Silicone-Free Alternatives for Cyclopentasiloxane in Serum

You are currently using Isononyl Isononanoate (LipidSoft™ Lite) and Cyclopentasiloxane in your serum formulation and wish to replace the Cyclopentasiloxane to make a silicone-free claim.

Cyclopentasiloxane is a lightweight silicone emollient known for its fast evaporation and silky, non-greasy feel, helping with the spreadability of the product.

Isononyl Isononanoate (LipidSoft™ Lite) is an excellent non-silicone emollient that was specifically developed to mimic the light, soft, and smooth feel of cyclomethicone like Cyclopentasiloxane. It is non-comedogenic and non-irritating and can be used at high concentrations.

Options for Replacing Cyclopentasiloxane:

1. Increase Isononyl Isononanoate (LipidSoft™ Lite): Yes, you can increase the amount of Isononyl Isononanoate in your formula. Since it is designed to replace cyclomethicone and can be used up to 100%, increasing its concentration from 4% to 8% (to match the total emollient level) or even higher is a viable option to maintain a similar feel. This is often the simplest approach.

2. Use Other Non-Silicone Alternatives: Several other non-silicone emollients can provide a light, smooth feel similar to silicones:

   • LipidSoft™ Cyclo: This emollient was developed specifically to replace Cyclomethicone, offering a similar smooth feel and fast evaporation. This might be the closest alternative in terms of volatility and skin feel.
   • LipidSoft™ Silk: Another natural-derived emollient designed to replace silicone, providing softness and lightness.
   • CocoSilk™ (Coco-Caprylate/Caprate): A lighter ester that can replace cyclopentasiloxane, although it does not evaporate like Cyclopentasiloxane or LipidSoft™ Cyclo.

It is recommended to experiment with increasing Isononyl Isononanoate first, and if the desired texture is not achieved, try incorporating or combining it with other alternatives like LipidSoft™ Cyclo, LipidSoft™ Silk, or CocoSilk™ to find the best fit for your serum formulation.

Remember to test the stability and sensory feel of your final formulation with the chosen replacement(s).
