Common Name(s): Isopropyl titanium triisostearate/triethoxycaprylylsilane crosspolymer,ti-silane crosspolymer pigment treatment

DESCRIPTION

What It Does: Improves how pigments spread and stick on skin, and helps makeup resist water and sweat.

Why It's Used: Selected for treating mineral pigment surfaces (tio2, zno, micas) to improve their dispersion in formulas and enhance wear properties of color cosmetics.

How It Works: Ti-o-si crosspolymer network forms a hydrophobic organic coating on inorganic pigment surfaces; isostearate chains increase compatibility with oil phases; silane groups bond covalently to pigment surfaces.

Typically Found In: Foundations,pressed powders,long-wear makeup,sunscreens,color cosmetics

TECHNICAL DETAILS

Primary Category: Functional ingredient – adhesion promoting

Secondary Functions: Pigment dispersing,emollient,skin conditioning

Application Areas:

Typical Concentration Range: As surface treatment on pigments (typically 0.1%–2% of pigment weight)

SOURCING & ETHICS

Vegan Status: Yes

Halal Status: Yes

Source Notes: Synthetic; titanium/silane hybrid; applied as surface treatment to mineral pigments.

SKIN COMPATIBILITY

Irritancy Rating: 1/5 – very low

Comedogenicity Rating: 1/5 – low

Sensitivity Concerns: Generally inert surface treatment; safety profile driven by carrier pigment. non-irritating.

Safe for Sensitive Skin: Yes

SAFETY & COMPATIBILITY

Safety Profile: Good safety profile. ewg score: 1–2.

Works Well With: Mineral pigments (tio2/zno/micas),silicone-based bases,wax formulations

Avoid Combining With: Incompatible with strong bases (hydrolyzes silane bonds)

SCIENTIFIC NOTE

Dual ti-o and si-o bonding creates a bifunctional surface coating on mineral pigments; the organic isostearate tail orients outward, making the hydrophilic mineral surface lipophilic (oil-dispersible) while the silane ensures strong covalent anchoring.
