(Animal Protein Frothing Agent)

Pet protein-based foaming agents are obtained mostly from hydrolyzed keratin or collagen sourced from slaughterhouse spin-offs such as unguis, horns, bones, and hides.

With controlled alkaline or enzymatic hydrolysis, these structural healthy proteins are broken down into amphiphilic polypeptides abundant in amino acids like glycine, proline, and hydroxyproline, which have both hydrophilic (– NH TWO,– COOH) and hydrophobic (aliphatic side chains) functional groups.

This double affinity makes it possible for the molecules to adsorb efficiently at air– water user interfaces during mechanical aeration, minimizing surface area tension and supporting bubble development– an important need for creating uniform cellular concrete.

Unlike synthetic surfactants, pet healthy protein lathering representatives are eco-friendly, safe, and show excellent compatibility with Portland concrete systems as a result of their ionic nature and moderate pH buffering ability.

The molecular weight distribution of the hydrolysate– commonly between 500 and 10,000 Da– directly affects foam security, drain price, and bubble dimension, making process control throughout hydrolysis essential for consistent efficiency.

1.2 Foam Generation Device and Microstructure Control

When watered down with water (usually at proportions of 1:20 to 1:30) and introduced right into a foam generator, the protein solution forms a viscoelastic movie around entrained air bubbles under high-shear problems.

This movie stands up to coalescence and Ostwald ripening– the diffusion-driven development of larger bubbles at the expenditure of smaller sized ones– by forming a mechanically robust interfacial layer reinforced via hydrogen bonding and electrostatic communications.

The resulting foam shows high growth ratios (generally 15– 25:1) and low drain prices (
