Consistent Quality for Reliable Daily Chemical Formulations
From raw material verification to batch testing and controlled production systems, we focus on delivering stable additive performance for home care, personal care, and oral care applications.
Quality Control at the Core of
Daily Chemical Supply
At Shandong Landu New Material Co., Ltd., quality control is a core part of how we support customers in the daily chemical industry. For products such as detergents, cleaners, hand sanitizers, shampoos, facial care products, and toothpaste, additive consistency directly affects viscosity, texture, suspension behavior, appearance, and user experience. That is why quality control must go beyond basic inspection and extend through raw materials, production processes, batch verification, and final delivery readiness.

Quality Starts with Raw Materials
Consistent finished products begin with controlled raw material selection. LANDERCOLL's quality assurance materials state that reliable raw materials are essential for ensuring consistency and product performance. This foundation is especially important for cellulose ether and related additives, where small variations in upstream inputs can affect final viscosity, solubility, stability, and rheology behavior.
Laboratory-Based Quality Verification
LANDU is supported by fully equipped laboratories in Jinan with qualified engineers and chemists carrying out regular testing on both raw materials and finished products. An independent R&D center and laboratories implement rigorous quality control protocols to ensure product reliability.
Batch-to-Batch Testing
Every production batch undergoes comprehensive physical and chemical analysis to maintain quality consistency. These test parameters directly influence performance in detergents, personal care products, and oral care systems.

Controlled Production Systems
LANDU uses advanced technology and equipment, including DCS quality monitoring and automatic packing systems. DCS & SIS systems maintain quality and consistency, supporting a manufacturing environment designed for tighter process control, improved operational stability, and more consistent output. For daily chemical additives, customers depend on repeatable viscosity, clarity, thickening efficiency, and formulation compatibility across multiple orders.
Real-Time DCS Monitoring
Distributed control systems track temperature, pressure, and reaction parameters in real time.
SIS Safety & Integrity
Safety Instrumented Systems maintain operational integrity and prevent deviation from spec.
Automated Packaging Control
Precision packing ensures consistent weight, sealed quality, and traceable outbound logistics.
Quality Control for Daily Chemical Applications
Our quality system supports the full LANDU daily chemical additive portfolio. For these applications, quality control is directly linked to practical formulation results — a stable additive helps manufacturers maintain the intended product feel, appearance, storage performance, and end-user experience.
Applications Covered by Our Quality System
Compliance and System Assurance
LANDU and LANDERCOLL materials highlight quality and compliance references including ISO standards, EU REACH, and EcoVadis. These references communicate that quality control is supported not only by internal testing, but also by structured management systems and international compliance awareness.
How Quality Control Benefits Customers
Our quality control system is designed to create real value for customers.
More Consistent Product Performance
Regular testing and controlled production help reduce variability between batches, giving formulators reliable inputs for every production run.
Greater Formulation Reliability
Stable raw material quality supports better viscosity control, suspension behavior, and application feel in end products across home care, personal care, and oral care.
Improved Purchasing Confidence
A quality system supported by laboratories, engineers, and monitored production helps buyers reduce supply risk and simplify procurement decisions.
Better Long-Term Cooperation
Quality consistency is a key condition for repeat orders, formula continuity, and international business growth built on mutual trust and reliability.
At Shandong Landu New Material Co., Ltd., quality control is not treated as a single inspection step. It is an integrated system that combines raw material screening, laboratory verification, batch testing, controlled production monitoring, and compliance-oriented management.
Whether you are developing a detergent, cleaner, sanitizer, shampoo, facial care product, or toothpaste formula, we aim to support your work with materials you can use with greater confidence.
