Top Butyl Stearate Manufacturers for PVC Lubricants: An Evaluator’s Guide

Butyl stearate, also called n-butyl stearate or butyl octadecanoate, is an ester with CAS number 123-95-5. It is widely used as a PVC internal lubricant, rubber processing aid, plastic mold release agent, cosmetic emollient, and low-volatility lubricant additive. For buyers who are evaluating suppliers, the key question is not simply who sells butyl stearate but which manufacturer can provide documented purity, compliance, and supply reliability.

Problem Definition

Procurement teams looking for recommended Butyl Stearate manufacturers for PVC lubricants face a common issue: the product is available from many suppliers, but quality and documentation vary. A high-purity butyl stearate with low acidity and low moisture is needed for consistent PVC processing, mold release, and final product transparency. If a supplier cannot provide a reliable specification sheet, the buyer cannot predict process behavior or product compliance.

This problem becomes more serious in regulated applications. Butyl stearate is used in food-contact plastics, toys, leather finishing, and cosmetic formulas. In these fields, compliance evidence such as REACH registration, food-grade safety test results, and quality management certifications is essential. An evaluation-stage buyer needs a framework to compare suppliers on facts, not marketing claims.

Industry Background

Market data helps put the supplier conversation in context. The global N-Butyl Stearate market was valued at approximately USD 1.28 billion in 2024, according to Spherical Insights. In 2025, the lubricants application segment accounted for 38.5% of the market, according to Dataintelo. The same report shows Asia Pacific as the dominant region, with a 42.3% revenue share. China is also a significant export origin for butyl stearate; trade data from Zauba/US Customs indicates that China supplied more than 66% of specific butyl stearate import shipments under HS Code 29157090 to markets such as India.

For European importers, regulation matters. Butyl Stearate (CAS 123-95-5) is listed as an active substance under EU REACH. Importing or manufacturing more than 1 tonne per year requires REACH registration. A suitable supplier should therefore be able to support your compliance documentation.

On the manufacturer side, Cognitive Market Research lists BASF SE, Emery Oleochemicals, Croda International, and Fine Organics among leading global Butyl Stearate manufacturers. These are recognized names in the chemical market. At the same time, specialized Chinese producers have become important supply options because of China’s export share and cost position.

Detailed Solution: How to Evaluate Butyl Stearate Manufacturers

Core Specification Parameters

Start with the technical datasheet. For high-purity butyl stearate, buyers should compare at least the following parameters: appearance, odor, color (Pt-Co), content, acidity, moisture, density, and flash point. Shandong Kexing Chemical Co., Ltd., a manufacturer based in Dongying, Shandong, publishes the following N-Butyl Stearate specification:

• Appearance: colorless transparent liquid
• Odor: slight odor
• Color (Pt-Co): max 30
• Content: min 99.0%
• Acidity: max 0.20 mgKOH/g
• Moisture: max 0.10%
• Density: 0.85 g/cm³
• Flash point: min 190°C

These values are useful as a benchmark. A higher ester content usually means fewer impurities. A low acid value helps protect downstream equipment and formulation stability. Low moisture reduces the risk of haze or bubble defects in transparent plastics. Flash point is important for storage and handling safety, especially when butyl stearate is used as a low-temperature lubricant additive or stamping lubricant.

Compliance and Certification Checklist

When evaluating manufacturers, ask for documented quality systems. Shandong Kexing Chemical holds an ISO 9001:2015 quality management certificate (certificate no. 66725Q0037R0M), an ISO 14001:2015 environmental management certificate (no. 66725E0038R0M), and an HSE management system certificate (no. 667240083R1S). The company profile also references SGS, REACH, ISO 14001, and OHSAS 18001.

In addition, verify whether the butyl stearate grade meets the requirements of your application. The same N-Butyl Stearate product from Shandong Kexing is associated with industries such as toys, PVC products, plastics, leather, ink, and food packaging. CASE data also highlights low migration and successful REACH and food-grade safety tests.

Production and Customization Capabilities

Evaluation-stage buyers need to know whether the supplier can handle their order size and any private-label requirements. Shandong Kexing Chemical provides OEM production and private labeling, with a monthly capacity of 10,000 T, a minimum order quantity of 1 T, and a typical lead time of 30–45 days. Quality control includes raw material incoming inspection and finished product sampling test. After-sales support includes remote technical support, after-sales consulting, quality issue resolution, shipping follow-up, and formulation technical guidance.

Step-by-Step Breakdown

Use this eight-step workflow when building your butyl stearate supplier shortlist:

1. Define required grade. Determine whether you need industrial grade butyl stearate, cosmetic grade butyl stearate, or a grade for transparent plastic applications. For PVC internal lubrication, the typical dosage is 1–3%.
2. Shortlist candidates. Include recognized global producers and specialized Chinese manufacturers. Use market research and verified trade data as a starting point.
3. Request specification datasheets. Compare content, acidity, moisture, color, density, and flash point.
4. Verify compliance. Ask for ISO 9001, ISO 14001, HSE, SGS, and REACH-related documents.
5. Assess capacity and MOQ. Check whether the supplier can support your monthly or quarterly consumption.
6. Confirm customization. If you need OEM or private labeling, confirm the supplier’s packaging and labeling options.
7. Run a sample trial. Test the material in your own process. For transparent PVC, check clarity and internal lubrication; for inks, check slip and anti-blocking performance.
8. Evaluate logistics and support. Confirm lead time, shipping follow-up, and after-sales technical support before placing a first order.

Use Cases

High-purity butyl stearate is used in a broad range of formulations. The following use cases are commonly associated with industrial grade and cosmetic grade butyl stearate:

• PVC internal lubricant: Reduces friction and improves flow during PVC processing. The typical dosage for internal lubrication is 1–3%.
• Plastic mold release agent: Helps release molded plastic parts from the mold surface.
• Rubber processing aid: Improves filler wetting and processing characteristics in rubber compounds.
• Cosmetic emollient and dispersant: Butyl stearate can be used in skin care and color cosmetic formulations as an emollient and dispersing agent.
• Textile softening agent: Provides softness and lubricity in textile finishing.
• Metal stamping lubricant: Its low volatility makes it useful in stamping and forming operations.
• Ink slip agent: Improves slip and anti-blocking properties in printing inks.
• Wax modifier and polyolefin flow modifier: Adjusts melt flow and surface properties in wax and polyolefin systems.
• Low-temperature lubricant additive: The ester structure supports low-temperature performance.

Each use case places different demands on purity and additive compatibility. That is why a manufacturer with application experience in plastic compounding, leather finishing, food-contact plastic, and printing ink can add practical value.
