Looking for some advice on my first lotion formula.
Hi there,
,"y":736,"w":0,"h":18,"abs_x":397,"abs_y":1212}”>I am a beginner here, and have been lurking for a little while. I have been working on a “Rice lotion” that is actually doing quite well at making my hands softer and smoother. But, I want to refine it further. There are a few qualities I would like to change. One, I would like to thicken it up a bit, I want a slightly firmer feeling to the cream. Second, it currently feels a bit sticky after application for about 1-3 minutes before subsiding. My original formula used honey, and thinking that might be causing the stickiness, I switched to Glycerin, however, that did not help, so it must be something else. Lastly, I would like to consider using rice water instead of distilled water. This would be distilled water soaked with rice for about 10 minutes. I am not sure if this can be properly preserved, though, and I worry about shelf life.

Try adding a little alkyl esters or cetyl ester for more slip. Just 1% can make a difference.

I would add stearic acid to thicken and phenoxyethanol/ethylhexylglycerin or phenoxyethanol/caprylyl glycol to preserve it.
-
I was going to recommend adding xanthan gum but you’ve got that in 2nd version

I’m curious with your formulation. In using Ginger Root Extract, does it add color to your emulsion? Or does the extract have any color?
I think the wax is making it sticky. -
Your preservative needs to be stronger. That particular one has some gaps in coverage.Ascorbic Acid will not be stable in that product also. It will oxidize (likely evident by a color change) fairly quickly. -

Actually, the extract has a dark orange coloration, but it doesn’t seem to effect the color of the emulsion. It still comes out very white.

Do you recommend a particular preservative in this case?

When you have bug food in your formula and make it in your kitchen you should use very strong preservation system: Germaben II, Germall Plus, or Phenonip + EDTA.
When you use vegetable oil you need an antioxidant: BHA, BHT or at least tocopherol (not the acetate form). -
Thanks for all the feedback. I’ve taken a lot if it into consideration and I think I will be switching the preservative to phenoxyethanol/ethylhexylglycerin, using Ferulic Acid as an antioxidant (derived from rice), and I think I will try Montonov L as an emulsifier with rice bran wax as a thickener.

I would not select Ferulic acid as my primary anti-oxidant for simple marketing reasons (derived from rice). It is much more expensive than Tocopherol and really adds nothing additional. You must balance efficacy and cost with marketing.

Thank you for your response. For your preservative I agree with @ng@ngarayeva001. You can use Phenonip as your preservative. That’s what I’m using as my preservative.
