Patent number: 6926914Abstract: A composition and method for stabilizing proanthocyanidin, especially for preventing, for example, its discoloration by oxidative polymerization. The method utilizes (and the composition contains) proanthocyanidin, and an amino acid having a hydroxyl group or a dipeptide containing said amino acid. Also shown is a drink, food, cosmetic or medicament which contains the composition.Type: GrantFiled: August 30, 2002Date of Patent: August 9, 2005Assignee: Kyowa Hakko Kogyo Co., Ltd.Inventors: Tomoya Takahashi, Asako Kobayashi

Patent number: 4477607Abstract: Cyanoacrylate compositions which employ fumed silicas treated with polydimethylsiloxane or trialkoxyalkylsilane are stable and exhibit an unexpectedly high thixotropic ratio. Such compositions are useful in adhesive applications or, when stabilized so as to prevent polymerization in contact with moisture, in latent fingerprint developing applications.Type: GrantFiled: August 31, 1983Date of Patent: October 16, 1984Assignee: Loctite CorporationInventor: Alan E. Litke

Patent number: 4389512Abstract: Cycloalphatic acrylate compositions and methods of making them are disclosed. The compositions are mixtures containing dicyclopentadiene (meth) acrylate and (meth) acrylates such as the mono and di (meth) acrylates of tri, and tetracyclopentadiene and a mixture of the copolymers of (meth) acrylic acid with adducts of cyclopentadiene with isoprene and/or piperylene and a mixture of poly (meth) acrylates having the repeating unit ##STR1## where R.sup.1 is hydrogen or ##STR2## R.sup.2 is CH.sub.2 .dbd.CZ--C(O)--O-- Z is H, or methyln is 0, 1 or 2 andm is 0 or 1 and when m is 0 there isa double bond present.The compositions are useful to make crosslinkable blends with unsaturated resins or monomers and to make laminates.Type: GrantFiled: May 29, 1981Date of Patent: June 21, 1983Assignee: The Dow Chemical Co.Inventors: Hans R. Friedli, Donald L. Nelson, John L. Massingill, Jr.
