Vitamin D Composition with Metal Oxides for UV Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals face a dilemma between protecting their skin from harmful UV light and maintaining adequate vitamin D levels, as conventional UV protection products often lead to vitamin D deficiency when used daily, while unprotected exposure to UV light can cause skin damage.
Innovation Solution
A composition that includes a range of cholecalciferol (10 IU/g to 40,000 IU/g) combined with metal oxides like zinc oxide (2% to 80%) to facilitate topical vitamin D delivery while blocking 50% to 99% of UVB light and partially blocking UVA light, preventing skin damage while allowing vitamin D absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional UV protection products are used daily, then skin is protected from harmful UV light, but vitamin D levels become deficient
Solution Approach 1:
The patent combines UV protection functionality with vitamin D delivery functionality into a single topical composition. The composition includes metal oxides (zinc oxide, titanium oxide) for UV blocking and cholecalciferol (vitamin D3) for vitamin D delivery, allowing both functions to be performed simultaneously rather than requiring separate products
Solution Approach 2:
The patent uses metal oxide particles as intermediaries that block UV light from reaching the skin while allowing the vitamin D3 to be delivered to the skin. The metal oxides act as a physical barrier to harmful radiation while permitting the beneficial vitamin D compound to penetrate and be absorbed
2Quantity of substance
If skin is exposed to UV light for vitamin D synthesis, then vitamin D levels are maintained, but skin damage occurs
Solution Approach 1:
The patent converts the harmful effect of UV light into a beneficial outcome by delivering vitamin D3 topically without requiring UV exposure. The composition allows the skin to receive vitamin D benefits while the metal oxide components block the harmful UV radiation that would otherwise cause skin damage
Solution Approach 2:
The metal oxide particles serve as intermediaries that selectively block harmful UV wavelengths while permitting the vitamin D3 compound to reach the skin. This intermediary layer provides UV protection while maintaining vitamin D delivery efficacy
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition effectively delivers vitamin D while protecting the skin from UV light, preventing conditions like vitamin D deficiency and skin damage, and can be used daily without adverse effects on skin appearance or vitamin D balance.
Implementation Method 1
the composition includes one or more metal oxides (e.g., zinc oxide and/or one or more titanium oxides), which function to prevent (or at least limit) UV light from reaching user skin
Implementation Method 2
compositions for facilitating transdermal delivery of vitamin D
Data Source
AI summary
This disclosure relates to a composition for facilitating transdermal delivery of vitamin D while preventing UV light from reaching user skin includes a concentration of cholecalciferol within a range of about 10 IU/g to about 40,000 IU/g. The composition includes one or more metal oxides such as zinc oxide and/or one or more titanium oxides which function to prevent (or at least limit) UV light from reaching user skin. The metal oxide(s) are provided at a concentration within a range of about 10% to about 50% by weight of the total composition.
