Swiss Repellent Index
SWISS REPELLENT INDEX (SRI) describes the protection factor of insect repellents and serves as a purchasing aid. The SRI ranges from 1 = low protection to 4 = highest protection, so you can see at a glance which product is right for you and your family. SRI is determined by assessing various indicators such as the active ingredient and the duration of protection against various insects achieved in the laboratory.
