The quality of a formulation depends directly on the raw materials used. Even small variations can compromise performance, stability, viscosity, and appearance—and may even result in unexpected costs for the industry.

With this in mind, Macler developed TrustScan, a proprietary raw material evaluation methodology designed to ensure that our customers receive reliable, safe products with consistent performance.

Practical validation in the laboratory

TrustScan methodology is based on the principle that compliance with technical specifications and certificates of analysis, while essential, is not sufficient to guarantee the performance of a raw material in a formulation. 

For this reason, all raw materials undergo application testing at SmartLab, where they are incorporated into standard formulations that replicate real-world conditions of use. At this stage, we evaluate not only their physicochemical characteristics but also their functional behavior within the formulation.

Critical parameters such as viscosity, foam, stability, compatibility between components, visual appearance, and formulation efficiency are analyzed.

This practical validation allows us to use in-application performance to identify variations that may not be detectable in conventional analyses. As a result, we reduce the risk of performance deviations in the customer’s production process and provide greater predictability and reliability in the use of raw materials.

The importance of validating the raw material, not just the manufacturer 

It is common for manufacturers’ certifications to be used as the primary criterion for ensuring the quality of a raw material. However, in many cases, companies present themselves to the market as manufacturers when, in practice, they outsource production or simply sell raw materials produced by third parties.    

As a result, a single supplier may work with different manufacturers over time, whether due to sourcing strategy, availability, or commercial considerations. If these changes are not identified and technically evaluated, variations between batches may occur that could impact the performance of the formulations. 

For this reason, TrustScan does not rely solely on supplier qualification or the declared origin of the raw material. The methodology technically validates each product and continuously monitors its performance, ensuring that any changes in the supply chain are detected before they affect the quality delivered to customers.

Greater confidence for developers 

By using raw materials validated by TrustScan, customers benefit from an additional layer of security. 

This means:

• Greater consistency between batches;
• Lower risk of unexpected variations;
• Reduction in rework and production losses;
• Greater predictability in formulation performance;
• Faster approval of new products. 

At Macler, quality is the result of a combination of technical expertise, experimental validation, and continuous monitoring. 

TrustScan brings this concept to life by establishing a structured process for evaluating raw materials, based on application testing, ensuring that every product sold delivers consistent performance over time. 

More than just meeting specifications, TrustScan seeks to ensure what truly matters to the industry: reliability, repeatability, and predictability of performance.
