  Gritty deodorant

  Posted by Doreen on June 20, 2018 at 3:09 pm

  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
  A+B
  <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.
