Laundry detergent, floor deodorizer, shower gel, scented candles, aromatherapy sprays, reed diffusers, and perfumes—are oil-based or water-based fragrances used?
| Product | Recommended Fragrance System | Key Reasons |
|---|---|---|
| Laundry Detergent | Oil-based (oil-soluble) | Longer-lasting scent on fabrics; better encapsulates fragrance, slowing evaporation during wash and drying. |
| Shower Gel / Body Wash | Water-based (water-soluble) | Compatibility with water-based formulas; ensures clear solution, even dispersion, and avoids oil droplets on skin. |
| Floor Deodorizer | Depends on formula base | Follows "like dissolves like": Use water-soluble for water-based sprays; use oil-soluble for solvent/oil-based cleaners. |
Detailed Breakdown
-
Laundry Detergent: Oil-based fragrances are preferred. The oily components help the scent adhere to fibers and survive the rinsing process, providing a longer-lasting smell on dry clothes. Typical usage is between 0.3% to 1.0% of the formula.
-
Shower Gel: Water-based fragrances are standard. Since shower gels are primarily water and surfactants, water-soluble fragrances integrate seamlessly, maintaining product clarity and lather quality without leaving a greasy feel. Note: Fragrances can be skin sensitizers; for sensitive skin, fragrance-free options are advisable.
- Floor Deodorizer: The choice is formula-dependent. Match the fragrance to the carrier:
For aqueous or water-alcohol solutions: Use water-based fragrances.
For solvent-based or oily cleaners: Use oil-based fragrances.
Some natural deodorizers use essential oils (oil-soluble) for both scent and antimicrobial properties.
How to Make the Final Decision
-
Cost: Oil-based fragrances are often more expensive.
-
Regulations: Ensure fragrance ingredients comply with regional safety regulations for each product type.
-
Performance Testing: Always conduct small-scale tests within your specific formula to check for stability, scent throw, and longevity before full production.
