Powder stability

Neither hydrochloric nor nitric acid initiates a self-sustained reaction in powder stabilized with sodium carbonate or magnesium oxide. 

J. Taylor has described a method of igniting Hydrox powder stabilized with 2% sodium carbonate it consists of adding 0.2 cm3 of 50% solution of chromic acid. 

Sunlight is a factor which hastens the decomposition of smokeless powder. Experiments carried out by D. Berthelot and Gaudechon [60] showed that powders containing various types of stabilizers behave in different ways towards light. E.g. powder stabilized with amyl alcohol proved to be more resistant to sunlight than that containing diphenylamine. The latter darkens very rapidly under the influence of light, which no doubt accelerates the decomposition of diphenylamine. 

The crystallization principles previously discussed are applied in processing dairy products, such as sweetened condensed milk, instant milk powder, stabilized whey powders, lactose, and ice cream.

Author of many researches on aromatic nitro compounds, nitrocellulose, smokeless powder, stabilizers and stability, chlorate explosives, etc.—published for the most part in the Memorial des poudres and in the Bulletin de la societe chimique de France.

The composition described includes sugar, cocoa powder, stabilizer, Jerusalem artichoke powder, and milk base. The pudding has improved taste, higher biological value, and curative and prophylactic properties.
