Improving Lotion Texture: Thickness, Slip, and EDTA Concentration

Asked by: mayberich11 On: January 28, 2015 Product Type: Cosmetics

Question

I am making a lotion, but I have two issues with the texture. First, the lotion is too liquid and sometimes separates. Second, it doesn't feel smooth on the skin; it feels sticky or lacks slip. I would like advice on how to fix these texture problems.

Additionally, I have a question about `Disodium EDTA`: is the recommended concentration of 0.2% based on the water phase or the total formula weight?

Answer

Improving Lotion Texture for Thickness and Slip

It's understandable to be frustrated when your lotion doesn't turn out with the desired texture. Based on the formula you provided and the advice from MySkinRecipes Staff, here are the approaches to improve your lotion:

Addressing the Lotion Being Too Liquid

The Staff suggested several methods you can try:

  • Increase Mixing Time: Ensure you are blending or stirring the ingredients for long enough to properly emulsify and prevent separation.
  • Change Emulsifier: If you are making a new batch, consider switching from Light Cream Maker to an emulsifier that provides a heavier texture, such as Soft Cream Maker (which is one option that gives a soft cream texture).
  • Add a Thickener: You can add a gelling agent or thickener like Pro Polymer to help increase the viscosity of the lotion. Alternatively, you could try increasing the amount of the Light Cream Maker you are already using, ensuring sufficient mixing time.

Addressing the Lotion Feeling Sticky/Not Smooth

To enhance the slip and improve the skin feel, the Staff recommended adding the following ingredients:

  • Silicone Group: Such as Cyclomethicone or Silicone Gel Ultra-Clear, which will make the lotion feel smoother and easier to spread.
  • Softening Powders: Such as PowderCream, MatteSilica, or SiliSilk, which will give the skin a soft and pleasant feel after application and prevent stickiness.

Question Regarding EDTA

Regarding your additional question about Disodium EDTA, the Staff confirmed that the specified amount of 0.2% refers to 0.2% of the total formula weight, not just the water portion.

Hopefully, these suggestions will be helpful in refining your lotion formula!
