klangridge said:As above - if it’s appearing over time it’s likely microbial growth. Bear in mind that whenever you use “natural” ingredients, they are likely to contain a higher concentration of microorganisms than traditional, synthetic materials and therefore need higher preservation. However, if you can find a way to sterilise before use this may also help.Thank you! I would like to try the Euxyl® PE 9010 (Phenoxyethanol (and) Ethylhexylglycerin) from Lotioncrafter to preserve this formula. Can anyone let me know if this seems appropriate? I understand it will provide broad spectrum preservation up to 12 PH. However it may be mild. Will it result in clear formula? Thanks

ngarayeva001 said:Can you use formaldehyde releasers? Germall Plus is a great option. It will not cause cloudiness unlike many other preservatives. Re hydrosol, ideally you want none of it and as little aloe and cucumber as possible. Flower waters are source of contamination. It’s hard to preserve them (as well as plant extracts). So if you want your product to last and be safe you either need to rethink how you will achieve the right smell or add a strong preservative (formaldehyde releasers or parabens or both)
Ok thank you I will re-think the preservation. Id rather not use formaldehyde releaser though.
UPDATE:
Experiment 1: 100% distilled water (different water) = clear
Experiment 2: 100% distilled water (same water I was using before) = cloudy
Experiment 3: 100% rose hydrosol (same I was using before) = cloudy
Experiment 4: lowered formula to 20% Hydrosol and used new distilled water = clear -
ngarayeva001 said:It could be bacterial contamination. Your product isn’t sufficiently preserved. Phenoxyethanol is not a broad spectrum preservative, it doesn’t cover mold. You also don’t have enough of it provided presence of bug food extracts.
Would supplementing the Phenox with 2% of Leuconostoc/Radish Root Ferment Filtrate provide broad spectrum preservation? I also have Optiphen plus here however have never used it.

Fekher said:@CarrieM actually as answer for your 3 questions according to me
1) there is always an order for better process or product for your case it is not really important
2) I guess that your product from lol supposed to be clear but if there is a suspect it will be about extract may the quality change from buying to other.
3) Your formulation have good ingredients really , just two things for verifying: is the viscosity good for serum then if your product is stable (preservation is it fine?)
Thank you for your comments! The viscosity works for this as it is a spray application. I understand my preservation is insufficient however and the cloudiness could be due to contamination.

ngarayeva001 said:I have just noticed it’s 78% hydrosol! Very likely contamination.
That is very interesting and suspect. I will attempt using just water or another batch of Hydrosol. Can I ask, what is a typical % of Hydrosol for a formula such as this? I kept increasing the % because I wanted the rose scent. Regarding the preservative, can you recommend a second one that I can add to tackle the mold? Thank you for your comments!

The resveratrol is solubilized in the Glycerin (which I love as an ingredient as well). thank you!
-
Oh yes thank you for pointing this out to me. The MAP would not work here.

(I meant point #3)

Thank you! point #4 may be why the result was so thin when just using the Gel Maker. I am unclear about how to determine if an ingredient contains electrolytes.
Regarding the Vitamin C, I read that the PH ranges do overlap. In any case, I’m considering replacing them both with Magnesium Ascorbyl Phosphate which requires final Ph between 6-7 (which would work with the Niacinimide).

Ok so Squalane may not require the vitamin E but if it did a ,01% may be sufficient … I’ll spend some time trying to understand Squalane better. After reading your point #4 several times I’m only still only half understanding because I am not a professional
but Ill be doing some experiments because I do have 165 and aristoflex and would like to see how that system works.I did initially have a gel cream in mind but using just the Gel Maker did not result in a thick enough product. I suspect after reading <b style=”background-color: var(-bb-content-background-color); font-family: inherit; font-size: inherit; color: var(-bb-body-text-color);”>jemolian’s comment that could actually be due to the inclusion of 72h moisture and the glycan booster peptide so I’m going to try a version with the Gel Maker but excluding those two ingredients.
This is all so helpful thank you

Hi there thanks for this..
1. The formula includes both c13-15 Alkane at 5% and Squalane at 5%. The tocopherol is needed to protect the Squalane, right?
2. I have TSGD so will add this
3. I need to double check the PH with regard to the vitamin C!
4. Now, I’m as stumped as you! I initially was making this as a gel cream and only using the Gel Maker EMU. I decided to try to thicken it and so added the Cetearyl Alcohol. I actually like the result but am certain it wasn’t the proper avenue to achieve a thicker, creamier result. What should I have done and perhaps I go back to drawing board and not even use the Gel Maker

Thank you so much! Great points that I will consider for the next batch. I did think the two forms of vitamin C I included were the more stable forms (i.e. NOT L-ascorbic acid). What I’m definitely unsure of is which form of the more stable Vitamin Cs is the most effective. These two I just had on hand so I used them.
