Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Natural antibacterial agents like hops in oral care compositions face solubility issues, leading to phase separation and uneven distribution, affecting shelf-stability and efficacy.
Innovation Solution
Incorporating surfactants such as sodium lauryl sulfate, cocamidopropyl betaine, sodium cocoyl glutamate, sodium methyl cocoyl taurate, and poloxamer with hops beta acids to enhance solubility and stability, ensuring a clear or slightly hazy solution within a pH range of 4.5 to 9.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hops are incorporated into oral care compositions to provide antibacterial activity, then antibacterial efficacy is improved, but solubility deteriorates leading to phase separation
Solution Approach 1:
The patent introduces surfactants as intermediary substances that mediate between the hydrophobic hops beta acids and the aqueous oral care composition. The surfactants act as solubilizing agents, forming micelles that encapsulate the hops beta acids and allow them to be dispersed in water-based formulations, thereby preventing phase separation while maintaining antibacterial efficacy.
Solution Approach 2:
The patent modifies the physical-chemical parameters of the hops beta acids through formulation adjustments, specifically by changing the pH level (optimizing for pH 7-9) and incorporating co-surfactants. These parameter changes enhance the solubility and stability of hops in the oral care composition, preventing aggregation and phase separation.
2Reliability
If hops are incorporated into oral care compositions to provide antibacterial activity, then antibacterial efficacy is improved, but shelf-stability deteriorates due to phase separation
Solution Approach 1:
Surfactants serve as stabilizing intermediaries that maintain homogeneous distribution of hops beta acids throughout the product shelf life. By forming stable micellar structures and preventing aggregation, the surfactants ensure that hops remain uniformly dispersed and active throughout the product duration, preventing phase separation and maintaining shelf-stability.
Solution Approach 2:
The patent creates a composite formulation combining hops beta acids with specific surfactant systems (anionic, nonionic, and amphoteric surfactants). This composite approach synergistically enhances both the antibacterial activity and shelf-stability of the composition, with the surfactant-hops complex remaining stable throughout the product lifecycle.
3Reliability
If hops are incorporated into oral care compositions, then antibacterial activity is improved, but uniform distribution deteriorates due to phase separation
Solution Approach 1:
Surfactants act as distributing intermediaries that ensure uniform dispersion of hops beta acids throughout the oral care composition. The surfactant molecules distribute the hydrophobic hops evenly in the aqueous matrix through micelle formation, preventing localized aggregation and ensuring consistent antibacterial activity across the entire product.

AI summary
An oral care composition includes hops and one or more surfactants. A solution including the hops and the one or more surfactants is clear or slightly hazy in a pH range of about 4.5 to about 9. If the one or more surfactants include sodium cocoyl glutamate, lauryl glucoside, or poloxamer, then the oral care composition includes at least two surfactants.
