Cosmetic Formulation Questions & Answers
Answers to common questions about Formula Chemistry, our formulas and services, and getting started in cosmetic formulation the scientific way, from Dr. SamiUllah, Ph.D. in Chemistry.
About Formula Chemistry
Who is behind Formula Chemistry?
Formula Chemistry is founded and run by Dr. SamiUllah, a Ph.D. in Chemistry and cosmetic formulation specialist. Every formula, guide, and ingredient profile on the site is written and reviewed by him, so the content is grounded in real formulation science rather than repackaged recipes. More about us.
Are the formulas on this site original?
Yes. Every formulation and guide here is original and self-developed, built from established chemical principles rather than copied from other sites. They are shared to demonstrate how formulation logic, ingredient interactions, and stability actually work.
How is Formula Chemistry different from other skincare and DIY sites?
Most skincare and DIY sites give you recipes to follow blindly. Formula Chemistry is science-first: the goal is to explain why a formula works, how each ingredient behaves, and how your choices affect stability, performance, and safety, so you understand the chemistry instead of just copying steps. Every piece is authored by a Ph.D. chemist.
Are your formulas safe to use?
They are developed on sound chemical principles and shared for educational and small-batch personal use. As with any cosmetic, the outcome depends on your ingredients, skin type, and process, so always patch test, take care with active ingredients, and carry out stability and safety testing before any commercial use. Nothing here replaces professional or medical advice.
Can I use your formulas to make products I sell?
The free formulas are provided for education and small-batch personal use, not as market-ready products. To sell, you are responsible for your own safety assessment, stability and challenge testing, and regulatory compliance for your region. If you would like help taking a formula to a sellable standard, you can book a one-to-one session with the chemist. Book a session.
Can I book the chemist for one-to-one help with my formulation?
Yes. One-to-One Booking is a paid session where you work directly with Dr. SamiUllah on your own questions, whether that is fixing a formula, choosing ingredients, or planning a product, and you are guided through it fully. Book one-to-one help.
Do you offer courses to learn cosmetic formulation?
Yes. Our workshops and courses teach cosmetic formulation the scientific way, from ingredient chemistry through to a launch-ready product, including a structured 12-week programme led by Dr. SamiUllah. See workshops and courses.
Getting Started with Formulation
Where should a complete beginner start on this site?
Start with the Encyclopedia to learn what each ingredient does, browse the Free Formulas to see how real formulas are built, and use the Formulation Calculator to work in percentages. When you are ready to formulate properly, the workshops take you from the basics to your own finished product.
Do I need a chemistry degree or a lab to formulate cosmetics?
No. You can learn to formulate safe, effective products with a structured method and a handful of basic tools: a scale, a heat source, and good hygiene. Understanding the underlying chemistry is what separates confident formulators from people following recipes blindly, which is exactly what this site teaches.
What basic equipment do I need to start formulating?
Very little to begin: an accurate digital scale that reads to 0.01 grams, a heat source with heatproof beakers, a thermometer, a small hand mixer or mini whisk, pH strips or ideally a pH meter, and clean, sanitised containers. Keep a dedicated set separate from kitchen use for hygiene.
What is the difference between a cosmetic chemist and a cosmetic formulator?
A cosmetic chemist typically holds a chemistry or related degree and works across the science of a product. A cosmetic formulator is anyone who develops stable, effective formulas, with or without a formal degree, largely through training and hands-on experience. In practice the line blurs, and the science you actually understand matters more than the title.
