Anhydrous Polysiloxane Serum for Frizz Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair care products fail to effectively control frizz, particularly in high humidity conditions, and often result in an unnatural feel or greasiness, with many users seeking high-performance, leave-in formulations that are manageable and natural-looking.
Innovation Solution
Compositions comprising at least 2% by weight of polysiloxane fluid components such as alkoxytetramethyl piperidinyl dimethicone, propoxytetramethyl piperidinyl dimethicone, trimethylsilyl siloxane, or aminopropyl siloxane, combined with a silicone-compatible, volatile liquid carrier, which are applied to hair to reduce frizz and enhance curl memory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If natural oils and fats are used to control frizz, then frizz control is improved, but the hair looks wet and greasy
Solution Approach 1:
The patent changes the chemical parameters of the conditioning agents by using modified silicones with specific molecular weights, viscosity ranges, and functional group compositions. These parameter adjustments allow the product to control frizz through moisture regulation rather than oil-based coating, eliminating the greasy appearance while maintaining frizz control effectiveness.
Solution Approach 2:
The invention uses composite silicone formulations combining multiple silicones with different properties (hydrophobic silicones for moisture barrier, volatile silicones for light texture, amino-functionalized silicones for conditioning). This composite approach achieves frizz control without the greasiness of natural oils by distributing functionality across multiple synthetic components.
2Strength
If styling products with organic styling resins are used, then hair hold is improved, but the hair feels unnatural and stiff
Solution Approach 1:
The patent modifies the physical parameters of styling agents by using silicones with controlled viscosity (500-50,000 cP) and molecular weight. These parameter changes enable the product to provide hold through flexible film formation rather than rigid resin coating, maintaining natural feel while achieving styling effectiveness.
Solution Approach 2:
The invention replaces organic styling resins (mechanical/chemical crosslinking agents) with silicone-based polymers that provide hold through physical film formation and moisture control. This substitution eliminates the stiff, unnatural feel associated with traditional styling resins while maintaining hair hold capability.
3Ease of operation
If water and alcohol-based products with fatty quaternary ammonium components are used, then combing and styling are improved, but the product distribution and natural feel are compromised
Solution Approach 1:
The patent changes the chemical composition parameters by replacing fatty quaternary ammonium components with amino-functionalized silicones and other silicone derivatives. These parameter changes maintain the conditioning and combing benefits while improving product distribution through the volatile carrier system and restoring natural feel by eliminating heavy fatty components.
Solution Approach 2:
The invention uses volatile silicones (cyclomethicone, dimethicone) as intermediary carriers that facilitate even product distribution through the hair. These volatile intermediaries evaporate after application, leaving behind the active conditioning silicones without the greasy residue associated with fatty quaternary ammonium components, thus improving both distribution and natural feel.
4Reliability
If alcohol-based serums with volatile components are used to dehydrate hair cortex, then frizz control is improved, but the hair may feel dry and unnatural
Solution Approach 1:
The patent adjusts the dehydration mechanism by using hydrophobic silicones with controlled molecular weight and viscosity rather than alcohol-based volatile components. These parameter changes allow moisture removal from the cortex to occur through hydrophobic interaction rather than aggressive dehydration, maintaining frizz control while preserving natural hair feel and preventing excessive dryness.

AI summary
Methods and compositions for preventing or reducing hair frizz. The compositions are anhydrous and comprise at least one polysiloxane fluid component selected from an amodimethicone and a polysiloxane component comprising a plurality of hindered amine side chains. The compositions also comprise a silicone-compatible, volatile liquid carrier component, preferably selected from a low molecular weight, volatile siloxy component; a hydrocarbon; and an alcohol. The compositions are preferably serums or fluids, and are suitable for use in a conditioner, as a “leave-in” hair care product, or as a touch-up hair care product suitable for use during the day.
