As a new-type foreign trade service provider driven by both technology transformation and foreign trade services, HiSiaddi has established a "1+2+3+4=1" service system and can supply GLDA tetrasodium salt from multiple well-known original manufacturers.
Endowed with R&D capabilities, HiSiaddi repeatedly puts forward formulation optimization schemes and application improvement suggestions for GLDA tetrasodium salt by leveraging technological cooperation with factories and precise insight into market demands. Below is a consultation case of HiSiaddi on GLDA tetrasodium salt formulation optimization.

The purchaser is BEAUTY SPAIN, a high-end personal care group based in Barcelona, Spain, specializing in light luxury salon skincare, plant essential oil wash products and high-end tableware cleaners sold across Southern Europe. The brand strictly follows EU cosmetic regulations, CLP classification standards and ECO-label eco-labels, ranking among top mid-to-high-end enterprises in daily chemical and household cleaning sectors. The client purchases 38 tons of general-grade GLDA tetrasodium salt annually as chelating agents and stabilizers compounded into three product lines: skincare emulsions, transparent washing liquids and concentrated cleaners.
After mass application of domestically supplied standard GLDA tetrasodium salt, multiple technical failures emerged on production lines and finished terminal goods. The internal R&D team adjusted ratios and production parameters repeatedly yet failed to eliminate all issues completely. This dragged down finished product yield and rendered some batches undeliverable due to unqualified appearance and stability. The client formally entrusted HiSiaddi’s technical team to conduct root cause tracing, formulation optimization, process rectification and long-term application guidance.
1. Turbid compound systems with flocculent precipitates When GLDA tetrasodium salt is compounded with anionic surfactants and plant extracts to produce transparent washing products, the system gradually loses transparency after 3 days of room-temperature storage, with tiny flocculent impurities precipitating at the bottom. This ruins product appearance failing high-end daily chemical aesthetic standards and easily blocks filling pipelines.
2. Poor formulation stability under high & low temperature conditions When finished goods are stored in summer warehouses (45℃) or transported via cold chains in winter (around 0℃), active ingredient activity declines, emulsions delaminate and viscosity of washing products fluctuates abnormally, failing shelf life stability standards.
3. Insufficient synergistic chelation effect For concentrated cleaners used in hard water regions, weak metal ion complexing capacity of GLDA leads to product discoloration and attenuated detergency.
4. Abnormal foaming performance When applied to low-foam tableware cleaners, GLDA generates excessive foam requiring extra defoamer addition, which raises raw material costs and conflicts with the brand’s green formulation positioning.
5. Obvious batch performance fluctuations Different batches of incoming GLDA tetrasodium salt contain inconsistent by-products and residual impurities. Formula ratios need readjustment for every new batch of raw materials, prohibiting standardized mass production and drastically lowering production efficiency.
HiSiaddi formed a special task force consisting of daily chemical application engineers and fine chemical formulators, completing full-process rectification within 6 days following the workflow: sampling full-item testing → root cause identification → raw material modification → compatibility optimization → production process adjustment → standardized management.
1.
Sampling & chemical testing to identify root causes Physicochemical indicators and component analysis were performed on multiple batches of raw materials in use. Core inducements were confirmed: high residual small-molecule by-products and incompletely reacted intermediates generated during synthesis were the primary triggers of precipitation and excessive foaming in compound systems. Basic formulations lacked high/low temperature resistance modification leading to insufficient thermal stability and low-temperature compatibility of molecular structures. Loose production control caused large batch-to-batch differences in impurities and by-products, eventually triggering all application defects.

3.
Raw material purification & temperature resistance modification Cooperated with manufacturers to optimize post-treatment procedures by adding vacuum by-product removal and precision filtration processes to strictly control residual intermediate content within limits. Without compromising environmental performance or increasing irritation, food-grade dual high/low temperature stabilizers were added to optimize molecular structures. After rectification, raw materials withstand a wide temperature range of 0℃~45℃ with active ingredient retention rate stabilized above 98%.
4.
5.
Low-foam modification optimization Adjusted the ratio of GLDA tetrasodium salt derivatives and matched eco-friendly low-foam synergistic components. Foam generation was drastically reduced at the source while maintaining intact chelating performance, adapting to low-foam cleaner formulations and eliminating defoamer usage entirely.
6.
7.
Multi-round compatibility tests to optimize compound schemes Hundreds of simulated compound tests were carried out in strict accordance with the client’s actual ratios, production temperatures and storage conditions across three major product lines. Optimal feeding sequences, mixing speeds and reaction temperatures were finalized. Optimized systems remain clear and uniform without delamination or flocculent precipitation after 90 days of sealed room-temperature storage and cyclic high-low temperature testing.
8.
9.
Standardized on-site production & application process guidance Issued exclusive operating guidelines for different product lines: separate feeding intervals and mixing durations defined for skincare, washing and cleaning product categories; specified raw material storage temperature zones to avoid direct sunlight and extreme temperature storage; adjusted dosage for hard water scenarios to strengthen metal ion complexing capacity.
10.
11.
Tightened production standards to unify batch quality Assisted manufacturers in solidifying full sets of production parameters and purification process standards, requiring third-party full-item test reports attached to each delivery batch with key indicator deviations controlled within 0.2%. A Standardized GLDA Tetrasodium Salt Application Manual was compiled for the client to facilitate reference by production line staff and realize full-process standardized operation.
12.
1. Appearance and stability of compound finished products fully meet standards, pipeline blockage during filling is completely eliminated, finished product yield returns to normal levels and delivery suspensions are resolved.
2. Product properties remain stable under high-temperature storage and low-temperature transportation; delamination and abnormal viscosity issues are fully eliminated, complying with brand shelf life standards.
3. Chelating capacity is significantly enhanced; cleaners remain colorless with stable detergency in hard water environments. Low-foam modification eliminates defoamer demand and cuts overall raw material costs.
4. Consistent raw material batch performance removes repeated formula debugging requirements, lifting production line efficiency and reducing labor operation costs.
5. The annual 38-ton order is fulfilled stably. The client highly recognizes HiSiaddi’s technical rectification capacity and subsequently entrusts HiSiaddi with full supply of all daily chemical chelating agents and auxiliaries.
For overseas mid-to-high-end daily chemical and cleaning clients selecting GLDA tetrasodium salt, beyond basic chelation indicators, compound compatibility, wide-temperature stability, low-foam performance and batch consistency are core factors determining finished product quality and mass production feasibility. Restricted by synthesis and post-processing shortcomings, standard general-grade raw materials easily trigger various defects in complex compound systems.
HiSiaddi implements purification and modification at the raw material end, paired with optimized compound schemes and operating workflows tailored to the client’s actual production conditions. We not only resolve immediate technical failures but also establish standardized application systems to fully guarantee client production and product quality, deepening long-term cooperation through professional technical services.
