High-Temperature Expandable Graphite for Engineering Polymers
High Temperature Expandable Graphite from LUH is able to be used in thermoplastics without expanding during the extrusion process.
In the ever-evolving world of cosmetics, the quest for vibrant, eye-catching colours that are both ethically sourced and environmentally friendly has led to significant innovations in pigment technology. GEOTECH’s latest offer, the Geopearl® C Crystal Super Deep Pink and Purple pigments, represents a leap forward in combining high-impact colour with a commitment to cruelty-free and vegan product formulations.
Traditionally, carmine has been a popular choice for achieving deep red and pink hues in cosmetics. Derived from cochineal insects, its use raises ethical concerns and poses a significant barrier for vegan and cruelty-free products. In response, GEOTECH's development of these carmine-free pigments, offers a compelling alternative. These pigments are not only free from animal-derived ingredients but also align with the increasing demand for ethical and sustainable beauty products.

The Geopearl® C Crystal pigments utilize synthetic mica coated with titanium dioxide, iron oxide, and other compounds to produce their intense colours. Unlike natural mica, synthetic mica offers greater purity and consistency, resulting in brighter and more uniform colours. This innovative approach ensures that the Super Deep Pink and Purple pigments provide unmatched vibrancy and depth, making them ideal for a wide range of cosmetic applications, from eyeshadows to lipsticks, and nail polishes.
In line with GEOTECH's commitment to safety and regulatory compliance, the Geopearl® C Crystal Super Deep pigments are formulated to meet stringent global cosmetic standards. They are non-toxic and resistant to water and solvents, ensuring that they can be used safely in various cosmetic formulations. Moreover, these pigments comply with regulations concerning the ban on microplastics, making them not only beautiful but also an environmentally responsible choice for cosmetic manufacturers.

Micaceous Iron Oxide (MIO) is a naturally occurring iron oxide used in protective coatings due to a lamellar/platy morphology that allows it to form a barrier towards the ingress of water.
Thermochromic pigments, such as Chromazone®, enable formulators to create products with dynamic and heat-sensitive, colour changes. These smart materials have found their way into various applications, from functional safety indicators to eye-catching promotional products. For example, reversible thermochromic pigments are used in novelty mugs that reveal hidden designs when filled with hot beverages, packaging that signals when food or drink is at the optimal temperature for consumption, security labels for brand protection and anti-counterfeiting, and temperature-sensitive warning indicators on surfaces or medical devices.
