NEW! Safe, mild and gentle SURFACTANTS for DIY facial wash, body wash & shampoo:
Preservatives are chemicals that kill bacteria, fungi and molds. They are commonly present in ANY product that contains water. For this reason, oil-based skin care products and anhydrous (water free) skin care products, do not need preservatives.
However, creams, lotions and any other product where water is present, require adding a preservative.
If you do NOT use a preservative, or if you decide to believe the hype and try out a "natural" preservative (such as grapefruit seed extracts), then you are putting yourself, and your skin, at RISK.
The only way you can avoid using preservatives is if you make your products FRESH every week, and store them in the refrigerator. This is what we, at BulkActives, do.
We have now started carrying two preservative systems. None are formaldehyde releasing, but they do contain other chemicals that have been getting an (unjustified) bad name (phenoxyethanol and the paraben family).
Let me repeat, if you make your products FRESH every week, and store them in the refrigerator, then, and ONLY then, can you avoid using preservatives.
Shelf life of products WITH preservatives
with preservative = one month
without preservative = one week and must be stored in a fridge.
The reason why we suggest 1 month for products with a preservatives is because:
ALL preservative manufacturers recommend that proper stress tests and plate counts are done under various temperatures and storage conditions, in order to calculate the correct amount of preservative used in a product in relation to the ingredients used.
This can take as long as 2 years.
Note that if you are planning on selling your products (on ebay etc.) then it is essential (to legally protect YOU) that this process is followed, preferably by a qualified person in a registered lab.
However, for DIY use, making a product (with preservative) fresh every month is perfectly safe.

Chelating Agents / Chelators
"Chelators attract metal ions to prevent microorganism growth or adverse reactions with active or inactive ingredients in a formulation. Use of chelators is especially important when metal-sensitive ingredients are used ( such as L-ascorbic acid, green tea extract etc.) It is a good idea to include a chelator in any formulation for which stability of an active is desired."

Butylated hydroxytoluene (BHT)
Butylated hydroxytoluene is a potent synthetic antioxidant. It is useful to add to skin care products that are expected to survive longer than a few weeks. BHT is NOT a preservative.
Just like food, skin products decompose over time. The reason for this is oxidation, a process in which harmful molecules called free radicals cause damage to cells. It's the same process that's responsible for the the eventual brown color on a peeled apple.
A skin product can undergo oxidative stress, too, rendering it ineffective. To counteract this issue, cosmetics companies use BHT in skin products. BHT has antioxidative properties, and it works to neutralize the oxidation process by taking on the stress caused by free radicals.
There is a lot of controversy over its use in food products, however, the amount of BHT used in cosmetic products is typically 0.01-0.1%, and does not pose a cancer risk to skin, nor does it penetrate skin far enough to be absorbed into the bloodstream (Source: 2008 CIR Compendium, Cosmetic Ingredient Review, 2008, pages 43-44).
