Enhanced Isotropic Concentrate and Wash Compositions
Legal Citation
Summary of the Inventive Concept
An improved isotropic concentrate composition that offers enhanced sensory benefits, improved dispensability, and increased stability, resulting in a superior wash composition for topical application and hand washing.
Background and Problem Solved
The original patent disclosed an isotropic concentrate composition suitable for topical application and hand washing. However, it had limitations in terms of sensory benefits, dispensability, and stability. The new inventive concept addresses these limitations by introducing a system that combines anionic and amphoteric surfactants, adjusts viscosity for improved dispensability, incorporates humectants for enhanced moisturizing, and utilizes stabilizing agents for increased shelf life.
Detailed Description of the Inventive Concept
The enhanced isotropic concentrate composition comprises a mixture of anionic surfactants and amphoteric surfactants, which provides improved sensory benefits. The composition's viscosity can be adjusted to a range from 0.0 to 650 cps, making it suitable for pump dispensers. Additionally, the incorporation of humectants in an amount from 10 to 40% by weight enhances the moisturizing properties of the wash composition. The system also includes a stabilizing agent present in an amount from 0.1 to 5% by weight, ensuring improved shelf life. The new claims provide a more efficient, safer, and more efficient wash composition.
Novelty and Inventive Step
The new claims introduce a novel combination of anionic and amphoteric surfactants, viscosity adjustment, and incorporation of humectants and stabilizing agents, which provides a non-obvious solution to the limitations of the original patent.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept could include varying the ratio of anionic to amphoteric surfactants, using different types of humectants, or incorporating additional ingredients to enhance the wash composition's performance. Variations could also include adjusting the pH range or incorporating different types of stabilizing agents.
Potential Commercial Applications and Market
The enhanced isotropic concentrate composition has significant commercial potential in the personal care industry, particularly in the hand wash and body wash markets. The improved sensory benefits, dispensability, and stability make it an attractive solution for manufacturers seeking to differentiate their products and improve customer satisfaction.
