2. Demand breakdown by sector: seven industries driving massive consumption
The strength of the South American market lies in its diversification: it does not depend on a single customer sector, but has multiple sources of demand that complement each other and reduce market volatility. Below, each of the key industries is analyzed in detail.
2.1 Personal care and cosmetics: the sector with the highest consumption of specialty silicon dioxide
The personal care sector is one of the most solid drivers of silicon dioxide demand in South America, especially in Brazil, which has the second-largest beauty and personal care industry in the world by volume of units sold.
Application in toothpastes: the highest-volume segment
Dental-grade silicon dioxide is the most widely used cleaning and thickening agent in toothpaste formulations, progressively replacing calcium carbonate in mid-range and high-end products. In South America, the consumption of silicon dioxide for dental use exceeds 65,000 tons per year, of which more than 42,000 tons correspond exclusively to Brazil.
The demand is supported by the presence of the sector's leading multinationals: Colgate-Palmolive, Unilever, Procter & Gamble, Henkel and GSK have production plants in Brazil, Argentina and Chile, and supply the entire region from these facilities. In addition, the boom in local brands and in dental whitening products, toothpastes for sensitive teeth and natural formulas has driven demand for special grades of silicon dioxide with perfectly controlled particle size and abrasivity parameters.
Application in cosmetics and skin care: growth of the premium range
In the cosmetics segment, pyrogenic silicon dioxide is used as a matting, thickening, anti-caking, and texturizing agent in creams, lotions, makeup, body scrubs, and sun protection products. Over the past five years, the consumption of cosmetic-grade silicon dioxide in South America has grown at an annual rate of 7.9%, well above the regional average, driven by increased per capita spending on beauty, the growing popularity of skincare routines, and the entry of high-end international brands into the market.
Brazil leads this segment with more than 70% of regional consumption, followed by Argentina and Chile, where the premium cosmetics market has recorded especially notable growth in recent years.
2.2 Food and beverage industry: stable demand for food grades
The food and beverage industry is the second-largest sector by consumption volume of food-grade silicon dioxide, with more than 58,000 tons annually across South America. Silicon dioxide approved for food contact is used mainly as an anticaking agent in food powders, as a clarifier in beers and beverages, and as an adsorbent in the refining of edible oils and fats.
Anticaking agents for powdered products: the most widespread use
In products such as milk powder, cheese powder, whey, seasonings, powdered sugar, specialty flours, and nutritional supplements, silicon dioxide prevents the formation of lumps and improves the flowability of powders during processing, packaging, and storage. With the growth of the processed food and sports supplement industries in the region, demand for this type of silicon dioxide has maintained steady growth of 4.5% per year.
Brazil, as South America's largest food producer and one of the world's leading exporters of agri-food products, accounts for more than 60% of this consumption. Argentina, in turn, records significant demand derived from its powerful dairy and processed meat industry.
Clarification of beers and beverages
Another relevant application is the use of silica gel as a clarifying agent in beer production, where it removes protein compounds that cause haze and improves the beverage's stability throughout its shelf life. South America has a large brewing industry: Brazil is the world's third-largest beer producer, and countries such as Colombia, Argentina, and Peru also have highly developed domestic markets.
The expansion of craft breweries across the region has also contributed to increasing demand for food-grade silica gel, as these brands seek high-quality products to ensure the clarity and stability of their brews.
2.3 Pharmaceutical and healthcare sector: growing demand for high-purity grades
The South American pharmaceutical sector has experienced sustained growth over the past decade, driven by increased access to healthcare, the expansion of the generic drug market, and greater regulation regarding quality excipients. In this context, pharmaceutical-grade silicon dioxide has become an essential excipient, used as a glidant, anti-caking agent, and carrier in tablets, capsules, and medicinal powders.
Annual consumption of pharmaceutical silicon dioxide in the region is around 12,000 tons, with an annual growth rate of 6.8%, far higher than that of the general market. Brazil accounts for more than 65% of this consumption, as it has the most developed pharmaceutical industry in Latin America, with plants from multinational and national laboratories that supply both the domestic market and exports to other South American countries.
In addition, the boom in the food supplement and natural health products market has generated additional demand for food-pharmaceutical grade silicon dioxide, especially in countries such as Chile, Argentina, and Colombia, where awareness of health and wellness has increased significantly.
A key characteristic of this segment is the high requirement for regulatory compliance: products must comply with standards such as the United States Pharmacopeia (USP), the European Pharmacopoeia (EP), and the local standards of each country, which raises the barrier to entry and causes demand to concentrate among suppliers with internationally recognized certifications.
2.4 Plastics and packaging industry: the fastest growth engine in recent years
The plastics and packaging industry is undoubtedly the sector that has driven the growth of silicon dioxide demand in South America the most over the past five years, with a compound annual growth rate of 7.2%. Silicon dioxide is used in this sector mainly as an anti-blocking agent (opener) in plastic films, as a matting agent in coatings and plastics, and as reinforcement in composite materials.
Anti-blocking agent for packaging films: the highest-volume segment
The most in-demand application is anti-blocking in polyethylene (PE), polypropylene (PP) and BOPP films, used in food packaging, industrial products and consumer goods. Silicon dioxide forms micro-protrusions on the film surface, preventing the layers from adhering to each other during winding and facilitating unwinding on industrial filling lines.
The e-commerce boom in South America has driven up demand for flexible packaging, as more and more products are sold over the internet and require durable, high-quality packaging. In addition, the growth of the processed food and beverage industry has increased the need for packaging films with special properties, such as high transparency, temperature resistance and guaranteed food safety.
Brazil has an important industry for plastic films and anti-blocking masterbatches, but most companies depend on imports of high-quality silicon dioxide for their formulations, especially for high-end products such as high-transparency films and medical-use packaging.
Other applications in plastics
In addition to anti-blocking agents, silicon dioxide is used as a matting agent in PVC profiles, plastic parts for furniture and automation, and as reinforcement in rubber and plastic compounds. With the growing demand for plastic materials with matte finishes and improved mechanical properties, this segment also shows steady positive growth.
An emerging niche with great potential is that of biodegradable and bio-based plastics, where silicon dioxide is used as an additive to improve the processability and mechanical properties of these materials. As the region adopts stricter standards on single-use plastics, demand for silicon dioxide for this type of application is expected to increase significantly in the coming years.
2.5 Tire and rubber industry: demand for highly dispersible precipitated silicon dioxide
The tire industry is one of the historical consumers of highly dispersible precipitated silicon dioxide (HDS), used as a reinforcing filler in rubber compounds to reduce rolling resistance, improve wet grip and increase tire durability.
South America has a well-established automotive and tire industry: Brazil is the largest producer of vehicles and tires in the region, with plants of the main global manufacturers such as Bridgestone, Michelin, Goodyear, Pirelli and Continental. Argentina and Chile also have tire production and significant demand for the replacement market, which accounts for most of the total volume.
Annual consumption of silicon dioxide for tires in the region is around 72 thousand tons, accounting for almost 20% of total consumption. The transition to eco-friendly low-rolling-resistance tires, driven by energy efficiency standards and demand from consumers more conscious of the environment, has caused the proportion of silicon dioxide in tire formulations to increase progressively, generating sustained demand growth.
In addition to the tire sector, silicon dioxide is also used in other rubber products such as hoses, belts, seals, and footwear soles, sectors that also show stable demand throughout the region.
2.6 Paint and coatings industry: driven by construction and industry
The paint and coatings industry is another important consumer of silicon dioxide, with annual consumption in South America of approximately 45,000 tons. Fumed and precipitated matting silicon dioxide is used as a rheology agent, anti-settling agent, and matting agent in architectural, industrial, wood, and automotive coatings, as well as in flexographic and offset printing inks.
Construction and infrastructure momentum
In recent years, the recovery of the construction sector in countries such as Brazil, Chile, and Colombia has significantly boosted demand for architectural paints, and consequently for silicon dioxide. Social housing programs, investment in road infrastructure, and the renovation of commercial buildings have generated a greater need for coatings of all types and ranges.
Growth of industrial and high-performance paints
On the other hand, the development of the South American manufacturing industry has increased demand for high-performance industrial paints, which require high-quality additives such as fumed silicon dioxide to control rheology and improve the properties of the paint film.
The printing inks segment also contributes significantly to demand, especially with the growth of the packaging industry and the printing of high-quality labels and flexible packaging.
2.7 Agriculture and animal nutrition: a high-volume market with growth potential
As the world's leading region in agricultural and livestock production, South America has a very significant demand for food-grade silicon dioxide for use in animal nutrition and agricultural inputs.
Animal nutrition: anti-caking agents for feed and supplements
In the production of feed for cattle, poultry, swine, and aquaculture, silicon dioxide is used as an anti-caking agent to improve the flowability of powdered and granulated feed, prevent clumping during storage, and ensure a homogeneous distribution of nutritional additives.
Brazil, Argentina, Uruguay, and Paraguay are among the largest grain and meat producers in the world, with a huge animal nutrition industry. Annual consumption of silicon dioxide for feed in the region exceeds 38,000 tons, and it is expected to continue growing as animal protein production increases to supply both the domestic market and global exports.
Agricultural inputs: carriers and additives for agrochemical formulations
In the agrochemical sector, silicon dioxide is used as a carrier and anti-caking agent in powder and granular formulations of herbicides, fungicides, and insecticides. South America is one of the largest agrochemical markets in the world, so this application represents a significant demand volume, with growth potential as more efficient and higher-quality formulations are adopted.
3. The central role of Brazil: why it is the most attractive market in South America
Brazil is not only the largest country in South America in terms of size and population, but it also concentrates the region's most complete and diversified industrial base, which makes it the undisputed engine of silicon dioxide demand.
3.1 Diversified industrial base and multisectoral demand
Unlike other South American countries that depend on one or two main sectors, Brazil has developed industries in all key segments for silicon dioxide: personal care, food, pharmaceuticals, plastics, tires, paints, and agriculture. This diversification makes the Brazilian market more resilient to economic crises and sustains steady long-term growth.
3.2 Large population and massive consumer market
With more than 215 million inhabitants, Brazil has the largest consumer market in Latin America. The growth of the middle class over the past two decades has generated sustained growth in the consumption of final consumer goods, from toothpaste and cosmetics to processed foods and packaged products, which translates directly into greater demand for chemical raw materials such as silicon dioxide.
3.3 Insufficient local production capacity and high dependence on imports
Despite its large consumption volume, Brazil has a very limited local production capacity for silicon dioxide, especially in mid-range and high-end grades. Most local production focuses on standard grades for basic applications, while high-purity, controlled-particle-size, and special-grade products (pyrogenic, dental, pharmaceutical) depend to a large extent on imports.
The main suppliers of imported silicon dioxide in Brazil are China, the United States, and European countries. In recent years, Chinese products have gained a growing market share thanks to their good quality-price ratio, constant quality improvement, and the availability of international certifications such as USP, EP, and official food certifications.
3.4 Long-term growth potential
Despite its current size, the Brazilian silicon dioxide market still has ample room for growth. Per capita consumption of silicon dioxide in Brazil is still lower than in developed countries such as the United States, Germany, or Japan, which indicates that as income levels and industrialization increase, demand will continue to expand progressively.
In addition, emerging sectors such as solar energy (with the use of silicon dioxide in encapsulant films for photovoltaic panels), lithium batteries, and advanced materials will generate very relevant new sources of demand in the coming years.
4. Structural factors driving the sustained growth of demand
The steady growth in demand for silicon dioxide in Brazil and South America is not accidental, but is supported by structural factors that guarantee the long-term expansion of the market.
4.1 Demographic expansion and increased purchasing power
South America has more than 430 million inhabitants, a young and growing population, with an expanding middle class that increasingly demands higher-quality products. As per capita income rises, consumption of personal care products, processed foods, durable goods, and services grows, which translates directly into greater demand for chemical raw materials.
4.2 Progressive industrialization and development of local supply chains
In recent decades, South America has experienced a process of progressive industrialization, with the development of local supply chains in sectors such as packaging, cosmetics, food, and pharmaceuticals. More and more multinational companies are setting up production plants in the region to supply the local market and avoid the high tariffs and logistics costs of importing finished products.
This trend increases demand for chemical raw materials such as silicon dioxide, as local plants need to source inputs for their production. Unlike finished products, chemical inputs have lower tariffs in most South American countries, which favors the import of quality raw materials.
4.3 Increasing regulatory requirements and replacement of low-quality products
Regulatory bodies in South American countries have been tightening standards related to food safety, pharmaceutical quality, cosmetic safety, and the properties of packaging materials. This increased demand is causing companies to progressively abandon low-quality additives without certifications and opt for high-quality silicon dioxide with internationally recognized certifications.
For example, in the food sector, the MERCOSUL standard on food additives establishes strict purity and safety requirements for silicon dioxide, which raises the entry barrier for low-quality products. In the pharmaceutical sector, the adoption of good manufacturing practice (GMP) standards and the requirement for compliance with USP and EP have driven demand for high-end products.
4.4 Emergence of emerging sectors with new demand potential
In addition to traditional sectors, new applications of silicon dioxide are emerging that will generate significant demand volumes in the coming years:
