Quantification of microcapsules deposited in cotton fabrics before and after abrasion using fluorescence microscopy / Ruben Mercadé-Prieto in Industrial & engineering chemistry research, Vol. 51 N° 51 (Décembre 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 51 (Décembre 2012) . - pp. 16741-16749 Titre : Quantification of microcapsules deposited in cotton fabrics before and after abrasion using fluorescence microscopy Type de document : texte imprimé Auteurs : Ruben Mercadé-Prieto, Auteur ; Xuemiao Pan, Auteur ; Angel Fernandez-Gonzalez, Auteur Année de publication : 2012 Article en page(s) : pp. 16741-16749 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Fluorescence  Abrasion  Microcapsule Résumé : Perfume microcapsules for laundry applications are extensively used in home and consumer care products. Capsules have to bind into the fabric during washing and survive the rinsing and drying steps until the desired moment of rupture, usually when in contact with the skin. In order to assess the performance of the microcapsules in the different steps, quantification methods are required. It is reported here the first methodology, using fluorescence microscopy, whereby the number and size of fluorescent microcapsules is individually determined in large fabric areas using image analysis. The performance of fluorescent melamine-formaldehyde perfume microcapsules of two different sizes under abrasion is studied using smooth and rough surfaces, under dry and wet conditions. Survival profiles are obtained with the number of abrasion passes, allowing for characterizing the performance of microcapsules under different conditions. In addition to quantification, fluorescence and optical microscopy allow for identifying where are the capsules deposited in the fabric, as well as which are the safest zones that allow microcapsules to survive extensive abrasion.
