Update to the list of sanitizers and cleaners listed at the start of this thread:
***UPDATE*** Bleach is packaged color coded in kitchen and laundry variations for Japan. The kitchen version is in a green bottle with a pink cap, laundry type in a blue bottle with dark blue cap. I had always overlooked the blue capped bottle assuming it was ammonia or some other chemical not to be confused with bleach The label on the green (kitchen) bleach lists ingredients as: 次亜塩素酸ナトリウム 塩素系,
アルキルアミンオキシド, 水酸化ナトリウム・ アルカリ性 (Sodium hypochlorite chlorine, Alkyl amine oxide, Sodium hydroxide) and the blue bottle lists ingredients as: 次亜塩素酸ナトリウム 塩素系,水酸化ナトリウム アルカリ性
The difference seems to be Alkyl amine oxide which wikipedia lists as a surfactant. I have been using this pink capped bottle in my no-rinse sanitizer solution and never suspected this might be causing head retention issues.
I have had head retention issues that I have not understood the source of. No taste of infection, using specialty grains to improve head retention, and carbonating properly yet my beers seemed to be fairly poor on visual presentation. I think this was possibly the cause for me, but will have to start a new beer to see if there is a difference. Im going to switch to the blue capped bleach from now on anyway, it still has the active ingredients needed.
Cheers!
