OEM High-Purity Butyl Stearate: Supplier Capability Guide

A procurement team looking for an OEM high-purity Butyl Stearate manufacturer needs more than a product name. It needs a supplier that can maintain 99% minimum purity, support private-label requirements, provide regulatory documentation, and deliver export orders without disrupting production. Shandong Kexing Chemical Co., Ltd. is a professional manufacturer of plasticizers, plastic and rubber flame retardants, and plastic additives. Its N-Butyl Stearate, also called n-Butyl Stearate or Butyl Octadecanoate, is produced under CAS 123-95-5 and used in PVC processing, personal care, lubricants, textiles, and inks. This guide explains the supplier capabilities that matter and how to move from evaluation to order.

The Sourcing Problem: Purity, Consistency, and Certification

Butyl Stearate appears in many formulations under several names, including Butyl Octadecanoate and n-Butyl Stearate. Buyers usually search for High Purity Butyl Stearate when they need an industrial or cosmetic-grade material with low color, low moisture, low acidity, and high ester content.

In PVC and rubber processing, the material acts as a PVC internal lubricant, plastic mold release agent, rubber processing aid, transparent plastic additive, polyolefin flow modifier, and wax modifier. In personal care, it works as a skin care emollient and cosmetic dispersant. Textile and printing ink producers use it as a textile softening agent and ink slip agent. Metalworking buyers use it as a metal stamping lubricant and low-temperature lubricant additive.

The main sourcing risk is not finding the chemical; it is finding a supplier whose batch quality and documentation match the declared specification. A true manufacturer should be able to show production facilities, quality-control procedures, export experience, and a test report for every batch. A trader or broker may not offer the same traceability or OEM flexibility.

Industry Background: The High-Purity Butyl Stearate Market

The global N-Butyl Stearate market was estimated at approximately USD 1.28 billion in 2024, according to Spherical Insights. In 2025, lubricants accounted for the largest application segment with 38.5% market share, and Asia Pacific held 42.3% of regional revenue, according to Dataintelo. China is a major export source: customs-based trade data shows China supplied more than 66% of specific Butyl Stearate import shipments under HS Code 29157090 to markets such as India.

On the regulatory side, Butyl Stearate (CAS 123-95-5) is listed as an active substance under EU REACH, and imports or manufacture above one tonne per year require registration. Buyers should therefore ask for REACH-related evidence as part of supplier qualification.

Market research identifies BASF SE, Emery Oleochemicals, Croda International, and Fine Organics among the leading global manufacturers. For buyers evaluating OEM supply in China, the question is not whether global brands exist, but whether a Chinese manufacturer can match specification, compliance, and service requirements.

Detailed Solution: What an OEM High-Purity Butyl Stearate Manufacturer Needs to Prove

Production and company background

Shandong Kexing Chemical Co., Ltd. was founded in 2006 and is based in Dongying, Shandong Province, China. The company has 200 employees, an R&D team of 15 engineers, and an annual output of 20,000 units. It manufactures a broad portfolio of plasticizers and plastic additives including N-Butyl Stearate, and its subsidiary Dongying Kexing International Trade handles global import and export business. Approximately 50% of production is exported to Europe, USA, Japan, South Korea, and the Middle East.

Shandong Kexing supports OEM programs with an in-house R&D center.

Product specification baseline for N-Butyl Stearate

For OEM procurement, the specification table below is the baseline to check against your own incoming quality acceptance criteria.

The product is supplied in liquid form with slight odor, colorless appearance, and is used across PVC, plastics, leather, ink, toys, and food packaging applications.

OEM and private-label services

OEM production with private labeling is available. A buyer can place an order under its own brand while relying on Kexing's production system. Key metrics include a monthly capacity of 10,000 tonnes and a lead time of 30–45 days. The minimum order quantity is 1 tonne, which makes the arrangement suitable for both trial programs and established monthly volumes.

Quality control follows a documented sequence: raw material incoming inspection, then finished product sampling test. After-sales support includes remote technical support, formulation technical guidance, shipping follow-up, quality issue resolution, and after-sales consulting.

Compliance and certification evidence

Kexing states that all products are certified by SGS, REACH, ISO 9001, ISO 14001, and OHSAS 18001. The management system certificates below are representative of the documentation available for audit.

For EU shipments, verify REACH registration details with the exporter before placing the order.

Step-by-Step Procurement Process for OEM Butyl Stearate

1. Define the application. Identify whether you need industrial or cosmetic grade, and confirm the role: PVC internal lubricant, mold release agent, emollient, or another function.
2. Check the specification and CAS number. Require a specification sheet for N-Butyl Stearate with CAS 123-95-5, purity min 99%, appearance, color, acidity, moisture, density, and flash point.
3. Request compliance documents. Ask for test reports or certificates and confirm REACH/ISO documentation. Because EU REACH registration is required above 1 tonne per year, verify that your intended import volume is covered.
4. Evaluate OEM capability. Confirm private labeling, packaging, capacity, lead time, MOQ, and quality-control sequence.
5. Test with samples. Use the sample in your own compounding line, rubber formulation, or personal-care batch, then compare results against your acceptance criteria.
6. Confirm commercial terms. Kexing's standard terms are MOQ 1 tonne, 30% deposit and 70% payment against bill of lading, delivery under FOB or CIF, with acceptance based on factory test report.
7. Place and schedule the order. Plan around a 30–45 day lead time; for recurring demand, align ordering with the monthly capacity and shipping schedule.
8. Use after-sales support. Keep the supplier involved during scale-up to solve formulation or logistics issues.

High-Purity Butyl Stearate Use Cases Across Industries

1. PVC and plastics processing

Butyl Stearate is used as a non-toxic internal lubricant in PVC processing, typically at 1–3%. It also serves as a plastic mold release agent, rubber processing aid, polyolefin flow modifier, transparent plastic additive, and wax modifier. Its flash point of at least 190°C supports use in processes where low volatility is required.

2. Personal care and cosmetics

In skin care, Butyl Stearate functions as an emollient and dispersant. A cosmetic-grade source should be colorless, low-odor, and non-toxic, which aligns with the N-Butyl Stearate specification above.

3. Textile and ink applications

Textile producers use Butyl Stearate as a softening agent; printing ink manufacturers use it as a slip agent to adjust surface feel and print performance.

4. Lubricants and metalworking

Because of its compatibility with oils and low-temperature behavior, Butyl Stearate is used in metal stamping lubricants and as a low-temperature lubricant additive.

5. Food-contact, toys, and leather-adjacent applications

In plastics and coated materials destined for toys, food packaging, and artificial leather, low migration and regulatory safety are critical. In documented use, plastic masterbatch factories, artificial leather manufacturers, food packaging processors, and toy factories have used the product in plastic compounding, leather surface finishing, and food-contact plastic and printing ink formulation. The product helped improve flexibility, showed low migration, and passed REACH and food-grade safety testing in customer applications.
