Protein-based Foaming Agent

Updated: 2026-09-19

Overview

Protein-based Foaming Agent is a specialized chemical derived from hydrolyzed proteins, primarily used to generate stable foam in various industrial and commercial applications. Its biodegradable nature and low environmental impact make it a preferred choice over synthetic alternatives. Common sources include animal or plant proteins, which are processed to enhance foaming properties. The agent is versatile, finding use in sectors like construction for lightweight concrete, food processing for aerated products, and firefighting for foam-based extinguishing systems.

Physical and Chemical Properties

The agent typically appears as a light yellow to brown liquid or powder, with a density of approximately 1.0-1.1 g/cm³ in liquid form. It is water-soluble and exhibits high foam stability, which is critical for applications requiring long-lasting foam. Key chemical properties include biodegradability and compatibility with other additives. Unlike synthetic foaming agents, it does not release harmful volatile organic compounds (VOCs), aligning with environmental regulations.

Main Applications

In construction, Protein-based Foaming Agent is used to produce lightweight concrete by introducing air voids, reducing material weight while maintaining strength. It is also employed in food processing to create whipped creams, mousses, and other aerated products. The firefighting industry utilizes it in foam extinguishers, where its stable foam suppresses flames by smothering and cooling. Additionally, it serves in wastewater treatment to float contaminants for removal.

Safety and Storage

While non-toxic, the agent may cause mild skin or eye irritation, necessitating protective gear like gloves and goggles during handling. Proper storage involves keeping it in a cool, dry place away from direct sunlight to prevent degradation. Spills should be contained and cleaned with water, as the agent is water-soluble. Disposal must comply with local environmental guidelines, given its biodegradable nature.

B2B Procurement Guide

When procuring Protein-based Foaming Agent, buyers should prioritize suppliers with certifications for biodegradability and non-toxicity. Bulk purchases often reduce costs, but storage capacity must align with shelf-life considerations. Testing small batches for compatibility with specific applications is recommended. Prices vary by purity and volume, typically ranging from $5-$20 per kg. Ensure the supplier provides technical data sheets for verification.
