Kathon cg+ DMDM hydantoin as preservative for shampoo
If i use kathon cg(1.5% MIT/MCIT) with DMDM hydantoin or formalin as shampoo preservative, how much of each preservative should i use?
According to data about Lonzaserve® PC from lonza, a blend of <0.1% DMDM hydantoin+ <1ppm MIT/MCIT can preservative shampoo.
This would be my go to preservative blend if this is true.
