Amid the booming development of the biomedical industry in the Yangtze River Delta, Neostar United (Changzhou) Industrial Co., Ltd. has rapidly emerged as a highly regarded comprehensive chemical products and services supplier, backed by profound industry expertise and a forward-looking global vision. As a high-tech enterprise integrating R&D, manufacturing, and sales, Neostar United is writing a remarkable chapter in the journey of Chinese biotechnology companies going global with its unique charm.

Company Profile: Solid Foundation, Steady Progress

Neostar United (Changzhou) Industrial Co., Ltd., a subsidiary of Neostar United Industrial Group, has been committed since its inception to providing high-quality products and professional solutions for the global pharmaceutical, agrochemical, flavor & fragrance, and functional chemicals sectors. Headquartered in Changzhou, Jiangsu Province, the company has strategically established multiple R&D and production bases across China, leveraging the comprehensive industrial chain support of the Yangtze River Delta. The company boasts a core R&D team led by overseas-returned PhDs and master's degree holders, demonstrating strong technological innovation and industrialization capabilities.

Adhering to the management philosophy of "High Quality, High Efficiency, High Reputation," the company has established a quality assurance system compliant with GMP standards, equipped with precision testing instruments such as Agilent HPLC, GC, and UV spectrophotometers, ensuring that every product withstands the most rigorous market scrutiny.

Flagship Products: Focus on High Value-Added Segments

Leveraging comprehensive chemical synthesis manufacturing capabilities and leading technologies including chiral synthesis and reduction reactions, Neostar United has built a highly competitive product portfolio in the pharmaceutical APIs and intermediates sector.

The company's core products focus on high-value-added APIs and advanced intermediates for oncology, antipsychotic, cardiovascular, and ophthalmic pharmaceuticals. In the oncology segment, for instance, the company's Anastrozole intermediates (such as Pentamethyl-1,3-diacetonitrilebenzene) achieve purity levels exceeding 98%. As key raw materials for breast cancer therapeutics, these products have earned broad customer trust due to their stable quality and excellent cost-performance ratio.

Furthermore, leveraging strong R&D capabilities and industrialization expertise, Neostar United has established a highly competitive product line in the personal care ingredients, sunscreen agents, and functional skincare actives sectors. The following five core products exemplify the company's technological strength and market insight:

1. Octocrylene–High-Efficiency Broad-Spectrum Sunscreen Agent

Octocrylene is an oil-soluble ultraviolet absorber, chemically known as 2-ethylhexyl 2-cyano-3,3-diphenylacrylate (CAS: 6197-30-4), appearing as a pale yellow viscous liquid. It effectively absorbs UVB and a portion of UVA radiation, offering high absorption efficiency, non-toxicity, and excellent photothermal stability. It is an FDA-approved Category I sunscreen agent and is widely used in the United States and Europe.

In sunscreen formulations, Octocrylene not only serves as an efficient UV absorber but also acts as an excellent solvent for solid chemical sunscreens. Additionally, it effectively stabilizes Avobenzone, enhancing the overall photoprotective efficacy and water resistance of the formulation. Neostar United's Octocrylene features high purity and stable quality, finding broad application in sunscreens, body care products, and fragrances. The maximum permitted usage level is 10% (compliant with major market regulations including EU, USA, CN, AUS, JP, and KR).

2. Piroctone Olamine–High-Efficiency Anti-Dandruff and Anti-Itch Agent

Piroctone Olamine is a high-efficiency, low-irritation broad-spectrum antifungal agent. It effectively inhibits the growth of dandruff-causing fungi such as Malassezia by blocking iron ion uptake. It is a star ingredient in anti-dandruff shampoos. Compared to conventional anti-dandruff agents (e.g., ZPT), Piroctone Olamine offers advantages including good water solubility, strong compatibility, and a mild, non-irritating profile for the scalp, making it widely used in premium hair care products. Neostar United supplies Piroctone Olamine with excellent purity, meeting the stringent quality standards of leading international personal care conglomerates.

3. 3-O-Ethyl-L-ascorbic Acid (Vitamin C Ethyl Ether)–Stable Whitening and Antioxidant Star

3-O-Ethyl-L-ascorbic acid (CAS: 86404-04-8) is an amphiphilic (hydrophilic and lipophilic) derivative of vitamin C, featuring an ethyl modification at the 3-position hydroxyl group. This modification significantly enhances stability under light and oxidative conditions, overcoming the industry challenges of easy discoloration and poor penetration associated with conventional vitamin C.

This product is a white to off-white powder with a purity of up to 99% or higher. It offers multiple benefits, including tyrosinase inhibition, melanogenesis suppression, potent antioxidant activity through free radical scavenging, and promotion of collagen synthesis. Owing to its amphiphilic nature, it readily penetrates the stratum corneum into the dermis, where it is enzymatically cleaved to release active vitamin C, achieving significantly superior bioavailability compared to ordinary vitamin C derivatives without yellowing the skin. The recommended dosage is 0.5%–2.0%, making it an ideal active ingredient for premium skincare products such as brightening serums and anti-aging creams.

4. Climbazole–Multifunctional Anti-Dandruff Hair Care Agent

Climbazole is a broad-spectrum antifungal agent with excellent inhibitory effects against Malassezia, the fungus responsible for dandruff. Complementing Piroctone Olamine through differentiated positioning, Climbazole holds a significant place in anti-dandruff shampoos, conditioners, and scalp care products. It features low irritation and high safety, effectively relieving scalp itchiness and improving the scalp's microecological balance. Neostar United produces Climbazole with consistent quality, having gained recognition and long-term procurement from numerous renowned domestic and international personal care companies.

5. UV Absorber UV-1084–Light Stabilization Expert for Plastics

UV-1084 is a high-efficiency light stabilizer that effectively absorbs ultraviolet radiation in the wavelength range of 270–330 nm. It provides both light stabilization and antioxidant functions. It is particularly suitable for polyolefin copolymers and other plastic products, especially those used at high temperatures or exposed to prolonged sunlight. The typical usage level is 0.25%–0.5%. This product exhibits low color contribution and chelating effects on dyes in polyolefins, improving dyeing results. It has broad application prospects in agricultural films, outdoor plastic products, packaging materials, and more.

Industry Advantages: One-Stop Services, Global Network

Neostar United's core competitiveness lies in its one-stop CRO/CDMO service model spanning the entire product lifecycle. From small-scale laboratory R&D and pilot-scale scale-up to commercial mass production, the company offers flexible process route design and optimization services tailored to client needs at different stages, helping customers shorten R&D cycles and reduce production costs to achieve true win-win collaboration.

In terms of global expansion, Neostar United has established an extensive marketing network covering over 80 countries and regions worldwide, forming long-term, stable partnerships with internationally renowned pharmaceutical and chemical companies. Meanwhile, the company places high importance on sustainable development, striving to build an environmentally friendly green chemical enterprise through technological innovation, harmonizing corporate profitability with social responsibility.
