Private custom formulation consultancy. I’ve been writing formulas privately for startups, established brands, A-list celebs, and doctors featured on Bravo TV. With over 25 years’ experience with writing clean formulas under the most restrictive distributor & global lists such as Credo, Sephora Clean, Whole Foods, etc.
I am behind the formulas for many brands sold everywhere globally such as Sephora, Ulta, Macys, CVS, Costco, Target, Amazon, Harrods, and countless others. I do not have a website as all my business has been word of mouth and referrals.
Prices depend on the type of formula requested and level of difficulty.

Remaining balance due upon approval of final bench sample. Limit bench samples to three. $150 per sample after that. My lab is in Los Angeles.

Makes no difference. You must be formulating for someone without any restrictions to still be using sulfates. Betaines will also thicken sulfates. Nowadays no one wants salt in their hair products nowadays. I am just used to working with very tight distributor and global restrictions to the point of breathing

First off, does it have to be a gum? Will no other natural thickener be acceptable except the gums you mentioned? I have worked with Lucas Meyer/IFF products for decades and use Siligel often. Siligel isn’t a very robust thickener. It’s more of a sensorial enhancer. From the two, the xanthan gum will give you a lot of viscosity, but the tradeoff is stringiness and a slimy effect. Alternatives that give great viscosity & clarity that are natural would-be CMC (cellulose gum), Inulin, Solagum TARA (Seppic), Natrosol 250HHR, to name just a few.

I would try a different solubilizer that is also a surfactant like Aecosolv Olive & Aecosolv Sunflower from AE Chemie. For 2% fragrance, I would use Aecosolv at 5-6%, then add in the fragrance and mix over very low heat until transparent, then add to your cleanser. If they have a lot of restrictions such as no ethoxylates or PEGS, then for added thickening you will need to use Sepimax Zen from Seppic. To avoid aeration, add it to the batch and do not mix it until the next day. By the following day it would have been absorbed, so all you would need to do it mix slowly until all is incorporated. I do know the Zen is pricey, so I hope they have a good budget!
Btw…that is way too much polymer. The rinse-off will be difficult. Thats why I never liked using it. If I did, I’d keep it at 8%, then add surfactant over it, which will neutralize it, thus eliminating the need for NaOH.. I’ve been doing this an extremely long time. Reach out anytime.
