Cosmetic Brush Cleaner Formulation for Quick Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cosmetic brushes face issues with moisture retention leading to microbial growth, stickiness from surfactants, and deformation, making them difficult to use and apply cosmetics effectively, while traditional drying methods can damage the bristles and are time-consuming.
Innovation Solution
A cosmetic brush cleaner comprising 30-99% lower alcohol, 1-70% volatile oil, and up to 7% water, which can be impregnated into tissue or sprayed onto the brush, allowing for easy stain removal and quick drying without surfactants, preventing stickiness and bristle damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If water or lukewarm water is used to clean the cosmetic brush, then stains such as cosmetics and sebum can be removed, but moisture remains in the bristle tufts leading to microbial growth and offensive smell
Solution Approach 1:
The patent changes the chemical composition parameters of the cleaning liquid by formulating a spray solution containing alcohol (30-95 mass%), volatile oil (5-70 mass%), and water (0-20 mass%). This parameter change allows the cleaning liquid to evaporate quickly while maintaining effective cleaning properties, thus preventing microbial growth and offensive smell caused by moisture retention.
Solution Approach 2:
The patent replaces the traditional mechanical drying process with a chemical evaporation mechanism. By using a specially formulated spray solution with high alcohol and volatile oil content, the liquid naturally evaporates quickly without requiring external mechanical drying, thereby preventing moisture-related problems while maintaining cleaning effectiveness.
2Loss of time
If hot air is blown to the bristle tufts using a dryer to speed up drying, then drying time is reduced, but the bristle tufts are damaged and lose soft touch
Solution Approach 1:
The patent changes the physical parameters of the cleaning liquid by formulating it with high alcohol (30-95 mass%) and volatile oil (5-70 mass%) content. These components have high volatility and low evaporation temperature, allowing the liquid to evaporate quickly at room temperature without requiring high-temperature hot air drying, thus preserving bristle integrity and soft touch while reducing drying time.
Solution Approach 2:
The patent replaces the mechanical hot air drying system with a chemical evaporation system. The specially formulated spray solution containing alcohol and volatile oil evaporates naturally through its own volatility properties, eliminating the need for external hot air mechanical drying that damages bristles, while achieving quick drying results.
3Ease of manufacture
If neutral detergent is used to clean the cosmetic brush, then stains can be removed, but surfactant remains in the bristle tufts making them sticky
Solution Approach 1:
The patent extracts and eliminates the harmful surfactant component from traditional neutral detergent formulations. By replacing surfactants with alcohol (30-95 mass%) and volatile oil (5-70 mass%), the invention removes the sticky residue problem while maintaining effective cleaning capability for cosmetics and sebum stains.
Solution Approach 2:
The patent changes the chemical composition parameters by substituting surfactants with alcohol and volatile oil in the cleaning liquid formulation. This parameter change maintains the cleaning effectiveness for removing stains while eliminating the sticky residue that surfactants leave in the bristle tufts, thus preventing stickiness.
4Ease of operation
If the brush is left to stand in an inappropriate state after cleaning, then no additional drying effort is needed, but the bristle tufts become bent or twisted resulting in deformation
Solution Approach 1:
The patent replaces the need for mechanical positioning and support structures during drying with a chemical evaporation mechanism. The spray solution containing alcohol and volatile oil evaporates quickly through its own volatility, eliminating the requirement for upright positioning or support structures, thus preventing bristle deformation while maintaining operational simplicity.
Solution Approach 2:
The patent changes the evaporation time parameter by formulating the cleaning liquid with high alcohol (30-95 mass%) and volatile oil (5-70 mass%) content. This parameter change reduces the drying time so significantly that the bristles do not remain in any particular position long enough to deform, eliminating the need for careful positioning while preventing shape distortion.

Function Achieved in This Case
The cleaner effectively removes cosmetics and sebum from brushes, prevents stickiness, and ensures quick dryability, maintaining the brush's softness and effectiveness, eliminating the need for prolonged drying processes.
Implementation Method 1
by mixing a lower alcohol, a volatile oil, and water each in a predetermined amount, it is possible to obtain a cosmetic brush cleaner capable of removing the stains such as cosmetics deposited on a cosmetic brush with ease, and further, also excellent in quick dryability
