Reduced burning and stinging associated with topical application of lactic acid 10% with strontium versus ammonium lactate 12%.
Burning and/or stinging is one of the most common concerns expressed by patients using topical therapies for treatment of dermatologic disorders. Topical lactic acid preparations often are used to treat dry scaly skin. In this study, we compared the level of burning/stinging reported by participants with application of lactic acid cream 10% containing strontium versus ammonium lactate lotion 12% and cetearyl alcohol lotion. The mean rating of burning/stinging reported for lactic acid cream 10% with strontium and cetearyl alcohol lotion was lower than ammonium lactate lotion 12% (P<.0001). Based on the study results, lactic acid cream 10% with strontium causes less burning/stinging than ammonium lactate lotion 12%.
Abstract The use of common structural alloys with pre-formed aluminide diffusion surface coatings is one approach proposed to inhibit corrosion by lithium. This study involved exposing commercially coated and uncoated ferritic and austenitic alloys to pure liquid lithium, in a 400°C recirculation loop, to determine the stability of the treated materials. Detailed metallographic analysis provided results for an initial screening of the test materials for future applications and testing.
