Problems in White phenyl Manufacturing

A discussion started in 2002 but continuing through 2018


Q. I am a manufacturer of white phenyl but I am getting some problems. Some oils gets deposited on top. Slowly the color fades out. Can anyone please give some hint as what could be the reasons?

- Mysore, Karnataka, India




A. It's a normal problem in manufacturing it; it's not a matter of worry. Please mix the water and concentrate very slowly; for example, if you are mixing one liter concentrate with 10 liter water then take one liter concentrate and add a few water then mix the concentrate very slowly again add few water and mix it properly then slowly add a little water then again mix the concentrate. You will get thick white color concentrate and then add water again; this is the procedure.

A. The response to the following query from Rajeshwari, Mysore:

You can add some amount of gum acacia and stir well during manufacturing of this emulsion. The deposition of oil on the top will be emulsified into the aqueous phenyl.

A. Dear Sir

Reference Ms Rajeswari, Mysore, problem of oil separation.
Many manufacturers use various perfumery oils for this purpose; in most cases these oils are not emulsified properly to mix homogeneously into the solution.
As such, the oil separation.

Q. Dear sir ,
I made it but after adding perfume, I get smell of cutting oil.
What to add to avoid that smell.

A. Do add pine oil 1 liter maximum in 200 liters of phenyl; there won't be a smell of cutting oil surely.

i. White phenyl Compound:

It's a raw material for preparation of white phenyl. You can add 1 liter phenyl compound with 10/15 liters of water mixture.

thumbs up signAlrighty then ...   :-)

If the way to make "white phenyl" is to dilute "white phenyl compound" by 10 or 15 to 1, let the question be rephrased as "How does one make 'white phenyl compound' "?

A. Take 500 gram of castor oil, 500 grams of pine oil of 32% and mix both in a steel vessel, heat it with steam till till it gets very hot, take 10 grams of caustic and dissolve it in 100 ml water, pour the caustic solution in the mixture of castor/pine. heat it through steam until it turns dark brown and starts to become thick. Then let it cool down. Then add 200 grams of cutting oil and 100 grams of detol. The compound is ready.

Q. I am manufacturing it with out any mixer and packing in plastic bags (1 liter). After weeks storing became water-like or less white; please guide me how to overcome the problem.
Thank you.

A. 1.First you test your water on water p.H. meter
2.Your water should be 80-170 in pH -- It is Hardness test [ed. note: there is an error here because pH scale only goes from 0-14; perhaps Satya means ppm, i.e., mg/l?)
3.If your water is hard you use PGN in Pine oil
4.1 liter 40 ml PGN
5.PGN works for softening the water, and create Hardness white phenyl.
6.Lastly I recommend please follow the formula a professional way.

A. Hi Vishal.

I can't answer your questions in full, but PGN is probably "Propylene glycol methyl ether acetate".

Hi, Lalit. There have already been a good number of responses. Please try your best to cast your question in terms of what has already been said, so that the page doesn't just run in circles :-)

Sorry but this page is for public technical discussions; for a number of reasons we do not connect people commercially. Good luck.

A. It is indication of excess pine oil.
Take proper measured t.r.o 1 part and 3 part of pine oil. Shake it uniformly for 5 minutes, the mixture must be in proper ratio,
Wait for 3 days, you will get good result. Recently I heard there is one time introduced, if you have details, give full details

A. The Concentrate should be made with TRO not with cutting oil.The concentration of TRO and Pine/TOP should be clear.

Q. I am currently doing trials. I have tried with ready made concentrate in which we need to just add Pine Oil available in the market. But there are not up to the mark. So now I am trying to start full in house. If any one can guide, it will be helpful.

A. We are a manufacturer of TRO. While preparing white phenyl confirm purity of TRO: it should be 70% & its pH should be neutral. Take 3 parts pine & 1 part TRO till you get clear transparent brown colour liquid. Take 9 liters water charge 1 liter of this concentrated mix to get 10 liters white phenyl. There will not be any problem of oil separation and fading of colour.
