Dmp Phthalate Uses

1. Plastics and resin industry
Plasticizer: As an efficient plasticizer, Dmp Phthalate is mainly used to improve the flexibility and processability of cellulose acetate, nitrocellulose, polyvinyl chloride (PVC) and various other cellulose resins and vinyl resins. and low temperature performance. It has good compatibility with these resins and can improve their film-forming, adhesion and waterproof properties. It is often used in the production of films, varnishes, transparent papers, molding powders and other products.

2. Rubber industry
Rubber softener: Dmp Phthalate can increase the plasticity of rubber, especially for nitrile rubber and neoprene. It can significantly improve the processing performance of the rubber. However, considering its volatility and low-temperature crystallization, it is usually combined with other plasticizers. agent mix to optimize performance.

3. Coatings and printing inks
Solvents and diluents: In coating and ink formulations, Dmp Phthalate can be used as a solvent for polyvinyl fluoride coatings, gas chromatography fixatives and some special inks, helping to improve the solubility and fluidity of materials, making coating or printing The effect is more even and long-lasting.

4. Pharmaceutical and personal care products
Solvents and Stabilizers: In the pharmaceutical field, DMP can be used as a raw material for manufacturing medical tapes, packaging materials, syringes and other medical devices, and as a high-boiling point solvent in personal care products such as perfumes and essences, providing good stability and ductility. Due to safety concerns, its application in these areas is gradually being restricted.

5. Protection and Specialty Chemicals
Mosquito repellent: Dmp Phthalate can be used as a component of mosquito repellent oil because of its mosquito repellent effect. It can also be used as a stabilizer for methyl ethyl ketone peroxide (MEKP, an unsaturated polyester resin curing agent), as well as the historical DDT ( DDT) solvent.

Prominent Applications of Dmp Phthalate in Cosmetics

Dispersant and stabilizer for flavors and fragrances:
Dmp Phthalate has good solubility and can effectively dissolve a variety of flavor and fragrance ingredients, so it is used as a dispersant in perfume manufacturing. It helps flavors and fragrances mix evenly, avoids stratification or precipitation, and ensures the stability of perfumes. At the same time, due to its low volatility, DMP can slow down the volatilization rate of flavors and fragrances, making the fragrance of perfumes more lasting and enhancing the consumer’s experience.

Adjust product texture:
In some cosmetics such as hair spray and skin care products, Dmp Phthalate can form a thin and flexible film, giving the product a better touch without adding greasiness. This film helps protect hair from stiffness, while increasing the permeability of skin care products to the skin, making the product easier to be absorbed by the skin, and improving the comfort and effect after use.

Solvent effect:
As an organic solvent, Dmp Phthalate can help other insoluble active ingredients in cosmetic formulas better integrate into the system, improving the compatibility and integrity of the formula. This property is essential to ensure the uniformity and stability of cosmetic formulas.

Improve product physical properties:

Although Dmp Phthalate is not used as a plasticizer in cosmetics as its similar substance DBP is used in nail polish, it can also improve the physical properties of certain cosmetics through a slight plasticizing effect, such as reducing brittleness and increasing flexibility, which helps to ensure the durability and ease of application of cosmetics during use.
