Uses in Perfume
Benzyl methacrylate has found some use in perfume
compositions where it may introduce very
desirable notes in Rose and other floral fragrances, in Chypre, Oriental and heavy woody
fragrance types, etc.
It blends excellently with Oakmoss, Vetiver,
Phenylacetaldehyde dimethylacetal, Citrcnel101,as well as with Lavender, Lavandin, Spike
Lavender, etc. The ester is also used in soap
and detergent perfumes, where its low cost
allows for a more liberal application.
Description
The cyclic methacrylate monomer benzyl methacrylate (BzMA) was evaluated as an alternative to traditional methyl methacrylate (MMA) as a hard monomer in the application of an acrylate latex pressure-sensitive adhesive (PSA). BzMA is widely used in nanoimprinting lithography, paint applications, inkjet inks, transparent adhesives, orthodontic adhesive compositions, and stationary phases in liquid chromatography[1].
Chemical Properties
Colorless oily liquid.
Very slightly soluble in water, soluble in
alcohol and oils.
Soft, warm, herbaceous-rosy odor of moderate tenacity.
Uses
Benzyl methacrylate is an important raw material and intermediate used in organic synthesis, pharmaceuticals and agrochemicals.
Flammability and Explosibility
Not classified
Advantages
The Tg of the copolymer was elevated, while thermal stability was first increased and then decreased with the introduction of Benzyl methacrylate. Besides, the water resistance of the latex PSA was improved by the presence of BzMA, which was confirmed by water contact angle measurements. Furthermore, as the BzMA content increased, the gel content slightly decreased, while sol molecular weight (Mw, Mn) of the polymer increased. Finally, with respect to the adhesive properties of the PSA, it was observed that loop tack decreased, while shear strength increased with the incorporation of BzMA. 180° peel strength initially increased and then decreased with the addition of Benzyl methacrylate from 0 to 30 wt%, with a maximum value at 5 wt%.
