A triangle outline, the GINETEX base symbol for bleaching instructions on a garment care label.
Also known as: Bleach triangle symbol
One of five base categories in the GINETEX/ISO 3758 textile care labelling system: an empty triangle permits any bleach, two diagonal lines inside restrict it to non-chlorine (oxygen) bleach only, and a crossed-out triangle prohibits bleaching entirely.
An empty triangle means bleaching with any agent is permitted; two diagonal lines inside restrict it to non-chlorine (oxygen) bleach only; a crossed-out triangle prohibits bleaching altogether.

Non-chlorine bleach only
A triangle with two diagonal lines inside, restricting bleaching to non-chlorine (oxygen) bleach only.
Do not bleach
A triangle crossed through with an X, prohibiting any bleaching agent.
An empty, equilateral triangle outline. In the GINETEX care-labelling system the triangle always means bleaching, whatever is drawn inside or across it — diagonal lines inside restrict which bleach may be used, and a cross through the triangle forbids bleaching altogether.
Both belong to the Laundry care symbols system.
