A polyolefin-containing material including an internal additive, where the internal additive is a triglyceride according to the structure (T): <?in-line-formulae description="In-line Formulae" end="lead"?>CH<SUB>2</SUB>(OR<SUP>1</SUP>)-CH(OR<SUP>2</SUP>)-CH<SUB>2</SUB>(OR<SUP>3</SUP>) (T) <?in-line-formulae description="In-line Formulae" end="tail"?> where R<SUP>1</SUP>, R<SUP>2 </SUP>and R<SUP>3 </SUP>are, independently of one another, saturated, mono- or poly-olefinically unsaturated acyl groups containing 8 to 24 carbon atoms, the chain lengths of the acyl groups are the same or different, and the polyolefin-containing material exhibits improved softness is provided. A process for the softening finishing of articles including polyolefins is also provided and includes adding a triglyceride to polymer granules including a polyolefin present in an amount of from about 0.1% to about 40% by weight, based on the weight of the granules, and subjecting to further processing to form a fiber or film.
