EL Ethylene lactate is a good bio-based solution derived from natural regenerative resources such as maize or beet fermentation. Not only does it have an excellent solubility, but it is also known for its high biolysis, low-morbidity (Low VOC) and low toxicity, and it is an ideal environmental alternative to traditional oil-based solvents (e.g., toluene, diphenyl or ketone).EL acts as a green solvent in the electronic and semi-conductor industries, mainly for precision cleaning, photoresisting and surface removal, with low toxicity, high solubility and no blemish.。

Solvability
Emulsifiable ethyl esters are known as "gluently-enabled solvents" and their molecular construction contains both thallium (-oh) and esters (-COOR), which are uniquely associated with the two-heavy properties of the water and the oil, which allow them to exhibit a very strong solubility of many natural and synthetic substances.
Advantages
Green and Persistence
In today ' s increasingly stringent ESG and environmental laws, ethyl lactate is the best alternative to oil-based solvents:
- Biological sources: Lactate derived from natural maize, beet or sugar cane fermentation, which is 100% renewable.
- Biodegradability is extremely high: carbon dioxide and water can be rapidly decomposed after discharge into the environment, without harm to aquatic organisms.
- Low-volatile (Low VOC): Effectively reducing atmospheric photochemical response pressure and the risk of air pollution, meeting the certification needs of green factories.
Cleaning and penetrating.
- "All-powerful solubility" characteristics: having a unique dual-organium and esters can at the same time respond to both extreme and non-polar defilement, in particular the extreme dissociation of electro-weldants, photoresistants, ink and grease.
- Low surface tension: it's very well-equipped for perturbation, which allows for a thorough clean-up of tiny cracks (e.g. semi-director seals, high-density PCB blindness).
- The rate of evaporation is moderate: evaporation is stable, it is not acetone-like, it is dry in a moment, and it leaves white spots, and it ensures the leveling and polishing of surfaces.
Security
- Non-cancer and low toxicity: The additives approved by the U.S. FDA as publicly recognized safety (GRAS) are extremely low for respiratory and skin irritation of operators.
- High point (High Flash Point): The flash point is about 53°C, less flammable than acetone and ethanol during industrial storage and transport, reducing the risk of fire and saving the cost of safety insurance.
- The fragrance of the fragrance: with a little fragrance, it can improve the working environment of the factory, and away from the chemical smell of snotting.
Use Help
Semiconductor and electrical industries
- Photoresistor dilution and removal (EBR): As a edge cleaner (Edge Head Remover), it is precise to remove much of the photoresistance at the edge of the crystal circle and does not damage the base.
- PCB Welding Cleaning: The fragrance of cedars and ointment after welding has been effectively dissolved, preventing circuit boards from decaying and short circuits.
- Precision element delipidation: Pre-encapture testing is used to remove trace oils and dust from the surface of electrical parts.
General industrial use
- Fluid application: Controls the speed at which the coating is dry, prevents paint membranes from creating condensed holes or bubbles, and increases surface glossiness.
- Wire-printed ink: good solubility keeps the ink stable and reduces web blockage.
- Special glue soluble: Should be used for pressure sensitive or precision adhesive glue to provide stable viscosity control.
- Agropharmaceutical emulsifiable concentrate (EC) carries: the high solubility of ethyl lactate carries more active ingredients and its low toxicity reduces the impact on crops and the environment.
- Chemical media: As a reaction medium or extraction in the synthesis of medical products, ensure that the production is in line with Green Chemical.
- Aromatic solvent: often used for the fragrance of fruits such as cream, pineapple and grapes.
- Cosmetics and nail polish: as a solvent in the discharge of nails or in cosmetics, replaces the chemical component of traditional nasal sting and carcinogenic risks.
- Metal oil removal: efficient and non-flammable clean-up programmes for heavy oil contamination and cutting oil after metal processing.
- Simulator cleanness: Cleaning of resin residue on the surface of the emulsion, non-harming mold accuracy.
Security & Save Proposal
Save Conditions
- Environmental Temperature: Saved in a cool, dry and well-ventilated indoor environment. It's recommended that the temperature be controlled. 5°C to 30°C Between.
- Container Selection：
- RecommendedStainless Steel、High-density polyethylene (HDPE) orTeflon (PTFE) Containers.
- Avoiding the use of ordinary carbon steel or beryllium containers, long-term storage may lead to a trace increase in acidity or metal ion distillation (especially when electro-grade demand is required).
- Seal protection.: The product has a weak insinuation and should be maintained when the container is not usedIt's absolutely sealed.to prevent the absorption or oxidation of water in the air.
- Stay away from the source.: Should be far from heat sources, sparks, open fires and flammable articles. Save the area for a strict ban on fireworks.
Operation Environment and Operational Advice
In the case of the use of ethyl lactate in factories or laboratories, it should be noted that:
- Ventilation system: Operational area is well preparedLocal ventilationAlthough the fragrance of the facilities is mild, there is still a need to ensure that air flow is maintained in order to maintain professional hygiene standards.
- Fire protection.: as its flashpoint (approximately 53°C) is within the flammable liquid range, it is recommended to useBomb protectionElectricity and lighting, and make sure it's good.Quiet.。
- Personal Protection (PPE)：
- Hand: with chemical anti-chemical piercing gloves (e.g. nitrile or butyl).
- Eyes.(b) With protective glasses or masks to prevent liquid glucose.
- Breathe.: In a high-intensity mist environment, an organic vapour protection mask should be worn.
- ProhibitionThe area of operation is severely closed to food, water or smoking; the operation should be followed by a thorough cleaning of hands.
Transport Recommendations
- Transport Category: According to the International Dangerous Goods Shipment Regulation (IMDG/IATA), lactate is usually classified as Flammable liquid type 3 (Flammable Liquid)。
- UN NumberUN 1192
- Package type:III (low risk)
- Sunproof against heat.: Transport vehicles should be equipped with sun-shield measures to avoid sunlight, and should be careful to avoid high-temperature periods during the summer.
- Load up.: The discharge shall be light, with a strict ban on impacting, frictioning or reversing, and to prevent leakage due to damage to the package.
- Emergency preparedness.: Transport vehicles should be equipped with a range and quantity of fire-fighting equipment (e.g., dry powder extinguishers) and leaking emergency handling equipment.
