Carbopol® Polymers

Carbopol® polymers provide highly effective controlled-release properties for oral tablets at low usage levels, critical rheological and bioadhesive properties for topical formulations, and patient-centric benefits across multiple dosage forms.  

Discover Carbopol® Polymers

Webinar: Novel Solubility-Enhancing Excipients for Oral and Injectable Drug Products

This webinar unveils two new polymer technologies from LLS Health for increasing drug solubility: oral-grade Apinovex™ and injectable-grade Apisolex™ polymers. Learn how these polymers enable scalable, reproducible manufacturing of drug products, intellectual property (IP) protection, and lifecycle management with 505(b)(2) filings.

Oral Solid Dose

LLS Health excipients for solid oral drug delivery offer excellent physical properties, such as tablet hardness and low friability, over a wide range of compression forces and come in both powder and granular forms. 
Drug Eluting Device

Implantable Devices

Implantable drug-eluting systems (also referred to as implantable devices) offer several unique advantages over conventional oral or other parenteral drug delivery methods.

Highlighted Excipients

Topical Cream

Carbopol® Polymers

Carbopol® polymers are well known for their versatility and ease of use as pharmaceutical excipients. 
Oral Solid Dosage

Apinovex™ Polymers

Apinovex polymers enable formulators to enhance the solubility of BCS Class II and IV APIs and develop more efficient oral dosage forms with high, stable drug loading.

Apisolex™ Polymer

Apisolex™ Polymer is an injectable-grade excipient that is a safe, GMP-validated, polyamino acid-based polymer that enhances the solubility of BCS Class II and IV APIs by 50,000-fold

Noveon® Polycarbophil

Noveon® Polycarbophil can provide enhanced lubrication functionality to ophthalmic drug formulations and excellent controlled release characteristics in oral drug delivery applications.

Pathway® TPU Excipients

Pathway TPU Excipients offer controlled drug release and compatibility with a wide range of active pharmaceutical ingredients (APIs).

Other Topical IID Ingredients

In addition to our traditional IID-listed polymers that can help improve the feel and performance of topical pharmaceutical formulations, our portfolio also includes emollients, humectants, emulsifiers, and surfactant thickeners. 

Key CDMO Services

CDMO - formulation
