Gritty deodorant

I've made a deodorant/antiperspirant with a few actives a few days ago.
Point is, something seems to have precipitated as the cream feels like there is a bit of very fine sand in it.

A )
Distilled+deionized water ad 100
3.0%    Glycerin
0.4%    Allantoin
30.0%  Locron L (50% aluminum chlorohydrate in water)

B )
6.0%    GMS + Ceteareth-20
3.0%    Cetearyl Alcohol
4.0%    Triethyl Citrate
2.0%    Dimethicon 100 cSt.
3.0%    Isopropyl Myristate

B1 )
1.5%    Sepimax Zen

C )
0.5%    Cyclopentasiloxane
2.0%    Vari Stan PE (Propanediol, Garcinia Mangostana Peel Extract)
1.0%    Phenoxyethanol (90%), Ethylhexylglycerin (10%)

Phase A: 70C
Phase B + B1: 70C
<40C Phase C one by one.

Phases start separating immediately, but after vigorous high shear mixing it emulsifies into a very viscous emulsion, too thick for my pH meter to get a stable reading.

I don't know if the 'sand' is aluminum or allantoin.

Any ideas or suggestions?

    Btw: the cool down was rather quick (put in fridge, I was in a hurry) :grimace:

    You think you can try to dissolve that precipitate in water and see if it completely disperses or not. Should give you an idea what it could be.
