Polyaspartic Acid (PASP) is a biodegradable polymer inspired by natural proteins. As a chelant and scale inhibitor it is both mild and eco-friendly. It forms stable complexes with metal ions such as calcium, magnesium, iron, and copper to prevent scale formation, while degrading naturally in the environment without long-term accumulation — an ideal substitute for…

As control over total-phosphorus discharge tightens across regions, traditional phosphorus-based scale inhibitors face restrictions in some applications, and phosphorus-free, biodegradable alternatives are gaining traction. PESA (Polyepoxysuccinic Acid) is a prime example: it contains no phosphorus and degrades readily in the natural environment, yet still delivers good scale inhibition and dispersion against calcium carbonate and calcium…

Benzalkonium chloride (BAC), a mixture of alkylbenzyldimethylammonium chlorides (typically C12, C14, and C16 homologs), is a cationic surfactant with broad-spectrum bactericidal activity. Its efficacy is concentration-dependent, strongly selective for Gram-positive bacteria, and significantly compromised against Pseudomonas aeruginosa and in the presence of organic matter or hard water. Selective Activity: Gram-Positive vs. Gram-Negative BAC is markedly…
