Special Silicas for the Oral Care Industry
Glassven has developed advanced technologies to provide its customers with high performance Precipitated Silicas with a wide range of structure and morphology ideally suited to meet the most challenging needs.
DENTSIL® products line satisfy the Oral Care Industry needs,which have an excellent fluoride compatibility, independently of the fluoride source, such as: Sodium Fluoride (NaF) or Sodium Monofluorophosphate (MFP).
Precipitated Silica is a very useful material in toothpaste formulations to help mechanical elimination of dental plaque and impart rheological properties.
Our dental Silicas are considered safe and effective in all dentifrice applications because they have been designed with standard RDA values in order to protect the tooth dentin.
Abrasives
Product | Abrasivity | Thickening |
DENTSIL®DS-60 | Medium | low |
DENTSIL®DS-100 | Good | low |
DENTSIL®DS-160 | Very Good | very low |
Thickening
Product | Abrasivity | Thickening |
DENTSIL®DS-230 | very high | Good |
Our expertise in manufacturing Precipitated Silicas enables us to precisely control the size and shape of the particles. These parameters directly impact the abrasive properties of the product, considering that abrasion is a major concern for toothpaste manufacturers.
Unlike calcium-based polishing agents, DENTSIL Silicas are compatible with all active ingredients and therapeutic agents such as sodium fluoride. Furthermore, they can be used in transparent and colored gels.
DENTSIL®DS-60
It is an unique Precipitated Silica used as Mild Abrasive Agent, which combines good abrasion level and very high cleaning power due to its standard RDA and high PCR value.
It provides excellent transparency in high clarity toothpastes. It is highly recommended in formulations for children and therapeutic toothpastes (for sensitive teeth and gums).
DENTSIL®DS-100
It is a Precipitated Silica with high abrasive power and high cleaning properties. Its RDA and high PCR values make it suitable for those toothpaste formulations that demand a higher polishing level.
It is recommended in opaque and striped formulas.
DENTSIL®DS-160
It is a Precipitated Silica that has been especially designed to provide higher abrasion and cleaning properties due to its superior RDA and PCR values. It is ideal for whitening, anti-plaque and smokers pastes.
Thickening Agent
Thickening agents are used in toothpaste formulations to avoid viscosity variations, which are mainly caused when detergents and aromatic oils are added into the formula.
Precipitated Silicas have been specially developed to offer viscosity control and thixotropic effect in different kinds of formulas, assuring an uniform distribution of toothpaste in dental cavity.
DENTSIL®DS-230
It is a synthetic Precipitated Silica, which combines good thickening properties and outstanding transparency due its fine particle size and high structure.
It offers viscosity control, stability during storage and an excellent compatibility with active ingredients.
Advantages：
● Improves viscosity control.
● Offers storage stability.
● Avoids liquid separation.
● Provides clarity and transparency in clear gel formulations.
● Excellent compatibility with fluoride and actives ingredients.
● Supplements the action of organic thickeners, allowing the required texture and mouth-feel.

Product quality：
DENTSIL®products meet all criteria established by the Food Chemical Codex (FCC) and the Food and Drug Administration (FDA) standards.
DENTSIL®grades are aimed to Oral and Personal Care applications. They count on Kosher and Halal certifications, which are renewed annually. They also have the food safety certifications QS and CIQ.
Our production site and Quality Management System (QMS) have been accredited with ISO 9001:2015 certification, while our Food Management System (FMS) counts on ISO 22000:2005, FSSC 22000, HACCP and GMP certifications.
Precipitated Silicas are produced under strict quality and microbiological controls based on advanced technologies, being tested and certified by our in-site micro laboratory.
Packaging, Handling and Storage
DENTSIL® products are packed in 12.5 Kg. and 25 kg. white paper bags, palletized and shrink wrapped. They are also available in super sacks. These bags can be handled in the same way as those of any other inert product.
DENTSIL® must be stored in confined, dry and odorless places. The maximum length of storage time is up to two years.
Physiological Effects and Product Safety
DENTSIL® Precipitated Silicas inert, non-toxic powder for the human being and the environment. The radiographic analysis shows the typical spectrum of an amorphous substance that does not contain crystalline elements.
