@Perry 10 years down the line the concept has been twisted so much that co wash has become an ‘eye wash’ 

[Chemist77]

No I am not aware of the composition, as far as I know the label says Vanilla. Beyond that all I know is that I read somewhere that we have explored the Mars but no settlement yet for this Vanilla issue (

[Chemist77]

Since I am no expert I would start with discoloration of vanilla in our white products, how can it be minimized or prevented????
(You said something for all to understand).So here you are

[Chemist77]

First would be the explanation of polarities of fragrance components in general and their effect on various type of solvents like ethanol, water, emulsion, surfactant and so on. As laymen its very struggling for us to choose a fragrance for our formulas and then end up going back to the board just because the fragrance is destabilizing the emulsion/shampoo/or any other product.

[Chemist77]

@IrinaTudor Sure thing but since your are the leader here guess you start the thread or me?????

[Chemist77]

@IrinaTudor Actually me nd @Belassi were having a discussion on polarities and solubilization, my take was that I am able to dissolve majority of fragrances in my absolute ethanol (denat.) and what we missed is that even the components of a fragrance have varying polarity and which gives rise to this phenomenon of varying solubility. And of course I am guessing there is H-bonding involved too between ethanol and fragrance components (which are just so many and so varied), am I being naive in my understanding here??????
Your input would be of great help.

Cheers

This forum appreciates people who complete the cycle by giving the feedback.

Thanks a ton @Belassi, really appreciate your openness about sharing information. Now fingers crossed to see people having dandruff ) and employing this formula

[Chemist77]

Just as you use other mineral clays in masks and similar products (e.g. china clay) here Fullers earth has been used, secondly the LOI seems to be completely misguiding after Fragrance. Normal cationic emulsion with cetostearyl alcohol as thickener and Glyceryl stearate & Peg-100 Stearate as emulsion stabilizer. Maybe lecithin too is giving some form of backup to stabilization of the emulsion. I am guessing (and plz correct me if I am wrong) the mineral clay too is contributing to the thickening and stabilization of emulsion here.

@Rahma  Mind you the coconut ale and blueberries must be NATURAL.  )

[Chemist77]

Thanks a lot, seems like a 3-in1 here. Cleaning/anti-dandruff/conditioning

[Chemist77]

@Belassi Plz do so, its always a gain to look at a formula. 

[Chemist77]

I would add dip slides (from S&M) as well for in house micro testing.

[Chemist77]

Guess @IrinaTudor could explain this in a much better way for us. 

[Chemist77]

Well if you check the compatibility chart then you would see that ethanol and cyclomethicone are miscible, does that lead somewhere?????

[Chemist77]

@Belassi Good luck and plz let us know the results. 

[Chemist77]

Whether two chemicals can dissolve together depends on the similarity of the chemical structure, and/or on the interaction between them (eg, whether the hydrogen bond can be formed between two chemicals).

http://en.wikipedia.org/wiki/Hildebrand_solubility_parameter
If the difference in the solubility parameters of these two chemicals is less than 0.5 cal1/2 cm-3/2, then it is very likely to dissolve each other.

I was able to pull the above article from net when you woke me up about the polarity difference hope it can help a bit to understand the above phenomenon better. 

[Chemist77]

@Belassi It’s a 2 way thing, your practical experience vindicated what I had read in theory. And thank you for sharing everything here, we are blessed to have people like you and other senior mentors whose experiences mean a lot for less learned like us.

Cheers

@Belassi I suppose with sufficient ethanol and water balance the fragrance can have good solubilization in body splashes. As a matter of fact problem occurs when there is solubilizer and which tend to solidify at lower temperatures. PEG-40 HCO is a classic example, in summers its pretty liquid but in winter at times we have to warm it to melt it.

But again it depends how strong the fragrance one has used and what are the components that make up that fragrance, many are easily soluble in water/ethanol solution while others need a solubilizer at the same water/ethanol ratio.

[Chemist77]

@Belassi I think it might give you a little advantage if you use ethoxylated form, and which would of course be less irritating compared to non-ethoxylated although. Secondly ALS has a lower CMC compared to SLS and hence it is a more effective cleanser. Enter the ethoxylated ones and you have a little less cleaning and I am guessing a little less dry.

[Chemist77]

While agreeing with @Perry I would do my first trial without the solubilizer to check if ethanol is enough to keep the product clear and transparent. I am guessing 3% fragrance won’t be an issue for 60% ethanol. 

[Chemist77]

First of all if it is in % then it should add up to 100 which is not the case here, secondly where is the fragrance (whats the percentage) and with so much ethanol why you still need the solubilizer. Last but not the least try to reduce the glycols and panthenol to bare minimum if you want that non-sticky feeling without the drying effect of ethanol. It’s just a splash, keep it simple. 

[Chemist77]

@Perry To begin with beggars couldn’t be choosers, and if I need an info there is a way to ask and if someone denies it that doesn’t mean I have to show this kind of street urchin behavior. 

Thanks

@Perry

As a moderator please inform this lady that this forum is for civilized opinion posting and not for spoon-feeding, I could retaliate but this is against the decorum of this forum.
Hope you take a suitable action on this and warn against such street character behavior.

Thanks

[Chemist77]

@nasrins No offence but my post is pretty self-explanatory for a person who has a little know-how of very day today chemicals used in emulsions.

cheers
