Self-tanning Composition with Vitamin D for Extended Duration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sunless tanning products, such as those containing dihydroxyacetone (DHA) or erythrulose, provide temporary results due to their short duration as they react with dead skin cells, necessitating a more effective and longer-lasting solution for achieving a natural-looking sun tan without harmful sunlight exposure.
Innovation Solution
A sunless tanning composition combining dihydroxyacetone or erythrulose with vitamin D compounds, along with physiologically acceptable carriers, excipients, aesthetic components, skin conditioning agents, and skin care agents, applied via a towelette or directly to the skin, which can be used without sunlight or ultraviolet radiation exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If self-tanning compositions containing dihydroxyacetone or erythrulose are applied to the skin, then a sun tan effect is achieved without sunlight exposure, but the tanning result is temporary and short-lasting due to reaction with dead skin cells
Solution Approach 1:
The patent combines multiple self-tanning agents (dihydroxyacetone, erythrulose, and additional ketones) with vitamin D compounds and skin conditioning agents in a single composition. This merging of components creates a synergistic effect that extends the duration of action by providing both immediate tanning (from the ketones reacting with skin proteins) and prolonged maintenance (from the vitamin D compounds and conditioned skin), thereby resolving the contradiction between avoiding sunlight and achieving long-lasting tan results
2Shape
If self-tanning compositions are applied to achieve sun tan, then aesthetic appearance is improved, but the composition reacts only with dead skin cells causing temporary results
Solution Approach 1:
The patent employs a composite formulation containing multiple active ingredients (dihydroxyacetone, erythrulose, additional ketones) combined with vitamin D compounds and skin conditioning agents. This composite approach ensures that the tanning effect is not only aesthetically pleasing through the brown substance production but also long-lasting, as the combination of ingredients works at different rates and mechanisms to maintain the tan appearance over extended periods
3Duration of action of moving object
If sunlight exposure is increased to achieve sun tan, then tanning effect is enhanced, but skin damage, wrinkles, and cancer risk increase
Solution Approach 1:
The patent creates a chemical copy of the sun tan effect without requiring actual sunlight exposure. By applying dihydroxyacetone, erythrulose, and other ketones to the skin, the composition produces the same brown pigmentation and aesthetic effect as sunlight-induced tanning, while simultaneously providing skin conditioning benefits. This copying of the tanning effect eliminates the harmful UV radiation exposure while maintaining the desired aesthetic outcome
4Object-affected harmful factors
If sunscreen is applied to reduce sunburn risk, then skin protection is improved, but sun bathing duration is reduced
Solution Approach 1:
The patent extracts the tanning function from the sunlight exposure process and implements it through chemical application. By using dihydroxyacetone, erythrulose, and other ketones that react with skin proteins to produce brown substances, the composition provides sun tan without requiring UV exposure. This extraction of the tanning mechanism eliminates the need for sun bathing entirely, thereby removing both sunburn risk and time loss associated with sunscreen application
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 provides a longer-lasting, natural-looking sun tan by reacting with skin cells to produce a brown substance, offering improved tanning effects and skin care benefits while avoiding the risks associated with sunlight exposure.
Implementation Method 1
The self-tanner chemical reacts with proteins in the dead cells of the stratum corneum to produce a brown substance
Implementation Method 2
exposures of the skin to the ultraviolet portion, UVA in particular, of sunlight can cause the oxidation of the melanin pigment in the skin
Implementation Method 3
The oxidized melanin and increased amount of melanin in the skin cells offer protection against future exposures to sunlight by shielding the skin cell DNA from the harmful ultraviolet radiation of sunlight
