OUR PRODUCTS:
For Parenteral Biopharmaceuticals
In the development of biotechnology-based therapeutics, such as antibody medicine, sugar excipients are often used in formulations to stabilize protein APIs.
The following are our two main products for parenteral applications, injectable grade Trehalose SG and Maltose PH.
― High Purity Trehalose ―
Trehalose SG

Trehalose is a dihydrate crystalline non-reducing disaccharide consisting of two glucose molecules linked by an α,α‒1,1 bond. Trehalose SG has been supplied and used for parenteral formulations because of its high purity and low endotoxin specification. Trehalose is unique in its remarkable acid tolerance as well as heat stability and shows no Maillard reaction when heated in solutions containing amino acids. It shows several benefits in stabilizing protein structures when proteins are lyophilized or frozen, and is also known to prevent cells and liposomes from damage during freezing and thawing.
APPLICATIONS
- Stabilization of antibodies, peptides, and vaccines for injection
- Additive for culture medium (e.g., stem cells)
- Preservation of platelets
REGULATORY APPROVALS
- JP / USP-NF / Ph.Eur. / CP
- US Type IV DMF
- Halal
CHARACTERISTICS

― High Purity Maltose ―
Maltose PH
Maltose is a reducing disaccharide consisting of two glucose molecules linked by an α-1,4 bond. Maltose PH is highly purified maltose monohydrate crystalline with a low endotoxin specification. It can be used for parenteral applications including injection, intravenous fluid, and cell culture carbon sources.

APPLICATIONS
- Active ingredient for infusion fluid
- Solubility enhancer and stabilizer of freeze-dried anti-cancer agents for injection
- Stabilizer of Immunoglobulins
REGULATORY APPROVALS
- JP/ CP
- US Type II DMF
- Halal
CHARACTERISTICS

For Oral Drug Development
Sugar excipients are often used in solid oral dosage forms such as tablets. They are used for different purposes including taste improvement, tableting and granulation.

― High Purity Trehalose ―
Trehalose 100PH
Trehalose 100PH is a highly purified trehalose without an endotoxin specification. Since it shows great benefit in masking unpleasant taste and odor, Trehalose 100PH can be used in syrup, dry syrup as well as chewable tablets, making it a more preferred additive for oral drug development.
APPLICATIONS
- Additive for oral solutions
(e.g., stabilizer, taste improver, solubility enhancer for minerals) - Excipient for solid oral dosage forms
(e.g., tablets)
REGULATORY APPROVALS
- JP / USP-NF / Ph.Eur.
- Halal
