To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
This is my most disappointing buy of the year. I just started making soap to sell and decided to get this book so I would do everything right. Beforehand, I had read many articles online, but I was waiting for this book, which I believed would be the official "Holy Grail" of soapmaking rules and regulations. Nope! You can get way more accurate information online, with examples, references, and citations. For example, true soaps do not require an ingredienst label, but this book won't just come out and say that, which I find deceptive. And this soap labeling part is just 1 and a half pages of the whole wordy mess. Save yourself the time and trouble, please, and go to the FDA website.
