Question

I have a formula for a 'Silky' product with the following ingredients:

  • Cyclopentasiloxane
  • Dimethicone
  • Cyclomethicone
  • Perfume
  • Vitamin E Acetate

Could you please explain what this 'Silky' product is and provide guidance on this formulation? Specifically, is it possible to add boiled ginseng water to this formula?

Answer

Silicone Serum Formulation Guidance

Based on the ingredients you listed (Cyclopentasiloxane, Dimethicone, Cyclomethicone, Perfume, Vitamin E Acetate), this appears to be a formula for a silicone-based serum or hair/skin oil, often referred to as 'Silky' due to the feel silicones provide.

Your list provides the ingredients but not the specific percentages or a complete formulation method. Here's a general guide based on the typical properties and usage of these ingredients:

1. Proportions and Mixing

Exact proportions depend on the desired feel and performance, but here are typical usage ranges for these ingredients in a silicone serum:

  • Cyclopentasiloxane / Cyclomethicone: This is a light, volatile silicone that provides a dry, silky feel and helps spread the product. It evaporates quickly. Typical usage is 1-20% in a skin/hair serum, but can be used at higher percentages (up to 99%) depending on the desired feel and evaporation rate.
  • Dimethicone: This is a non-volatile silicone that provides lasting slip and smoothness. The viscosity (like 350 cSt) affects the feel; higher viscosity means a heavier, more conditioning feel. Typical usage is 0.5-10%.
  • Vitamin E Acetate (Tocopheryl Acetate): Used as an antioxidant for the skin and the formula itself. It is oil-soluble. Typical usage is 0.1-1%. Using more than 0.5% might feel sticky.
  • Perfume: Added for fragrance. Usage varies depending on the specific perfume, but typically 0.1-1%.

Mixing Method:

Since all these ingredients are oil/silicone soluble, mixing is straightforward:

  1. Combine Cyclopentasiloxane, Dimethicone, and Vitamin E Acetate in a container.
  2. Stir gently until fully mixed. Avoid excessive heat.
  3. Add the Perfume and stir again until evenly distributed.
  4. Package the product.

2. Adding Boiled Ginseng Water

Adding boiled ginseng water directly to this silicone-based formula is not recommended. Silicones like Cyclopentasiloxane and Dimethicone are not soluble in water. Adding water without a proper emulsifier system designed for silicone/water emulsions will cause the mixture to separate.

If you wish to incorporate a water-based ingredient like ginseng water, you would need to significantly change the formulation to create an emulsion (like a lotion or cream) using suitable emulsifiers that can bind the silicone phase with the water phase. This would result in a different product texture and feel than a typical silicone serum.
