Improving Liquid Lipstick for Matte Finish and Longevity

Hello! I understand the issue you're experiencing with your silicone-based liquid lipstick that is thick but not matte and wipes off easily. You can improve this by adding ingredients from two main groups:

1. Film Formers

These ingredients create a thin film layer on the lips after the volatile silicones evaporate. This film helps the lipstick adhere better, making it long-lasting, non-transfer, and waterproof.

• Examples of silicone film formers include Trimethylsiloxysilicate, which comes in various forms. There are powder types like Silicone Film (Powder, Hard Film, Comfort-Wear) that provide a medium-hard film, or liquid types dissolved in silicones like Silicone Film (Very Long-Wear, Hard, Cyclopentasiloxane Base) for a hard, very long-lasting film, or Silicone Film (Soft Film, Low Viscosity, Cyclopentasiloxane Base) for a soft, long-lasting film.
• Additionally, Silicone Film (Medium-Wear, Soft) is an Acrylate silicone film suitable for lip products that helps with longevity and provides a matte texture.
• Typical usage rates for silicone film formers are usually between 5-30%, depending on the desired level of longevity.

2. Matte Agents

These are fine powders that absorb oil and reduce shine, helping to achieve a matte finish.

• Examples include MatteSilica 5™ (5 Micron), a porous silica powder that absorbs oil well and gives a powdery feel, ideal for mattifying lipsticks.
• Another option is Sericite Powder (CompactPro™, Matte, Dimethicone Coated), a coated Sericite powder that provides a matte finish and a smooth, soft feel.
• Usage rates vary; you can generally start from 1-10% and adjust as needed to get the desired matte level.

Additional Tips

• Volatile silicone bases like Cyclopentasiloxane or Dimethicone (Very Light/2, Volatile) are crucial for helping the lipstick dry quickly and leave the film and matte powders on the lips. If your current base doesn't contain them, consider adding them.
• When modifying your formula, it's best to experiment with small batches. Gradually add the film formers and matte agents little by little, testing the results until you achieve the desired texture and matte finish.
• Mix the film formers and matte agents into the silicone or oil phase of your formula first.
