Peroxide Derivatives Microcapsule Delivery for Acne
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current acne treatments, including topical creams and oral medications, face challenges such as lack of precision in application, exposure of healthy skin to active ingredients, and adverse side effects like teratogenicity and irritations, necessitating a more effective and safer solution.
Innovation Solution
Development of novel peroxide derivatives with improved bactericidal activity against Propionibacterium acnes, while minimizing sensitizing and irritant effects, and providing anti-inflammatory benefits, as represented by specific compounds like (2-(Ethoxycarbonyloxy)benzoyl)benzoyl peroxide and bis(2-(ethoxycarbonyloxy)benzoyl)peroxide, which are synthesized through specific reaction schemes and tested for efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If topical formulations (creams, gels, emulsions, lotions) are used to treat acne, then the treatment can be applied to the skin, but the application lacks preciseness and exposes healthy skin to the active ingredients, causing irritation
Solution Approach 1:
The invention uses a microcapsule delivery system that segments the active ingredient (benzoyl peroxide) into individual encapsulated units. Each microcapsule contains a controlled amount of active ingredient, allowing precise delivery to the acne lesion site while preventing exposure of healthy surrounding skin. The microcapsules can be formulated in various topical vehicles (gels, creams, lotions) while maintaining their targeted delivery capability.
Solution Approach 2:
The microcapsule shell acts as an intermediary between the active ingredient and the skin. This intermediate structure protects healthy skin from direct contact with irritating active ingredients while allowing controlled release at the target site. The microcapsule formulation includes shell materials and internal phase components that mediate the delivery process.
2Reliability
If oral antiacne agents are administered, then severe acne cases can be treated, but numerous side effects occur including teratogenicity and gastrointestinal disturbances
Solution Approach 1:
The invention delivers the active ingredient locally to the acne lesion site rather than systemically throughout the body. The microcapsulated formulation is applied topically and targets specifically to affected areas, providing high local concentration where needed while avoiding systemic circulation that causes side effects like teratogenicity and gastrointestinal disturbances.
Solution Approach 2:
The invention extracts the harmful systemic effects by using topical microcapsulated delivery instead of oral administration. This removes the active ingredient from the systemic circulation pathway, eliminating exposure to vital organs while maintaining therapeutic effectiveness at the skin level.
3Productivity
If high concentrations of active ingredients are used in topical formulations, then antiacne effectiveness is improved, but irritation to normal skin increases
Solution Approach 1:
The invention changes the delivery parameters of the active ingredient by encapsulating it in microcapsules. This allows the formulation to maintain high effective concentration at the target site while controlling the release rate and spatial distribution. The microcapsule system transforms the delivery parameters from direct contact high concentration to controlled release localized concentration.
