- Chemical Structure Description
Neusilin® is amorphous and contains either tetrahedron or octahedron of Al, octahedron of Mg and tetrahedron of Si which are randomly attached to form a complex three dimensional structure. Neusilin® does not possess repeating units of a defined monomer.
Features & Benefits
- Characteristics
- Neusilin® is Magnesium Aluminometasilicate in either fine powder or granule form.
- Neusilin® is represented by an empirical formula Al2O3·MgO·1.7SiO2·xH2O.
- Neusilin® is amorphous, possesses very large specific surface area and has high oil and water adsorption capacity.
- Neusilin® is superior in compressibility which enables to make hard tablets at low compression force. It can also improve hardness of other fillers and binders of low concentration.
- Compounding with Neusilin® helps stabilize moisture sensitive as well as lipophilic APIs.
- Neusilin® is stable against heat and has a long shelf life.
- Neusilin® is available in various grades. The grades differ in their bulk density, water content, particle size and pH.
- Neusilin® is an excellent carrier for solid dispersion via self-micro emulsifying drug delivery system (SMEDDS) and Hot-Melt Extrusion.

Function:
- Cleaner
- Mattifier
- Body care
Stabilizer:
- Base cosmetics
- Color cosmetics
Production:
- Sodium polyacrylate
- Gel formulation (face/eye masks)
- Cosmetic Application
Unique properties of Neusilin® UFL2 make it an ideal component for cosmetic preparations. Although chemically the same as traditional crystalline Magnesium Aluminum Silicate (MAS), Neusilin® is both structurally and functionally very different. While MAS is used as a thickener, Neusilin® does not develop viscosity or form gel. It is formulated in facial care products including lotions, eye shadow, cleansers, powders, acne and oily skin treatments and deodorants.
Functionalities:
- Excellent sebum absorption capability
- High oil and water absorption
- Deodorant properties
- Pigment dispersion aid
- Anticaking agent
- Opacifying agent
- Ideal for powder lotions and other personal care products
- Oil Adsorption Application
Neusilin® possesses excellent adsorption capacity for its extremely large specific surface area and porous reticulate structure. It can adsorb up to 330% of its own weight and maintains its powdery state. This superior adsorption capacity makes Neusilin® ideal for applications including oily and acne skin treatments.
- Deodorization Application
Neusilin® works to eliminate odor in two ways. It can neutralize odor through making hydrogen bonds with bad odor compounds such as isovaleric acid or through covalent bonding with ammonia and trimethylamine. It can also physically absorb foul odor compounds by trapping them into its highly porous structure.
- Dosage and Safety
Neusilin® is safe with no reports of adverse reactions and is an accepted ingredient by the USP/NF and JPC. Based on the usage as an excipient in various formulations in Japan, Neusilin® up to 1.05 g can be used for oral uptake per day.* There are no established maximum oral intake limits specified by US-FDA.

Technical Details & Test Data
- Conclusions
Neusilin® is a totally synthetic magnesium aluminometasilicate with exceptional excipient properties to improve API delivery and quality of oral solid-dosage form pharmaceuticals. Neusilin® is available in four grades and the two different pH options make it a versatile excipient for a wide-variety of applications.
With over 500 pharmaceutical preparations and a market presence of over 60 years in Japan, Neusilin® is well accepted by the formulators world-wide as an aid for formulations containing antibiotics, oily actives, poorly water soluble APIs, herbal mixtures, vitamins, etc. Neusilin® is also used as carrier for preparation of solid dispersion and self-micro emulsifying drug development systems.
Neusilin® has been demonstrated as an excellent adsorbent carrier for solid dispersion preparation via hot melt granulation, Self MicroEmulsifying Drug Delivery Systems (SMEDDS) for BCS class II drugs such as meloxicam, naproxen, ketoprofen, glyburide and other highly permeable but poorly water soluble drugs. The most exciting use of Neusilin® is in Hot Melt Extrusion (HME). Neusilin® allows preparation of stable amorphous drug complex without any addition of polymers, waxes or plasticizers normally associated with HME. The samples can be recovered as amorphous powder and converted to highly stable tablets through direct compression.
