Formulating

Milk Bath

Posted by Sheng on November 26, 2018 at 8:28 am

hello,

I am currently working on Liquid Milk Bath. It is a clear liquid product that turns into white when wet.

I have used several essential oils but still the “white” effect is not achievable.

below is my formula base

VCO qs 100

Rosehip Oil 5

Olive Oil 5

IPM 20

BHT 0.05

Jojoba Oil 3.0

Can you recommend emollients that can help achieve “whitening effect” on skin once wet.

Thanks.

Emollients won’t give you the “whitening” effect. The whitening effect is emulsification. You need an emulsifier to achieve it. Add a liquid emulsifier to your formula and a clear product will become white, once mixed with water.

@ngarayeva00 does KYMF-1 (INCI NAME: Acrylates Copolymer) provides emulsification? or do you have particular emulsifier in mind?

thanks.

Acrylates copolymer is a rheology modifier not an emulsifier. First guess -sorbitan oleate. It’s liquid and transparent.

Ok. how about if I use Polysorbate 20?

@ngarayeva001, I tried using Polysorbate 20 and Cetiol HE and was able to get “milky effect” when wet.

thanks so much for your insight.

BTMS-50 in water
thinned out with glucosides will give you the white milk effect.

@Gunther, is BTMS-50 clear liquid?

I have not tried mixing polusorbates with oil but something tells me it’s a bad idea. Polysorbates are high HLB. Experiment and you will figure it out. Try surfactants too (glucosides, as mentioned above)

@ngarayeva001, ok noted. I’ll try to experiment with decyl glucosides.
