Feedback on rinse-off hair conditioner
Hello!
I’m new at formulating/manufacturing cosmetics products, so I’ll really appreciate any help with my rinse-off conditioner formula
Problem: My hair (curly, dry) is still a bit frizzy! and not enough conditioned :disappointed:
Formula:
Water 71.2 Cetrimonium chloride 5 stearamidopropyl dimethylamine 3 Argan oil 1 Coconut oil 1 Shea butter 1 Cetyl alcohol 3.5 Stearyl alcohol 2.5 Amodimethicone 2.5 Hydrolyzed Keratin 2 PEG-12 Dimethicone 2 Polyquaternium 7 2 Pantenol 0.5 Parfum 1 Citric Acid 0.8 Phenoxyethanol 1 Questions:
- What would you change to make this formula better?
- Increasing oils % would help?
- heating water+cetrimonium chloride+stearamidopropyl dimethylamine up to 80 C is OK as procedure?
- Adding dimethicone or cyclomethicone would help?
I’m also planning to add about 5% of claim ingredients for marketing purposes.
Thank you!!

Here is what I would change:
1. Lower Cetrimonium Chloride to 0.5% (or lower). I don’t know where you live, but 5% is far too high and exceeds the legal limit in some places.
2. Hydrolyzed keratin can be lowered to claims levels.
3. Polyquaternium 7 will be equally as effective at 1%
4. Not sure if you’ve already made this, but you seem to have a lot of thickener in there. If it works as is, then leave it.
5. 1% seems ridiculously high for your fragrance. I usually use <0.5%.
6. Not sure if this has been challenge tested but I’m not confident that 1% phenoxyethanol will suffice for preservation.

Hey @natzam44 thank you for your answer! Would you swap the cetrimonium chloride for another ingredient? or just leave as it is at 0.5%?

@MariaG I would keep it in at 0.25%

@MariaG I also wanted to ask if that citric acid was in solution? If not, then 0.8% will most certainly be too much. I personally use a 20% solution and check the pH with a pH meter every 2-3 drops for samples (40g).

@natzam44 yes, it is a solution! Will do the 2-3 drop process! Thanks :smiley:
