Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair drying compositions form coatings that increase drying time and are not resistant to shampoo washing, failing to efficiently reduce hair drying time without leaving residues.
Innovation Solution
A silicone-free composition comprising a volatile hydrocarbon mixture, emollients, and thermal protectants, applied to wet hair to remove up to 100% of added water, reducing drying time by 20-30% and providing thermal protection without leaving residues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing hair drying compositions are applied to wet hair, then they form coatings on hair, but this makes hair less water repellent and increases drying time
Solution Approach 1:
The invention changes the chemical composition parameters by using a specific volatile hydrocarbon mixture (C13-C16 isoparaffin, C12-C14 isoparaffin, C13-C15 alkane) with controlled volatility and water repellency properties, replacing traditional silicone-based coatings to achieve faster drying while maintaining wash resistance
Solution Approach 2:
The invention creates a composite formulation combining volatile hydrocarbons with specific emollients (ppg-3 benzyl ether myristate) and polymers (sodium laneth 40-maleate/styrene sulfonate copolymer) to achieve synergistic effects of rapid evaporation, water repellency, and coating stability through multiple washing cycles
2Loss of time
If existing compositions are applied to reduce drying time, then they may decrease drying time, but they leave residues on clean hair and are degraded rapidly by shampoo
Solution Approach 1:
The invention optimizes the volatility parameter of the hydrocarbon mixture to ensure complete evaporation during drying, eliminating residues while maintaining rapid drying performance. The specific carbon chain lengths (C12-C16) are selected to balance evaporation rate and wash resistance
Solution Approach 2:
The volatile hydrocarbon composition acts as a temporary, short-lived agent that performs its function rapidly during drying then completely evaporates or washes away without leaving persistent residues, replacing long-lasting coating formulations
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 composition effectively reduces hair drying time by 20-30% while maintaining thermal protection and resistance to shampoo washing, without leaving residues on clean hair.
Implementation Method 1
a volatile hydrocarbon mixture comprising C13-C16 isoparaffin, C12-C14 isoparaffin; and C13-C15 alkane
Implementation Method 2
about 0.01 to about 0.5 percent by weight of an emollient mixture comprising isostearic acid, sorbitan oleate, cocoyl hydrolyzed keratin and heat to wet hair, thereby removing from about 85% to about 100% of added water

AI summary
A composition and method for reducing the drying time of wet hair by about 20 to about 30 percent includes applying a silicone-free, non-aqueous composition comprising about 90 to about 96 percent by weight of a volatile hydrocarbon mixture comprising C13-C16 isoparaffin, C12-C14 isoparaffin; and C13-C15 alkane; about 2 to about 3 percent by weight of ppg-3 benzyl ether myristate; about 0.001 to about 0.01 percent by weight of a sodium laneth 40-maleate/styrene sulfonate copolymer; and about 0.01 to about 0.5 percent by weight of an emollient mixture comprising isostearic acid, sorbitan oleate, cocoyl hydrolyzed keratin and heat to wet hair, thereby removing from about 85% to about 100% of water added to the hair during washing.
