Minerals Technologies Consumer & Specialties division overview

The Consumer & Specialties segment of Minerals Technologies Inc. (NYSE: MTX) develops and manufactures functional mineral additives and performance materials worldwide.

Core business units comprise Household & Personal Care (high-swelling sodium and calcium bentonites) and Specialty Minerals Inc. (precipitated and ground calcium carbonates, micro-talc).

Operating facilities across North America, Europe, and Asia utilize advanced crystal engineering and surface chemistry to tailor mineral properties for paper, polymers, sealants, cosmetics, and food.

Sodium bentonite for pet care and detergents

Household & Personal Care is the foremost global miner and processor of premium sodium bentonite from deposits in Wyoming's Black Hills geological formation.

In pet care, this high-swelling montmorillonite forms dense, agglomerated clumps instantly upon wetting, providing clean scooping without disintegrating into the litter tray.

High cation exchange capacity exceeding 85 to 105 meq/100g ensures superior odor control by binding ammonia and volatile amines through chemisorption without heavy synthetic perfumes.

Purified smectites BENTOLITE and GELWHITE for cosmetics

Specialty smectite clays BENTOLITE and GELWHITE are purified through intensive hydrocyclone classification and microbiological sterilization to eliminate all crystalline silica grit.

In cosmetic creams, lotions, and oral care pastes, these colloidal magnesium aluminum silicates stabilize oil-in-water and water-in-oil emulsions against syneresis and heat-induced breakdown.

Suspensions display pseudoplastic and thixotropic rheology: shear forces reduce viscosity during spreading for a silky skin feel, while structure recovers immediately at rest to eliminate dripping.

Activated bleaching earths for vegetable oils and biofuels

Adsorbent technologies produce acid-activated montmorillonite bleaching earths engineered for deep purification, decolorization, and degumming of triglyceride oils.

Surface areas up to 350 m2/g effectively capture chlorophyll, carotenoids, heavy metal traces, and soap residues from sunflower, rapeseed, soybean, palm oils, and animal tallows.

Balanced particle sizing delivers rapid filtration throughput across leaf filters while keeping neutral oil retention in spent filter cakes below 22 to 25 percent by weight.

Precipitated calcium carbonate PCC for papermaking

Specialty Minerals synthesizes precipitated calcium carbonate (PCC) via controlled reaction of hydrated lime slurry with carbon dioxide gas, often through on-site satellite plants.

Scalenohedral crystal aggregates (ALBACAR series) provide high optical light scattering and ISO brightness exceeding 96 percent, boosting paper opacity at lighter basis weights.

Prismatic morphologies (ALBAFIL) maximize tensile strength and bulk, enabling papermakers to substitute up to 20 to 25 percent of expensive chemical wood pulp with mineral filler.

Ultrafine surface-treated PCC for sealants and adhesives

Ultrafine PCC grades ULTRA-PFLEX and CALOFORT feature primary nano-crystals of 40 to 80 nanometers coated with a uniform monolayer of calcium stearate for complete hydrophobization.

In polyurethane, MS polymer, and silicone sealants, the nanoparticles establish a thixotropic colloidal network that imparts high yield stress, eliminating slump in vertical expansion joints.

The surface-modified crystals disperse homogeneously into plasticizers without agglomerating, enhancing tear strength, tensile modulus, and elongation performance.

Barretts Minerals micro-talc and antiblocking additives

Barretts Minerals quarries high-purity platy talc in Montana, producing MICRO-TALC and OPTIBLOC antiblocking additives with high lamellar aspect ratios.

In automotive TPO compounding, micro-talc reinforces polypropylene matrices, raising heat deflection temperatures (HDT) and flexural modulus while maintaining low-temperature impact ductility.

OPTIBLOC antiblocking grades match polyolefin refractive indices, creating controlled micro-roughness on blown and cast films to prevent roll blocking without causing optical haze.

Natural ground calcium carbonate GCC grade VICRON

Specialty Minerals produces high-whiteness natural ground calcium carbonate under the registered VICRON trademark from selected microcrystalline calcite deposits.

Standard cuts feature controlled median sizes d50 from 1.5 to 12 microns with calcium carbonate purity above 98.5 percent and minimal abrasive quartz impurities.

In architectural coatings, powder coatings, and dry mortars, VICRON delivers high opacity, low oil absorption (14 to 18 g/100g), and excellent chemical weatherability.

Pharmaceutical and food-grade calcium CALESSENCE

Synthesized under strict cGMP protocols, CALESSENCE and VICALITY precipitated calcium carbonates comply with USP, European Pharmacopoeia (EP), and Food Chemicals Codex (FCC) monographs.

Heavy metal impurities are stringently controlled: lead remains below 0.25 ppm and arsenic below 0.5 ppm, supporting safety in direct tableting and dietary supplements.

Tailored bulk densities and compressibility characteristics allow rapid direct compression without capping, ensuring uniform tablet dissolution rates.
