How to formulate sulfate free body wash with 15% glycerin and 10% oil ?

I tried making a body wash with

sodium lauroyl sarcosinate 20%
disodium cocoyl glutamate 5%
CMEA 0.8%
CAPB 5%
glycerin 15%
sunflower oil 10%
ceteareth 20 2.5%
moisturizers and conditioners.
CDEA 1%
Acrylates copolymer 2%

im getting a stable formula (its been only a day) but the viscosity is very low. 
 
I would like to see if there is any other approach to formulate.

  • Do you want the viscosity higher? I once made a gel cleanser containing 12% oil and thickened with Ultrez 20, xanthan gum (for flow), and PEG-120 methyl glucose dioleate. A couple days' wait gave rise to a nice gel-like lotion texture.
  • Yes. Will your formula hold 15% glycerin along with the 10% oil?

    @Padmavathi ; I think that 15% of glycerin is too high level and almost reduce the viscosity of product try to reduce it.

    I wonder, what is the point of using 15% glycerin?  It is water soluble and will simply be washed away during use without providing any noticeable benefit. 
  • Isn't salt compatible with your formula? I would try to thicken that in addition to/instead of acrylates. You may need to increase CAPB if so.
  • @Fekher, @Perry my client wants 15% glycerin and 10% sunflower oil. 
    @alchemist01 i haven't tried salt to thicken the formula. will do.

    @Padmavathi you supposed to tell clients wich better so you can tell them that with  lower level of glycerin product will be better .

    That product brief by your customer shows that you need to take a step back and bid adieu to this business opportunity. My god those are some crazy numbers that can be accommodated in a shampoo formulation. Shampoo is supposed to get rid of oils, dirt, sebum, etc. and not infuse 10% oil into hair. Let the hair oils and hair serums do the job of oiling in my opinion.
  • @Fekher i tried telling them that but they were very specific about it. I just wanted to see if there was any way i could do it.  
    @Chemist77 its a body wash not shampoo.

    Still @Padmavathi that's a lot for such format

    I don't think it's entirely impossible, as I recently read this: https://www.chemistscorner.com/cosmeticsciencetalk/discussion/5997/oil-base-shampoo

  • There are special materials by BASF that allow formulating a cleanser with a very high oil phase. Those require a special processing technique and would be expensive in general. What you listed above is not going to be stable and is impossible to thicken. Sarcosinate doesn't tolerate oil. And no, this is impossible to thicken with salt.

    I agree it's impossible for the format above, but maybe they will accept something like oil to emulsion cleanser. Cithrol 10 GTIS by Croda. Not going to foam thought.
  • @ngarayeva001 i work for a distributor of BASF. I've used the product you are talking about to make shower oil. My problem here is to stabilize oil and glycerin in the same formulation.
