Seeking transparency
Hi, I am having trouble getting my wash transparent , I guess the reason may be xanthan gum as I use it to enhance viscosity, So Can you suggest any alternative?!
Taking in consideration that CMC , Carbomer and HEC are the only ones available in my Country, If Carbomer is the one will it be affected by the acidity of my additives ? -

@Soona for having help write your formulation.

There are many different grades of HEC and you should be able to find some options with high clarity. Generally, carbomer will lose its viscosity in formulations with high surfactant or salt levels.

Generally agreed, but there are carbomers that work suitably well with surfactants and salts - we’re all still assuming what level of surfactants are being used, or whether or not there’s co-formulants that are resulting in a lack of clarity. I think @Soona disclosing some of their formulation would help.

@Soona As other members mentioned, it’d be better if you disclose more details about your formula, so it can be better assesed. Just one thought, usually HEC gets more clear when you increase pH since it helps “remove” its acidic particles envelop, so when you mention the acid environment of your formula, makes me wonder if the system was acid at all times.

Propylene glycol. 2%

@Soona actually it is really easy to enhance viscosity of your system without gum or carbomer you just need to add adequat level of salt to have viscous clear liquid soap.

@Soona Providing that your Salicylic acid is propperly dispersed, then the Xanthan gum might be to blame for the loss in clarity. You could actually search for a xanthan gum for clear products. Also, betaines can behave as cationics at low pH, and that could also impact clarity (and over time, a precipitate can form and settle). I’d use Cocamidopropyl betaina instead of Coco-betaine since I believe CAPB behaves as a zwitterion at higher pH than Coco-betaine.

Instead of laying the blame on Xanthan Gum or other thickeners, first blame Salicylic Acid.Salicylic Acid is notorious for its recrystallisation in water. It is a very difficult chemical to work with.I am not sure whether SLES can solubilise SA properly or not. I have no experience in making SA wash/shampoo.Is heat applied?Get this resolved first before worrying about thickeners.
