Abstract

Description
泡の安定性を調べる試験は、脱イオン水および“硬“水源から得た水を用いて行った。この例での硬水源は、石灰鉱山から汲み上げられたもので、カルシウムとサルフェートが飽和している。この水の分析値を表2に示す。
第2の試験は、硬水試料に対して、この安定な石鹸(FA−403石鹸)と共にCA−330石鹸を使用して実施した。FA−403石鹸は、組成物の疎水性部として炭素数8のアルキル鎖長と炭素数10のアルキル鎖長の両方を有していて、炭素数8のアルキル鎖長が約40%、炭素数10のアルキル鎖長が約60%である。CA−330石鹸は、プラントで代表的に使用される他の石鹸と近似した固形分パーセントであるので、ここで使用した。
