SECTION 1: PRODUCT IDENTIFICATION AND CHEMICAL IDENTITY

PRODUCT DESCRIPTION AND EXPLANATION:

Texanol (2,2,4-trimethyl-1,3-pentanediol monoisobutyrate) is a coalescing (film-forming) aid widely used in the paint and coatings industry. In water-based latex paints, it promotes the fusion of polymer particles to form a continuous and uniform film.

Texanol is recognized for its low volatility, high boiling point, and broad compatibility with latex systems. It lowers the minimum film formation temperature (MFFT) of latex paints, ensuring quality film formation even at low temperatures. After the paint dries, it slowly evaporates, allowing the film to regain its hardness and durability.

SECTION 2: PHYSICAL AND CHEMICAL PROPERTIES

PHYSICAL AND CHEMICAL PROPERTIES EXPLANATION:

Texanol is a colorless to light yellow liquid at room temperature with a mild ester-like odor. Its density is 0.95 g/cm³, making it lighter than water and it floats on the water surface. The boiling point ranges from 255-260°C, indicating a high boiling point. The vapor pressure at 20°C is very low (1.3 Pa), making it a low-volatility substance.

It shows limited solubility in water (~2 g/100 mL) but is miscible with many organic solvents. Since its flash point is above 120°C, it is not classified as a flammable liquid under normal conditions, but it can form flammable vapor mixtures at high temperatures. The Log Pow value of 3.47 indicates a moderately lipophilic substance.

SECTION 3: CHEMICAL PROPERTIES AND REACTIONS

CHEMICAL PROPERTIES EXPLANATION:

Texanol is an ester compound. Esters react with acids to release heat and may react violently with strong oxidizing acids. Heat is also released from the interaction of esters with caustic solutions. When esters are mixed with alkali metals and hydrides, flammable hydrogen gas can be generated.

SECTION 4: APPLICATION AREAS

APPLICATION AREAS EXPLANATION:

Paint and Coating Coalescent: The primary use of Texanol is as a coalescing (film-forming) aid in water-based latex paints. During the film formation process of latex paints, polymer particles need to be soft enough to fuse. Texanol is absorbed by the polymer particles, temporarily plasticizing them and lowering the minimum film formation temperature (MFFT). After the film is formed, Texanol slowly evaporates, allowing the paint film to regain its original hardness and durability.

Emulsion Performance Enhancer: Used as a performance enhancer in water-based paints and emulsions. It is an effective coalescent for a wide range of latexes including acrylic, styrene-acrylic, and polyvinyl acetate (PVA) latexes.

Chemical Intermediate: Texanol is used as a chemical intermediate in plasticizer production.

SECTION 5: HEALTH AND SAFETY

HEALTH AND SAFETY EXPLANATION:

Texanol is a substance with limited inhalation risk due to its low volatility. It may cause mild irritation upon skin contact and may cause irritation upon eye contact. Ingestion may cause gastrointestinal discomfort.

Safety Precautions:

• Inhalation: Risk of inhalation is low under normal conditions. Respiratory protection may be required in case of aerosol formation.

• Skin Contact: Avoid skin contact. Protective gloves should be used.

• Eye Contact: Avoid eye contact. Safety goggles should be used.

• Ingestion: Do not ingest. Seek medical attention if swallowed.

• PPE Recommendations: Safety goggles, protective gloves, protective clothing.

• Environmental: Since it is harmful to aquatic life, it should not be released into the environment.

SECTION 6: STORAGE AND TRANSPORT

STORAGE AND TRANSPORT EXPLANATION:

Texanol should be stored in cool and well-ventilated areas. Keep away from heat and direct sunlight. Store in original, closed packaging. Avoid contact with strong oxidizing agents, strong acids, and strong bases.

Transport Classification: Texanol is not classified as a hazardous substance under ADR/RID (low risk profile). However, care should be taken not to release it into the environment in case of spillage.

Packaging: Shipped in metal drums, IBC tanks, or suitable solvent containers.

SECTION 7: FIRE FIGHTING MEASURES

FIRE FIGHTING MEASURES EXPLANATION:

Texanol is a combustible liquid with a flash point above 120°C. In case of fire, extinguish with powder, AFFF, foam, or carbon dioxide. In case of fire, irritating and toxic gases such as CO and CO₂ may be formed. Self-contained breathing apparatus should be used during fire fighting.

SECTION 8: ACCIDENTAL RELEASE MEASURES

ACCIDENTAL RELEASE MEASURES EXPLANATION:

In case of spillage, collect the leaking and spilled liquid in closable containers as much as possible. Absorb the remaining liquid in sand or inert absorbent. Then store and dispose according to local regulations. This chemical must not be allowed to enter the environment.

SECTION 9: FIRST AID MEASURES

FIRST AID MEASURES EXPLANATION:

• Inhalation: Move to fresh air.

• Skin Contact: Remove contaminated clothing immediately. Wash skin with water and soap.

• Eye Contact: First rinse with plenty of water for several minutes (remove contact lenses if possible), then seek medical attention.

• Ingestion: Do not ingest. Seek medical attention if swallowed.

SECTION 10: REGULATORY INFORMATION

REGULATORY INFORMATION EXPLANATION:

Texanol is registered in major industrial markets such as the EU (REACH) and USA (TSCA). It has been granted a pesticide tolerance exemption by the US EPA. In Türkiye, it requires mandatory registration under KKDİK.

SECTION 11: SUMMARY AND CRITICAL NOTES

SUMMARY:

Texanol (2,2,4-trimethyl-1,3-pentanediol monoisobutyrate, CAS 25265-77-4) is a coalescing (film-forming) aid widely used in the paint and coatings industry. It is a colorless to light yellow liquid with a mild ester-like odor. Its molecular weight is 216.32 g/mol, density is 0.95 g/cm³, boiling point is ~254°C, and flash point is 120-121°C.

Texanol promotes the fusion of polymer particles in water-based latex paints to form a continuous and uniform film. It lowers the minimum film formation temperature (MFFT) of latex paints and allows the film to regain its hardness after drying. It is also used in adhesives, polymers, printing inks, and as a chemical intermediate.

Due to its low volatility, inhalation risk is limited. It may cause mild irritation upon skin and eye contact. It is harmful to aquatic life. Store in cool, well-ventilated areas, away from heat and direct sunlight. It is not classified as a hazardous substance under ADR/RID.

Main Application Areas:

Key Safety Points:

• LOW RISK: GHS Warning; H316 (Mild skin irritation), H402 (Harmful to aquatic life)

• INHALATION: Risk limited due to low volatility

• SKIN: May cause mild irritation; use protective gloves

• EYE: May cause irritation; use safety goggles

• ENVIRONMENT: Harmful to aquatic life; do not release into the environment

• STORAGE: Cool, well-ventilated, away from heat and sunlight

CRITICAL NOTES:

1. Coalescent Mechanism of Action: Texanol is absorbed by polymer particles in latex paints, temporarily plasticizing them and lowering the minimum film formation temperature (MFFT). After the film is formed, it slowly evaporates, allowing the film to regain its hardness.

2. Broad Latex Compatibility: Texanol is an effective coalescent for a wide range of latexes including 100% acrylic, styrene-acrylic, and polyvinyl acetate (PVA) latexes. Harder polymers generally require higher coalescent concentrations.

3. Low Volatility: The vapor pressure at 20°C is very low (1.3 Pa). This property limits inhalation risk and provides long-term film formation performance.

4. Limited Water Solubility: It has a solubility of ~2 g/100 mL in water. This provides suitable phase behavior in latex systems.

5. Environmental Impact: It is harmful to aquatic life. Care should be taken not to release it into the environment in case of spillage.

6. Flammability: Since its flash point is above 120°C, it is not classified as a flammable liquid under normal conditions, but it can form flammable vapor mixtures at high temperatures. Keep away from heat sources.
