Coffee and Pongamia Extract UV Filter Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solar protection formulations often lack broad-spectrum protection against both UVA and UVB radiation, and some UV filters have adverse toxicological, environmental, or sensory effects, necessitating the development of natural and upcycled ingredients that provide effective UV absorption across the entire UV spectrum.
Innovation Solution
A UV filter composition combining coffee bean extract and Pongamia extract, sourced from recycled coffee grounds and Pongamia seeds respectively, which synergistically enhances Sun Protection Factor (SPF) and Protector Factor UVA (PF UVA) when applied together, offering broad-spectrum protection and sustainability through the use of waste materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional UV filters are used to provide solar protection, then SPF and UVB protection are improved, but toxicological and environmental harmful effects worsen
Solution Approach 1:
The patent changes the chemical parameters of UV filters by using plant-derived extracts (coffee bean extract containing chlorogenic acid and Pongamia extract containing pongamol) instead of conventional synthetic UV filters. This substitution maintains UV absorption capability while eliminating toxicological and environmental harmful effects associated with traditional UV filter chemicals.
Solution Approach 2:
The patent utilizes waste coffee grounds as a raw material source for extracting UV-filtering compounds. By converting waste material into a functional UV filter, the invention reduces environmental burden and provides a sustainable, cost-effective alternative to conventional UV filters.
2Device complexity
If single UV filter ingredients are used, then formulation simplicity is improved, but broad-spectrum protection against both UVA and UVB worsens
Solution Approach 1:
The patent combines two distinct plant extracts - coffee bean extract (providing UVB protection through chlorogenic acid) and Pongamia extract (providing UVA protection through pongamol). This merging of two natural extracts creates a synergistic broad-spectrum UV filter that covers both UVA and UVB ranges, achieving comprehensive protection while maintaining formulation simplicity.
3Object-generated harmful factors
If recycled coffee grounds are used as raw material, then environmental sustainability is improved, but extraction process complexity worsens
Solution Approach 1:
The patent employs solvent extraction methodology where common solvents (water, ethanol, or methanol) are used to extract UV-filtering compounds from recycled coffee grounds. This self-service approach allows the waste material to naturally provide its active compounds through simple extraction, minimizing the need for complex processing while maintaining environmental sustainability.
