Johnson & Johnson stopped selling the first aid back plaster due to concerns over potential safety risks. The plaster contained an ingredient called chrysotile asbestos, which is known to be carcinogenic and can lead to serious health issues such as mesothelioma. Asbestos exposure can result in legal liabilities for the company, as well as damage to its reputation and trust among consumers. Therefore, Johnson & Johnson made the decision to discontinue the product to prioritize consumer safety and mitigate any potential harm.

Back plaster refers to a layer of plaster or mortar applied to the backside of a wall in construction. It is typically used to provide additional strength, support, or insulation to the wall. The back plaster helps to stabilize the wall structure and improve its durability.
Technically it was the Johnson and Johnson company in 1890. They called it the Johnson and Johnson's First Aid Cabinet. Back then, it only contained the bare essentials of a first aid kit.

Sure! But what it probably can't be turned back into is usable plaster. They make plaster by dehydrating gypsum. When you add water to it, the gypsum particles absorb water. Unless you dry the powder you made out, you can't use it again.
Ancient Egyptians used plaster surfaces in palaces and pyramids. This sort of thing was done back in the 16th century.
First you need to recognize that "plaster" is not a singularly defined material; it is a family of quite different materials that harden by different mechanisms. The three most common plasters are (1) Plaster of Paris, (2) Lime Plaster, and (3) Cement Plaster.(1) Plaster of Paris is CaSO4.H2O, a partially-dehydrated form of Gypsum, which is a hydrated Calcium Sulfate crystal CaSO4.2H2O. When Plaster of Paris is mixed with water, it re-hydrates and turns back into Gypsum, which then hardens into a material similar to mortar or concrete but considerably softer. Water is the material that makes Plaster of Paris harden.(2) Limestone When exposed to atmosphere the Calcium hydroxide turns back to limestone, causing the plaster to set.(3) Cement Plaster is a mixture of Portland Cement powder, sand or other filler, water, and either Plaster of Paris or Lime Plaster. Due to the great variety of minerals that makeup Portland Cement and Cement Plaster, the hardening is a complex process that cannot be ascribed to the action of any one of the ingredients.
