@Belassi
I do agree with you

in Malaysia…10% Erythrosine solution in Aqua will fade away within a week
(condition : room temperature, Storage : Office table without direct sunlight)

@chemicalmatt
I’ve been using Cibafast since 2005 and facing no problem at all with colour stability. But this time, I also wondering what is behind the colour stability issue.

In the formulation, I just collaborate SLES, SLS, Betaine, PQ7, Kathon CG (Preservatives), Fragrance, Cibafast, and Colour.

As per mentioned earlier.. I use Cibafast in almost every formulation without any colour stability issue…

Now..I try on to increase the Cibafast from 0.03% to 0.06% and run the colour stability testing.

will update here the results in few weeks.

thanks @georgiax  

will contact the sales person for sample

[yongnn30]

Thank You all

I will change the colorant and find the most convenience uv stabilizer to delay the color change.

I have

1 sample expose with lighting in Display Cabinet
1 sample keep indoor on my office table
1 sample stored in uncontrolled temperature (which can exceed maximum 50 degree Celcius)

only indoor sample remain the original colour while the rest fade

Sir

I am using 0.001% of Brilliant Blue and 0.003% Carmoisine

Our facilities Water source treated, and we have Reversed Osmosis Water and Deionized Water. For formulation mentioned above, I am using Deionized Water

[yongnn30]

Yup… Agreed …

[yongnn30]

Thanks @MarkBroussard… you are absolutely superb!!!…

I have to start from basic and analyze everything in the formulation before start it all over again…. by considering everything you just mentioned… Thanks once again

[yongnn30]

I see…. Currently we are using Sodium Benzoate to preserve toothpaste at pH7 to pH8. Since our new customer asking for natural toothpaste (with premium quality) we are considering something that Natural/safe/less irritant. So our team decide to come out with everything Natural in the formulation (its totally crazy to deal with this kind of formulation)…. the final idea, toothpaste without preservatives or with natural preservatives…

@MarkBroussard… do have any idea on SLS or Sodium Lauroyl Sarcosinate substitute?… for this moment we have Lathanol (inci Sodium Lauryl Sulfoacetate) and Sapponin Complex but we looking for more option for Natural surfactant

[yongnn30]

OMG!!.. Thanks @MarkBroussard… Will stick to second formulation (without any preservatives) and monitor it while searching for alternatives Of Saliguard EZ

[yongnn30]

Salute Perry for this amazing site.. I’m not good in English, sometimes its hard to find words to share it here but trying My best to communicate with others. I am happy to share and learn from everyone… Thanks Perry… Thanks everyone

[yongnn30]

@MarkBroussard.. The material that I’m using to claim as preservatives free for My Natural Toothpaste formulation is Saliguard EZ, compatible from pH4 to pH9.. Inci name propanediol & ethylhexylhlycerin..

The second formulation, we try it without any “preservatives”… Million Thanks to @MakingSkincare for the superb idea… Tough day to go towards accomplish this task…

[yongnn30]

My Supplier send me sample of natural preservatives that work within pH 4 - 9…also can claimed it as preservatives free… I’m going to try it on next week and update it here

[yongnn30]

@Belassi..yup you are right..it is an expensive way to treat skin but Asian women really like it..(maybe women in asia don’t have time to pamper skin at SPA)..so marketing keep claiming that sheets mask can be the best way for D.I.Y SPA)… i do agree with @pma..that is the most popular items in Asia..

[yongnn30]

great @milliachemist…your comment reminds me to Transcutol from Gatte Fosse.. transcutol also helps carry actives into skin… maybe you can try transcutol in your formula @belassi while waiting Averes reply me

[yongnn30]

@Belassi..Sebaryl info for you

 http://www.bsibusiness.com/uploads/product_ls/pdf/136_pdf.pdf   

My lab senior use the material to cure oily scalp in Hair Tonic but he end up with finished product colour change issue

[yongnn30]

@Belassi… i’ve heard about actives that help skin penetration for gel based..it’s from AVARES… but unfortunately I forget the actives …I’ll try to asked sales rep. and come back to you soon

[yongnn30]

(I got the copy from CP Kelco sales rep. since the page is inaccessible for Asia User)

[yongnn30]

@Zink..maybe you can add binders/emulsifier..

Emullium delta from Gatte Fosse..it’s compatible to high pH

[yongnn30]

Superb @MarkBroussard .. it helps in my current project; edible hand and body lotion ( actually it is safe cream to apply on baby & mommy skin)….the idea comes from my customer who wants something different for her product range…

[yongnn30]

@ChemWizard

For Instant Skin Tightening…Hydrolyzed Soy Protein (actually meant for food but it works well to give instant feeling)….. at 5% would give perfect Serum collarborate with hexapeptide and etc as (long terms anti aging actives)

[yongnn30]

My experience on doing Clay Mask (a few years ago) using White Clay form Malaysia.. I try to maintain pH at pH6.5 and I’m using 0.5% alllantoin and 0.6% Portulaca Oleracia Extract as anti -sensitive agent… feed back from my customer, they like the texture and it works on sensitive ski

[yongnn30]

Thanks for good information @milliachemist & @Bellasi… I will ask Lubrizol rep. to provide me more info on SF-1

[yongnn30]

Interesting @milliachemist…

 i found that it’s hard to find good suspending agent in Malaysia ..
