Feedback on Hair Conditioner Formula

Subject: Feedback on Hair Conditioner Formula

Hello,

Thank you for sharing your hair conditioner formula and asking for advice. Here is some feedback:

1. Total Percentage: The sum of the percentages in your formula is 101.5%. The water percentage should be adjusted to be the balance to 100%. Based on your list, the sum of other ingredients is 73.3%, so the water should be 26.7% (100 - 73.3). Please correct the water amount.
2. HairPLEX™ (Bis-Aminopropyl Diglycol Dimaleate) Concentration: The concentration of HairPLEX™ at 30% seems extremely high for a standard rinse-off conditioner. Typical usage levels for Bis-Aminopropyl Diglycol Dimaleate in conditioners are significantly lower (often 1-10%). Using such a high concentration might not provide proportionally greater benefits, could increase cost significantly, potentially affect the formula's stability or texture, and might even cause irritation at this level. We strongly recommend checking the supplier's recommended maximum usage rate for this specific product. You might consider reducing this percentage significantly.
3. Overall Formula Composition: Aside from the points above, the formula contains a good mix of conditioning agents (BTMS, Cetearyl Alcohol, oils, butters), humectants (Glycerin, Panthenol, Aloe Vera), proteins (Hydrolyzed Keratin, Collagen), and other interesting actives (Hair-Prebiotic, HydroAlgae). This combination should result in a highly conditioning product.
4. pH Adjustment: It is crucial to adjust the final pH of the conditioner to the acidic range, typically between pH 4 and 5, using Citric Acid. This pH range is optimal for the performance of cationic conditioning agents like BTMS and helps to smooth the hair cuticle.
5. Compatibility: Most ingredients listed are generally compatible with a cationic emulsifier system. However, for the proprietary ingredients (HairPLEX™, Hair-Prebiotic™, HydroAlgae™), it is always best to check specific compatibility data provided by the supplier if available, especially concerning the high HairPLEX™ concentration.
6. Testing: We recommend making a small test batch first to evaluate the stability (e.g., separation over time, viscosity changes), texture, and performance on hair before making a larger batch.

In summary, the formula is generally feasible with some important adjustments, particularly correcting the water percentage and reconsidering the high concentration of HairPLEX™.

We hope this feedback is helpful!
