        abstract = {Background: The growing demand for multifunctional herbal cosmetics has accelerated the development of formulations that provide both therapeutic and aesthetic benefits. Herbal ingredients such as tea tree oil and green tea extract are well known for their antimicrobial and antioxidant properties, making them suitable for dermatological and cosmetic applications.
Objective: The objective of the present study was to formulate and evaluate an herbal anti-acne and antioxidant foundation stick using tea tree oil and green tea extract, and to assess its physicochemical properties, safety, and effectiveness.
Methods: The foundation stick was formulated using a combination of waxes, oils, pigments, and herbal actives. The prepared formulation was evaluated for various parameters including organoleptic properties, pH determination, melting point, spreadability, adhesion, skin irritation test, antimicrobial activity, and stability studies using standard procedures.
Results: The optimized formulation exhibited desirable organoleptic characteristics such as smooth texture, uniform consistency, and pleasant odour. The pH of the formulation was found to be 6.8, indicating good skin compatibility. The melting point was observed at 54.3°C, suggesting acceptable thermal stability. The formulation showed good spreadability (34 g·cm/sec) and adhesion properties. Antimicrobial studies demonstrated a zone of inhibition of 1.2 cm against acne-causing microorganisms, confirming its anti-acne activity. No skin irritation or surface anomalies were observed, indicating safety and stability of the product.
Conclusion: The formulated herbal foundation stick showed satisfactory physicochemical properties, effective antimicrobial activity, and good stability. It can be considered a safe and effective cosmetic formulation that provides both therapeutic (anti-acne and antioxidant) and aesthetic benefits, making it a suitable alternative to conventional foundation products.},
