PCT No. PCT/EP95/00609 Sec. 371 Date Sep. 27, 1995 Sec. 102(e) Date Sep. 27, 1995 PCT Filed Feb. 20, 1995 PCT Pub. No. WO95/22590 PCT Pub. Date Aug. 24, 1995An ultrapure egg oil is prepared starting from dried and powdered avian or reptilian egg yolk by means of extraction with the aid of fat solvents, followed by two-step ageing, first at ambient temperature and then at a lowered temperature, separating off and centrifuging off the less viscous phase formed and again separating off the less viscous component. This component is, if appropriate repeatedly, mixed with demineralized water and heated, and, after cooling, the less viscous phase is separated off and again centrifuged, the less viscous component is again separated off and held at a lower temperature, the phases are again separated, and the less viscous component which has been separated off is recentrifuged. This again results in phase separation, the less viscous component which has been separated off being the end product which is a yellow to reddish, fluid oil which can be stored without preservatives. The ultrapure egg oil prepared by this process can be used for the treatment of skin burns, including sunburn, and for regenerating the skin in cosmetic products.
