What is the ruling on a woman working in a perfume or incense shop or factory?

The basic ruling on a woman working outside her home is permissibility if the work is lawful and free from Sharia (definition) prohibitions such as intermingling (ikhtilat), being alone with men (khalwa (definition)), speaking in a soft or alluring manner (khudu' bil-qawl), displaying one's adornments (tabarruj), going out without her husband's permission, traveling without a mahram (definition), and neglecting family duties. So, if the work in a perfume shop or factory is free from Sharia prohibitions and does not lead to any corruption, then it is permissible.
