Frequently Asked Questions (FAQ)
Q1. What is the difference between cosmetics and cosmeceuticals?
Cosmetics are products used to cleanse, beautify, or enhance appearance without affecting body functions, whereas cosmeceuticals contain biologically active ingredients that provide both cosmetic and therapeutic benefits, such as anti-aging creams and medicated skin-care products.
Q2. Why are preservatives added to cosmetic products?
Preservatives prevent the growth of bacteria, fungi, and other microorganisms in cosmetic products. They help extend shelf life and ensure product safety during storage and use.
Q3. What is the role of surfactants in shampoos and cleansers?
Surfactants reduce surface tension, allowing dirt, oil, and impurities to be removed from the skin and hair. They are the primary cleansing agents used in shampoos, face washes, and soaps.
Q4. What are herbal cosmetics and why are they becoming popular?
Herbal cosmetics are products formulated using natural plant-based ingredients such as aloe vera, neem, turmeric, and essential oils. They are popular because consumers often prefer natural alternatives with fewer synthetic chemicals.
