environmental products

I'm living in Jinotega and will be making a trip to Managua next week in search of some items I can't find here.

Does anyone know where in Managua I can purchase Biolandia products, or other similar products that are environmental and health friendly?

I am looking for both personal care products (shampoo, soap etc.) as well as cleaning products for the house (laundry soap, dishsoap etc.).

If you can include the name of the store where I can buy them and any directions (to give to the taxi driver) that would be great.

Thanks!
