Abstract
The present invention relates to a silica gel-based composition capable of changing color when placed in contact with alcohol vapors. Said composition is particularly useful for preparing devices for the detection of alcohol, for example devices for carrying out an alcohol test on samples of air exhaled by individuals when subjected to checks by the police or competent authorities.
