As a new foreign trade service provider driven by both technology transformation and export business, HiSiaddi has established a "1+2+3+4=1" service system and can supply PASP polyaspartic acid sourced directly from multiple well-known original manufacturers.
Equipped with R&D capabilities, HiSiaddi has partnered with factories on technology transfer and accurately captured market demands, repeatedly proposing PASP polyaspartic acid formula optimization schemes and application improvement recommendations. Below is a consulting case of HiSiaddi’s PASP formula optimization.

The cooperating client is CHEM FRANCE, a high-end fine chemical group headquartered in Paris, France, with core business covering premium daily chemical care products, industrial specialty additives and landscape water treatment. Its products are sold across over ten EU countries, fully complying with EU REACH regulations, cosmetic safety standards and AFNOR water treatment specifications, ranking as a renowned mid-to-high-end brand in Europe.
The client places an annual order of 26 tons of industrial high-purity PASP polyaspartic acid, applied in two scenarios: as a chelating raw material blended into premium care products and cleaners, and as scale and corrosion inhibitor for commercial complex and ecological park recirculating water systems.
After initial procurement of standard domestic PASP grades, the client encountered successive technical failures including abnormal blended system performance, sharp on-site efficiency attenuation and poor usability. Multiple internal R&D and application debugging attempts failed to resolve the issues thoroughly, disrupting finished product delivery quality and raising on-site operation and maintenance costs. The client formally entrusted HiSiaddi with root cause analysis, formula optimization, process adjustment and long-term technical guidance.
When mixing PASP with anionic surfactants and organic co-solvents for daily chemical additive production, the system gradually turns turbid with fine flocculent precipitates at the bottom after 48 hours of ambient storage. This compromises finished product transparency and causes frequent blockages in filling pipelines.
Portions of the client’s recirculating water systems operate continuously at 70–82°C. After one week of continuous use of standard PASP, chelation and scale inhibition efficiency drop by over 20%, leading to obvious scaling on pipeline and heat exchanger inner walls and shortened equipment maintenance cycles.
Massive foam overflow occurs during application in both daily chemical formulations and open recirculating water systems, damaging product appearance and functionality. Additional defoamer dosage is required, pushing up overall raw material costs.
Free monomer and residual byproduct levels vary widely across different delivery batches of PASP. The client must readjust blending ratios for every new batch, preventing standardized mass production and lowering manufacturing efficiency.
Open-air landscape recirculating water is prone to algae and microbial proliferation. PASP fails to assist in inhibiting colony growth, forming biofilm on pool and pipeline inner walls and accelerating equipment corrosion.
HiSiaddi immediately assigned chemical R&D and application technical engineers to coordinate with the client, adopting a complete workflow: sample testing → root cause identification → raw material modification → formula optimization → on-site process adjustment → standardized control. Full-dimensional rectification was completed within one week.
Full-indicator laboratory analysis of defective products confirmed the core triggers: high free monomer and small-molecule byproduct contents drove blended precipitation and excessive foaming; flawed synthesis processes caused insufficient thermal stability and molecular decomposition under high temperatures; loose production parameter control created batch indicator deviations.
Collaborate with manufacturers to add post-treatment procedures for monomer and byproduct removal, limiting free monomer content below 0.2%. Heat-resistant food-grade modified components are added without impairing environmental performance to optimize molecular structures. Post-modification testing verifies over 94% retention of core efficiency after 15 days of continuous operation at 82°C, completely eliminating high-temperature failure.
Adjust PASP molecular terminal group structures and pair with eco-friendly low-foam additives to drastically reduce surface activity while retaining full chelation and scale inhibition performance, fundamentally suppressing foam generation and eliminating the need for extra defoamers.
Simulate diverse temperatures and storage environments per the client’s actual production ratios to conduct over one hundred compatibility trials, redefining component addition sequences and ratio ranges to eliminate adverse inter-component reactions. Optimized blended systems remain clear without stratification or precipitation after 3 months of sealed ambient storage.
Issue exclusive application plans differentiated across three working conditions: daily chemical manufacturing, closed recirculating water and open landscape water, clarifying reagent dosing concentrations, feeding sequences and storage requirements. For open water bodies, optimize system blowdown and circulation frequency to work in tandem with existing bacteriostatic reagents and suppress biofilm formation.
Assist manufacturers in solidifying full production parameters and additive dosing standards, requiring third-party test reports for every batch and limiting key indicator deviations within 0.15%. Compile a standardized PASP Usage Manual for the client to facilitate reference by frontline operators.
· Blended finished product quality restored to standard levels, filling systems operate smoothly, product yield recovers to normal and overseas order deliveries proceed without disruption.
· Stable scale inhibition and chelation performance under high-temperature conditions completely resolve equipment scaling issues, doubling equipment cleaning and maintenance cycles.
· Foaming defects fully eliminated; defoamer usage discontinued, cutting raw material costs per production batch.
· Consistent batch performance enables full standardized production, eliminating repeated blending ratio adjustments and significantly lifting manufacturing efficiency.
· Algae and microbial proliferation in open water bodies are controlled, with markedly reduced pipeline corrosion rates.
The client highly recognized the technical rectification results, renewed the annual 26-ton PASP framework procurement agreement and awarded full supply of supporting eco-friendly additives and chelating agents to HiSiaddi.
For overseas mid-to-high-end daily chemical and commercial recirculating water clients, beyond basic indicators, blended compatibility, thermal stability, low-foam performance and batch consistency determine final application effectiveness. HiSiaddi addresses challenges spanning raw material, formula and on-site application layers, resolving immediate malfunctions while establishing standardized usage systems to fully guarantee stable client production and operation, consolidating long-term cooperative relationships.
