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
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!!
Comments
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.
