Pharmaceutical Grade Sodium Carboxymethyl Cellulose CMC Quality Standards

Pharmaceutical - Grade Sodium Carboxymethyl Cellulose (CMC) is a commonly used excipient in the pharmaceutical field. Its Quality Standard is critical to the safety and efficacy of the drug. First, the appearance properties must be white to slightly yellow powder or particles, without visible impurities, uniform texture, this is the basic visual judgment standard, which is related to the intuitive quality of the product. Second, the degree of substitution is extremely important. The degree of substitution refers to the degree of substitution of hydroxyl groups in cellulose glucose units by carboxymethyl groups. The degree of substitution of pharmaceutical-grade CMC often needs to reach 0.6 - 0.95. The appropriate degree of substitution can affect the solubility, viscosity and stability of CMC. If the substitution is too low, the solubility of CMC in water is not good, and it cannot effectively exert its functions such as thickening and dispersing; if the substitution is too high, its stability may decrease. Third, viscosity is also a key indicator. According to different medicinal needs, the viscosity range varies greatly, and is generally measured in milliPa · s (mPa · s). For example, when used in oral preparations, low viscosity is often required to ensure the taste and fluidity of the preparation; when used in external preparations, such as ointments and gels, high viscosity may be required to maintain the stability of the formulation. Fourth, in terms of purity, the impurity content should be strictly controlled. Excessive impurities such as sodium chloride may affect the osmotic pressure of the drug, which in turn affects the absorption and distribution of the drug; heavy metals and microbial limits must also meet strict standards to prevent the introduction of harmful substances and endanger the health of patients. Fifth, the pH range usually needs to be maintained at 6.0-8.5. An appropriate pH value helps to ensure the stability of CMC in different drug systems and avoid abnormal pH value affecting drug activity or causing adverse reactions.

Pharmaceutical Grade Sodium Carboxymethyl Cellulose CMC During Storage and Transportation

Pharmaceutical grade sodium carboxymethyl cellulose (CMC) requires many matters to be paid attention to during storage and transportation. Its nature prefers dryness, and if placed in a humid place, it is very easy to absorb moisture.

Therefore, when storing, it must be selected in a dry, ventilated and humidity-controlled place. The relative humidity should be controlled within a specific range, generally speaking, no more than 60%. Temperature is also crucial. Excessive temperature may cause it to degrade, and too low temperature may affect its solubility and performance. Usually the suitable storage temperature is between 5 ° C and 35 ° C. Do not expose the drug to extreme high or low temperature environments. When transporting, the packaging must be intact. Due to its delicate texture, if the packaging is damaged, it is easy to cause powder leakage during handling, which not only wastes materials, but also pollutes the surrounding environment. And in the transportation vehicle, it should also be kept dry and at a suitable temperature to avoid rain and sun exposure. In addition, pharmaceutical-grade CMC is a pharmaceutical excipient, which is related to drug safety. The place of storage and transportation must not be stored and transported with toxic, harmful, and odorous substances to prevent cross-contamination. The transportation process should also be as smooth as possible to avoid violent vibration and collision, which will cause damage to the packaging or change the quality.
