What it is: A fatty alcohol (not drying!).
Used for: Thickening, stabilizing emulsions, improving texture.
Beginner value: Ideal to learn emulsification.
Compatibility: Works with most emulsifiers.

4. Propylene Glycol

What it is: A humectant + universal solvent.
Used for: Enhancing spreadability, dissolving actives, increasing absorption.
Safety: Very safe for beginners.
Common in: Personal care, pharma labs, school-level experiments.

5. Sodium Hydroxide Flakes (NaOH)

What it is: A strong base (caustic soda).
Used for: pH adjustment, saponification, titration experiments.
Safety: Requires supervision.
Tip: Always add NaOH to water - never the opposite.

6. Citric Acid (Anhydrous)

What it is: A mild organic acid.
Used for: pH control, buffer preparation, cleaning studies.
Safety: Beginner-safe.
Seen in: School experiments, cosmetic pH adjustment.

7. Triethanolamine (TEA)

What it is: A neutralizer and emulsifier stabilizer.
Used for: pH adjustment, viscosity boosting in gels & lotions.
Common users: Cosmetic students, personal care labs.

8. L-Ascorbic Acid (Vitamin C)

What it is: A powerful antioxidant.
Used for: Oxidation studies, stability testing, skin research.
Tip: Always protect from heat and light.

9. Cetostearyl Alcohol

What it is: A blend of cetyl + stearyl alcohol.
Used for: Thickening emulsions, improving stability.
Great for: Beginners practicing cosmetic formulation.

10. Lactic Acid

What it is: A mild AHA used widely in cosmetic science.
Used for: Exfoliation, pH regulation, biochemical experiments.
Safety: Mild but requires correct dilution.

11. Salicylic Acid (BHA)

What it is: An oil-soluble exfoliant.
Used for: Acne studies, exfoliation experiments.
Tip: Dissolve in Propylene Glycol or ethanol for best results.

12. Deionized Water (DI Water)

What it is: Water with ions removed.
Used for: Dilution, mixing, cleaning, solution preparations.
Importance: Fundamental for accurate test results.

13. Sodium Lauroyl Sarcosinate

What it is: A mild amino-acid surfactant.
Used for: Gentle cleansers, face washes, shampoos.
Beginner insight: Great for studying surfactant foaming behavior.

14. EDTA Disodium

What it is: A metal-ion chelating agent.
Used for: Preventing formulation instability, improving preservative efficiency.
Safety: Very safe.

15. Kojic Acid Dipalmitate (KAD)

What it is: A stable form of Kojic Acid.
Used for: Skin-brightening studies, depigmentation formulas.
Advantage: Does not oxidize like pure Kojic Acid.

16. Cocomonoethanolamide (CMEA)

What it is: Foam booster + viscosity enhancer.
Used for: Shampoos, liquid cleansers, surfactant systems.
Great for: Beginners studying viscosity behavior.

17. PEG-150 Distearate

What it is: A polymer thickener.
Used for: Opacifying and stabilizing shower gels & shampoos.
Beginner value: Teaches polymer-thickening mechanics.

18. Guar Hydroxypropyltrimonium Chloride

What it is: A cationic conditioning polymer.
Used for: Hair conditioners, serums, slip enhancement.

19. Alkyl Benzoate

What it is: A lightweight emollient.
Used for: Sunscreens, creams, lightweight lotions.
