3. Increased Adhesion HPMC contributes to better adhesion of the putty to the substrate. The polymer creates a molecular bond that holds the putty securely to the surface, reducing the likelihood of peeling or cracking as the putty dries. This property is crucial for ensuring the longevity and durability of the putty application.

Overall, the price of hydroxyethyl cellulose is influenced by a complex interplay of factors, including market demand, production costs, and quality. While these factors can cause the price of HEC to fluctuate, it remains a popular choice for a wide range of applications due to its unique properties and versatility. As demand for HEC continues to grow, suppliers will need to carefully balance these factors to ensure a steady supply of high-quality HEC at a competitive price.

The cosmetic industry has also embraced HPMC for its thickening and film-forming abilities. It is commonly found in lotions, creams, shampoos, and other personal care products, contributing to a pleasant texture and increased stability. HPMC is non-irritating and suitable for sensitive skin, making it an ideal ingredient in a variety of formulations. Its capacity to enhance moisture retention ensures that cosmetic products not only apply smoothly but also provide lasting hydration benefits.

In consideration of the proposed revision of the limit for propylene chlorohydrins, the Committee took into account the extensive available toxicological database, most notably studies conducted by the United States National Toxicology Program. These data, together with the Committee’s previous estimate of dietary intake of HPMC, indicated that levels of propylene chlorohydrins up to 1 mg/kg in HPMC were not of toxicological concern.
