Abstract: Four illuminators A, B, C and D direct collimated illuminating beams to a point O at the centre of a sample 40 and have projections onto the plane of the surface of the sample 40 at points A1, B1, C1, and D1. Angles <AOA1, <BOB1, <COC1, and <DOD1 have the same value of 45~. A camera (41) located directly above the point (O) acquires four images as the illuminators are individually illuminated. A processing section receives the acquired image data on line (42) and, after filtering, a common point distribution is evaluated based on the common points in the light intensity distribution data of two pairs of images with opposite illumination directions (A & C, B & D).  At the same time, an edge enhancing distribution is evaluated based on the opposing value points in the light intensity distribution data for the opposing directions. These two distributions are combined and after thresholding, a binarised distribution is produced which is analysed. From this, pore size distribution, grain size distribution and porosity of the sample can be found.

Abstract: The present invention relates to an improved controlled delivery system that can be incorporated in soap bars to enhance deposition of active ingredients and sensory markers onto skin. The carrier system also provides controlled release or prolonged release of these actives from the skin over an extended period of time. The controlled delivery system of the present invention comprises substantially free-flowing, powder formed of solid hydrophobic, positively charged, nanospheres of encapsulated active ingredients, that are encapsulated in moisture sensitive microspheres. The high cationic charge density of the nanosphere improves deposition of active ingredients onto ski n. The high cationic charge density on the nanosphere surface is created by incorporating a cationic conditioning agent into the solid hydrophobic matri x of the nanospheres, by incorporating a cationic charge ~booster~ in the moisture sensitive microsphere matrix, or by using a cationic conditioning agent in the nanosphere matrix in conjunction with a cationic charge ~booste r~ in the microsphere matrix. The invention also pertains to soap products comprising the controlled release system of the present invention.
