Deodorants

"Zinc Ricinoleate present binds up odor molecules."
Zinc - "Dr. Scholl's Deodorant Foot Powder with Baking Soda & Zinc Oxide - With Zinoxol, advanced odor fighting ingredient. http://www.medshopexpress.com/030323.html

Some countries (pharmacies) carry a zinc power, which can be used alone or with baking soda as a deodorant.
 

Cautions

Commercial metals such as zinc & especially aluminum are of concern.
Zinc Oxide - http://www.lookchem.com/zinc-oxide/
Zinc supplementation - http://www.nutritional-supplements-health-guide.com/benefits-of-zinc-supplements.html - "It is recommended to use 50mg per day during pregnancy which should be taken separately from iron. Up to 200mg of zinc per day is quite safe but if a zinc supplement is to be used for long periods a (reduced) dosage of 20mg per day is recommended. Most multivitamins contain the recommended daily allowance of zinc.  Zinc supplement over long term usage can interfere with the absorption & utilization of other nutrients, such as iron and copper. Excess zinc supplement misuse can cause nausea, vomiting, and diarrhea. Zinc supplement misuse can also cause a lowering of the level of HDL or good cholesterol. It can also lead to poor immune system function."  (Zinc is typically used by men rather than women except when treating viruses such as colds.)
 

Disorders
 
Trimethylaminuria "is a metabolic disorder in which an individual is not able to break down trimethylamine into smaller compounds. Trimethylamine is the compound that gives fish their fishy odor...
People with trimethylaminuria lack the enzyme flavin-containing monooxygenase 3 (FMO3), which is produced by the liver and is part of a family of similar enzymes responsible for breaking down compounds that contain nitrogen, sulfur, or phosphorous.[3] This enzyme is produced by the FMO3 gene.
Not all of the functions of the FMO3 enzyme are known, so physicians don't know what other symptoms besides odor may be associated with trimethylaminuria.[1][2]"  (The disease can be inherited as well as tested for. 
There are many many ways to reduce the offensive fish odors:)
"(1) Avoiding foods containing trimethylamine & its precursors (choline & trimethylamine-oxide).
Trimethylamine is present in high levels in milk obtained from wheat-fed cows. Choline is present in high amounts in: eggs; liver; kidney; peas; beans; peanuts; soy products; brassicas (brussel sprouts, broccoli, cabbage & cauliflower); & lecithin & lecithin-containing fish oil supplements.  Trimethylamine N-oxide is present in seafood (fish, cephalopods, crustaceans). Freshwater fish have lower levels of trimethylamine N-oxide.
(2) Taking low doses of antibiotics (or preferably supplements such as medicinal mushrooms) to reduce the amount of bacteria in the gut. This suppresses the production of trimethylamine.
(3) Taking (preferably natural) laxatives can decrease intestinal transit time and reduce the amount of trimethylamine produced in the gut.
(4) Taking supplements to decrease the concentration of free trimethylamine in the urine.
(5) Activated charcoal taken at a dose of 750mg twice daily for ten days.
(6) Copper chlorophyllin taken at a dose of 60mg three times a day after meals for three weeks.
(7) Using soaps with a moderate pH, between 5.5-6.5.
Trimethylamine is a strong base (pH 9.8), thus soaps with pH closer to that of normal skin help retain the secreted trimethylamine in a less volatile form that can be removed by washing.
(8) Taking riboflavin (vitamin B2) supplements to enhance any residual FMO3 enzyme activity.
Recommended intake is 30-40mg taken 3-5 times per day with food.
(9) Avoiding factors that promote sweating, such as exercise, stress & emotional upsets."
