@ketchito
What is LESS? Was that a typo? Are you referring to SLES? Thanks for the info.

I reviewed the above link you provided. Have you tried testing that formulation? Right now I have the below formula. Is it any good?

SLES 5.00%

LABS 6.50%

CDEA 1.00%

DMDM 0.05%

Colorant 0.01%

Scent 0.10%

Caustic 1.70%

Water Balance

I’m thinking of adding AOS powder to the formulation you provided because there are studies that 80:20 ratio of LABSA and AOS results to high foaming. What do you think?

I think the precipitate you are having is the neutralized salt, SDBS, which is usually used in detergent powders.
