Sebum Resistant (SR)-Treated Pigments; INCI name: Trimethylsiloxysilicate
Trimethylsiloxysilicate (SR)-treated pigments and fillers provide superior adhesion to skin and hair. SR pigments are the best candidates to be used in long-wearing and water-resistant makeup. They are hydrophobic yet are not overly sensitive to oils including sebum. For more detailed technical information, see our article in Expression Cosmétique!
SR Treatment Benefits:
- Superior skin adhesion
- Water repellency
- Low oil absorption
- Provides long wear
- Higher loading capacity
Recommended Uses:
- Long-wearing lipsticks
- Long-wearing foundations
- Long-wearing eyeshadows
- Long-wearing eyeliners
