Question 1

Is OPE-105 (octylphenol polyoxyethylene ether) harmful to the human body? Does it have an impact on the environment?

Accepted Answer

OPE-105 (octylphenol polyoxyethylene ether) has clear hazards to the human body, especially causing severe damage to the eyes. At the same time, it also has long-term and continuous toxic effects on the aquatic ecological environment. Strict protection must be taken and it is forbidden to discharge it into the environment. Detailed Explanation OPE-105 is a nonionic surctant. According to its Safety Data Sheet (SDS) and GHS classification standards, this product has multiple health and environmental hazards. In terms of human health, the risk of severe eye damage from OPE-105 is the most prominent (Category 1). Once it contacts the eyes, it can cause serious and irreversible damage. At the same time, skin contact can cause irritation reactions, and accidental swallowing is harmful to the body. Therefore, chemical safety goggles, protective gloves, and protective clothing must be worn throughout the operation. In terms of the environment, OPE-105 has obvious acute toxicity and chronic long-term effects on aquatic organisms (H411). This means that even low-concentration discharges may harm fish, aquatic invertebrates, and algae. Moreover, it is not easily and quickly degradable in the environment and has persistent hazards. The product database clearly stipulates: It is strictly forbidden to discharge this product or its wastewater into water bodies, soil, and drainage systems. Spills and cleaning wastewater must be collected as hazardous waste and disposed of by qualified professional institutions. It should be specifically pointed out that octylphenol, as the hydrophobic group in OPE-105, and its environmental degradation intermediates (such as octylphenol itself) are known environmental endocrine disruptors. Even at extremely low concentrations, they may have estrogen-like effects on aquatic organisms. This characteristic further strengthens the necessity of strictly controlling its environmental emissions.

Question 4

Does OPE-105 (opep-105) meet environmental protection requirements? Can a test report be provided?

Accepted Answer

# There is currently no specific environmental protection test report information for the product. The following is an objective analysis of environmental compliance based on the product's Safety Data Sheet (SDS) and hazard classification: OPE-105 poses aquatic toxicity risks, is not classified as an environmentally friendly product, and requires strict emission control. An independent environmental test report is currently not available. Detailed Explanation According to the hazard classification in the product's Safety Data Sheet (SDS), OPE-105 (Octylphenol polyoxyethylene ether) is clearly classified as Aquatic Acute Toxicity Category 2 and Aquatic Chronic Toxicity Category 2, with the hazard statement H411: Toxic to aquatic life with long-lasting effects. This means that if the product is discharged directly into water bodies without treatment, it will cause substantial harm to aquatic ecosystems such as fish, algae, and plankton, and its degradation products may be environmentally persistent. From a molecular structure perspective, OPE-105 belongs to the alkylphenol polyoxyethylene ether (APEO) class of compounds. It is particularly noteworthy that octylphenol polyoxyethylene ether may slowly degrade in the environment and release octylphenol — a known endocrine disruptor (environmental hormone) with estrogenic effects, which can adversely affect the reproductive systems of aquatic organisms even at very low concentrations. Therefore, international chemical management systems, including the EU REACH regulation, have imposed increasingly stringent restrictions on the use and emission of APEO substances. In 2021, the EU added octylphenol to the candidate list for Annex XIV (list of substances subject to authorization) of the REACH regulation. Our company, Guoli Chemical, currently does not have an independent third-party environmental test report or RoHS\/REACH compliance certificate for this product that can be provided online. To obtain the latest environmental compliance documents or specific project test data, it is recommended to directly contact our company's technical department or sales representative for dedicated follow-up. We will assist in evaluating compliance pathways based on your specific application scenario and the regulatory requirements of your target market.

Question 8

How to use OPE-105 (opep-105)? What is the recommended addition amount?

Accepted Answer

OPE-105 is a nonionic surctant. The specific addition amount varies depending on the application scenario. The Guoli Chemical database does not specify a standard dosage, but based on the HLB value (13.5) and industry common practice, the typical addition amount ranges from 0.1% to 10%, requiring experimental optimization to determine the optimal ratio. Detailed Description OPE-105 (Octylphenol polyoxyethylene ether) is a high-purity (active content ≥98%) nonionic surctant, appearing as a colorless to pale yellow viscous liquid at room temperature (viscosity 200~400 mPa·s, 25°C). Due to its moderate but somewhat sticky viscosity, it is recommended to preheat or stir with warm water (40~50°C) before use to enhance fluidity for accurate measurement and subsequent dispersion and dissolution. The product is readily soluble in water and organic solvents, and can be directly dissolved by adding water with stirring, or pre-dissolved in alcohols, ketones, and other solvents before adding to the aqueous system. The determination of the addition amount should comprehensively consider ctors such as the HLB requirement of the target system, type of oil phase, emulsion stability requirements, and cost control. OPE-105 has an HLB value of 13.5, making it a hydrophilic O\/W type emulsifier, suitable for emulsifying highly polar oil phases or used in combination with low HLB emulsifiers. It is recommended to start from low concentrations and gradually increase during the formulation development stage, using surce tension (1% aqueous solution: 30~32 mN\/m) and cloud point (1% aqueous solution: 65~75°C) as reference indicators to determine if the dosage achieves optimal performance. Excessive use not only increases costs but may also cause foaming issues or affect the physical and chemical properties of the final product. Typical Addition Amounts by Application Field The following typical dosage ranges are based on industry application experience; specific amounts should be determined through sample verification according to actual processes and formulation systems: Application Field Functional Role Recommended Addition Amount (as % of working solution\/formulation) Usage Instructions Textile scouring penetrant Penetration, emulsification 0.5~2.0 g\/L Add directly to desizing\/scouring bath; can be combined with anionic auxiliaries Industrial degreasing cleaner Emulsification, detergency 2%~8% Combined with alkaline agents (e.g., sodium carbonate, sodium silicate) for better performance Metalworking fluids (cutting\/grinding) Lubrication, emulsification 1%~5% Used as an emulsifier component in combination with base oils, rust inhibitors, etc. Pesticide emulsifiable concentrate\/emulsion in water Emulsification 5%~15% Combined with anionic emulsifiers (e.g., calcium salt); dosage depends on technical material properties Pesticide suspension concentrate (SC) Wetting, dispersion 1%~4% Used as a dispersing aid in synergy with polymeric dispersants Leather degreasing Penetration, emulsification 0.5%~2% (based on leather weight) Add to drum and mix with water; suitable for raw hides and wet blue degreasing Paper deinking Collection, dispersion 0.1%~0.5% (based on oven-dry pulp) Add during pulping or flotation stage; combine with sodium hydroxide, sodium silicate, etc. Paint\/ink wetting and dispersion Wetting, stabilization 0.1%~1% (based on total formulation) Add during grinding and dispersion stage to promote pigment wetting Antistatic treatment Moisture absorption, conductivity 0.5%~2% Apply by impregnation or spraying onto fibers, plastics; activate after drying Data Explanation: The above dosage ranges are industry general recommendations; the Guoli Chemical product database does not have specific standard dosages for each field. It is recommended that users conduct small-scale tests before formal production, evaluating indicators such as surce tension, wetting time, and emulsion stability to determine the optimal dosage. Combination and Other Usage Suggestions OPE-105 is a nonionic surctant; due to its nonionic nature, it can be widely combined with anionic, cationic, and other nonionic surctants, producing synergistic effects. For example, in degreasing cleaning formulations, combining with anionic LAS and AES can improve detergency and salt tolerance; in pesticide emulsifiable concentrates, combining with calcium dodecylbenzene sulfonate (emulsifier 500#) can yield a more stable emulsion system. The product exhibits good chemical stability in acids, alkalis, and hard water, resisting hydrolysis and deactivation, making it suitable for demanding conditions such as high pH (e.g., alkaline cleaners) and low pH (e.g., acidic rust removers). However, its cloud point is 65~75°C (1% aqueous solution); at temperatures near or above the cloud point, the product may precipitate from water and lose intercial activity. Therefore, heating processes should maintain the working solution temperature below the cloud point, or combine with anionic auxiliaries to improve heat resistance. Due to its low-foaming property, OPE-105 offers significant advantages in foam-sensitive processes such as spray cleaning and circulating systems, reducing the need for defoamers. Precautions Dosage Optimization: The optimal addition amount should be determined through surce tension testing, emulsion stability experiments, or actual process performance evaluation; avoid blindly referring to ratios used for similar products. Dissolution Operation: Adding high-concentration product directly to cold water may cause gelation; it is recommended to pre-dilute the product with an appropriate amount of warm water or slowly add it to water with stirring. Safety Protection: This product is harmful if swallowed (H302), causes skin irritation (H315), and causes serious eye damage (H318). Protective gloves, goggles, and protective clothing must be worn during operation; use in well-ventilated areas. For detailed safety information, refer to the Safety Data Sheet (SDS). Environmental Requirements: This product is toxic to aquatic life with long-lasting effects (H411). Wastewater and residues must be collected and disposed of by qualified hazardous waste treatment agencies; do not discharge into water bodies or soil. Storage Requirements: Store at 0~30°C, keep containers tightly closed, avoid direct sunlight and drastic temperature fluctuations, and keep away from strong oxidizers and strong acids\/alkalis.

It is an indispensable nonionic surctant in many industrial formulations. Detailed Description OPE-105 is a nonionic surctant with octylphenol as the hydrophobic group, modified with 10.5 EO (ethylene oxide). With excellent emulsifying ability, outstanding wetting and penetrating performance, and a wide range of chemical resistance, it maintains stable intercial activity under acidic, alkaline, and high-hardness water conditions, making it a key functional additive in multiple industrial fields. This product can be used in combination with anionic, cationic, and other nonionic surctants for synergistic enhancement, flexibly adapting to different process formulation needs. Its appearance ranges from colorless to light yellow transparent liquid or flowable paste, cilitating precise dosing and compounding. Application Industries and Processes Overview Industry Process/Application Function Description Textile Industry Scouring Penetrant During desizing and scouring of cotton, linen, and other fibers, it rapidly penetrates and emulsifies waxes and oils, improving capillary effect and whiteness, creating a uniform foundation for subsequent bleaching and dyeing. Leveling Agent Promotes uniform dye uptake, prevents color spots and shading, and improves the first-time dyeing success rate. Metalworking Cutting/Grinding/Stamping/Drawing Lubricants Forms a high-strength lubricating film, reduces friction coefficient, carries away processing heat, and extends tool and mold life. Rust Preventive Fluids In water-based rust prevention systems, it adsorbs onto metal surces forming a protective layer, effectively isolating oxygen and moisture, suitable for inter-process and short-term storage rust prevention. Industrial Coatings As a wetting and dispersing component in water-based or solvent-based coatings, it promotes pigment wetting, prevents floating and flooding, and improves film adhesion.

Pesticide Formulations Emulsifiers (EC/EW) Enables oil-soluble active ingredients to spontaneously disperse in water, forming stable emulsions, improving wetting and spreading of the active ingredient, and enhancing efficacy. Dispersants (SC/WP) Prevents pesticide particles from agglomerating and settling, maintains long-term storage stability of the formulation, and improves suspension rate after dilution. Leather Processing Hide Degreasing Agent Penetrates between leather fibers to emulsify natural ts, achieving uniform degreasing, improving leather softness and dyeing uniformity. Paper Industry Deinking Agent In waste paper recycling deinking processes, it combines with ink particles, and through flotation or washing methods, separates ink from fiber surces and suspends it for removal, improving pulp whiteness. Antistatic Agent Coated or impregnated on synthetic fibers and plastic surces, it reduces surce resistance, accelerates static charge dissipation, and reduces dust attraction, static shock, and spark risks during production and use. Application Recommendations The recommended concentration of OPE-105 in different processes is typically 0.1%–5.0% (based on total working fluid volume). The specific dosage should be determined experimentally based on oil phase type, water hardness, temperature, and formulation system. It is recommended to conduct compatibility and stability tests during the formulation development stage to fully utilize its synergistic effects with anionic, cationic, and other nonionic surctants for optimal cost-effectiveness. Precautions Safety Risks: Harmful if swallowed (H302), causes skin irritation (H315), causes serious eye damage (H318), and is toxic to aquatic life (H411).
