To provide a brittle material processing fluid composition which has excellent lubricity, antifoaming properties, and waste liquid treatment properties.SOLUTION: The present invention relates to a brittle material processing fluid composition which comprises (A) water and (B) an additive mixture. The component (B) comprises: (B-1) a nonionic surfactant which is an alkylene oxide adduct of an alcohol having 10 to 24 carbon atoms and has a HLB value of 4 or more and 11 or less; and (B-2) a copolymer of ethylene oxide and an alkylene oxide other than ethylene oxide. The content of component (B-1) is 0.9% by mass or more and 88.0% by mass or less based on the total amount of component (B) of 100% by mass. The content of component (B-2) is 0.9% by mass or more and 96.0% by mass or less based on the total amount of component (B) of 100% by mass. The total content of the component (B-1) and (B-2) is 83.0% by mass or more based on the total amount of component (B) of 100% by mass.SELECTED DRAWING: None 【課題】潤滑性、消泡性、及び廃液処理性に優れる脆性材料加工液組成物を提供する。【解決手段】（Ａ）水、及び（Ｂ）添加剤混合物を含み、成分（Ｂ）が、（Ｂ−１）炭素数１０以上２４以下のアルコールのアルキレンオキサイド付加物であって、ＨＬＢ値が４以上１１以下である非イオン界面活性剤、及び、（Ｂ−２）エチレンオキサイドとエチレンオキサイド以外のアルキレンオキサイドとの共重合体を含み、成分（Ｂ−１）の含有量が、成分（Ｂ）の全量１００質量％基準で０．９質量％以上８８．０質量％以下であり、成分（Ｂ−２）の含有量が、成分（Ｂ）の全量１００質量％基準で０．９質量％以上９６．０質量％以下であり、成分（Ｂ−１）及び（Ｂ−２）の合計含有量が、成分（Ｂ）の全量１００質量％基準で８３．０質量％以上である、脆性材料加工液組成物に関する。【選択図】なし
