Hair Shine Composition Using Polyether Siloxane Copolymer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hair care leave-on compositions that provide shine often result in a greasy or heavy feeling, and may dry out the scalp or hair due to high ethanol levels, which are used to achieve maximum refreshment and clean hair feel.
Innovation Solution
A hair care emulsion comprising a non-volatile polysiloxane fluid, a shining surfactant, a rheology modifier, and a carrier, with a surfactant mixture, specifically a polyether siloxane copolymer, to provide enhanced shine without greasiness or dryness, and a viscosity of less than 7 Pa*s, eliminating ethanol to prevent scalp drying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If leave-on compositions containing phenylated silicone and spreading agent are used to provide shine, then shine is improved, but hair feel becomes greasy and heavy
Solution Approach 1:
The invention extracts and removes phenylated silicone from the composition entirely, replacing it with non-phenylated alternatives. This eliminates the source of the greasy feeling while maintaining shine through different mechanisms (polyether siloxane copolymer surfactants and alternative conditioning agents), thus resolving the contradiction between shine and greasy feel.
Solution Approach 2:
The invention changes the chemical parameters of the silicone components by using non-phenylated polysiloxanes with specific viscosity ranges and incorporating polyether siloxane copolymers with controlled HLB values. These parameter changes alter the interaction with hair and skin, providing shine without the greasy sensation associated with phenylated silicones.
2Ease of operation
If high levels of ethanol are used to provide refreshment and clean hair feel, then clean hair feel is improved, but scalp and hair become dry
Solution Approach 1:
The invention completely removes ethanol from the composition formulation. Instead of relying on ethanol for clean feel and refreshment, it uses alternative ingredients such as polyether siloxane copolymer surfactants and volatile silicones that provide similar sensory benefits without the drying side effects, thus eliminating the trade-off between clean feel and dryness.
Solution Approach 2:
The invention uses volatile silicones (such as cyclomethicone) that evaporate quickly from the hair and scalp, providing temporary refreshment and clean feel similar to ethanol but without the harmful drying effects. These volatile components serve their purpose and then disappear, leaving no residual dryness.
3Illumination intensity
If phenylated silicone and spreading agent combination is used to improve shine, then shine is enhanced, but hair becomes coated and feels unwashed
Solution Approach 1:
The invention removes phenylated silicone and the specific spreading agent combination that causes coating. It replaces them with non-phenylated polysiloxanes and polyether siloxane copolymer surfactants that provide shine through different mechanisms, preventing the formation of a coated feeling while maintaining lustrous appearance.
Solution Approach 2:
The invention uses a composite approach combining multiple ingredients (non-phenylated polysiloxanes, polyether siloxane copolymer surfactants, rheology modifiers) that work synergistically to provide shine without coating. The combination creates a different film formation mechanism on the hair that avoids the unwashed feeling associated with phenylated silicone formulations.
