  2. Hydroxypropyl cellulose - Wikipedia

    en.wikipedia.org/wiki/Hydroxypropyl_cellulose

    Hydroxypropyl cellulose (HPC) is a derivative of cellulose with both water solubility and organic solubility. It is used as an excipient , and topical ophthalmic protectant and lubricant. Chemistry

  3. Hypromellose - Wikipedia

    en.wikipedia.org/wiki/Hypromellose

    Hypromellose , short for hydroxypropyl methylcellulose (HPMC), is a semisynthetic, inert, viscoelastic polymer used in eye drops, as well as an excipient and controlled-delivery component in oral medicaments, found in a variety of commercial products.

  4. Methyl cellulose - Wikipedia

    en.wikipedia.org/wiki/Methyl_cellulose

    Derivatives of methyl cellulose which improve performance characteristics include hydroxypropyl methyl cellulose (HPMC) and hydroxyethyl methyl cellulose (HEMC). These derivatives typically improve the characteristics such as water retention, vertical surface slip resistance, open time, etc. [citation needed]

  5. Cellulose - Wikipedia

    en.wikipedia.org/wiki/Cellulose

    Cellulose is the most abundant organic polymer on Earth. [6] The cellulose content of cotton fibre is 90%, that of wood is 40–50%, and that of dried hemp is approximately 57%. [7] [8] [9] Cellulose is mainly used to produce paperboard and paper. Smaller quantities are converted into a wide variety of derivative products such as cellophane and ...

  6. Dissolving pulp - Wikipedia

    en.wikipedia.org/wiki/Dissolving_pulp

    As a raw material of cellulose derivatives, dissolving pulp is used in carboxymethyl cellulose (CMC), methyl cellulose (MC), hydroxypropyl cellulose (HPC), hydroxyethyl cellulose (HEC), etc. Since dissolving pulp is highly refined, it is a product of high whiteness with few impurities making it suitable in specialty paper-related products such ...

  7. Carboxymethyl cellulose - Wikipedia

    en.wikipedia.org/wiki/Carboxymethyl_cellulose

    Carboxymethyl cellulose (CMC) or cellulose gum [1] is a cellulose derivative with carboxymethyl groups (-CH 2-COOH) bound to some of the hydroxyl groups of the glucopyranose monomers that make up the cellulose backbone. It is often used in its sodium salt form, sodium carboxymethyl cellulose. It used to be marketed under the name Tylose, a ...

  8. Hydroxyethyl cellulose - Wikipedia

    en.wikipedia.org/wiki/Hydroxyethyl_cellulose

    Hydroxyethyl cellulose is a gelling and thickening agent derived from cellulose. It is widely used in cosmetics, cleaning solutions, and other household products. [ 1 ] Hydroxyethyl cellulose and methyl cellulose are frequently used with hydrophobic drugs in capsule formulations, to improve the drugs' dissolution in the gastrointestinal fluids.

  9. Artificial saliva - Wikipedia

    en.wikipedia.org/wiki/Artificial_saliva

    Cellulose derivatives are rheological modifiers, which are compounds responsible for the viscosity and texture of artificial saliva, enabling it to adhere to oral tissues and provide a protective and lubricating film. [9] The viscosity of cellulose derivatives is greater than that of natural human saliva. [10] Cellulose derivatives include:
