ELECTROSTATICALLY SPRAYABLE TANNING FORMULATION

Smart overview of the Invention

The invention introduces an electrostatically sprayable topical formulation designed to give the skin a tanned appearance without ultraviolet radiation exposure. This formulation ensures even application across the skin, maintaining its skin-caring effects. The method addresses common issues with uneven application and streaking associated with traditional tanning products applied by hand or conventional aerosols.

Background

Traditional methods for achieving a tanned look often involve UV exposure, which can accelerate skin aging and increase cancer risk. Existing sunless tanning products, typically in lotion or gel form, often result in uneven application and streaks due to manual application methods. Aerosol sprays, while offering an alternative, use environmentally harmful propellants and often fail to provide uniform coverage.

Innovation

This formulation leverages electrostatic spraying technology, which avoids the need for propellants and ensures a consistent flow of product. It addresses the limitations of previous formulations that were not suitable for electrostatic spraying due to their electrical properties or high viscosity. The invention combines specific components to optimize sprayability and coverage.

Composition

• Ethanol: Less than 50 wt.-%
• Water: 20 to 55 wt.-%
• Emollients: 0.5 to 5.0 wt.-%, liquid at 20°C with a log Kow of 2 to 10
• Antioxidants: 0.05 to 2.0 wt.-%
• Tanning Agents: 2 to 20 wt.-%
• Cosmetic Additives: 2 to 15 wt.-%

Application

The formulation can be applied using any electrostatic device suitable for cosmetic use, such as the IONIQ ONE Sprayer, eliminating the need for propellants. This method ensures full coverage without streaking, as demonstrated in the figures where the formulation achieves an even tan compared to untreated skin.
