  • Publication number: 20190388308
    Abstract: The present invention relates to novel oil-in-water nanoemulsions. The oil phase contains oil selected from the group consisting of triglyceride oil and/or petrolatum as well as C8 to C18 fatty acid; and the aqueous phase contains specific N-acyl derivatives having specific counterions of amino acid salt as emulsifier, glycerol, and water. When (i) there is defined ratio of glycerol to water; (ii) specific counterion for amino acid surfactant and (iii) fatty acid in oil phase. Nanoemulsions are processed in a one-step process yielding droplets of size 20 to 400 nm. In one embodiment, droplets of size 20 to 400 nm can be made using rotor-stator device (in one-step process) and in the absence of pressure based homogenizer. This saves in energy and cost. Compositions prepared according to this processes are also contemplated.

  • Patent number: 7579311
    Abstract: The present invention relates to process for producing bars comprising 20 to 70% by wt. acyl isethionate and 15% to 35% free fatty acid and which is made by process where excess fatty acids made during production of acyl isethionate is removed by neutralization rather than by “stripping”. The bar retains remarkably desirable consumer properties.

  • Publication number: 20050003094
    Abstract: The present invention is directed to a thermally initiated polymerization process. The process provides for heating in a reactor a reaction mixture comprising one or more acrylate monomers to a polymerization temperature ranging from 120° C. to 500°0 C., and polymerizing the reaction mixture into a polymer. Applicants made an unexpected discovery that acrylate monomers can be used as thermal initiators, which makes the process more economical than conventional thermally initiated polymerization processes. The reaction mixture can also include non-acrylate monomers. Several novel steps are also disclosed to control the molecular weight and the polydispersity of the resulting polymer are also disclosed. The polymers made by the low cost process of the present invention have wide application, such as in automotive OEM and refinish coating compositions.
