Well, lets see. Hmmm. The brand name (Clorox) would tell their chemical suppliers (whomever that may be) what to put in it, and what concentration of each ingredient to use. Clorox has been around since 1957, you would think Clorox, or its parent company (Procter & Gamble), would know what to use in proper quantity to produce a useful product.
And Clorox, along with its parent company, have the resources and can easily analyze the components of other companies cleaning solutions, and make copies of them as needed. And since none of the individual chemical compounds in Clean Republics products are patented (or the patent has expired in the case of some anti-bacterial ingredients), there is nothing to prevent that. Branding is everything though, so major companies can use smaller suppliers to source their ingredients, to no ill effect. So Clorox and other companies use smaller companies to supply them with some ingredients and mixtures as needed.
It is not unusual for companies to contract other companies to produce constituent components of their products. I doubt ByoPlanet actually makes the bottles they use, and I doubt ByoPlanet has injection molding machines to make the parts for the sprayers. Hypochlorous acid is best made on site though for bottling, as the shelf life (even with stabilizer) is relatively short.
