Low-Silicone Hair Composition With Dual Cationic Polysaccharides
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair care compositions with high silicone contents provide insufficient and short-lasting cosmetic benefits, leading to issues like difficulty in disentangling, lack of softness, and rapid loss of smoothness, while high silicone use is also unfavorable to consumers.
Innovation Solution
A cosmetic composition comprising low silicone content with a weight ratio of cationic surfactants to silicones greater than or equal to 7, including at least two different cationic surfactants, anionic and/or amphoteric surfactants, and one or more silicones, which provides long-lasting care and repair benefits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high silicone content is used in hair care compositions, then initial cosmetic benefits such as smoothness and disentangling are improved, but the duration of these benefits is short and the effects diminish rapidly over time
Solution Approach 1:
The patent combines multiple cationic surfactants with different functions (conditioning, repair, protection) and different silicones (amino silicones, non-amino silicones, volatile and non-volatile) to create a composite formulation. This composite approach allows the composition to provide both immediate cosmetic benefits and long-lasting effects, resolving the contradiction between initial effectiveness and duration of action.
Solution Approach 2:
The patent specifies precise parameter ranges: cationic surfactants at 0.1-10% wt, silicones at 0.01-5% wt with a weight ratio of at least 7:1, and particular amino silicone content of 0.01-2% wt. These optimized parameters ensure long-lasting cosmetic benefits (at least 24 hours) while maintaining lightness and cleanliness, overcoming the limitation of high silicone formulations that provide only short-term benefits.
2Reliability
If high silicone content is used to provide care and repair benefits, then cosmetic properties are improved, but the hair feels lank and the composition is unfavorable to consumers
Solution Approach 1:
The patent optimizes the silicone content to 0.01-5% wt with a weight ratio of cationic surfactants to silicones of at least 7:1, which is significantly lower than conventional high silicone formulations. This parameter change provides effective care and repair benefits while avoiding the lank feel that consumers find unfavorable, thus improving consumer acceptance.
Solution Approach 2:
The formulation uses a composite of multiple cationic surfactants (including amino surfactants, quaternary ammonium salts, and fatty amine derivatives) combined with low levels of silicones. This composite material approach delivers effective hair care and repair while maintaining a clean, non-lank feel that consumers prefer.
3Duration of action of moving object
If multiple cationic surfactants are used to achieve long-lasting care effects, then the cosmetic performance is improved, but the formulation complexity increases
Solution Approach 1:
The patent combines multiple cationic surfactants with complementary functions: amino surfactants for conditioning and repair, quaternary ammonium salts for anti-static and detangling properties, and fatty amine derivatives for softness. This composite approach achieves long-lasting care effects (at least 24 hours) while maintaining a balanced formulation that is not excessively complex.
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 offers easy rinsing, long-lasting care effects such as improved disentangling, smoothness, suppleness, and end repair, maintaining a clean feel for at least 24 hours without a lank feel, even after shampooing.
Implementation Method 1
The hair is sensitive to many types of attack and can be embrittled and damaged... The properties of damaged hair are then degraded... cosmetic composition comprising one or more surfactants chosen from anionic surfactants and amphoteric surfactants, at least two cationic surfactants different from one another
Implementation Method 2
These compositions are generally based on the use of high contents of silicones and offer benefits... cosmetic composition comprising low silicone contents... one or more silicones, the weight ratio between the total content of cationic surfactants and the total content of silicone(s) being greater than or equal to 7
