Cosmetic compositions with a lamellar network, comprising glycols, trihydric alcohols, cationic surfactants, alkoxylated fatty alcohols, and fatty alcohols, which transition from a solid-like to a liquid-like behavior upon heat or shear activation, offering improved viscosity changes and enhanced tactile experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conditioners are formulated to maintain stable emulsion over large temperature ranges, then reliability is improved, but the sensorial experience and tactile changes are reduced
Solution Approach 1:
The patent applies the dynamics principle by formulating a conditioner that transitions from a solid-like state at low temperatures to a liquid-like state at high temperatures. This dynamic behavior allows the product to maintain stability during storage (reliability) while providing tactile changes and sensorial experience during use. The phase transition is achieved through careful selection of oil phase components and emulsifiers that exhibit temperature-dependent rheological properties.
Solution Approach 2:
The patent directly applies phase transitions by designing a conditioner system that undergoes a sol-gel transition or melting transition in response to temperature changes. The composition includes specific ratios of oils, waxes, and emulsifiers that create a lamellar phase structure at room temperature (solid-like) which melts or reorganizes at body temperature or during application (liquid-like), providing both stability and sensorial benefits.
2Ease of manufacture
If conditioners are formulated with traditional emulsion structures, then ease of manufacture is improved, but the viscosity transition and tactile experience are reduced
Solution Approach 1:
The patent applies composite materials by combining multiple oil phase components (natural oils, synthetic esters, waxes) with specific emulsifiers to create a complex but stable system. This composite approach allows the formulation to exhibit temperature-dependent viscosity changes and tactile properties while maintaining relative ease of manufacture through conventional emulsion processing techniques.
3Manufacturing precision
If conditioners use conventional formulations, then manufacturing precision is improved, but the sensorial and tactile changes are reduced
Solution Approach 1:
The patent applies parameter changes by precisely controlling the composition ratios of oil phase components, emulsifiers, and other ingredients to achieve the desired temperature-dependent behavior. By adjusting parameters such as the type and amount of wax, oil composition, and emulsifier concentration, the formulation achieves consistent manufacturing while providing unique sensorial and tactile changes during use.
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 compositions provide a unique sensorial experience, effectively repairing hair damage by transitioning viscosity, reducing dryness, and improving hair health through a lamellar network structure that adapts to temperature changes, enhancing the repair of dry and damaged hair.
Implementation Method 1
the cosmetic compositions undergo a sensorial and/or tactile changes. For example, in some instances, the cosmetic compositions transition from exhibiting a more solid-like behavior to exhibiting a more liquid-like behavior in the presence of heat activation and/or shear
Implementation Method 2
the viscosity of the cosmetic composition may transition from a viscosity of about 10 to about 500 Pa·s at a temperature of 24° C. to a reduced viscosity of less than 100 Pa·s at a temperature of 40° C.
