@Chemist77 can you refer me to the link of that particular discussion ? thanks

@ozgirl
“You will probably have better luck creating a stable product using a combination of emulsifiers/surfactants (a blend of low HLB and High HLB) or even adding some ionic sufactants.
can you recommend what kind of ionic surfactants that i can use?

For the record Nonylphenol ethoxylate-9 is not a natural product. “
i am aware of this. but I have searched and read some in the forum that np-9 should be fine. maybe do you have anyother surfactant that will give me a stable emulsion and its natural ? 

@Chemist77 it seems you mentioned alot chemicals, I am trying to make as less chemicals as possible. thank you, i will definitely consider those.

@DAS is it that hard to get a stable emulsion ? 

[ryanou]

@DAS lets say i get a stable milky emulsion in a 2L jar. inside i have 1% of oil and 0.25% surfactant.. if i want to make a 90L solution. can i multiply the amount of oil and surfactant by 45 and it still give me the same end result?

[ryanou]

@DAS the styrene, isnt it oil based ? will it easily dissolved in water? 

i tried Titanium dioxide before with the help of CMC (not stable yet). i can see the TiO2 settled at the bottom.. =.=

[ryanou]

@DAS well, i wanted it to be natural white look on the product. i have tried TItanium dioxide powder, and it wont mix or dispersed completely in water. over time it will settle down at the bottom of a jar. 

I havent tried styrene/butadiene as i try to make a product with least chemicals involved . so i want to look as natural white as possible, that is why i am always having problem with the emulsion. is there any natural way to make the product white ? 

[ryanou]

@DAS hi das. i found that adding too much of the surfactant solved the creaming problem, but another problem occur, it seems that the mixture started to break down, it doesnt suspend and it doesnt float. its hard for me to describe here. anyway, can you give me hint . let say i want to make a 4L mixture and it contains 1.5% oil, 1% surfactant, 2.5% Thickening Agent (CMC), and the rest is water.

I started by mixing the Oil and Surfactant and do a gentle stir with a wooden spatula, and then add slowly the thickening agent so that i get a nice thick milky lotion like solution, and then i poured in the water slowly. 

at first it was all nice, adding so much water the solution became watery and not as milky white as i want. please do give me some hint on how to have a milky white solution :'( been wasting alot of expensive oils and surfactant and yet to get the result that i want.

Below always happened, been trying to make a perfect one but failed i think about 50 samples with different composition.

@Bobzchemist hi bob… do you have the procedure of making the emulsion ? 

lets say I want to have a 4 litre mixture. so in it normally i would prepare about 1.5% Oil , 1% Surfactant, about 2.5% thickening solution (CMC) and the rest would be water. how do i start the procedure by doing the gentle mixing procedure? i want it white milky at the end .

[ryanou]

@DAS thanks for the kind reply. I havent tried the doubled amount of surfactant, but i found 4% of total formula is sufficient to make it white and quite viscous. 

do you think by adding more surfactant it will cause even whiter and more viscous ? i am actually want to make a concentrate formula. 

[ryanou]

@Lainee hi.. thanks for the reply .. I will do some experiment! but i think mix them manually will create a more stable emulsion compare to a high shear mixing using a blender.. hm….i wonder why

[ryanou]

@Bobzchemist yes. if you look at my composition, is 4% enough ?

[ryanou]

Thanks for the Reply.

@fkay, i dint do oil heating as to save time in making the product, do i need to heat the oil ? 

@DAS , thanks for your input. so if in this particular case, i want to make a Litre product, i will have to have 100mL of surfactant and same amount of oil which is 35mL Citron Oil and 25mL of Pine ? isnt it too much of a surfactant to use ? 

I have tried using a wooden spoon during the blending, and i found it seperates even faster as i supposed the whole thing doesnt blend properly.

I am trying to make a floor cleaning formula which has a disinfectant affect and also a bug repellent property in it.
