本数で示した。(1) Storage stability (bottle appearance) Evaluation method The bleaching compositions shown in Table 1 were polyethylene cylinder bottles shown in FIG.
l, bottom wall thickness: 0.6mm), sealed 600ml, stored at 50 ° C for 14 days, taken out and observed the swelling of the cylinder bottle with the naked eye. Fig. 1 (A) shows the bottle in a normal state. , And the bottom portion 2 is in a concave state inward. FIG. 2 (B) shows an inflated cylinder bottle 1.
This shows an example in which the bottom 2 bulges outward.
Here, the evaluation criteria for the swelling of the bottle are as follows. Each test was performed with 10 bottles, and indicated by the number of ○, Δ, and ×.
評価基準 ○:変化なし〔第1図(A)〕 △:ボトル底部がやや膨らみ、ボトルのすわりが悪くな
