from the Jack Black website :
Authentic and Original
Jack Black is a line of high performance shaving, skin care, sun protection and grooming products designed exclusively for men. The unique combination of authentic ingredients and original technology offer men real solutions that go beyond soap and water. Nothing complicated, nothing cosmetic. Just superior products designed with guys in mind.
Each Jack Black product contains only the finest natural ingredients - highly efficacious, benefit oriented extracts and botanicals - discovered during our search for the finest ingredients that could be used in the "best of the best" men's products. The authentically masculine ingredients we uncovered during our search have a rich history. They have appeared in the most interesting places - from the ration packs containing after-shave and talc used by soldiers in World War I, to the heritage of the barber shop, a place where our dad and granddad experienced original shave formulas. These tried and true ingredients - like eucalyptus, sage, lavender and rosemary - are fused with advanced technology and the latest science to create outstanding products that offer true benefits to the skin
Jack Black products are designed with your lifestyle in mind - every product is multi-functional and easy to use, so minimal time and effort is required to get great looking skin. All Jack Black products are lightweight - never heavy or greasy - and are free of artificial colorants and contain minimal fragrance.
All Jack Black products are subjected to extensive quality assurance, safety and efficacy testing. We use no animal-derived ingredients, nor do we perform (or have outside parties perform on our behalf) any product testing on animals. All our formulations are thoroughly tested by real men and by an independent dermatologist before being marketed.
You'll find Jack Black in the locker room of some of America's best sports teams, plus in the hands of many professional athletes and thousands of regular guys who want to look their best.
