TAS Hair Conditioner Composition for Smoothness Without Buildup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hair conditioners based on cationic surfactants and fatty alcohols build up on the hair, leading to a loss of smoothness and manageability, and there is a need for a composition that provides hair smoothness without buildup.
Innovation Solution
A composition comprising tertiary amidoamine surfactants, beta hydroxy acids, and optionally C16-C22 fatty alcohols, with a molar ratio of 1:1 to 1:0.01 and a pH of at least 6.5, forming a denser lamellar structure that provides hair smoothness without buildup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional cationic surfactants and fatty alcohols are used in hair conditioners, then hair smoothness is provided, but buildup on hair occurs leading to loss of smoothness and manageability
Solution Approach 1:
The patent changes the chemical parameters by using tertiary amidoamine surfactants instead of conventional cationic surfactants, and controls the molar ratio between surfactant and beta-hydroxy acid (1:1 to 1:0.01) to achieve smoothness without buildup. The pH is also adjusted to at least 6.5 to optimize performance
Solution Approach 2:
The invention creates a composite formulation combining tertiary amidoamine surfactants with beta-hydroxy acids in specific proportions, forming a gel-network structure that provides conditioning benefits while preventing buildup. This composite approach allows the system to deliver smoothness without the adverse effects of conventional formulations
2Stability of the object's composition
If fatty alcohols are included in the composition, then composition stability is improved, but buildup on hair increases
Solution Approach 1:
The patent strictly limits the fatty alcohol content to less than 1 wt.% and preferably excludes it entirely, while compensating for stability through the gel-network structure formed by the tertiary amidoamine surfactant and beta-hydroxy acid combination. This parameter change eliminates buildup while maintaining stability through alternative mechanisms
Solution Approach 2:
The beta-hydroxy acid acts as an intermediary that works synergistically with the tertiary amidoamine surfactant to provide composition stability without requiring high levels of fatty alcohols. This mediator enables the system to achieve both stability and low buildup

AI summary
A composition for conditioning the hair comprises: a) at least one tertiary amidoamine surfactant; b) at least one beta hydroxy acid; and c) optionally a C16-C22 fatty alcohol, wherein the molar ratio of the tertiary amidoamine surfactant to the beta hydroxy acid is from 1:1 to 1:0.01, the pH of the composition is at least 6.5, if presents, the total amount of the C16-C22 fatty alcohol is lower than lwt. %.
