People can easily make their own exfoliating bath scrub all they need is a jar, olive oil, sugar, Vitamin E capsules and their favorite essential oil or fragranced oil.  If they buy in bulk then they make it really cheap.  What Burt's Bees needs to do is provide that extra benefit to it, the anti-aging additive and clinical data to prove it might do it.

unless it has some unique form of skin/sun protection I don't think it can be patented. There are a lot of books out there for do it yourself natural skin care that list beeswax, soils and such to make balms and such. 

I am not sure of the numbers but it looks like it still is a growing category, based on this recent article from cosmetics design. Back in 2007 the US version of this site stated they thought it was going to go stagnant due to the amount of products on the market. I guess they were wrong.

For liter it would have to work and shown that it works before I would pay extra money for.  I bought the crystals when it came out way back when and that was a complete waste of my money.

Neem seed oil is very bitter with a garlic/sulfur smell; it contains vitamin E and other essential amino acids.

They may not kill the pest instantaneously but incapacitate it in several ways. Neem very subtly employs effects such as repellence, feeding and ovipositional deterrence, growth inhibition, mating disruption, chemo-sterilization, etc..

Extracts from neem have shown incredible success with not only battling fungus problems but also many forms of root rot. Neem biodegrades in a matter of weeks when exposed to the sunlight. Pure Neem oil will retain its potency much longer if stored in a cool place away from strong light. Here are some tips on using Neem oil: (1) Don’t mix any more than you need.

A weaker solution may be used for maintenance. INCI: Azadirachta indica.
