Plus,every ingredient of LIP BUTTER is an ingredient of MENS NULL Face Wash or an ingredient of Eye Shadow (Shell). All this entails that being an ingredient of LIP BUTTER is sufficient for not being an ingredient of Flex Foundation."
Is the argument, given the explicitly stated premises, deductively valid or invalid?
