SUNROSE® is a product name for carboxymethyl cellulose (CMC) used by NIPPON PAPER CHEMICALS CO., LTD. CMC is an anionic, water-soluble polymer derived from cellulose that features unique properties of outstanding adherence, water absorption, and water retention. Moreover, because SUNROSE is naturally derived cellulose, it offers slow biodegradability and can also be incinerated after use, making it very environmentally friendly.

We have recently released two new product lines of SUNROSE, the MAC Series and F350HC-4. Ideal for ensuring paints and varnishes achieve a smoother and glossier finish, MAC Series' CMC-solution features undissolved gel-particles of smaller size, greatly reducing the incidence of streaking and pinholes. Additionally, even in anti salt solutions F350HC-4 offers outstanding viscosity characteristics; in fact, dissolving F350HC-4 in highly concentrated anti salt solution will increase its viscosity even more.

Grades and Properties of SUNROSE®

SUNROSE® is available in five grades as listed below, and for each grade there is a variety of products suited for various applications. Included are grades compatible with food additive standards, dietary additive standards, and pharmaceutical standards; cosmetic and pharmaceutical grades; and grades suited for industrial applications for use as thickeners, bonds and binders, as well as water absorbing/retention agents.

Grade	Purity (%)	Degree of etherification (DS)(mol/C6)	Viscosity (mPa/s 1%,25°C)	Applications
F	More than 99.0	0.55 - 1.0	7 - 15000	Food additive standards, pharmaceutical grade
A	More than 90	0.65 - 1.6	3 - 2000	Ultrahigh etherification, ultralow viscosity grade
P	80 - 90	0.55 - 0.65	7 - 1000	Printing and special papermaking grade
S	70 - 80	0.55 - 0.75	7 - 1000	Binder and civil engineering technical grade
B	More than 50	0.45 - 0.55	6 - 30	Detergent technical grade

Special-purpose products
Also available are granulated and finer-grained products such as the MAC Series and also the SLD Series of slightly carboxymethylated cellulose.
