Regarding the percentage of Cetrimonium Chloride in a herbal hair conditioner formula: I am in the process of notifying the formula and found a Ministry of Public Health announcement prohibiting the use of this ingredient in products exceeding 2.5% in the formula. However, the formula I intend to notify contains this ingredient slightly above the limit according to the announcement. Therefore, I would like to ask: If I use Cetrimonium Chloride (CTAC) in the formula at 2.5% according to the announcement, what other ingredients can I use to supplement the missing part in the formula to replace the Cetrimonium Chloride (CTAC)? I saw that there is also Behentrimonium Chloride (BTAC), but I am unsure if it can be used as a direct replacement and how. Could you please provide guidance?
