Patent number: 6471954Abstract: A method for the production of a vitamin-A containing cream comprising the following steps: a) a first mixture—consisting of a number of water-soluble substances such as glycerine and extracts of plants—is mixed together during heating and comminution until the mixture has a temperature of about some 80° C., preferably 83° C., b) a second mixture consisting of a number of oil-soluble substances, including emulsifiers, and squalane and vegetable oils such as avocado oil are mixed together during heating until the mixture has a temperature of about some 80° C., preferably 83° C., c) said first mixture is then gradually added to said second mixture during high-shear-mixing with decreasing number of revolutions—from about 5000 rpm to about 3300 rpm—until the temperature of the mixture slowly has decreased to about some 50° C., preferably 51° C.Type: GrantFiled: January 24, 2001Date of Patent: October 29, 2002Assignee: Cortex Technology ApSInventor: Flemming Kjærgaard Christensen

Patent number: RE38827Abstract: This invention is related to an adhesive composition which may be used to bond or seal tissue in vivo. The adhesive composition is readily formed from a two component mixture which includes a first part of a protein, preferably a serum albumin protein, in an aqueous buffer having a pH in the range of about 8.0-11.0 and a second part of a water-compatible or water-soluble bifunctional crosslinking agent. When the two parts of the mixture are combined, the mixture is initially a liquid which cures in vivo on the surface of tissue in less than about one minute to give a strong, flexible, pliant substantive composition which bonds to the tissue and is absorbed in about four to sixty days. The adhesive composition may be used either to bond tissue, to seal tissue or to prevent tissue adhesions caused by surgery.Type: GrantFiled: November 14, 2002Date of Patent: October 11, 2005Assignee: 3M Innovative Properties CompanyInventors: Thomas H. Barrows, Terry W. Lewis, Myhanh T. Truong, Matthew T. Scholz
