Why the Beads Might Not Be Absorbing

• Compatibility Issues: The solid perfume beads are designed to absorb certain types of liquids, primarily fragrance oils and common perfume solvents like alcohol or glycols (such as Propylene Glycol). Your mixtures contain Propylene Glycol and a substance you refer to as DEB (which might be a type of denatured alcohol or a glycol ether like Diethylene Glycol Monobutyl Ether). While these are generally compatible with many fragrance applications, the "น้ำปรุง" mixture also contains plant extracts. Some plant extracts or the specific solvent used to extract them might not be easily absorbed by these particular beads, or they could interfere with the absorption of other components.
• Incorrect Ratio: Although the product description suggests a 20-30% fragrance ratio, using too little liquid relative to the amount of beads might result in absorption that is not noticeable or takes much longer. Conversely, using too much liquid might mean the beads become saturated quickly or the excess liquid remains unabsorbed.
• Insufficient Contact: Ensure the beads are fully submerged in the liquid mixture and that the liquid can easily reach all the beads. If the beads are clumped together or the liquid level is too low, absorption might be hindered.

How to Troubleshoot and Fix the Problem

1. Check the Ratio: Review the ratio of your liquid mixture to the solid perfume beads. Try preparing a small test batch using a ratio closer to the recommended 20-30% liquid to beads.
2. Test with a Simpler Mixture: If you used the "น้ำปรุง" mixture, try testing a small amount of the beads with a simpler fragrance mixture containing only the solvent (like DEB or Propylene Glycol) and fragrance oil. If the beads absorb this simpler mixture, it suggests that something in the "น้ำปรุง" (likely the plant extracts or their extraction solvent) is causing the issue.
3. Ensure Good Contact: Make sure the beads are well-immersed in the liquid. You can gently stir the mixture occasionally to help ensure even contact between the beads and the liquid.
4. Allow Sufficient Time: While the description mentions absorption in about 1 day, some variations in fragrance composition might require a bit longer. However, after 2-3 days, you should typically see some change if absorption is occurring.
