Lotion without carbomer… is it possible?
Good day to all of you.
Recently due to supplier start to increase price for our carbomer and also lead time become longer (I’m from Malaysia), my boss start asking “Can we replace carbomer with something else?” I really don’t know. What I know most of the formulation that I found use carbomer as a thickening agent. Does anyone have answer to this question? Really appreciate your opinion and suggestion.Thank you in advance.

Yes it is. You would get thickness from fatty alcohols or else try natural gum also but they tend to form off white cream rather than milky white. Modified gums are available in market which may solve this. Polymeric emulsion stabilizers are also available but in dispersion form. (e.g. Sepiplus 400, Viscoptima, simulgel INS 100 etc.)

Have you tried looking for a different supplier for your carbomer?
Just ask your suppliers if they have an equivalent for the product you are using.
Lots of raw materials are manufactured in Singapore so you may even be able to find one manufactured close to you.

Also, which carbomer are you using? There are quite a few.

Seems a lot more for me to study, I haven’t heard any of example you gave ashish. But I’ll look into it.
Ozgirl, I already discuss with my supplier for equivalent product. Once I get sample from him I will give a try.Bobzchemist, right now I’m using Carbopol 941. Will Utrez 20 be equivalent for my carbopol? -
Carbopol 941 is a traditional one, Ultrez 20 is a advance version which is more easy to disperse as faster as that of 941. But, it is costlier. Other suppliers would be there to provide carbomer for your purpose which would be cheap. But, if you use pemulen TR1 which is a polymeric emulsifier carbomer at lower dosage (0.1-0.3%) can work excellent without using any other emulsifier.

My supplier also suggest us to use Carbopol 940 which is cheaper than 941. Yes you are right Ultrez 20 is more expensive than Carbopol 941. For now as I just received sample of Ultrez 20 and Carbopol 940 will have few trials in lab first. By the way, really appreciate your sharing.

Since you’re working in a commercial facility, be aware that Ultrez 20 has advantages in production that won’t be apparent in the lab. It takes much less time to properly hydrate Ultrez 20, but in the lab, you might only save 10 or 15 minutes - in production, when making a large batch, you could save hours and hours of time and/or headaches, not to mention easily avoiding the dreaded “fish-eyes”.
So, you have to ask yourself (and your management) “How much is an hour of production time worth?”. In a lot of manufacturing facilities in the US, being able to save just an hour or two of production time when making a batch is worth many times the cost of using Ultrez 20 over Carbopol 940 - but it’s different for every factory, so you should check first. -
If you change to Ultrez-20 you will see a change in the sensorials. Better check that’s acceptable first.
