Applications of Solvay Tixosil 365 Precipitated Silica (High Absorption) in Industrial Manufacturing

As the manufacturer of Solvay Tixosil 365, we support global industrial leaders by providing a high-absorption precipitated silica optimized for critical performance in demanding downstream applications. The following sections outline its established role across key industries, with detailed, application-specific integration including regulatory compliance, formulation methods, process stages, and finished product types.

1. Toothpaste Abrasives and Rheology Control

Tixosil 365 provides high absorption and tailored particle morphology, making it an industry standard for achieving controlled abrasivity and thickening in silica-based toothpaste formulations. Its structure directly supports homogeneous dispersion and paste viscosity modification, while also improving texture and preventing syneresis during shelf life. We collaborate with global oral care producers for both conventional and specialty dentifrice lines.

Industry compliance standards

• ISO 11609 (Dentistry — Toothpastes — Requirements, test methods and marking)
• FDA 21 CFR 172.480 (U.S. Food Additive: silica for toothpaste)
• EU Regulation (EC) No 1223/2009 (Cosmetic Products Regulation)
• Chinese GB/T 8372-2017 (National standard for toothpaste)

Typical usage ratio

• 10–25% by weight of toothpaste batch; dosage varies depending on required RDA (Relative Dentin Abrasivity) and rheological balance for specific paste and gel formats.

Downstream process integration

• Dispersed in the paste aqueous phase after sweeteners and before surfactants, Tixosil 365 enables stable slurry formation and uniform distribution before final homogenization and tube filling.

Final product types

• Clear gels, opaque pastes, whitening toothpastes, kids’ toothpastes, herbal and medicated toothpaste lines.

2. Rubber Reinforcement for Footwear and Tire Compounds

In elastomer compounding, Tixosil 365 serves as an active reinforcing filler, enhancing tensile strength, modulus, and abrasion resistance without compromising dynamic flexibility. High absorption properties facilitate efficient coupling with silane agents and promote compatibility with low-oil and high-performance formulations, used by leading tire and technical rubber goods manufacturers.

Industry compliance standards

• ISO 9001:2015 (Quality management systems for production)
• REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) compliance for EU exports
• EU Directive 2000/53/EC (End-of-Life Vehicles, for material content)
• ASTM D2000 (Rubber Products in Automotive Applications)

Typical usage ratio

• 15–45 phr (parts per hundred rubber); the specific dosage is tailored according to the hardness, abrasion rating, and wet grip requirements of end products.

Downstream process integration

• Introduced during internal mixing (Banbury or kneader) with other fillers and curatives, promoting early wetting and silane coupling. Followed by extrusion, calendaring, and vulcanization.

Final product types

• Passenger car tires, truck and bus tires, high-durability shoe soles, conveyor and transmission belts, technical gaskets, and anti-vibration rubber parts.

3. Industrial Powder Coatings and Matting Agents

Tixosil 365’s fine particle size and high absorption give formulators the ability to control gloss, scratch resistance, and matting in powder coatings. By managing pigment orientation and absorbing excessive binder, it supports thin-film performance in architectural, automotive, and appliance coatings, including impact on anti-caking during storage.

Industry compliance standards

• EN ISO 12944 (Paints and varnishes — Corrosion protection of steel structures by protective paint systems)
• REACH Annex XVII (Chemical restrictions)
• RoHS Directive 2011/65/EU (Restriction of hazardous substances in electrical and electronic equipment)
• Qualicoat and GSB (Global standards for architectural coatings)

Typical usage ratio

• 0.5–3.0% by weight; fine-tuned according to the target gloss level and matting requirements for semi-matte and full matte systems.

Downstream process integration

• Dry-blended with pigments, resins, and additives prior to extrusion. Tixosil 365’s high absorptivity allows precise incorporation of liquid and low-volatility matting components before micronization and electrostatic spray application.

Final product types

• Architectural aluminum profiles, appliance housings, automotive refinishing powders, outdoor metal furniture, steel fencing, and specialty industrial coatings.

4. Animal Feed Additive for Flow Improvement and Anti-caking

Tixosil 365 improves flowability and prevents clumping in mineral/vitamin premixes and compound feeds. The high absorption capacity not only minimizes lump formation during production and transport but also stabilizes sensitive micronutrients by surface adsorption, trusted by global animal nutrition and premix producers.

Industry compliance standards

• European Feed Additives Register (EU Regulation (EC) No 1831/2003)
• FDA 21 CFR 573.940 (Silicon Dioxide as an animal feed additive in the U.S.)
• FAMI-QS (Feed Additive and Premixtures Quality System Certification)
• GMP+ Standard (Good Manufacturing Practice for feed industry)

Typical usage ratio

• 0.5–2.0% by weight in premixtures; adjusted for moisture level, fat content, and powder grain size of the feed matrix.

Downstream process integration

• Mixed at the powder blending stage prior to liquid addition, Tixosil 365 supports microingredient homogenization, followed by pelletizing or bagging in downstream feed operations.

Final product types

• Vitamin and mineral premixes, amino acid blends, compound poultry and livestock feeds, fish feed powders, and stabilized microingredient supplements.

5. Carrier and Free-Flow Agent in Agrochemical Water-Dispersible Granules

Tixosil 365’s high-porosity structure allows for efficient absorption of liquid active ingredients, enabling the production of water-dispersible granules (WDG) with rapid dissolution rates. This property controls dusting and eases handling during high-volume agrochemical packaging and application, critical for large-scale crop protection manufacturing.

Industry compliance standards

• FAO/WHO Specifications and Evaluations for Agricultural Pesticides
• EPA 40 CFR Part 180 (U.S. pesticide inert ingredients regulation)
• ISO 1750 (Pesticides and other agrochemicals nomenclature)
• Good Laboratory Practice (GLP) for agrochemical formulation testing

Typical usage ratio

• 3–10% in water-dispersible granule formulations; the effective amount depends on the oil load, granule disintegration target, and the type of active being carried.

Downstream process integration

• Used at the premix step to adsorb liquid or highly concentrated actives, Tixosil 365 is then granulated with dispersants and binders before drying and sieving to final size specification.

Final product types

• Herbicide WDG, fungicide granules, insecticide water-soluble packets, seed treatment granules.

6. Free-Flow and Anti-Caking Agent in Food Powder Processing

Our high-absorption precipitated silica is accepted as a processing aid for moisture regulation and clumping prevention in food powders. Leading global producers rely on its ability to keep hygroscopic ingredients—such as powders, spices, and flavor concentrates—free-flowing and stable throughout storage and retail distribution.

Industry compliance standards

• FDA 21 CFR 172.480 (Silicon Dioxide food additive in U.S.)
• EU Regulation (EC) 1333/2008 (Food additives, E551—Silicon Dioxide)
• Codex Alimentarius (JECFA, Silicon Dioxide specs)
• GB 2760–2014 (Chinese National Food Safety Standard for Food Additives)

Typical usage ratio

• 0.5–2.0% in food powders by weight, with adjustments based on ingredient oiliness, humidity, and free-flow criticality for dry-mix blends.

Downstream process integration

• Dosed at the final blend stage to cover each granule and avoid aggregation, Tixosil 365 enables efficient packaging and improves product shelf life prior to retail packing and shipment.

Final product types

• Spice blends, soup powders, instant drink mixes, nutritional premixes, powdered flavors and colorants, ready-to-eat cereal and baking powder formulations.
