Is Benzalkonium A Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Benzalkonium A? Is Benzalkonium A safe for nursing mother and child? Does Benzalkonium A extracts into breast milk? Does Benzalkonium A has any long term or short term side effects on infants? Can Benzalkonium A influence milk supply or can Benzalkonium A decrease milk supply in lactating mothers?

Topical maternal application of Benzalkonium A or benzethonium chloride or their presence as a preservative in pharmaceuticals would not be expected to cause any adverse effects in breastfed infants.

A study in Japan randomized 80 consecutive term patients into 4 groups who received either povidone-iodine or benzethonium chloride as a skin disinfectant before delivery and one of these for postpartum vaginal lacerations. Prepartum doses were about 7 mL and postpartum doses were about 0.5 mL of solution. Infant thyrotropin levels were elevated in the infants whose mothers received topical povidone-iodine pre- and postpartum compared to infants whose mothers received benzethonium chloride.[2]
