- Résumé
- "This study examines the effectiveness of smoke odour reduction on a painting on canvas using (2-hydroxypropyl)-ß-cyclodextrin (HPßCD). Different concentrations of HPßCD were compared to a proprietary, commercially available product with cyclodextrins as the active component in odour reduction, Febreze® Fabric Refresher: Free. Two methods of application by cotton swab and by spay of treatment solutions were compared. Odour analyses of control paint on canvas samples were compared with treated and not-treated samples by method of seven panelists ranking the odour intensity of the headspace created. Panelist suggested no preferable treatment solution or method of application, but did conclude a reduction of odour with all treatment solutions. Six sample sets or varying paint material composition and age were created and treated with HPßCD and the proprietary solution. Treated paint samples were compared to controls by colourimetry using a Konica Minolta Spectrophotometer CM-700d under D65 illumination source to obtain colour readings in the CIE L*a*b* 2000 colour space. Readings were taken before and after treatment, and subsequently after artificial aging. Calculated E values were below the threshold of human perceptibility both before and after treatment and when corrected for the effect of artificial aging, with minimal exceptions. This showed that treatment solutions of HPßCD and the proprietary solution do not adversely affect the colour of a variety of fully cured paint films immediately after application or after subsequent artificial aging."
