For example, it is possible to simultaneously satisfy the above characteristics as well as odorlessness, which was previously impossible to achieve in polyolefin resin molded products such as films and containers, and it is suitable for polyolefin molded products in the fields of cosmetics and food products. This made it possible for the first time to develop an even wider field of use.

The reason why the composition of the present invention exhibits the above-mentioned excellent effects is not necessarily clear, but it is possible that benzaldehyde, which is the raw material for producing dibenzylidene sorbitol of JP-A No. 57-21440, and the raw material for producing the dibenzylidene sorbitol derivative of the present invention. Benzaldehyde derivatives such as certain ρ-substituted benzaldehydes have odors, and even after purification, a slight amount of benzaldehyde derivatives inevitably remain in dibenzylidene sorbitol (derivatives), which tends to cause off-odor in polyolefin resin molded products. In the composition of the present invention, (1) -i specific dibenzylidene sorbitol of formula (I) By simultaneously satisfying the requirements (1) and (2) of using solid particles of the derivative and (2) coating the particles with a specific higher fatty acid of general formula (II), raw benzaldehydes or decomposition products can be treated. The effects of the polyolefin resin molded article are that the off-odor that is presumed to be caused by the benzaldehydes is significantly reduced, and the above-mentioned physical properties such as transparency are also excellent.
