Carbomer Ultrez 20 represents the pinnacle of modern copolymer technology in rheological design. Chemically described as a cross-linked polyacrylic acid copolymer containing a hydrophobic comonomer (specifically an alkyl acrylate chain, C10-30), this polymer transitions from an unneutralized, tightly coiled configuration to a highly hydrated, spatial network upon neutralization.
Traditional carbomers demand prolonged wetting and hydration protocols to prevent the formation of "fish-eyes" (undissolved gel particles wrapped in a hydrated outer membrane). Ultrez 20 addresses this fundamental industry bottleneck through a proprietary surface-modification process that enables self-wetting. In aqueous systems, it disperses within minutes without the high-shear agitation that often introduces air bubbles and compromises gel clarity.

Navigating supply chain volatility while upgrading cosmetic formulation performance requires a dual focus on chemical stability and reliable volume output.
Global procurement teams struggle with quality consistency, volatile lead times, and trace solvent contamination. We address this with localized hubs, rigorous feedstock verification, and a continuous polymerization setup that outputs batch-to-batch consistency with guaranteed low residual monomer profiles.
From suspension of heavy exfoliants in body washes to stabilizers in high-oil-load O/W skin creams, Ultrez 20 offers polymeric emulsification capabilities that lower surfactant demand, leading to milder skincare end-products with elegant sensory profiles.
Under strict green-chemistry initiatives, traditional benzene polymerization is obsolete. Our ODM/OEM manufacturing utilizes environmentally conscious cosolvent mixtures, conforming directly with European REACH and California Proposition 65 requirements.
Founded in 2013 and headquartered in the prestigious high-tech zone of Xi'an, Xi'an Aoge Biotech Co., Ltd., along with its subsidiaries Xi'an Imaherb Biotech Co., Ltd. and Xi'an Nahanutri Biotech Co., Ltd., has established itself as a leading force in the cosmetics raw materials industry.
Our expansive cooperative factory, spanning 1,000 mu (approximately 165 acres), is equipped with state-of-the-art extraction technology. This advanced infrastructure allows us to manufacture a wide array of premium cosmetic raw materials. Our product line includes natural plant extracts specifically designed for organic cosmetics, as well as synthetic ingredients for high-end skincare formulations. These raw materials serve as the foundation for a multitude of skincare, haircare, and makeup products, ensuring superior quality and efficacy throughout the entire production process.

We are phasing out standard polymerization solvents in favor of a specialized ethyl acetate and cyclohexane co-solvent loop. This ensures that the resultant Ultrez 20 meets the most rigorous regulatory limits for volatile organic impurities without sacrificing the polymer's peak viscosity characteristics.
R&D is currently testing bio-sourced acrylic acid precursors derived from fermented biomass. Our goal is to offer a hybrid bio-synthetic Ultrez 20 variant by 2026, delivering identical performance profiles with a reduced carbon footprint.
By pairing synthetic cross-linked acrylates with refined biopolymers (like sclerotium gum, xanthan gum, and plant-derived oligosaccharides), we are designing pre-blended systems that yield outstanding sensory profiles, immediate wetting capability, and naturality indices exceeding 75%.
Our in-house lab uses advanced instruments like UPLC, HPLC, GC-MS, ICP-MS for quality control, ensuring raw materials meet strict international standards.
We pour relentless efforts into research and development, constantly exploring novel raw materials and advanced manufacturing techniques to stay ahead in the dynamic cosmetics industry.
Rigorous quality control is embedded in every step of our production process, from raw material sourcing to final product delivery, guaranteeing that each item adheres to the most stringent international standards.
Meanwhile, we actively embrace sustainable practices, striving to minimize our environmental footprint through eco-friendly production methods and responsible sourcing.
This unwavering dedication enables us not only to consistently offer products of unparalleled excellence but also to contribute to the long-term, healthy development of the entire cosmetics industry.
As a global exporter, we supply comprehensive compliance portfolios for all target jurisdictions. We facilitate direct clearance under regional frameworks with full documentation support.
Our quality assurance department enforces strict compliance policies across all raw material manufacturing lines. We employ advanced chromatography and mass spectrometry systems to verify molecular parameters.
Our analytical protocols include testing for trace contaminants, unreacted monomers, and residual solvent limits. By checking raw materials under varying temperature cycles, we ensure that exported products resist degradation and maintain consistent properties during ocean freight and long-term storage.
UPLC & HPLC Analytics: Verifies the composition purity and stability indexes of organic raw materials.
GC-MS Trace Analysis: Confirms the absence of benzene and monitors residual volatile organic compounds (VOCs).
ICP-MS Analysis: Detects heavy metals (Pb, As, Hg, Cd) down to parts-per-billion (ppb) levels.
Key considerations for developers and sourcing managers integrating Ultrez 20 and related raw materials into cosmetic lines.
