For carbomer, I used trolamine to bring up the pH to form a gel. I also used NaOH to bring up the pH to form a gel.

I am developing a skin care line for a company, trying to figure out how to charge the company.

Your formula does not have effective lightening ingredients in it. You need kojic acid/vitamin C/niacinamide etc to have lightening effect. Beside, you are formulating a soap to be washed off in a minute. It does not make sense to apply a lightening ingredient and wash it off right away.

What ingredient do you want in the soap for lightening? Provide more details on the soap product.

Basically the company just provided me with examples of commercial products they liked; they are looking for a natural skin care line with plant extracts. I need to source the material, develop formula for 4 products (not too complicated), and conduct stability studies.
They want to focus on a gentle cleanser, toner to help with dark spots and skin tone, vitamin C serum, and s non-greasy moisturizer to help with wrinkle.
