This figure shows SEM image of fabric softener liquid specimen at the stage temperature -140°C (Cryo transfer). The specimen was pre-processed using rapid freezing and freeze fracturing methods. This SEM images revealed that some 0.5 µm-diameter microscopic particles were densely packed in an approx. 8 µm-diameter particle. This multi capsule structure helps effective adherence of softener to fabric and softening and aroma effects in long stretches. This picture resembles dahlia petals with balmy fragrance.
