Abstract

Abstract The invention concerns perfuming and protecting against microbial spoilage products, which are not intended for human or animal ingestion and which comprise at least 25% of water and 0-60% of a surface active material, by incorporating therein a preservative perfume. Preservative perfumes consist for at least 30% by weight of perfume ingredients which need at least 3 inoculations for failure in the individual challenge test. Preferred effective perfumes themselves need at least 5 inoculations for failure in the perfume challenge test.
