Zinc Oxide

Zinc oxide is a white, powdery substance that is naturally occurring in the earth's crust. It is widely used in various skincare and cosmetic products for its versatile properties and benefits. Here's a detailed description of zinc oxide:

INCI: Zinc Oxide

CAS: 1314-13-2

Appearance: Zinc oxide typically appears as a fine, white powder with a soft texture. It has a characteristic opaque appearance, which makes it useful for its sun-blocking properties in sunscreen products.

Chemical Composition: Chemically, zinc oxide is a compound made up of zinc and oxygen atoms, represented by the chemical formula ZnO. It consists of zinc ions (Zn2+) and oxide ions (O2-), arranged in a crystalline lattice structure.

Physical Properties:

• Sunscreen Agent: Zinc oxide is widely known for its ability to provide broad-spectrum protection against both UVA and UVB rays from the sun. It acts as a physical barrier, reflecting and scattering ultraviolet radiation away from the skin.
• Non-Comedogenic: Zinc oxide is non-comedogenic, meaning it does not clog pores. This property makes it suitable for use in skincare products, especially for individuals with acne-prone or sensitive skin.
• Anti-Inflammatory: It possesses mild anti-inflammatory properties, which can help soothe and calm irritated or inflamed skin. This makes it beneficial for addressing conditions like sunburn, rashes, and minor skin irritations.
• Antibacterial: Zinc oxide exhibits antibacterial properties, which can contribute to its efficacy in managing certain skin conditions, such as acne and minor wounds.
• Water-Resistant: In addition to its sun-blocking properties, zinc oxide is often used in water-resistant formulations, making it ideal for sunscreen products designed for outdoor activities and water sports.

Applications:

• Sunscreen: Zinc oxide is a key active ingredient in many sunscreen formulations, providing reliable protection against harmful UV radiation.
• Skincare Products: It is used in various skincare products, including lotions, creams, ointments, and diaper rash creams, for its soothing and protective properties.
• Cosmetics: Zinc oxide is utilized in cosmetics such as foundations, powders, and lip balms for its sun-blocking abilities and skin-friendly characteristics.
• Topical Medications: Due to its anti-inflammatory and antibacterial properties, zinc oxide is included in some topical medications and ointments for treating minor skin conditions and irritations.
