AEROSIL® 300 Pharma

AEROSIL® 300 Pharma is colloidal silicon dioxide or silica obtained synthetically from silicon tetrachloride under high-temperature conditions. It is aimed at applications that require silica with a very high specific surface area, which is, in this case, approximately 300 m2/g.

AEROSIL® 300 Pharma is supplied as a white, light, fluffy and extremely fine powder. It is mainly used as an excipient, stabiliser and performance additive in topical pharmaceutical formulations.

Features

Approved for use in pharmaceuticals as an excipient

Synthetic material, of extremely high purity. Non-GMO, BSE-TSE- free and consistent physical properties

Can be used as a glidant for tablet, capsules and powder formulations

Excellent texturiser for oils and emulsions

Specific surface area 300 m2/g

Benefits

Absorbs/binds moisture, which can be advantageous in moisture-sensitive formulations

Small particle size and large specific surface area is advantageous as a flow aid for dry powders in tabletting and capsule filling

Improves tablet hardness during compaction

Excellent flow characteristics in powders

Can be used to make transparent gels

Applications

AEROSIL® 300 Pharma is widely used in topical pharmaceutical products as an emulsion stabilizer, suspending agent and viscosity-increasing agent

AEROSIL® 300 Pharma is also used as an adsorbent dispersing agent for liquids in powders

AEROSIL® 300 Pharma may be added to suppository formulations containing lipophilic excipients to increase viscosity, prevent sedimentation during moulding and decrease the release rate

Improves blending distribution of API's

Desiccant for moisture-sensitive actives

Glidant and anti-caking agent to improve powder properties
