Deodorant is too runny in summer
Hey to all
I was about to send my deodorant to tests so i ian get license to sell. It was August. Very hot where i live - israel. 38 degree ish.
Luckily i recognise that the deodorant is not acting the same. Its separate, as in liquid. Very runny. I noticed its only for a month or so… And than back to regular smoothly texture.
The ratios are : shea butter 27.16
Grapeseed oil 27.16
Magnesium hydroxide 16.97
Tapioca starch 13.58
Bentonite clay 13.07
Vitamin e 0.59
Presevetive 0.59
E oils 0.88.
Than i started making experiments to find a formula that is not so different between summer and winter. I found one. Cetyl alcohol and candelila wax in the right ratios it is great in high and low temperatures. I lowered the shea butter to 3.26%
Candelila wax was 1.3% and cetyl alcohol was 9.8%. except for the frosting kind of around the cream, it didn’t work the same /: i tried with and without clay. Both dont really work. The big thing that i change is the quantity of shea butter.
How can i make my deodorant stable in summer and winter and work ? Too many tries, its better to ask the specialist
Thanks in advance

You could probably have the melting profile of the mixture investigated. You’ll know where the solidifying range lies and whether that’s anywhere close to 38°C.
I’d assume it is as, although you’re using tapioca starch, MgOH and bentonite as solidifying agents, there’s still a reasonable amount of lower viscosity (grapeseed) oil and reasonably ‘meltable’ shea butter.
Perhaps trying something like microcrystalline wax or beeswax to firm it up a little and bring the melting ‘shelf’ a little higher? If trying with beeswax, maybe add a little castor oil to aid slip? -
@Batya The frosting you see is from the butter. Butters should be tempered before manufacture. Try placing it at around 60C for 10-15 min befor the process. Also, you mentioned you’re using Candelilla wax and Cetyl alcohol, which are the waxes that will provide hardness to the product. Try to change the ratio between them, favoring Candelilla wax which will give you a more firm product.
