Common Name(s): Cobalt titanium oxide,cobalt titanium oxide,mineral extract,trace mineral cosmetic active

CAS Number: N/a

DESCRIPTION

What It Does: Provides trace mineral ions and mineral-specific compounds for skin conditioning, astringency from clay minerals, or optical effects from metal oxide pigments.

Why It's Used: Mineral extracts provide authentic geological origin narratives for luxury cosmetics — trace mineral delivery addressing the skin's mineral nutritional environment from earth-source chemistry.

How It Works: Clay minerals (silicate sheets): exchangeable cations (ca²⁺, mg²⁺, k⁺) adsorb/desorb providing mineral buffering and cation exchange conditioning. metal oxides (cobalt, titanium): uv-scattering and pigment optical effects. calcite (caco₃): mild buffering, slip, and gentle exfoliation from crystal microstructure.

Typically Found In: Premium skin care,mineral cosmetics

SCIENTIFIC NOTE

Clay mineral cosmetic grade: cosmetic-grade clays require characterisation of heavy metal content (pb, as, hg) — natural clay deposits often contain trace heavy metals requiring analytical verification of safety below regulatory limits.
