Benecel K4M Hydroxypropyl Methylcellulose (HPMC) | 18 kg Box
Benecel K4M Hydroxypropyl Methylcellulose is an Ashland-produced cellulose derivative used in food, nutraceutical, and pharmaceutical formulations. Also commonly referred to as HPMC or hydroxypropylmethylcellulose, Benecel K4M is supplied as an off-white, odorless powder or granular material.
In food formulations, Benecel K4M can provide functional properties including aeration and emulsification. These characteristics make it useful in applications such as frozen desserts, ice cream, frozen novelties, and sherbets. HPMC can also be incorporated into gluten-free bakery formulations where its functional properties are appropriate for the finished product.
Benecel K4M may also be used as an excipient in nutraceutical and pharmaceutical formulations. Ashland identifies pharmaceutical use as a recommended application for this grade.
Benecel K4M meets Ashland's defined specifications for viscosity, pH, substitution levels, loss on drying, and sulphate ash. Its specified viscosity is 2,700 to 5,040 mPa·s in a 2% solution on a dry basis, providing formulators with a defined K4M viscosity range for product development and manufacturing.
