@Pharma  this product will be used for feminine care.  I recently started working for a new company and it is a product they have been making, however they are having trouble scaling it up with that much benzocaine so I have been tasked with resolving this issue.  I am new to formulating OTC products and I am the only chemist here so I am trying to teach myself about these types of products.  Most of my experience is in hair care formulation so if you could recommend any resources that would be beneficial for formulating pharmaceutical applications that would be very much appreciated!

Thank you I will try these recommendations out!

@Pharma thank you for the explanation! and yes it contains hydrocortisone, I need to achieve a consistency similar to that of the cortisone creams so I wasn’t sure if those ingredients above were more so for texture or if they had a different purpose.

@Perry it is an anti-itch cream, similiar to cortizone

thanks everyone! I’ve made up one gel with HEC and it looks nice now, we will see how it holds up overtime.

@chemicalmatt I’m working on a different formulation (a lotion) with veegum R in it now but it doesn’t seem to add any viscosity.  I have it at 1.5%, putting it in the water phase and heating to 75/80C based off a formula from the manufacturer.  This is my first time working with it, can you please advise on the best way to use it?

@Fekher Thanks I will try that out!

@Fekher I’ve tried a few different ways with heat.. I’ve dispersed the carbopol 940 and heated to 50C until hydrated, added the menthol directly in, and then neutralized and also neutralized first and then added the menthol but either way once the carbopol 940 is neutralized the gel separates and the menthol does not go into solution. I’ve also heated the water first and added the menthol, and then added carbopol but same thing happens.
