Question
I would like to inquire about making an air freshener spray for sale.
The formulation is as follows:
- Alcohol 95% (70%)
- Distilled Water (15%)
- Fragrance (15%)
Is it necessary to add a preservative? If so, please recommend a suitable preservative for this product and the usage percentage.
Thank you.
Answer
Based on the formulation you provided for the air freshener spray:
- Alcohol 95% (70%)
- Distilled Water (15%)
- Fragrance (15%)
The high concentration of alcohol (70% of 95% alcohol) in this formula is sufficient to act as a self-preservative. This level of alcohol effectively inhibits the growth of microorganisms.
Therefore, based on this specific formulation, you generally do not need to add a separate preservative for microbial stability.
