That’s because most hair dye raw materials are hazardous to ship. It costs over $50 to ship a sample out and companies don’t want to get in trouble sending materials classified as “poison” to homes. It’s a liability thing. I doubt you’ll find any reputable distributor to send poisons and environmental hazardous materials to your house.

@Leo just search UL Prospector, many suppliers have free formulations for shampoos.

That depends…what’s the product type, pH, and how much water do you have in it?
Phenoxyethanol is probably your best best though. -
I am almost positive it is the the butters you have in the formula. Those particular rainforest butters are extremely susceptible to oxidation and will turn your formula yellow over time, even at RT. In a 50C oven, obviously that will be accelerated. You may even notice an odor change.

I just finished a project with AHAs. Some tips, make sure you check the stable pH range of your ingredients. AHAs drive a pH very low so you need to have thickeners and preservatives that can sustain activity (benzoic acid/sodium benzoate for example is a low pH preservative). Xanthan gum can also sustain low pH. You will need to add SODIUM Hydroxide to adjust at the end to bring it to at least pH 3. You should also include some additives to reduce irritation. PM me and I can give you a starting formula. The articles attached are some good reading. Happy formulating

Honey also has natural PHAs for very mild exfoliation. The ancient Egyptians also used honey as a topical antibiotic.
Is this formula using honey as its base though? There are many thickeners you can try. I have a formula for a mask that uses ExpertGel EG412 - a thermo gelling polymer. You have to swell it in water first, then you can add your other ingredients. Basically it becomes a gel when it touches the warmth of your skin. You can PM me if you want the formula -
I would try using milder surfactants, for one. You can use amino acid based surfactants which have a lower pH than SLES/SLS. Or you can do a combo to reduce the SLES%. There are also shampoo blends you can use that just need to be embellished a bit (Jeen comes to mind). You can also try adding hydroxymethylpropylcellulose to add slip, viscosity, and foam enhancement.
