Hair Cleansing Composition with Polyol Carrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clarifying shampoos effectively strip hair of natural moisturizers, leading to poor wet and dry hair feel, while traditional conditioners lack strong cleansing ability and leave residues, resulting in hair that feels greasy and difficult to style.
Innovation Solution
A deep cleansing hair care composition comprising 5-40% detersive surfactants, including linear and branched anionic surfactants, and a carrier with 20-80% polyols and 9-75% water, which provides superior cleansing, rich lather, and a clean rinse feel, while minimizing hair stripping and residue retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If clarifying shampoos are used to provide high level cleaning, then soil removal is improved, but natural moisturizers are stripped from hair resulting in poor wet and dry hair feel
Solution Approach 1:
The patent changes the chemical parameters of the shampoo by incorporating specific conditioning agents (cationic polymers, silicones, oils) and adjusting surfactant combinations to achieve a balance between cleansing power and moisture retention. This allows the product to remove soils effectively while preventing excessive stripping of natural hair moisturizers.
Solution Approach 2:
The patent creates a composite formulation by combining multiple ingredient types: detersive surfactants for cleaning, conditioning agents for moisture retention, and various additives for enhanced performance. This composite approach allows the shampoo to simultaneously achieve strong soil removal and maintain hair moisture balance.
2Object-affected harmful factors
If traditional conditioning shampoos are used to provide good wet and dry hair feel, then hair conditioning is improved, but cleansing ability is reduced resulting in residue accumulation on hair
Solution Approach 1:
The patent adjusts the concentration and type of conditioning agents to optimize the balance between conditioning performance and cleansing ability. By carefully controlling the parameters of cationic polymer content, silicone levels, and surfactant combinations, the shampoo provides good hair feel without compromising soil removal capability or causing excessive residue accumulation.
3Object-affected harmful factors
If conditioning agents are applied to improve wet and dry hair feel, then hair smoothness is improved, but hair volume is reduced resulting in greasy and difficult to style hair
Solution Approach 1:
The patent applies conditioning agents selectively to achieve local quality improvements on the hair surface while maintaining overall hair volume. The conditioning agents are formulated to coat the hair cuticle surface for smoothness without penetrating deeply or in excessive amounts that would weigh down the hair and reduce volume.
Solution Approach 2:
The patent optimizes the concentration and molecular weight parameters of conditioning agents to achieve the right balance between surface smoothness and volume maintenance. By adjusting these parameters, the shampoo provides hair smoothness without excessive conditioning that would cause hair to appear greasy and lose volume.
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 achieves thorough soil removal, enhancing hair volume, smoothness, and elasticity, resulting in bouncy, easy-to-style hair with a rich lather and clean rinse feel, while maintaining moisture and reducing dry hair friction.
Implementation Method 1
The hair care composition comprises from 5 to 40 weight % of the hair care composition one or more detersive surfactants
Data Source
AI summary
A shampoo composition is disclosed that has from about 5 to about 40 weight % of one or more detersive surfactants and an aqueous carrier comprising water and one or more polyols, wherein the weight ratio of one or more polyols to water is higher than or equal to about 0.4, and the water content is higher than or equal to about 9% by weight of the composition. The composition delivers thorough hair cleansing, good lather, good conditioning wet feel, clean rinse feel during use, leaving hair with very low residue on the hair surface. The use of the shampoo composition also provides high hair volume, smooth dry hair feel, and bouncy hair that is easy to style.
