Feedback on Serum Formulation

Hello, thank you for sharing your serum formulation aimed at a light, easily absorbed texture.

Based on the ingredients and percentages you've provided, this formulation seems well-designed to achieve a light and easily absorbed serum. The combination of water-soluble actives, DMI as a penetration enhancer, and Cyclopentasiloxane for sensory feel, along with Satin Cream Maker as an emulsifier, should help create a serum with the characteristics you desire.

Regarding your additional questions:

1. Mixing Satin Cream Maker manually: While it might be possible to mix Satin Cream Maker manually, using a blender or homogenizer is generally recommended. Emulsifiers like Satin Cream Maker require sufficient shear to properly form a stable emulsion and achieve the desired smooth, silky texture. Manual mixing may result in a less homogeneous or less stable product compared to using a mechanical mixer.
2. Omitting Silicone (Cyclopentasiloxane): Cyclopentasiloxane plays a significant role in providing the light, non-greasy, and easily spreadable feel you are looking for. It helps to reduce tackiness and improves the slip of the serum on the skin, contributing to quick absorption feel. If you remove Cyclopentasiloxane from this specific formula without replacing it with an alternative ingredient that provides similar sensory benefits (like certain light esters or emollients), the serum will likely feel heavier, potentially stickier, and less easy to spread, which is contrary to your goal of a light, non-heavy serum. Therefore, for this specific formulation aiming for a light feel, Cyclopentasiloxane is quite important.

Overall, your proposed formulation appears suitable for creating a light, easily absorbed serum, provided the ingredients are mixed correctly, especially the emulsifier.
