What Is a Surfactant?
A plain-language introduction to surfactant structure and the roles surfactants can play in cleaning.
Planned topicTandell Academy · Knowledge Centre
Cleaning science without the unnecessary barrier.
Free, original explanations that connect scientific concepts to cleaning products, product-development decisions, laboratory testing, and marketing claims.
Useful enough to answer the first question. Clear enough to share across technical, sales, and marketing teams.
How to use this centre
Understand the concept before interpreting the result.
Each article begins with a short explanation, connects the idea to a real cleaning product, identifies common misconceptions, and explains what the science can—and cannot—support. New topics will be added one at a time as they are written and reviewed.

Sinner's Circle: The Four Factors That Shape Cleaning Performance
Why chemistry, mechanical action, time, and temperature must be considered as one cleaning process.
Read article →Surface Tension
What surface tension means, why water beads, and how the measurement relates to cleaning products.
Planned topicFoam and Its Relationship to Cleaning
What foam can tell you, what it cannot prove, and why more foam does not automatically mean more cleaning.
Planned topicDilution, Dosing and At-Use Concentration
How concentrates, ratios, dose, and active concentration change the product the user actually applies.
Planned topicWetting vs Cleaning
Why improved spreading may help a cleaner reach a surface but does not, by itself, prove better soil removal.
Planned topicWater Hardness and Cleaning
How calcium and magnesium can alter cleaning chemistry, residue, foam, and comparative test results.
Planned topicEditorial approach
Plain language without oversimplifying the conclusion.
Tandell Academy explains technical ideas for practical decisions. Articles distinguish a useful indicator from proof of product performance and identify when application-specific testing is still required.
