Biocellulose Microfibril Makeup Base for Deep Cleansing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current makeup cleansing methods using film-forming polymers and temperature-sensitive polymers are inefficient in removing makeup clogged in pores or wrinkles, leading to degraded cleansing effects and skin irritation.
Innovation Solution
A cosmetic composition containing biocellulose microfibrils with a number-average diameter of 30 to 60 nm and a maximum diameter of 60 to 100 nm, applied as a makeup base before color cosmetics, forms a physical film that detaches upon contact with water, enhancing makeup removal efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If film-forming polymers or temperature-sensitive polymers are used for makeup cleansing, then cleansing power is improved through structural changes when contacting water, but it is difficult to completely remove makeup clogged in pores or wrinkles and the cleansing effect may be degraded because the polymers fall off in small units
Solution Approach 1:
The invention uses biocellulose microfibrils with a specific diameter range (30-60 nm number-average, 60-100 nm maximum) that can penetrate into pores and wrinkles to segment and access clogged makeup, while the film-forming polymer provides structural integrity. This segmentation allows the composition to reach into small crevices without the entire film disintegrating.
Solution Approach 2:
The invention creates a composite material combining biocellulose microfibrils with film-forming polymers. The biocellulose provides penetration capability into pores and wrinkles, while the polymer matrix maintains film integrity and prevents disintegration during application and removal, achieving both deep cleansing and structural stability.
2Productivity
If cleansing products containing oily ingredients are used to remove hydrophobic makeup ingredients, then makeup removal effectiveness is improved, but skin irritation occurs due to the harsh cleansing process
Solution Approach 1:
The biocellulose microfibril-based film acts as an intermediary layer between the skin and the hydrophobic makeup. This intermediate film can be applied, allowed to set, and then removed with water, providing effective makeup removal without requiring harsh oily cleansers that irritate the skin.
Solution Approach 2:
The invention changes the parameter of film-detachment mechanism from chemical dissolution (using oily ingredients) to physical detachment (using water-soluble biocellulose). This parameter change allows the film to detach cleanly with water, avoiding skin irritation from harsh surfactants while maintaining effective makeup removal.
3Productivity
If biocellulose is applied to cosmetic formulations, then makeup cleansing power is improved due to desorption of film formed by application, but biocellulose is difficult to apply to cosmetic formulations and requires a complex dispersion process
Solution Approach 1:
The invention changes the parameter of biocellulose morphology to microfibrils with specific diameter dimensions (30-60 nm number-average, 60-100 nm maximum). This parameter change enables the biocellulose to be directly dispersed in aqueous cosmetic formulations without requiring complex chemical treatments, while maintaining the film-forming and cleansing properties.
