Enhanced Rinse-off Conditioner Compositions with Microcapsules

The inventive concept presents novel rinse-off conditioner compositions and methods that improve the deposition efficiency of microcapsules on a substrate, enhancing the overall conditioning performance and fragrance release.

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, the original composition had limitations in terms of deposition efficiency of the microcapsules on a substrate, which affected the overall conditioning performance and fragrance release. The new inventive concept addresses these limitations by introducing novel compositions and methods that improve the deposition efficiency of the microcapsules.

The inventive concept comprises four novel compositions and two methods that enhance the deposition efficiency of microcapsules on a substrate. The first composition adds a humectant and an emollient in a ratio of 1:1 to 1:5, improving the deposition efficiency of the microcapsules. The second composition combines a non-quaternized conditioning ingredient and a water-soluble cationic conditioning polymer in a ratio of 2:1 to 5:1, enhancing the deposition efficiency. The third composition includes a chelating agent in an amount of 0.1 to 2 wt%, improving the stability of the microcapsules in the composition. The fourth composition is a method for enhancing the olfactive performance of a fragrance by adjusting the pH of the composition to a range of 4.5 to 5.5. The two methods involve applying a mechanical stress to the composition and adjusting the pH to improve the deposition efficiency of the microcapsules.

The new inventive concept introduces novel compositions and methods that improve the deposition efficiency of microcapsules on a substrate, which is not disclosed in the original patent. The addition of a humectant and an emollient, the combination of a non-quaternized conditioning ingredient and a water-soluble cationic conditioning polymer, the inclusion of a chelating agent, and the adjustment of pH and application of mechanical stress are all new and non-obvious features that enhance the conditioning performance and fragrance release.

Alternative embodiments of the inventive concept could include varying the ratio of humectant and emollient, using different types of non-quaternized conditioning ingredients and water-soluble cationic conditioning polymers, and adjusting the amount of chelating agent. Additionally, the methods could be modified to use different types of mechanical stress or pH adjustment techniques.

The inventive concept has significant commercial potential in the personal care industry, particularly in the development of rinse-off conditioner products with improved conditioning performance and fragrance release. The target market includes manufacturers of hair care products, cosmetic companies, and consumers seeking high-performance conditioning products.
