  • Stable injectable .beta.-carotene micellar solutions and their preparation
    Patent number: 4435427
    Abstract: A process for the preparation of .beta.-carotene micellar solutions, wherein a non-ionic emulsifier which is suitable for the preparation of micellar solutions is heated at from 160.degree. to 180.degree. C. and a total of from 20 to 30% by weight, based on the emulsifier, of .beta.-carotene is introduced in the presence of a conventional antioxidant, the hot homogeneous mixture is cooled rapidly to below 100.degree. C. by adding water, and the formulation is brought to the desired concentration of from 3 to 6% by weight by adding further water, and the .beta.-carotene micellar solutions obtained by this process. The non-ionic emulsifiers used in this process have an HLB value of from 12 to 16, and are in particular oxyethylated triglycerides of fatty acids of 12 to 18 carbon atoms containing 20-60 oxyethylene units. Parenteral admininstration of the stable .beta.-carotene micellar solutions according to the invention to cattle relieves the disturbed estrus cycle and impaired fertility caused by .beta.

  • Preparation of a vitamin E dry powder
    Patent number: 4262017
    Abstract: A vitamin E dry powder, which contains a protein colloid and a disaccharide as carriers, is prepared by dispersing a vitamin E ester in a residual liquor, low in alkaline earth metal ions and rich in lactose, from the production of lactose, in the presence of from 2 to 30% by weight, based on the solids content of the residual liquor, of a caseinate, and spray-drying the dispersion.The vitamin E dry powder thus prepared is stable, easy to dose and physiologically safe, so that it can be used for any desired purpose.
