I've been nagging DH to make liquid shampoos and soaps lol.. but he doesn't want to get into it, coz in order for a liquid soap/shampoo to have good cleansing properties you have to start compromising the naturalness (is that a word? LOL) of the product, such as adding surfactants etc (even naturally derived), and then these ingredients need to be countered with something else etc etc.
I just had a chat with DH in the car about this.. and he denies saying this! LMAO. Truth is, it's a loooooong process to make quality liquid soap, and he couldn't be bothered! However, people do compromise in order to shorten the process (such adding alcohol) and then to keep the consumer happy they add a foaming agent/surfactant such as ones derived from coconut (people love their bubbles)

Anyway.. I got annoyed with him coz I've wanted him to make liquid soap for aaaaages now! and I find out that the 'true' process of liquid soap doesn't go against his principles.. just against his laziness! LMAO. I just did a bit of reading up on it.. and it can be a veeerrry long process indeed.

Something worth looking into tho
