Carbopol 340 comes in different types that are primarily classified based on their viscosity, acrylate content, pH sensitivity, and application. The following are the common types of Carbopol. Business owners must understand this compound's diverse needs to supply the right one.
Carbopol Ultrez 10
This Carbopol type has high purity and is ideal for formulating high-viscosity gels. It features lower ionic content than previous Carbopol types, allowing better formulation stability in products containing electrolytes. Carbopol Ultrez 10 is ideal for cosmetic and personal care gel formulations, specifically hair and skin gels.
Carbopol 980
Carbopol 980 is a highly cross-linked acrylic polymer grade typically used in formulations requiring gel with low shear. It has superior clarity, making it suitable for cosmetic products where transparency is essential. This compound swells readily in water and works well in neutralized formulations.
Carbopol 940
One of the most common types of Carbopol is Carbopol 940. It has excellent thickening properties and is used in a wide range of cosmetic and pharmaceutical formulations. The polymer swells when dispersed in water and produces a gel with high viscosity. It is neutralized with triethanolamine (TEA) for optimal results.
Carbopol 934
Carbopol 934 is similar to Carbopol 940, but this type is often used in lower viscosity formulations. It is ideal for liquids like lotions and creams as it produces moderate thickening without excessive gel formation. It typicaly works in formulations requiring less viscosity, where thinner consistency is needed.
Carbopol ETD 2020
Carbopol ETD 2020 is designed for easy hydration and dispersion. Compared to other types, it has faster gel formation, making it suitable for formulations where quick preparation is desired. This carbomer is often used in hair styling gels and other personal care products.
Carbopol 340 is a versatile substance with a wide range of uses across various industries. Understanding how it is used helps wholesalers stock it for different applications.
Cosmetics and Personal Care Products
Carbopol 340 is mainly used as a thickening and suspending agent in cosmetic and personal care products. It gives creams, lotions, and gels smooth and appealing texture. It is commonly found in moisturizers, acne treatment gels, and hair styling products like gels and mousses. Cosmetic manufacturers use Carbopol 340 to improve product stability and prevent the separation of ingredients, ensuring a consistent and attractive formulation.
Pharmaceuticals
In the pharmaceutical industry, Carbopol 340 is commonly used in preparing topical formulations such as gels, creams, and ointments. It acts as a thickening agent, giving the right consistency for easy application on the skin. This Carbopol grade is used in extended-release drug formulations as a binder. When neutralized, it forms a gel that can help control the rate of drug release over time.
Industrial Applications
Carbopol 340 is used in the coating industry to formulate paints and coatings. The polymer helps improve the paint's viscosity, making it easier to apply while preventing pigment settling. Coatings formulated with Carbopol 340 have better shear thinning properties. They provide the right consistency for application and reformulate thicker upon application for better coverage.
Agricultural Products
Carbopol 340 serves as a thickening and suspending agent in agricultural formulations, such as pesticides and herbicides. It helps evenly suspend active ingredients in liquids, ensuring proper dosage and application. Carbopol's ability to reformulate helps these agricultural products stay mixed and effective over longer periods before settling.
Printing Inks
Carbopol 340 is commonly used in the ink manufacturing industry. It helps improve the viscosity and flow characteristics of printing inks. Inks formulated with Carbopol 340 have better stability and smoother application. This leads to higher quality prints with improved colors and consistency on different surfaces. For this reason, many industries prefer inks printed with this polymer to its stable and vibrant prints.
Although many things determine the buyers' success when purchasing Carbopol 940, the essential ones are robustness and quality. Here are the key ones:
Quality and Purity
Ensure the Carbopol 340 is manufactured with high-quality materials, especially if intended for cosmetics, pharmaceuticals, or food industries. It should be free of contaminants and have a consistent molecular weight and grade. Check if the supplier provides certificates of analysis (COA) to confirm purity and quality standards. The COA usually contains important information like the date manufactured, batch number, and specifications.
Reputation
Before placing an order, do some research on the online market's reputation and customer reviews. Pay attention to their customer service and responsiveness to quality complaints or issues. While at it, check their certifications. Ensure they comply with industry standards and regulations for producing chemicals like Carbopol 340. ISO or GMP certifications can indicate a commitment to quality and manufacturing consistency.
Source in Bulk
It is important to find a reliable supplier who can deliver Carbopol 340 in bulk consistently. For buyers sourcing it for resale, inconsistent supplies can damage their business. Large orders can sometimes lead to negotiation of better pricing and terms. Once settled, use the bulk purchase to build stock for steady supply to customers. This also saves on reiterative costs.
Storage and Shelf Life
When buying in bulk, consider the storage conditions for Carbopol 340 to ensure its integrity is not affected. Since it is a synthetic polymer, make sure it is stored in a cool, dry place, away from direct sunlight. Make sure to check the shelf life and bulk purchases are typically rotated to use older stock first.
Samples
If unsure about a particular supplier's grade of Carbopol 340, ask for samples before placing a large order. This is particularly beneficial for companies developing new products or formulations. Testing samples internally helps determine if the polymer meets required viscosity, stability, and compatibility for intended uses.
Although mainly used in cosmetics and pharmaceuticals, Carbopol 340 can also be used in the food industry. Buyers purchasing it for this purpose should ensure the polymer meets food grade standards. More importantly, they should look for carbomers specifically designed for food applications. They have high purity levels and are safe for human consumption. They should also consider the intended use in food products. Carbopol 340 works better as a thickening or stabilizing agent in certain food preparations, such as sauces, gels, and emulsions. Considering storage conditions will help maintain its integrity in the food environment.
The secret to getting consistent products with every batch of purchased Carbopol 340 is to buy the same grade from the same supplier. This consistency is important, especially for manufacturers who use it to produce products with specific viscosity and stability. Notice that suppliers will usually have a lot number on every batch. This number helps trace the manufacturing process and raw materials used.
To take things further, buyers can establish a quality control process. This process involves inspecting every batch upon receipt and testing samples in formulations when necessary. It is also a good idea to work closely with the supplier to ensure they meet required specifications consistently.
Carbopol 340 is safe for sensitive skin, as manufacturers usually use it in skincare and pharmaceutical products. It is important to note that people's skin sensitivity differs. That is why it is always advisable to do a patch test before using products containing Carbopol 340.
At this stage, it is also worth noting that safety and skin compatibility largely depend on the product's overall formulation. If unsure about the safety of Carbopol 340, users can consult their dermatologists for professional advice. They will consider the user's specific needs and sensitive concerns.
Carbopol 340 has been specially formulated for high performance. Compared to other carbopol types like 940 and 934, it has higher viscosity, offering better stability to formulations. Its superior flow properties set it apart from Carbopol 941, which cannot be neutralized easily and needs less shear to disperse. What is more, manufacturers have added Electrolye to make it compatible with other formulation ingredients.
Carbopol 340 has also been designed for high clarity. It does not only improve the product's aesthetic appeal but also its effectiveness. Lastly, compared to others, Carbopol 340 forms a gel with excellent stability when neutralized with triethanolamine.
