Supercritical CO2 Extracted Serenoa Repens Lipidosterolic Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current saw palmetto extracts for prostate and hair health face challenges in achieving consistent biological efficacy due to variations in fatty acid concentrations and ratios, leading to inefficiencies and high costs in quality control, and existing extraction methods fail to provide a standardized lipid profile that optimally balances free fatty acids and esters for specific health benefits.
Innovation Solution
A supercritical CO2 fluid-extracted, enhanced lipidosterolic extract of Serenoa repens with a high ratio of free fatty acids to total fatty acids (>80%) and enriched lauric, myristic, oleic, and linoleic acids, combined with linoleic and linolenic acids, is formulated to provide a stable and effective composition for prostate and hair health, formulated as a topical lotion or oral dosage form without added antioxidants or stabilizers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional extraction methods (hexane, ethanol) are used to isolate lipidosterolic extract, then the extract can be obtained, but harsh organic chemicals remain in the extract and the fatty acid concentrations vary widely
Solution Approach 1:
The patent changes the extraction parameters by using supercritical CO2 instead of conventional hexane or ethanol solvents. This parameter change eliminates harmful residual chemicals while providing consistent control over fatty acid concentrations through controlled pressure and temperature conditions during extraction.
Solution Approach 2:
The patent replaces the chemical extraction mechanism (using harsh organic solvents) with a physical extraction mechanism (supercritical fluid extraction using CO2). This substitution eliminates the harmful chemical residues while maintaining extraction efficiency and providing reproducible results.
2Reliability
If the fatty acid profile is not standardized, then the extract can be produced, but biological efficacy varies and quality control becomes complex and expensive
Solution Approach 1:
The patent establishes specific parameter ranges for fatty acid concentrations (e.g., 40-80% free fatty acids, specific ratios of lauric, myristic, oleic, and linoleic acids) during the extraction process. By controlling these parameters, the patent achieves standardized lipid profiles that ensure consistent biological efficacy while simplifying quality control through defined specifications.
3Quantity of substance
If free fatty acids are extracted without controlled conditions, then the extract can be obtained, but the ratio of free fatty acids to total fatty acids varies and bioavailability is reduced
Solution Approach 1:
The patent controls the extraction parameters (pressure, temperature, CO2 flow rate) to achieve a consistent ratio of free fatty acids to total fatty acids greater than 80%. This parameter control ensures reproducible lipid profiles with high free fatty acid content, maximizing bioavailability while maintaining ratio consistency across batches.

AI summary
A composition is formulated in a therapeutic amount to maintain and promote hair health and growth in a human in need thereof. The composition may comprise a shelf stable, supercritical CO2 fluid extracted, enhanced lipidosterolic extract of Serenoa repens (LSESr). The enhanced LSESr may have a ratio of free fatty acids to total fatty acids that is greater than about 80.0% and an enrichment of lauric, myristic, oleic and linoleic acids as free fatty acids to total free fatty acids that is greater than about 82.0%. An enrichment of linoleic and linolenic acids together may be greater than about 3.7%.
