Why is behentrimonium chloride ok but behentrimonium methosulfate not according to Whole Foods?
Hi, it seems that the Whole Foods Premium Body Care Standards prohibit behentrimonium methosulfate, but allow behentrimonium chloride (they use it in their 365 EVERYDAY VALUE FRAGRANCE FREE SHAMPOO AND CONDITIONER). Yet, the ewg.org rating for the chloride is 3 and for the methosulfate is 1.
Does anyone happen to know why they made this choice?
Perhaps they are concerned about the butylene glycol in BTMS-50. However, behentrimonium methosulfate is available without it in BTMS-25.
It seems there is more research available for behentrimonium chloride than behentrimonium methosulfate:
Would a high percentage of behentrimonium chloride/behentrimonium methosulfate in a conditioner bar concerning to you?:
The research suggests that concentration is an important factor in safety.
