Product Description

Manta A203B is a hydrophobic film-forming blend, consisting of solid Trimethylsiloxysilicate (MQ Resin) fully dispersed in a Dimethicone carrier.

Designed to overcome the stiffness and cracking often associated with traditional resin solutions, Manta A203B creates a flexible, breathable, and coherent matrix on the skin. It acts as a powerful fixative that locks pigments and active ingredients in place, providing exceptional transfer resistance (rub-off resistance) while maintaining a comfortable, non-tightening sensory profile. Its specific viscosity profile makes it an ideal rheology modifier for stabilizing BB cushions and liquid foundations.

Excellent Film-Forming: Creates a durable mesh-like film that resists water and rubbing (Waterproof & Rub-resistance);
Sensory Profile: Provides a unique silky and smooth feel; soft and non-greasy;
Adhesion: Enhances the adherence of pigments and powders to the skin (Long-lasting);
Thickening & Gloss: Helps thicken cushion formulations and increases gloss/shine;
Breathable: The film is permeable to air, preventing a “suffocating” feel on the skin.

Application Details

Phase of Addition: Add to the Oil Phase.
Processing: Mix well with other oils or silicones. It can be heated (heat stable).
Skin Care / BB Creams: 1.0% – 5.0% (For feel and light film);
Color Cosmetics (Lipstick/Foundation): 5.0% – 20.0% (For strong film-forming and transfer resistance).
Incorporation: Manta A203B is an oil-phase ingredient. It can be added to the silicone or oil phase of the formulation.
Compatibility: Miscible with other silicones (Cyclics, Dimethicones, Phenyl Trimethicone) and Isododecane. Limited compatibility with high-polarity plant oils (may require a compatibilizer like Caprylyl Methicone).
Processing: Stable at elevated temperatures. Can be processed hot or cold.
BB Cushions & Liquid Foundations: The key ingredient for transfer-proof foundations that still look moist and glowing. It stabilizes the emulsion and prevents pigment settling.
Liquid Lipsticks: Provides the anchor for long-wear lip color that feels moisturizing rather than drying.
Sun Care: Significantly boosts SPF retention (water resistance) during swimming or sweating.
Eyeliner & Mascara: Ensures smudge-proof performance and intense color payoff.
