Chemical Name and CAS Registry Number
- Almond oil [8007-69-0]
Empirical Formula and Molecular Weight
Almond oil consists chiefly of glycerides of oleic acid, with smaller amounts of linoleic and palmitic acids. The PhEur 6.0 describes almond oil as the fatty oil obtained by cold expression from the ripe seeds of Prunus dulcis (Miller) DAWebb var. dulcis or Prunus dulcis (Miller) DAWebb var. amara (DC) Buchheim or a mixture of both varieties. A suitable antioxidant may be added.
The USP32–NF27 describes almond oil as the fixed oil obtained by expression from the kernels of varieties of Prunus dulcis (Miller) D.A. Webb (formerly known as Prunus amygdalus Batsch) (Fam. Rosaceae) except for Prunus dolcii (Miller) D.A. Webb var. amara (De (Andolle) Focke).
- Emollient; oleaginous vehicle; solvent.
Applications in Pharmaceutical Formulation or Technology
Almond oil is used therapeutically as an emollient and to softener wax. As a pharmaceutical excipient it is employed as a vehicle in parenteral preparations, such as oily phenol injection. It is also used in nasal spray, and topical preparations. Almond oil is also consumed as a food substance.
