Bile Acid Molecular Aggregates for Non-Invasive Fat Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fat-reducing treatments using deoxycholic acid require invasive injections, causing side effects and manufacturing challenges, and lack effective skin permeability for non-invasive fat reduction.
Innovation Solution
A cosmetic composition with a molecular association of bile acid or bile salt, formed through shear stress, is applied topically, with a pH above 8.5 and particle diameter of 1.0 to 10 nm, enhancing skin permeability and stability without the need for surfactants or carriers, allowing for localized fat reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If deoxycholic acid is administered via subcutaneous injection, then fat removal effect is achieved, but side effects such as pain, swelling, bruising, and nerve damage occur
Solution Approach 1:
The patent uses molecular associates as an intermediary carrier to deliver deoxycholic acid to the target site. These molecular associates protect the active ingredient during topical application, enabling controlled release and penetration through the skin barrier without requiring direct injection, thus eliminating injection-related side effects while maintaining fat removal efficacy
Solution Approach 2:
The patent replaces the mechanical injection system (needle and syringe) with a topical application system using molecular associates. This substitution eliminates the mechanical trauma caused by injections while achieving the same therapeutic effect through enhanced skin permeability and localized action of deoxycholic acid
2Reliability
If deoxycholic acid is formulated as injection, then fat cell destruction is achieved, but other cells may also die and anatomical knowledge is required for administration
Solution Approach 1:
Molecular associates serve as a selective delivery system that targets fat cells specifically. The amphiphilic structure of these associates enables them to accumulate in lipid-rich environments, ensuring that deoxycholic acid acts primarily on fat cells while sparing other cell types, and allowing non-specialists to administer the treatment safely
Solution Approach 2:
The molecular associates exhibit local concentration at the fat cell interface due to their amphiphilic properties. This localized accumulation ensures that the cytolytic action of deoxycholic acid is confined to fat cells where the associates concentrate, while surrounding tissues and other cell types remain unaffected
3Speed
If molecular association is formed with small particle diameter (1.0 to 10 nm), then skin permeability is enhanced, but manufacturing precision requirements increase
Solution Approach 1:
The patent optimizes the molecular associate formation parameters including pH (adjusted to 8.5-10), ionic strength, and mixing conditions to spontaneously generate particles within the 1.0-10 nm range. This parameter optimization enables consistent production of ultrafine particles with high skin permeability while maintaining manufacturing feasibility
Solution Approach 2:
The molecular associates form spontaneously through self-assembly of amphiphilic molecules under optimized conditions without requiring complex external control mechanisms. This self-organizing behavior simplifies the manufacturing process while ensuring consistent particle size distribution in the desired nanometer range

Data Source
AI summary
A cosmetic composition containing a molecular association of bile acid and bile salt is disclosed. The cosmetic composition contains a molecular association in which bile acid molecule or bile salt molecules are physically bonded, and when the molecular association is formed in a composition containing water, the molecular association has an associated structure in the composition.
