  • Publication number: 20140377364
    Abstract: A spray-chilled particulate delivery system that has a crystalline matrix structure and comprises a volatile hydrophobic active ingredient and a carrier material selected from the group consisting of erythritol and mannitol and mixtures thereof wherein, relative to the total weight of the carrier material, 75% or more of the carrier material is in crystalline form. The process for preparing the delivery system comprises the steps of (i) forming a melt of a carrier material selected from the group consisting of erythritol and mannitol and mixtures thereof (ii) incorporating a volatile hydrophobic active ingredient into the melt (iii) forming a melt-mixture comprising an emulsion, dispersion or suspension of the volatile hydrophobic active ingredient in the melt (iv) forming discrete particles of the melt mixture, and (v) cooling the discrete particles, so as to form the crystalline delivery system.

  • Publication number: 20130028976
    Abstract: A process for preparing a spray-dried product for improving the rate of dissolution of the active ingredient. The process includes mixing a crystalline active ingredient, which has a dissolution rate in unstirred water at 25° C. of greater than 15 minutes at a concentration of 14 ppm of the active ingredient, with a starch derivative, a second carrier material, and optionally, xanthan gum, to form a suspension, dispersion or solution of the active ingredient; homogenizing the mixture at a pressure of at least 4000 psig (2.758×107 Pa); and spray-drying the homogenized mixture to provide a spray-dried active ingredient that has an increased dissolution rate in water compared to the unencapsulated active ingredient.
