General Description
Sodium Carboxymethyl Cellulose (CMC) is a water-soluble cellulose derivative widely used as a thickener, stabilizer, and film-forming agent in various industries, including cosmetics, pharmaceuticals, and food. As a plant-based polymer, it enhances the texture and performance of formulations. Manufacturers produce CMC in different grades to suit industrial applications, making it a highly sought-after ingredient for bulk and wholesale sales.
Uses in the Cosmetics Industry
CMC is a multifunctional ingredient in skincare, haircare, and personal care products, providing the following benefits:
- Thickening Agent: Enhances viscosity and texture in creams, lotions, and serums.
- Stabilizer: Prevents ingredient separation, ensuring long-lasting product stability.
- Moisture Retention: Helps maintain hydration in skincare and haircare formulations.
- Film-Forming Properties: Creates a protective layer on the skin and hair, improving smoothness and softness.
Due to its excellent safety profile, CMC is widely used in facial cleansers, shampoos, conditioners, sunscreens, and even decorative cosmetics like foundation and mascara. If you are looking to buy Sodium Carboxymethyl Cellulose (CMC) in bulk or wholesale, choosing high-purity cosmetic-grade CMC ensures optimal product performance.
Side Effects & Hazards
CMC is generally considered safe for cosmetic use, but some precautions should be taken:
- Mild Skin Irritation: Rarely, some individuals may experience slight redness or sensitivity.
- Eye Irritation: Direct contact with CMC powder or high concentrations in formulations can cause irritation.
- Inhalation Risk: Fine CMC powders may cause respiratory discomfort if inhaled during manufacturing.
Proper handling, storage, and formulation techniques help prevent unwanted side effects. Cosmetic manufacturers should use high-quality CMC from reputable wholesale suppliers to ensure safety and performance.
CAS NO. :- 9004-32-4
INCI:- Sodium Carboxymethyl Cellulose
COMPOSITION:-CMC Sodium is a cellulose derivative obtained by chemically modifying natural cellulose with chloroacetic acid and sodium hydroxide.
The resulting product contains sodium carboxymethyl groups (-CH2-COONa) attached to the cellulose backbone.
PURITY GRADE:-Available in various grades, including:
Pharmaceutical grade: High purity, suitable for sensitive applications.
Cosmetic grade: 99% or higher, suitable for personal care formulations.
APPEARANCE:-White to off-white powder or granular form.
Odorless or with a slight characteristic odor.
SOLUBILITY:-Soluble in cold and hot water, forming clear or slightly hazy, viscous solutions.
Insoluble in organic solvents like ethanol or acetone.
PRESEVATION:-CMC Sodium does not require additional preservatives in its dry form.
Formulations using CMC may require preservatives to prevent microbial growth.
STORAGE:-Store in a cool, dry place, protected from moisture and direct sunlight.
Recommended storage temperature: 15–25°C (59–77°F).
Keep in sealed containers to prevent moisture absorption.
RAW MATERIAL SOURCE:-Derived from natural cellulose, typically extracted from wood pulp or cotton.
Processed using synthetic chemicals to produce carboxymethyl cellulose
MANUFACTURE:- Produced by treating cellulose with alkali (sodium hydroxide) and reacting it with chloroacetic acid to form the sodium carboxymethyl derivative.
Purified and dried to achieve desired grades.
ANIMAL TESTING:-Typically produced by manufacturers adhering to cruelty-free standards, though verification is advised for specific suppliers.
GMO:- Non-GMO, as it is derived from natural cellulose sources that are not genetically modified.
VEGAN:-Vegan-friendly, as it is derived from plant-based materials without involving animal-derived components.
WARNING: Skin and Eye Irritation: CMC Sodium is generally non-irritating, but highly concentrated solutions may cause slight irritation in sensitive individuals.
Dust Inhalation: Fine powder may cause respiratory irritation if inhaled during handling.
Quality Variability: Impurities or low-quality grades may affect performance in formulations
