Patent ID: 7741266

Claim:
A process for preparing a scented cellulosic with optimal fragrance intensity, comprising the steps of: (a) determining an amount of net plasticizer to be added to a pre-melt cellulosic composition; (b) selecting a high preliminary fragrance:plasticizer weight ratio of the net plasticizer, wherein the high preliminary fragrance:plasticizer weight ratio is 2 or higher; (c) adding the net plasticizer with the high preliminary fragrance:plasticizer ratio; (d) determining the fragrance:plasticizer weight ratio of net plasticizer that achieves maximum fragrance intensity in the processed scented cellulosic by decreasing the fragrance:plasticizer ratio of the net plasticizer in iterative trials, while the amount of the net plasticizer remains constant over the iterative trials; (e) selecting a final fragrance:plasticizer ratio based on the desired fragrance intensity of the scented cellulosic, wherein the final fragrance:plasticizer ratio is less than or equal to the fragrance:plasticizer ratio in step (d) that achieves the maximum fragrance intensity; and (f) preparing the pre-melt cellulosic composition having the final fragrance:plasticizer ratio.
