Methyl-Sulfonyl-Methane (MSM) is an organic sulfur compound which is a metabolite of dimethyl-sulfoxide (D.M.S.O.). It is a white, odorless, slightly bitter tasting, crystalline substance, which contains 34 percent elemental sulfur. It is easily soluble in water. Its chemical formula is (CH3)2SO2.
INCI: Methylsulfonylmethane Purity: 99% Physical Form: Clear Crystals Melting Point: N/A Applications: Topical Usage Rate: Up to 8% (start at a .5% or lower) Solubility: Water Organic: Yes
It has been suggested by Lovelock and his associate's (1) that M.S.M. and its related compounds D.M.S.O. and D.M.S. (dimethyl sulfide) provide 85 percent of the sulfur found in all living organisms. The cycle of these naturally occurring sulfur compounds begins in the ocean where microscopic plankton release sulfur compounds called dimethyl sulfonium salts. These salts are transformed in the ocean into the very volatile compound D.M.S. which escapes from the water as a gas which rises into the upper atmosphere. Exposed to ozone and high energy ultraviolet light the D.M.S. is converted to D.M.S.O. and M.S.M. Both the D.M.S.O. and M.S.M. are very soluble in water and they return to the surface of the earth in rainwater. Plants then take up the two compounds into their root systems concentrating them up to one hundred fold. M.S.M. (sulfur) is incorporated into the plant structure. Through the process of plant metabolism the M.S.M., along with the other sulfur compounds it has spawned, are ultimately mineralized and transported back to the ocean and the sulfur cycle begins again.
Shelf Life and Storage Information for Products and Ingredients
Finished Products generally don't need to be refrigerated as they are preserved, but you can refrigerate them to extend their shelf life. The shelf life for most products is 9-12 months. Vitamin C Serum(s) and VitaResurface products should always be refrigerated to extend their shelf life.
Sample Sizes do have a shorter shelf life (generally 3-6 months) and items in jars can dry up quicker than this if the lid is not tightened well enough (except our Vitamin C Serums - use within 90 days).
Please keep your products out of high humidity, heat, and direct light, and keep them in a dark cabinet when possible.
Exfoliating Acid products have a shelf life of 9-12 months. The only things we don't suggest refrigerating are the Mandelic Acid Serums or the Salicylic Acid Serums as those can crystallize in the refrigerator. If this happens you can set the product into a hot water bath to see if the crystals will dissolve.
Additional Items Requiring Refrigeration and/or Kept in the Dark
Hydrosols - remove 1 ounce of hydrosol and add it into a separate, sterilized spray bottle and spritzer. Keep the larger bottle in the refrigerator. Carrier Oils - generally you can refrigerate all carrier oils although some of the very rich oils will solidify. This is fine. All you have to do is take it out, warm it up at room temperature and it should liquefy. If not, setting the bottle in a hot water bath and occasionally shaking the bottle will hopefully turn into a liquid. ^There are some oils that have a super long shelf life like Coconut Cream and Jojoba Oil. Refrigeration is not necessary, but it surely won't hurt. Essential Oils - essential oils are best stored in a cool dark place. Co2 Extracts - these should always be refrigerated. Butters - we suggest refrigerating our "skincare' butters. You can take out what you need and keep the rest in the fridge. Clays - keep in a dry, dark place. Shelf life is at least 2 years. Herbs - all herbs (whole or ground) should be kept in a dark, cool and dry location. Herbal (liquid) Extracts - these are created using alcohol. The alcohol pulls the constituents from each herb. Root, Trunk, Leaves, and Flowers. Extracts have a shelf life of 3-5 years. They can be kept in the refrigerator (or a dark DRY place) Other Various Raw Ingredients - i.e. Sodium PCA, Honeyquat, Oat Beta Glucan, etc. will all have a different shelf life.
