Hand and Foot Cream Formulation Feedback

Regarding your proposed formula for a hand and foot cream aiming for a very slippery, soft texture that evaporates quickly but leaves a lasting smooth feel:

Your formula includes several ingredients that contribute to the desired texture:

• Cyclopentasiloxane: This is a volatile silicone that provides a lightweight, slippery feel and evaporates quickly, aligning with the initial feel you described.
• Dimethicone Light and Vaseline Petroleum Jelly: These ingredients help provide the lasting smooth and soft feel on the skin after the volatile components have evaporated.
• Glycerin: This acts as a humectant, attracting moisture to the skin and contributing to a soft feel.

The challenge with this formula lies in the high proportion of the oil/silicone/petrolatum phase (approximately 62%) compared to the water phase (approximately 38%).

• Milk Lotion Maker™ is used as the emulsifier, but it is typically designed for formulas with a higher water content (at least 60% water).
• Adding ClayThick™ is a good approach to help stabilize a formula with such a high oil load and low water content, as suggested by the staff.

Regarding the 2% concentration of ClayThick™:

The typical usage rate for ClayThick™ is 0.5-2% for thickening and stabilizing. Using 2% is at the higher end of this range. In the context of your formula's challenging ratio, this amount might be necessary to attempt to achieve stability, but as the staff mentioned, stability cannot be guaranteed without testing.

In summary, your formula incorporates ingredients that can provide the desired sensory feel. However, the high oil-to-water ratio makes it inherently difficult to stabilize. The addition of ClayThick™ at 2% is an attempt to address this, but you will need to perform a test batch to confirm if the formula remains stable and achieves the texture you are looking for.
