Natural Surfactants

What Are Natural Surfactants?

Natural surfactants reflect true gastrointestinal digestive conditions from stomach to colon and enhancing more accurate predictions of drug solubility and absorption. Natural surfactants such as bile salts and lecithin produced from a wide range of animal, plant, food-based, and semi-synthetic sources — accurately reflect the complete gastrointestinal environment.

These natural systems offer simple, cost-effective alternatives that can reduce major bio failures, IVIVC gaps and shorten 30% development timelines.

Why Natural Surfactants Matter

Understanding the critical role of natural surfactants in pharmaceutical development

Accurate Bio-Relevance

Mirror true gastrointestinal conditions from stomach to colon, providing the most accurate reflection of real in-vivo drug behavior and absorption patterns.

Enhanced Predictions

Significantly improve predictions of drug solubility and absorption, reducing the gap between in-vitro testing and in-vivo performance.

Cost-Effective

Offer simple, economical alternatives to conventional methods, reducing major bio-failures and cutting development costs by up to 30%.

Faster Development

Shorten development timelines significantly by reducing the need for reformulation and repeated studies due to IVIVC failures.

Reduced Bio-Failures

Minimize unexpected biological failures by using surfactants that accurately represent real physiological conditions during early development.

Natural Sources

Derived from animal, plant, and food-based sources, offering bio-compatible and environmentally sustainable alternatives.

Physicochemical Advantages

The physicochemical properties of natural surfactants closely match real in-vivo conditions, allowing them to more accurately reflect/predict drug behavior in the body.

Critical Micelle Concentration (CMC)

Natural surfactants have CMC values that mirror physiological conditions, ensuring accurate solubilization behavior during dissolution testing.

pH Sensitivity

Natural bile salts and phospholipids respond to pH changes similarly to the gastrointestinal tract, from acidic stomach to neutral intestinal environments.

Mixed Micelle Formation

Natural surfactants form mixed micelles with bile salts and phospholipids, replicating the complex solubilization mechanisms in vivo.
