My hair wax formulation is a basic emulsion type hair wax which contains 0.06% bamboo charcoal powder and 2% kaolin. You can refer to my formulation below. I have encountered few issues during scaling up to >20kg batch size.
1. Unable to achieve viscosity vs lab batch. I've tried adjusted the homogenization speed, time, and cooling rate.
2. Colour of the big batch size is much lighter than the lab batch. I have to adjust with another 0.06% charcoal to achieve the desired colour. However, the lab batch bulk colour looks more yellowish grey tone while bigger batch looks bluish grey tone. 100% sure it is not rinsability issue or inaccurate weighing. Tried total 0.12% of charcoal in the formulation 2nd time without post adding method, but the colour still came out lighter. Any idea why there is colour difference?
3. Realised there were lots of bubble created when kaolin was added into Carbopol Clear, which later realised it created lots of microbubble in the bulk, but eliminated most of the bubble by vacuuming. Anybody know if kaolin will have any reaction with any of the ingredients below?
Carbopol clear 0.1%
Candelilia Wax 18%
Mineral oil 3%
Ethylhexyl Palmitate 6%
Stearic acid 0.5%
