Diisopropyl adipate is a colorless, transparent liquid at room temperature and pressure, and is soluble in common organic solvents. It has the versatility and special aroma of esters. It is widely used in medicine, fragrances and daily chemical products, and can also be used as a cold-resistant plasticizer for synthetic cellulose resins and rubber.
Diisopropyl adipate CAS 6938-94-9 Use
I. Core use: efficient solvents and carriers
Solvents for cosmetics and personal care products:
Used in sunscreens, lotions, and lipsticks to dissolve oily active ingredients (such as avobenzone), improve the lightness of the texture, and avoid stickiness.
Fragrance fixative:
Prolong the release time of volatile fragrance molecules (such as terpenes) in perfumes and enhance the durability of fragrance.
Industrial cleaning agent components:
Replace strong solvents such as acetone and toluene for degreasing and cleaning of precision electronic components (low residue, low toxicity).
II. Polymer material processing aids
PVC auxiliary plasticizer:
Compounded with the main plasticizer (such as DOP) to improve the low-temperature flexibility of PVC film/sheet (anti-brittle cracking at -20℃).
Rubber softener:
Added to styrene-butadiene rubber (SBR) to reduce mixing viscosity and improve processing efficiency (without affecting vulcanization performance).
Coating film-forming aid:
Used in nitro lacquer and acrylic lacquer to promote resin fusion, eliminate brush marks, and improve coating gloss.
III. Chemical reaction medium and intermediates
Pharmaceutical synthesis reaction solvent:
As a low-polarity reaction medium, it is used for crystallization and purification of antibiotics (such as cephalosporins) (high boiling point and easy recovery).
Ester exchange synthesis precursor:
React with long-chain alcohols (such as lauryl alcohol) under acid catalysis to prepare customized plasticizers such as didecyl adipate.
Catalyst dispersion carrier:
Carrying metal catalysts (such as palladium carbon) for hydrogenation reactions to improve catalytic uniformity (not involved in catalysis itself).
Diisopropyl adipate CAS 6938-94-9 safety
Diisopropyl adipate has low toxicity, but care should still be taken to avoid direct contact with skin and eyes when used. Ecological impact: The impact on the environment is small, but it still needs to be handled and used in accordance with relevant environmental protection regulations.
