The biological activity, biocompatibility, and corrosion resistance of implants depend primarily on titanium dioxide (TiO2) film on biomedical titanium alloy (Ti6Al4V). This research is aimed at getting an ideal temperature range for forming a dense titanium dioxide (TiO2) film during titanium alloy cutting. This article is based on Gibbs free energy, entropy changes, and oxygen partial pressure equations to perform thermodynamic calculations on the oxidation reaction of titanium alloys, studies the oxidation reaction history of titanium alloys, and analyzes the formation conditions of titanium dioxide. The heat oxidation experiment was carried out. The chemical composition was analyzed with an energy dispersive spectrometer (EDS). The results revealed that titanium dioxide (TiO2) is the main reaction product on the surface below 900°C. Excellent porous oxidation films can be obtained between 670°C and 750°C, which is helpful to improve the bioactivity and osseointegration of implants.

  • In the paint and coatings sector, HEC is used as a thickener and stabilizer. It ensures a smooth, consistent finish and prevents settling or sagging during application. It also provides excellent film formation and improves the resistance to water and weathering.
  • Hydroxypropyl Methyl Cellulose (HPMC) is a versatile and widely used chemical compound in various industries. Its HS code, which stands for Harmonized System Code, is a standardized system for classifying goods for international trade purposes. The HS code for HPMC is 3912, which falls under the category of Macromolecular substances obtained by reactions other than polymerisation.
  • In the world of topical formulations, HPMC serves as an exceptional thickener and stabilizerhpmc formulation. Its non-ionic nature allows it to be compatible with a broad range of active ingredients, making it suitable for a variety of creams, lotions, and gels. The viscous solution formed by HPMC ensures that the active ingredients are evenly distributed and remain stable throughout the product's shelf life.
  • In the pharmaceutical sector, HPMC is classified as an excipient, meaning it is used as a non-active ingredient in medications. It is commonly found in tablet coatings, acting as a film former providing a protective layer around the pill. Additionally, it is used in capsule production due to its ability to form gels, facilitating the controlled release of active ingredients in the digestive system.
  • The selection of the right bonding agent is a critical decision in construction. Factors such as the type of masonry, environmental conditions, and expected load-bearing capacity must all be taken into consideration. Incorrect choice or application can lead to weak bonds, increased porosity, and ultimately, reduced lifespan of the structure.

  • In the pharmaceutical industry, hydroxypropyl methylcellulose is used as an excipient in various drug formulations. It is often added to tablets, capsules, and ointments to improve drug release, solubility, and bioavailability. Hydroxypropyl methylcellulose also acts as a suspending agent, emulsifier, and as a thickening agent in liquid dosage forms such as syrups and suspensions. Its inert nature and biocompatibility make it an ideal choice for pharmaceutical applications.

  • HPMC was first discovered in 1891, but it wasn't until 1951 that the pharmaceutical industry started using HPMC in its products. It was recognized as a safe drug delivery system when it was used with other drugs that were poorly absorbed or eliminated from the body. In 1967, HPMC was approved by the FDA for use in over-the-counter medicines such as cough syrups and throat sprays, as well as topical creams and gels for the treatment of minor burns and skin conditions such as eczema or psoriasis. In today's world, many consumers are using natural remedies on their skin or seeking alternative treatments for chronic diseases such as diabetes, heart disease, and high blood pressure.
