Titanium dioxide (E171) is a common food additive used for its whitening and opacity properties in various products, including candies. It helps achieve a bright, consistent color and prevents ingredients from separating. Some candies that contain titanium dioxide include popular brands like Starburst, Skittles, and certain varieties of M&M's, particularly those with white candy shells. However, its usage varies by region and specific product formulations, so always check the ingredient list. While generally recognized as safe by regulatory agencies, concerns have been raised about potential health impacts from long-term exposure or inhalation of very fine particles. As a result, some manufacturers have started reducing or eliminating its use.
Propylene glycol (PG) and polypropylene glycol (PPG) are both derived from propylene oxide. The key difference is in their molecular structure. Propylene glycol is a small molecule, essentially a diol with two alcohol groups, used in food, pharmaceutical, and cosmetic industries due to its ability to absorb water and its non-toxic nature. On the other hand, polypropylene glycol is a polymer, formed by linking multiple propylene glycol molecules together. This results in a substance with a higher molecular weight and viscosity, making PPG suitable for industrial applications, such as in polyurethane foams, lubricants, and certain pharmaceutical formulations. The choice between PG and PPG depends on the specific properties needed for the application, such as solubility, hygroscopicity, and lubrication.
Tencel yarn is a sustainable fiber made from wood cellulose, primarily eucalyptus trees. Developed by Lenzing AG, Tencel, also known as Lyocell, is produced through an environmentally responsible process that recycles water and reuses the solvent at a recovery rate of more than 99%. Tencel yarn is known for its durability, moisture-wicking properties, and softness, making it a popular choice for clothing, bedding, and textiles that require a smooth, gentle touch on the skin. Its breathability and moisture management make it particularly suitable for sensitive skin. The production process is eco-friendly, contributing to its popularity among those seeking sustainable textile options. Tencel yarn blends well with other fibers, enhancing strength, comfort, and versatility in fabric design.
