Question

I am formulating an O/W emulsion serum for facial application. I need ingredient recommendations to achieve a distinct shiny, glowy finish upon application. Silicone ingredients are acceptable.

Could you recommend suitable ingredients, such as specific silicones or esters with a high Refractive Index (RI), and provide usage guidelines to achieve this high-gloss effect?

Answer

The key to formulating an O/W emulsion serum with a shiny, glowy finish is to incorporate ingredients with a high refractive index (RI) into the oil phase. These ingredients create a smooth, light-reflecting film on the skin.

Here are the recommended ingredients, categorized by function:

1. High-Refractive Index (RI) Shine Agents (Silicones)

These ingredients provide the highest level of non-greasy, reflective shine and excellent slip.

Product ID Product Name Key Benefit Usage Guideline
35411 Silicone Shine Ultra170™ Ultra-high shine, medium viscosity, excellent film formation. 1-10% in the oil phase.
924 Silicone Shine Max15™ Super shine, very low viscosity, lightweight feel. Ideal for a thin serum. 1-5% in the oil phase.
  • Tip: You can use a blend of both. Silicone Shine Max15™ provides a lighter feel, while Silicone Shine Ultra170™ offers more lasting shine and body.

2. High-Gloss Esters (Non-Silicone Glow)

These esters enhance the natural "wet look" glow and provide a cushiony, comfortable feel on the skin.

7510 LipidSoft™ Shine Specifically designed to provide a high-gloss, non-sticky finish, acting as a natural alternative to some silicones. 3-15% in the oil phase, replacing traditional oils.
7975 Isocetyl Stearoyl Stearate High-gloss ester with excellent cushion and emolliency, contributing to a healthy, dewy look. 3-10% in the oil phase.

3. Texture and Slip Enhancer

This ingredient improves the spreadability and luxurious feel of the serum, ensuring the shine agents are distributed evenly.

201 Silicone Gel (Ultra Clear, Super Silky) Provides a silky, non-tacky feel and helps suspend other ingredients. 1-5% in the oil phase.

Formulation Guidelines for a Glowy O/W Serum

  1. Oil Phase Composition: Aim for an oil phase that is 10-20% of the total formula. The majority of this phase should be the high-RI ingredients (Silicone Shine, LipidSoft Shine).
  2. Emulsification: Use a robust O/W emulsifier suitable for high oil loads and silicone content (e.g., a non-ionic PEG-free emulsifier or a blend of emulsifiers).
  3. Application: The combination of high-RI silicones and esters will ensure the serum leaves a noticeable, light-reflecting film that gives the desired "glowy" finish. The silicones prevent the esters from feeling too heavy or greasy.
