  • Method of refining glyceride oils
    Patent number: 5516924
    Abstract: The invention relates to a method of refining glyceride oil comprising the step of degumming said glyceride oil, wherein said degumming step is followed by a separation step in which undissolved and non-centrifugable particles are removed from said degummed oil. Preferably said degumming step is followed by a step of holding the degummed oil for such a period of time and under such temperature conditions as to cause agglomeration of said undissolved particles, and for an agent promoting the formation of undissolved particles and/or promoting the agglomeration of the undissolved particles is added to the oil.

  • Fabric softening
    Patent number: 5516438
    Abstract: A method of preparing a fabric softening material which comprises a quaternary ammonium material and at least one C.sub.8-28 alkyl or alkenyl group connected to the molecule via an ester linkage. The process comprises the step of reacting a base material with an alkyl or alkenyl group continuing material, such that at least one alkyl or alkenyl group is connected to the base material via an ester linkage. The reaction between the base material and the alkyl or alkenyl group containing material is carried out in the presence of more than 10 mole percentage excess of the alkyl or alkenyl group containing material to the base material.

  • Method of simultaneously enhancing analgesic potency and attenuating dependence liability caused by exogenous and endogenous opiod agonists
    Patent number: 5512578
    Abstract: This invention relates to a method of selectively enhancing the analgesic potency of morphine and other clinically used bimodally-acting opioid agonists and simultaneously attenuating development of physical dependence, tolerance and other undesirable side effects caused by the chronic administration of said bimodally-acting opioid agonists comprising the co-administration of a bimodally-acting opioid agonist which activates both inhibitory and excitatory opioid receptor-mediated functions of neurons in the nociceptive (pain) pathways of the nervous system and an opioid receptor antagonist which selectively inactivates excitatory opioid receptor-mediated side effects. This invention also relates to a method of using excitatory opioid receptor antagonists alone to block the undesirable excitatory side effects of endogenous bimodally-acting opioid agonists which may be markedly elevated during chronic pain.
