Fermented Vegetable Oil Skin Flora Metabolites
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vegetable oils, despite containing beneficial active substances for the skin, face challenges in absorption and have characteristics like a heavy oil feeling and unique odor, limiting their use in cosmetics.
Innovation Solution
A cosmetic composition is developed by fermenting vegetable oil with skin flora, specifically using microorganisms like Epidermidibacterium keratini sp., to enhance skin affinity and absorption, thereby providing a skin barrier-protecting effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vegetable oil is used directly in cosmetics, then it contains beneficial active substances for the skin, but it has poor skin absorption and causes heavy oil feeling and unique odor
Solution Approach 1:
The patent applies parameter changes by fermenting vegetable oil with skin flora to alter its chemical composition. The fermentation process increases the polarity of lipid components and generates metabolites that improve skin absorption while maintaining the beneficial active substances. This transforms the oil's properties to resolve the contradiction between providing skin barrier protection and achieving good skin absorption.
2Reliability
If vegetable oil is used directly in cosmetics, then it contains beneficial active substances for the skin, but it has poor skin absorption and causes heavy oil feeling and unique odor
Solution Approach 1:
The fermentation process changes the chemical parameters of vegetable oil, increasing polarity of lipid components and generating skin-friendly metabolites. This transformation reduces the heavy oil feeling and unique odor while preserving the skin barrier protection benefits.
Solution Approach 2:
The patent uses skin flora as an intermediary to transform vegetable oil. The microorganisms ferment the oil and produce metabolites that serve as a bridge between the original vegetable oil and the skin, improving compatibility and reducing harmful sensory effects like heavy feeling and odor.
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 fermentation process improves skin absorption and adhesion of vegetable oil, leading to enhanced skin barrier protection and improved skin health, with increased polarity of lipid components contributing to better skin absorption and emulsion stability.
Implementation Method 1
a seed culture step of producing a seed culture by culturing microorganisms with deposit number of KCCM 11843P as skin flora; a preculture step of culturing the seed culture to produce a preculture; and a main fermentation step of producing a fermented product by adding the preculture to a medium containing vegetable oil
