Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic compositions with antioxidants are unstable, leading to inactivation before reaching the target, and there is a need for stable formulations that can effectively prevent oxidative stress and aging through sustained antioxidant activity.
Innovation Solution
A stable cosmetic formulation combining green tea extract with additional active agents like aroeira, coffee, vitamin E, grape seed oligomeric proanthocyanidins, cocoa, Castanea sativa seed extract, and soybean protein, along with cosmetically acceptable carriers and accessory ingredients, to provide sustained antioxidant effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antioxidants are used in cosmetic formulations to prevent oxidative stress and aging, then antioxidant activity is improved, but product stability deteriorates because antioxidants are generally unstable and can be oxidized and inactivated before reaching the target
Solution Approach 1:
The patent combines multiple antioxidants (vitamin C, vitamin E, ferulic acid, resveratrol, green tea extract) into a single formulation. This synergistic combination allows each antioxidant to support and protect the others, maintaining both high antioxidant activity and improved product stability. The antioxidants work together to neutralize free radicals while being protected from premature oxidation by the collective presence of multiple protective agents.
Solution Approach 2:
The invention creates a composite antioxidant system by formulating a mixture of different antioxidant compounds with complementary properties. This composite approach allows the formulation to maintain stability through diverse chemical mechanisms while delivering sustained antioxidant activity. The composite material strategy enables the product to resist oxidation through multiple pathways simultaneously.
2Reliability
If antioxidants are used to neutralize free radicals in skin products, then prevention of clinical signs of aging is improved, but the antioxidants can be oxidized and inactivated before reaching the target tissue
Solution Approach 1:
The formulation is designed with antioxidants that are pre-positioned and stabilized in the cosmetic product before application. The antioxidants are incorporated into the formulation matrix in advance, protected from degradation during storage and application. This preliminary stabilization ensures that active antioxidant compounds are delivered to the target tissue in their effective form, preventing oxidation before the antioxidants reach the skin.
3Duration of action of moving object
If the product should remain on the skin to reach the target tissue in active form, then duration of action is improved, but antioxidants may be oxidized during this period
Solution Approach 1:
The patent employs multiple antioxidants with different kinetic profiles and mechanisms of action that work continuously and complementarily. As some antioxidants are consumed or oxidized, others continue to provide protection. This continuous multi-layered antioxidant defense ensures sustained protection over time while the product remains on the skin, with the antioxidant system self-replenishing through the synergistic interaction of its components.
