Solid Detergent
Hi Everyone,
I’m new to the site and to formulation. So hoping to get some questions answered.
I’m working on a making a solid dish soap/ detergent instead of liquid form mainly to make the detergent last longer.
First off, is grease cleaning mostly dependent on pH of the detergent? So a pH of 9-10 would clean better than pH 8?
I have a basic formula of SLS, CAB, sodium carbonate and fragrance oil (lemon). I’ve seen videos of people melting the mixture in double boilers to make a paste. I’d like to take this one step further to make a solid “soap” (for lack of a better word). Is this possible?
Upon further research, apparently saponification of vegetable oil could also produce a pH of 8-10. I wouldn’t need to add sodium carbonate unless I wanted to increase the pH even more? I’m wondering if this saponified soap would work well on grease and oil for dish and pot cleaning?
Then I started thinking if I could combine the two techniques and include some fat into my SLS mixture to saponify it into solid soap? But I’m wondering if this would make using SLS redundant since I would already have soap from the saponification.
Thanks in advance and apologies if I sound too naive.
Rick

I think you should have a different approach. If you want your product to perform, you need to start with the basic principles of detergency, type of substrates, detergent-substrate interaction, etc. You could then check what big guys in the marketing are domingo in terms of formulation (they for sure follow those principles I mentioned). Then, understanding all that, you could think about replacing some materiales for more natural ones and compare if they still perform or not. Doing it the other way will only result in an underperforming product with a good marketing story.

Also consider that soap may not be the best choice for dish washing as soap scum can build up in the drains.
