Overview
Maltodextrin Titanium Dioxide is a composite material that combines maltodextrin, a polysaccharide derived from starch, with titanium dioxide, a widely used white pigment. This combination leverages the solubility and binding properties of maltodextrin with the opacity and brightness of titanium dioxide. The material is commonly used in industries where whiteness and stability are critical, such as food, pharmaceuticals, and cosmetics. The composite is particularly valued for its ability to enhance product appearance without compromising safety or functionality. Maltodextrin serves as a carrier, improving the dispersibility of titanium dioxide in aqueous solutions, which is essential for uniform application in various formulations.
Physical and Chemical Properties
Maltodextrin Titanium Dioxide typically appears as a fine white powder with a density ranging from 1.5 to 1.7 g/cm³. It is highly soluble in water, making it suitable for liquid formulations. The material exhibits excellent stability under normal processing conditions, including moderate heat and pH variations. One of the key properties of this composite is its opacity, which is derived from titanium dioxide. This makes it ideal for applications requiring high whiteness or coverage. Additionally, the maltodextrin component ensures that the titanium dioxide particles remain evenly dispersed, preventing clumping and ensuring consistent performance in end products.
Main Applications
Maltodextrin Titanium Dioxide is widely used in the food industry as a whitening agent and opacifier. It is commonly found in products like confectionery, dairy alternatives, and baked goods, where it enhances visual appeal. In the pharmaceutical sector, it is used in tablet coatings to improve appearance and protect active ingredients. The material also finds applications in cosmetics, such as in foundations and sunscreens, where it provides opacity and UV protection. Industrial uses include coatings and paints, where it contributes to brightness and durability. The versatility of this composite makes it a valuable additive across multiple industries.
Safety and Storage
Maltodextrin Titanium Dioxide is generally recognized as safe (GRAS) for food use, provided it meets regulatory standards. However, inhalation of the powder should be avoided, as it may cause respiratory irritation. Proper handling, including the use of personal protective equipment (PPE) like masks and gloves, is recommended. Storage conditions are critical to maintaining the material's quality. It should be kept in a cool, dry place away from direct sunlight and moisture. Properly sealed containers are essential to prevent contamination and degradation. Suppliers should provide safety data sheets (SDS) to ensure compliance with local regulations.
B2B Procurement Guide
When procuring Maltodextrin Titanium Dioxide, B2B buyers should prioritize suppliers who provide certificates of analysis (COA) to verify purity and compliance with industry standards. Food-grade applications require additional documentation, such as FDA or EU approval, depending on the region. Price negotiations should consider factors like order volume, packaging, and delivery terms. Bulk purchases often attract discounts, but buyers should ensure that storage facilities can handle large quantities without compromising product quality. Establishing long-term relationships with reliable suppliers can lead to better pricing and consistent quality.
