This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,659.

Summary of the Inventive Concept

The inventive concept relates to rinse-off conditioner compositions adapted for specific, narrow market or unique operational environments, such as high-altitude, arctic, disaster relief, high-security, and extreme weather conditions.

Background and Problem Solved

The original patent disclosed rinse-off conditioner compositions comprising microcapsules with an oil-based core and a polymeric shell coated with at least one cationic polymer. However, these compositions may not be suitable for specific environments where extreme temperatures, low air pressure, or other challenging conditions are present. The new inventive concept addresses this limitation by providing specialized rinse-off conditioner compositions tailored to these unique environments.

Detailed Description of the Inventive Concept

The inventive concept comprises rinse-off conditioner compositions with microcapsules specifically designed to withstand low air pressure, extreme temperature fluctuations, and other environmental stressors. The compositions may include specialized waxes, oils, or conditioning ingredients to maintain structural integrity and provide enhanced moisturizing properties. The microcapsules are coated with a polymeric shell comprising at least one cationic polymer, and the compositions may include up to 4 wt % by weight of at least one quaternary ammonium salt and from 0.25 to 15 wt % by weight of at least one non-quaternized conditioning ingredient.

Novelty and Inventive Step

The new inventive concept provides a novel and non-obvious solution by adapting the original rinse-off conditioner compositions to specific, narrow market or unique operational environments. The specialized microcapsules and conditioning ingredients provide enhanced performance and stability in these environments, which is not achievable with the original compositions.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include varying the type and amount of specialized waxes, oils, or conditioning ingredients to optimize performance in different environments. Additionally, the compositions may be packaged in compact, portable units for easy transportation and use in emergency situations.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in various industries, including cosmetics, personal care, and disaster relief. The specialized rinse-off conditioner compositions can be marketed to consumers and professionals operating in high-altitude, arctic, or extreme weather environments, as well as to organizations involved in disaster relief and high-security operations.
