2. Pharmaceuticals HEC is extensively used in pharmaceutical formulations as a suspending agent, especially in liquid medications. It helps to maintain the uniform distribution of active ingredients, ensuring consistent dosages. Additionally, HEC is employed in gel formulations, providing viscosity and stability, which are crucial for both topical and oral medications.

3. Cosmetics HPMC is widely used in cosmetic formulations for its thickening and film-forming properties. It enhances the texture of creams, lotions, and gels, providing a pleasant application experience while also contributing to the product's stability.

Applications of HPMC

Chemical Structure and Properties

1. Improved Workability One of the most significant advantages of adding HPMC to gypsum plaster is enhanced workability. The polymer increases the viscosity of the plaster mix, leading to better consistency and smoother application. This allows contractors to achieve more uniform surfaces with fewer finishing issues, reducing labor time and improving overall project efficiency.

Cellulose itself is a linear polysaccharide composed of repeating units of glucose. The structure of cellulose is characterized by extensive hydrogen bonding between chains, which leads to its high tensile strength and insolubility in water. By chemically modifying cellulose, HEC is produced, altering its hydrophilicity due to the hydroxyethyl groups that disrupt the hydrogen-bonding network. The degree of substitution, or the number of hydroxyethyl groups introduced per glucose unit, can influence the properties of HEC, including its solubility, viscosity, and thickening capacity.

In personal care products, HPMC is frequently found in lotions, creams, and gels. Its thickening and emulsifying properties enhance the viscosity and stability of formulations, leading to improved product performance and sensory attributes. HPMC is also used in hair care products, where it can provide a conditioning effect, contributing to easier combing and styling. Additionally, its film-forming ability allows for the creation of transfer-resistant make-up formulations, which adhere better to the skin and last longer throughout the day.

5. Incorporation of Additives If your formulation requires the inclusion of preservatives or APIs, this should be done after the gel has cooled to avoid thermal degradation of sensitive components. Ensure to mix thoroughly for uniform distribution.
