Direct answer: Cosmetic pine tar is pine tar used or listed as an ingredient in cosmetic or personal-care products, subject to ingredient rules and product safety requirements.
Pine tar moved from working yards and stables into soaps, shampoos, and specialist personal-care products because of its strong smell, dark colour, and historical associations. Ingredient databases may list specific botanical tars, such as tar obtained from particular pine species.
The phrase most often appears around pine tar soap, shampoo, grooming products, and traditional-style cosmetics. This does not mean crude wood tar is suitable for home cosmetic making. Finished products and raw materials are judged differently.
Cosmetic pine tar is about formulation and regulation. Craft pine tar is about wood, rope, boats, and timber. A product made for skin should be labelled, assessed, and used only as directed.
In short: Appears in some personal-care and cosmetic contexts. May be listed by botanical ingredient names. Finished products differ from crude tar. Health or skin claims require proper regulatory backing.
