Abstract
A fragrance composition having antimicrobial activity comprises between 3 and 20% phenolic compounds, and between 20 and 80% non-aromatic terpenoids. The fragrance composition may also, either alternatively or additionally, include essential oils containing phenolic compounds as a major constituent, and/or essential oils containing non-aromatic terpenoids as a major constituent. The fragrance composition further has an Odor Intensity Index of less than 100, and an Odor Evaluation Acceptability Index of greater than 50. The fragrance composition is suitable for use in a variety of products.
Claims18
A fragrance composition having antimicrobial activity, comprising:
- between 3 and 20% of a phenolic compound;
- and
- between 20 and 80% of a non-aromatic terpinoid;
- wherein said fragrance composition has an Odor Intensity Index of between 110 and 130, and said fragrance composition has an Odor Evaluation Acceptability Index of greater than 50, and said fragrance composition satisfies at least two of the following four criteria
- a:
- said fragrance composition achieves a Minimal Inhibitory Concentration (MIC) in media at or below normal use concentration within two days;
- b:
- said fragrance composition reduces the microbial number by at least 1.5 log cfu/ml within 30 minutes at ambient temperature at or below normal use concentration;
- c:
- said fragrance composition at normal use concentration reduces the microbial number by at least 1.5 log cfu/ml within 30 minutes at product use temperature;
- d:
- said fragrance composition at normal use concentration reduces or inhibits microbial growth.
