Expiry date & Shelf Life
Hi,
I have been making organic natural skincare lotion with a shelf life of 6 months using natural preservative. I tried to sell to retailers but they required my product to have at least 2 years expiry date/shelf life.
I found that other natural skincare brand have a 3 years expiration date if unopened (and 1 year shelf life after opened).
May i know if anyone know how to make to seal my product with a very long expiration date ? Do i just need to use hot-air sealing machine to seal my product? Or do i need to add some nitrogen in it? or any other methods?
Please kindly help
Thank you in advance

Thanks all for your reply!
Apologies - let me clarify my question. I would like to know why the expiry date can be extended when the product is unopened. Is it because they use any technique to seal the product (add nitrogen and no oxygen inside the product)?
And here is my product's recipe. I use natural ingredients. Please kindly help
6g Olivem 1000 emulsifier (Cetearyl Olivate, Sorbitan Olivate)
3g cetyl alcohol
10g avocado oil
10g macadamia oil
66g distilled water
2.5g glycerine
0.5g Vitamin E Oil
0.5g ylang ylang essential oil
0.5g frankincense essential oil
1g Preservative Eco (Benzyl Alcohol (and) Salicylic Acid (and) Glycerin (and) Sorbic Acid
Olivem 1000 should be an expensive emulsifier, resulting in an expensive end product. It is a must to have much better shelf life
remember this ain't a pharmaceutical or food product that is readily consumed after opening
rather it can be left opened for months before all it's used up by the customer.
So proper preservatives are unavoidable.
P.S. I believe there's either a limit on how much salicylic acid you can use skin applications, there must be warning on the label.
Thank you very much
may i know if i can just do the freeze-thaw testing but not the oven testing?
Or i need to do both? Thanks again!
In addition, does anyone have an idea on the "sealing technique"? If the product is sealed (using hot-air sealing machine). Does that mean the shelf life will be extended?
Thank you again
