Dead Skin Gel Stickiness Issue

Subject: Re: Dead Skin Gel Formulation

Hello, regarding your dead skin gel formulation and the issue of stickiness on the skin and hair.

The stickiness you are experiencing is likely due to the interaction between Carbomer and the relatively high concentration of Cetrimonium Chloride (CTAC). This interaction forms a complex that creates the peeling effect but can sometimes leave a sticky residue, especially at higher CTAC levels.

To help reduce this stickiness and improve the slip and feel on the skin, you can try adding a small amount of an emollient or slip agent to your formulation.

A common ingredient used for this purpose is Dimethicone. Adding Dimethicone can help to:

• Improve the spreadability of the gel.
• Reduce the tacky or sticky feeling left on the skin and hair.
• Provide a smoother feel.

Recommendation:

Try adding Dimethicone to your formulation. Start with a low percentage, such as 0.5% to 2%, and test the texture. You can adjust the percentage within this range or slightly higher depending on the desired feel and effectiveness in reducing stickiness.

Ensure that the Dimethicone you choose is compatible with your formulation (e.g., water-dispersible or emulsified if needed, although low percentages of lower viscosity Dimethicones can sometimes be incorporated directly or with a co-solvent/emulsifier if the system allows).

Adding a light ester like Isopropyl Myristate or Caprylic/Capric Triglyceride could also be an alternative, but Dimethicone is often very effective for reducing tack.

• Note: While adding an ingredient is a good approach, sometimes slightly adjusting the ratio of Carbomer to CTAC can also help optimize the texture.*

Hope this helps!
