Carbomer 940 Powder

Carbomer 940 Powder – Professional Thickening Agent for Cosmetic & Personal Care Applications

Xi'an Le-Nutra Ingredients Inc. supplies industrial-grade Carbomer 940 Powder (CAS 9003-01-4), a polyacrylic acid-based rheology modifier widely recognized for its exceptional thickening and stabilizing properties in cosmetic formulations. With over 14 years of manufacturing expertise, our facility operates 6 advanced production lines across a 60,000㎡ GMP-certified base, delivering 3,000 tons annually with ≥98% purity verified by HPLC analysis. Our product achieves optimal viscosity at 0.5-2% dosage, reduces formulation costs by 30-40% compared to alternative thickeners, and maintains stable pH performance between 6.0-11.0, making it the preferred choice for global cosmetic manufacturers seeking reliable, cost-effective thickening solutions.

Technical Specifications

Formulation Advantages for Industrial Applications

This carbopol 940 substance provides solutions to three manufacturing difficulties in cosmetic production. Firstly, it has very high effectiveness at very low dose of around 0.5-2% concentration to make stable gel structures, thereby greatly decreasing raw material costs. Second, it standardises the molecular weight distribution and viscosity properties to ensure batch-to-batch consistency.

The polymer structure offers high electrolyte tolerance and pH stability. Your compositions are homogenous even with active constituents bearing different charges. The compatibility prolongs the shelf life and lowers the rates of formulation failure in QC testing.

Third, the Carbomer 940 Powder form has no liquid handling issues. You eliminate the corrosive nature and shipping weight penalty of pre-neutralized liquid polymers. The free-flowing powder fits well with automated dispensing systems, enhancing efficiency on the production line.

Multi-Industry Application Scope

Transparent Gel Systems

Optical clarity and the right viscosity are required for clear hand sanitisers, disinfection gels and alcohol-based antiseptic solutions. This thickener forms crystal clear matrices without cloudiness even at high alcohol concentrations.

​​​​​​​Advanced Skin Care Formulations

Moisture-retention features they will love: serums, essences and moisturising creams. The polymer network is cross-linked to form a permeable layer on the skin surfaces, which locks in hydration while facilitating transdermal transport of active chemicals. Your products give consumers that coveted silky feel of luxury skin care.

Hair Care Products Development

Styling gels and leave-in conditioners and hair treatments add hold and definition. The polymer creates pliable films that fight humidity-induced frizz without flaking or rigidity.

Stability of Emulsions

Lotions and creams remain stable in phase during shelf life. This thickening mechanism minimises the separation of oil and water in O/W emulsions and hence reduces customer complaints of product separation.

Quality Assurance and Compliance Framework

Our quality management system is based on internationally accepted standards of manufacture of cosmetics. Each batch made is tested for viscosity with the Brookfield method, tested for pH and fully screened for safety in terms of heavy metals and microbiological contamination.

All shipments are sent with the full documentation: Certificate of Analysis (COA), Technical Data Sheet (TDS), allergy declarations and Non-GMO certifications. Our facility is ISO and GMP certified and is verified by third-party audits. Halal and Kosher certificates are available on request for certain market needs.

We can follow the entire process from the production of the raw polymer to the final packaging. Our R&D laboratory can offer method development support adapted to your regulatory jurisdiction if your quality team requires further testing protocols or bespoke specifications.

Professional OEM/ODM Customization Services

Your brand might need special formulation parameters that are not covered by specs. We provide a range of fully customisable options in several dimensions: grades of purity from 95% to 99%, particle size distribution tailored to specific dispersion equipment, and pH-adjusted versions for certain applications.

Our technical staff collaborates on private label development including unique package configurations from 1kg laboratory samples to bulk 1000kg supersacks. Formula development services also include the production of entire completed product prototypes that meet your target viscosity, texture and sensory profiles.

If you are entering a market for the very first time, we can help you prepare the regulatory dossier and give you stability testing results to back up your product registration needs in several countries.

FAQ

Q: What is the optimal neutralization procedure for achieving maximum viscosity?

A: Add 1-1.5% powder gradually to water with moderate agitation. Add neutralisers such as triethanolamine or sodium hydroxide gently to a pH of 6.5-7.5 after full hydration (about 2-4 hours). • Avoid quick pH adjustment as this causes air entrapment and loss of clarity.

Q: How does this compare with other carbomer grades such as 934 or 980?

A: The product gives the clearest gels with the maximum viscosity efficiency, excellent for transparent applications. Grade 934 gives improved electrolyte tolerance for high salt formulations and Grade 980 has shorter flow properties for thick creams.

Q: What causes viscosity loss during storage?

A: Exposure to humidity of more than 60% RH results in premature hydration and cross-linking. Store in sealed, moisture proof containers with desiccant packs. After opening, use within 6 months under dry storage conditions.

Q: Is it approved for use in certified organic cosmetics?

A: The polymer itself is synthetic, and is not often acknowledged with strict organic requirements. But it may be allowed under natural cosmetic certifications, depending on the tolerance of your certifying body for processing aids and rheology modifiers.

Q: What is your technical support policy throughout formulation development?

A: We offer free technical assistance, including recommended usage rates, compatibility testing data and troubleshooting guidance. More sophisticated applications needing considerable R&D resources can have custom formulation development on a fee basis.
