Can a large log buffer cause data loss?

hI am not so sure about how the log_buffer parameter works. Does the buffer work as a cache (wait to write until log buffer is full or some other criteria) or is it used to avoid wait when the LGWR process is busy writing to log files.

if log buffers is used as a cache, couldn't this cause data loss if the Oracle instance crash? Then all buffers in the cache would be lost. I hope and don't think it is this way, but I want to be sure.
