ในอุตสาหกรรมยา เอธิลเซลลูโลสถูกใช้เป็นสารที่ช่วยในกระบวนการเคลือบยา ทำให้สามารถควบคุมการปล่อยยาออกสู่ร่างกายได้อย่างมีประสิทธิภาพ ซึ่งช่วยเพิ่มการดูดซึมของยาในร่างกาย นอกจากนี้ ยังช่วยป้องกันการเสื่อมสภาพของยาเมื่อสัมผัสกับอากาศหรือน้ำ

Carboxymethyl cellulose is produced by the chemical modification of cellulose through a process known as etherification. In this process, hydroxyl groups in the cellulose structure are replaced with carboxymethyl groups, thus enhancing water solubility and making it applicable in various aqueous systems. The degree of substitution—the average number of hydroxyl groups in cellulose replaced by carboxymethyl groups—affects the properties of CMC, including its viscosity and solubility.

In cosmetic formulations, HPMC E5 is employed for its thickening properties, allowing for the creation of stable emulsions and gels. The viscosity of HPMC E5 contributes to the sensory attributes of personal care products, influencing how a product feels upon application. Its ability to form a smooth, uniform texture can enhance user experience, making it a popular choice in lotions, creams, and other topical applications.

One of the primary benefits of HPMC capsules is their enhanced stability. Unlike gelatin, which can be sensitive to humidity and temperature fluctuations, HPMC capsules maintain their integrity, ensuring that the active ingredients remain protected. This stability is particularly crucial for moisture-sensitive formulations, as it reduces the risk of degradation over time.
