Adaptable Cosmetic Ink Compositions for Specialized Applications

This inventive concept discloses a series of specialized cosmetic ink compositions tailored for high-security, disaster relief, and extreme weather conditions, offering improved performance and reliability in these unique environments.

The original patent provided a stable cosmetic ink composition suitable for general printing applications. However, these inks may not meet the specific demands of high-security, disaster relief, or extreme weather conditions. The new inventive concept addresses these limitations by adapting the original composition to these niche markets, ensuring optimal performance and reliability.

The inventive concept comprises a range of cosmetic ink compositions, each optimized for a specific application. For high-security applications, the ink composition features a particulate material with a Particle Size Distribution D50 of about 100 nm to about 2,000 nm, and a (meth)acrylic acid homopolymer or salt thereof with a ratio of at least 5:1 to the rheology modifier, exhibiting a storage modulus of at least 100 Pa at 20°C and 50% RH. For disaster relief applications, the ink composition has a ratio of at least 10:1, with a storage modulus of at least 500 Pa at 20°C and 50% RH. For extreme weather conditions, the ink composition features a particulate material with a Particle Size Distribution D50 of about 100 nm to about 2,000 nm, and a (meth)acrylic acid homopolymer or salt thereof with a ratio of at least 5:1 to the rheology modifier, and is jetted through a piezo printhead at a frequency of at least 5 kHz.

The new claims introduce specific adaptations to the original composition, including tailored ratios of (meth)acrylic acid homopolymer or salt thereof to rheology modifier, and optimized storage moduli, which provide improved performance and reliability in high-security, disaster relief, and extreme weather conditions. These adaptations are non-obvious and novel compared to the original patent.

Alternative embodiments of the inventive concept could include varying the type of particulate material, modifying the rheology modifier, or adjusting the printhead configuration to further optimize performance in specific applications.

The inventive concept has significant commercial potential in the high-security, disaster relief, and extreme weather conditions markets, where reliable and high-performance cosmetic ink compositions are essential. Target industries include security printing, disaster relief organizations, and manufacturers operating in extreme weather conditions.
