PURPOSE:To obtain the titled composition in the form of gelatinized layers with hardly any phase separation and deterioration of quantity of latent heat by repeating melting and coagulation, by blending sodium sulfate decahydrate (eutectic substance) with an isostearate and hydrous and amorphous silicon dioxide. CONSTITUTION:The aimed thermal energy storing agent composition for latent heat obtained by blending (A) 100pts.wt. principal component consisting of sodium sulfate decahydrate or an eutectic substance thereof with (B) particularly preferably 0.5-2pts.wt. alkali metal salt of isostearic acid and (C) particularly preferably 7-15pts.wt. hydrous and amorphous silicon dioxide produced by a wet process. |
