摘要:
It is to provide a composition derived from lactic acid bacteria having an anti-allergic effect (an effect of suppressing allergic symptoms such as hay fever) synergistically, and a food product, pet food, etc. containing the composition. It is to prepare a composition having an anti-allergic action, containing Lactobacillus crispatus KT-11 strain, KT-23 strain, or KT-25 strain bacterial cells and viable bacteria, dead bacteria, or a processed product of bacterial cells of other lactic acid bacteria belonging to the genus Lactobacillus, genus Bifidobacterium, genus Leuconostoc, genus Enterococcus, genus Pediococcus, etc. at a biomass-converted ratio of 99:1 to 50:50, preferably 99:1 to 75:25.

摘要:
The subject of the disclosure concerns microcapsules including a core containing one or more alkali metal borates, optionally hydrated, dispersed in one or more lubricating base oils of mineral, synthetic or natural origin, and a polymer shell. Another subject of the disclosure is a lubricating oil including microcapsules. A further subject of the disclosure is the use of microcapsules according to the disclosure as anti-wear and/or extreme pressure additive for lubricant compositions. A further subject of the disclosure is a method for preparing microcapsules by interface polymerization.
摘要:
The present invention provides a grease composition for constant velocity joints containing a lubricating base oil, at least one thickener selected from urea-based thickeners, urethane-based thickeners and urea/urethane-based thickeners, an organomolybdenum, a zinc dithiophosphate, a polysulfide, and a triglyceride, wherein the content of the organomolybdenum is 1000-5000 ppm by mass in terms of molybdenum element based on the total amount of the grease composition. According to the grease composition, it is possible to exert sufficient characteristics even in the case of reducing the amount of the additive such as molybdenum disulfide.
