A practical guide for interns and young R&D chemists

In industrial chemistry—whether in FMCG, textile processing, detergents, or cleaning chemicals—new raw materials are constantly introduced. As an intern or junior chemist, one of the most valuable skills you can develop is the ability to quickly understand a new chemical and evaluate how it can be used in formulations.
With over two decades of experience managing industrial chemical operations and R&D teams, I’ve noticed that many interns make the same mistake: they focus only on reading the product brochure without truly understanding the chemistry behind the material.
Learning to study a new raw material properly is not just about reading data sheets—it’s about thinking like an industrial chemist. Below is the structured approach I teach to new interns joining the laboratory.
1. Start With the Chemical Identity
Before diving into performance or application, the first step is to understand what the raw material actually is.
Ask the following questions:
-
What is the chemical name?
-
What is the trade name given by the supplier?
-
What is the CAS number?
-
Which chemical family does it belong to?
For example, identifying whether a compound is a surfactant, solvent, polymer, silicone, or chelating agent immediately gives clues about its behavior in formulations.
The CAS number is particularly useful because many suppliers sell the same chemical under different trade names.
2. Study the Technical Data Sheet (TDS)
Once the chemical identity is clear, the next step is to examine the Technical Data Sheet.
The TDS provides essential information about the material’s physical and chemical properties, which directly influence formulation design.
Important parameters to review include:
-
Appearance (liquid, powder, paste)
-
Active content
-
pH value
-
Density
-
Viscosity
-
Solubility in water
-
Cloud point (for surfactants)
-
Temperature and pH stability
An experienced chemist usually summarizes these parameters in a quick reference table to understand how the material might behave in a formulation.
3. Understand the Functional Role
Every raw material exists in a formulation for a specific purpose. Your task as a chemist is to clearly answer the question:
“What function does this chemical perform?”
For example:
In cleaning formulations, chemicals may function as:
-
Surfactants that remove oil and grease
-
Builders that enhance detergent efficiency
-
Foam boosters that improve product performance
In textile processing, chemicals may function as:
-
Wetting agents that help water penetrate fabric fibers
-
Dispersing agents that stabilize dyes
-
Fabric softeners that improve textile feel
Understanding the functional role helps you determine where and how the material can be used.
4. Learn the Mechanism of Action
A good industrial chemist goes beyond memorizing functions and seeks to understand how the chemical works.
Take surfactants as an example. Surfactants contain:
-
A hydrophilic head that interacts with water
-
A hydrophobic tail that interacts with oils
This structure allows surfactants to form micelles, which trap grease and enable it to be washed away.
By understanding the mechanism of action, you develop the ability to predict chemical behavior in new formulations.
5. Study Safety and Handling Information
Industrial chemistry always prioritizes safety and environmental responsibility.
The Safety Data Sheet (SDS) contains critical information regarding:
-
Hazard classification
-
Toxicity and irritation risks
-
Personal protective equipment requirements
-
Storage conditions
-
Spill handling procedures
-
Disposal guidelines
Interns must develop the habit of reviewing SDS documents before handling any new chemical.
6. Evaluate Compatibility With Other Ingredients
Not all chemicals work well together. Some combinations can cause:
-
Precipitation
-
Instability
-
Reduced performance
For example, certain surfactants may lose efficiency in systems with high electrolyte concentrations, while some polymers may degrade in strong alkaline conditions.
Studying compatibility with other formulation components is essential for ensuring product stability and performance.
7. Identify Industrial Applications
The next step is to explore where the chemical is commonly used.
A single raw material can often serve multiple industries.
For example, a nonionic surfactant might be used in:
-
Laundry detergents
-
Dishwashing liquids
-
Textile wetting agents
-
Industrial degreasers
Understanding application areas broadens your knowledge of industrial formulation strategies.
8. Perform Laboratory Testing
Theory alone is not enough in industrial chemistry. The most valuable insights come from practical experimentation.
Typical laboratory evaluations might include:
For cleaning products:
-
Foam stability testing
-
Grease removal tests
-
Hard water performance
For textile chemicals:
-
Wetting time measurement
-
Fabric softness testing
-
Dye compatibility studies
These experiments allow chemists to translate theoretical knowledge into real-world performance evaluation.
9. Compare With Existing Raw Materials
When a new raw material is introduced, the key question for any R&D team is:
“Is this material better than what we are currently using?”
Comparison should include factors such as:
-
Performance
-
Dosage level
-
Cost efficiency
-
Environmental impact
-
Availability
Industrial chemistry is always a balance between performance and commercial practicality.
10. Consider Commercial and Supply Factors
A technically superior chemical may not always be the best choice if it is too expensive or difficult to source.
Important commercial considerations include:
-
Cost per kilogram
-
Supplier reliability
-
Minimum order quantity
-
Shelf life
-
Supply stability
These factors influence large-scale manufacturing decisions.
Final Advice for Interns
One of the best habits a young chemist can develop is maintaining a personal raw material knowledge database.
If you study one new raw material every day, within a year, you will understand hundreds of chemicals commonly used in industrial formulations.
This knowledge will significantly strengthen your ability to:
-
Design formulations
-
Troubleshoot product issues
-
Contribute effectively to R&D projects
Industrial chemistry rewards those who combine scientific curiosity with systematic learning.
Mastering the art of studying raw materials is the first step toward becoming a confident and innovative industrial chemist.
