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. 11,857,665.

Summary of the Inventive Concept

This inventive concept expands the application of a stable cosmetic ink composition to various industries, including bioprinting, personalized skin care, edible decorations, 3D printing of prosthetic limbs, and customized makeup products, enabling the creation of innovative products with unique properties.

Background and Problem Solved

The original patent described a stable cosmetic ink composition suitable for high-frequency printing via thermal and/or piezo inkjet printheads. However, its application was limited to traditional printing applications. This inventive concept addresses the need for a versatile ink composition that can be adapted to diverse industrial applications, overcoming the limitations of traditional printing inks.

Detailed Description of the Inventive Concept

The new inventive concept involves adapting the stable cosmetic ink composition to various industrial applications by modifying the particulate material, rheology modifier, and other components to suit specific requirements. For instance, in bioprinting, the ink composition can be optimized for printing living cells and biomaterials onto a substrate. In personalized skin care, the ink composition can be deposited onto a substrate to create customized skin care products. Similarly, the ink composition can be adapted for edible decorations, 3D printing of prosthetic limbs, and customized makeup products.

Novelty and Inventive Step

The new claims introduce novel applications and use cases for the cosmetic ink composition, which were not originally considered. The inventive step lies in the adaptation of the ink composition to diverse industrial applications, requiring modifications to the composition and its components.

Alternative Embodiments and Variations

Alternative embodiments of this inventive concept include using different types of particulate materials, modifying the rheology modifier, or incorporating additional components to enhance the ink composition's properties. Variations of the inventive concept can be explored by applying the cosmetic ink composition to other industries, such as pharmaceuticals, textiles, or food processing.

Potential Commercial Applications and Market

This inventive concept has significant commercial potential in various industries, including biotechnology, cosmetics, food, and healthcare. The target market includes companies and researchers involved in bioprinting, personalized skin care, edible decorations, 3D printing of prosthetic limbs, and customized makeup products, as well as other industries that can benefit from the versatility of the cosmetic ink composition.
