Dissolution Consultation Retinaldehyde

Postby joelfonat » Thu Sep 15, 2022 10:33 pm

Retinaldehyde 0.1%
UltraSolve 3%
ActiveProtec UV 1%
Followed as admin suggested, but it didn't dissolve, so it reduced to 0.03%, still not dissolved. So the heat is melted, which really do not know if it should be heated or not. If given, it must not be more than a few degrees (but it doesn't really melt)


Adenosine 0.5% is soluble in water, it cannot be dissolved. So I heated it, put Propylene Glycol , Ethoxydiglycol , --> completely dissolved until clear --> put a liquid bottle into water --> later it was precipitated.

So I did it again, but this time --> when it's done, use Sponge Gel . After refrigerating it, it settles in the bottle a lot.

Clover Flower Extract (Biochanin A 98%) 0.5% --> soluble in isopentydiol 5% is insoluble. But when heated, it melts. But I really don't know if it can get hot or not.


In conclusion

1. Retinaldehyde Can't get heated? But it doesn't melt. What should I do?

2. Adenosine will be made into a slap water. Do I need to find a way to prevent it from settling down? / Even if it's made into a gel, it still precipitates. But in my heart, I want it to be more of a slap.

3. Clover is another one that is very difficult to melt. I really don't know if it can get hot or not.

hello


matter of solubility It's a very detailed story.


story example Retinaldehyde , as asked, is that the method of dissolving is correct. And a little help with heat may be necessary. and used in the shortest possible time If no heat is required at all, a special tool may be required, for example an ultrasonic homogenizer .

using heat makes Retinaldehyde You can definitely lose quality. but the quality loss Not all at once but to accelerate the deterioration at a faster rate If using the shortest and lowest heat, it may deteriorate a little. In the production of large quantities, heat is usually required. But the heat control system may be accurate, for example, using only 50 degrees is enough. Once melted, then immediately cool down.


Adenosine is insoluble in water, having a highly hydrophobic character, although it is soluble in any solvent when added to water. It will become a precipitate immediately. In mixing, it must be blended. Adenosine is dissolved with solvent and mixed with the oil in the formula, then mixed with the water part. at a temperature of 70-80 degrees

Adenosine is more heat resistant. Very Retinaldehyde


Clover Flower Extract is heat resistant much better than Retinaldehyde . It can be heated sparingly and melted until clear, but use it sparingly.
