corn.

• 생산 방법

  Refined corn oil is obtained from the germ or embryo of Zea mays Linne(Fam.Gramineae),which contains nearly 50% of the fixed oil compared with 3.0–6.5% in the whole kernel. The oil is obtained from the embryo by expression and/or solvent extraction. Refining involves the removal of free fatty acids, phospholipids, and impurities; decolorizing with solid adsorbents; dewaxing by chilling; and deodorization at high temperature and under vacuum.

• 일반 설명

  Clear light yellow or yellow oily liquid. Faint taste. Faint odor.

• 공기와 물의 반응

  Insoluble in water.

• 반응 프로필

  On prolonged exposure to air, CORN OIL thickens and becomes rancid. CORN OIL is sensitive to light.

• 화재위험

• Pharmaceutical Applications

  Corn oil is used primarily in pharmaceutical formulations as a solvent for intramuscular injections or as a vehicle for topical preparations. Emulsions containing up to 67% corn oil are also used as oral nutritional supplements; see also Section 18. When combined with surfactants and gel-forming polymers, it is used to formulate veterinary vaccines.

• 농업용

  Corn oil is an adjuvant used in herbicide sprays. It improves their function by improving wetting, reducing evaporation, increasing penetration and enhancing deposition and compatibility. Corn oil is not phyto-toxic; it is added for better penetration in plant leaves.

• Safety

  Corn oil is generally regarded as a relatively nontoxic and nonirritant material with an extensive history of usage in food preparation.

• 저장

  Corn oil is stable when protected with nitrogen in tightly sealed bottles. Prolongedexposureto airleads tothickening and rancidity. Cornoilmaybesterilizedbydryheat,maintainingitat150°C for 1 hour.
  Corn oil should be stored in an airtight, light-resistant container in a cool, dry place. Exposure to excessive heat should be avoided.

• 비 호환성

  The photooxidation of corn oil is sensitized by cosmetic and druggrade samples of coated titanium oxide and zinc oxide.
