  • Publication number: 20230338268
    Abstract: Ethylcellulose dispersions in water are film forming compositions that have found use in personal care applications. Conventional methods can require that aqueous dispersions of water-insoluble polymers such as ethylcellulose be obtained using surfactants such as sodium lauryl sulfate (SLS). There is a desire to reduce the degree of consumer exposure to SLS in personal care products. The present invention describes ethylcellulose dispersions comprising surfactants to substantially replace sodium lauryl sulfate. The present invention also describes methods of reducing or substantially eliminating SLS in personal care products that comprise ethylcellulose dispersions.

  • Publication number: 20230072225
    Abstract: In one aspect, the present invention is directed to a method of making a controlled release solid dosage form having an ethylcellulose coating layer, which layer comprises a coalescing agent which is an organic ester having an HLB Value of from 3 to 8. The use of such coalescing agent permits the formation of an effective controlled release coating without the need for a further curing step after the coating process. In other aspects, this invention relates to an aqueous dispersion useful in such method; as well as to the coated dosage form produced.

  • Patent number: 10590207
    Abstract: The present invention is directed to a process for obtaining at least one of fucoidan and laminarin from live, harvested seaweed, wherein the process comprises the steps of: (i) harvesting seaweed comprising fucoidan and laminarin to obtain live, harvested seaweed, wherein the live, harvested seaweed exudes to form an exudate solution; (ii) collecting the exudate solution from the live, harvested seaweed, wherein the fucoidan and laminarin are dissolved in the exudate solution; and (iii) separating the at least one of fucoidan or laminarin from the exudate solution.
