Bests & Worsts Reviews from Amazon

I initially purchased the 32oz. ready-to-spray bottle (also for sale on Amazon) and used it to save my Aloe Succulents. I left a 5-star review for the ready-to-spray soap posted around Dec. 27, 2014 if you would like to read it. But this review is to highlight a significant difference between the ready-to-spray bottle and this concentrate. In short, the ready-to-spray bottle has 2% of the active ingredient, but if you follow the instructions on the concentrate bottle, you will end up with a 1% solution. I contacted the company and got a response back. The following is my question and afterwards will be the response from Safer Brands. QUESTION: Dear Safer Brands, There seems to be a big difference between the dilution ratio of the concentrate when compared to the ready-to-spray bottle. The premixed 32 oz. bottle says it contains 2% of the active ingredient (potassium salts of fatty acids) by weight. So for every 98 oz. of water, you would need 2 oz. of the PURE active ingredient. BUT, the concentrate is NOT 100% pure active ingredient. It is 50% active ingredient. So in reality, for every 96 oz. of water, you would have to add 4 oz. of this concentrate to get the same 2% ratio of active ingredient as the premixed bottle. But you instructions recommend adding 2 oz. of the concentrate for every 100 oz. of water, giving you a 1% ratio. (Or 2.5 oz. for every gallon. A gallon consists of 128 oz. or roughly 25% more than the 100 ounces used for my calculation. So adding 25% more to 2 oz gives you 2.5 oz. But in order to match the 2% active ingredient concentration of the premixed bottle, you would need 5 oz. of this concentrate per gallon of water.) I received the following response from Safer Brands: Thank you for contacting Safer® Brand. We are happy to provide more information on our products. Your calculations are correct that the Ready-to-Use has 2% active ingredients while the concentrate has 1%. We did efficacy testing when creating the concentrate and found that a 1% active ingredient is very comparable and has the added benefit of being more gentle to plant species that are more sensitive.
