Re: Preserving Goats Milk Lotion

[Guest guest]

Dana:

This info comes from Welch. I am only passing on what she gave to me.

Disodium EDTA to preserve the goatsmilk. She is away this weekend with her

goats at a show. She makes goatsmilk lotion. I am not sure where she gets

her Disodium EDTA or levels to use along with your other preservatives. I

just wanted to let you know that she has pres. it successfully.Maybe others

will jump in here and help us out!

I was also interested in what had to say. Here's what she

posted last month:

(Did anyone find a place to purchase smaller quantities of the

disodium EDTA?? Thanks!

I've been making goat milk lotions for three years now with some

success.

When I first started, on the advise of a cosmetic chemist (known to

this

list) I used no more than 10% goat milk in my lotions and they were

still

tricky to preserve (mold being the most difficult culprit). I believe

trying to preserve a product with 100% milk as your " water " phase or

even

50% milk in your water phase is too much for any preservative to

handle

effectively. I have had the greatest success using Phenonip as my

preservative at 1% and using Disodium EDTA as a chelating agent

(which works

to increase preservative efficacy). I hold my water and oil phases

at 170°F

for 20 minutes which helps to kill any mold spores. I also use

Malibu tubes

for my product which lessen the chance of consumer contamination.

Hello Fiona,

I did email Jen privately before I asked the list because she has helped me in

the past. She sent me some great info about Disodium EDTA, here is the link she

sent me for purchasing it:

http://www.sciencelab.com/Merchant2/merchant.mvc?Screen=CTGY & Category_Code=10412

She also told me she has never used Liquid or Powdered Germall Plus so she could

not comment on the effectiveness in difficult to preserve emulsions, hence my

questions here =)

I have not had my formula challenge tested ... quite frankly I have not had the

money. But, I am going to have to seriously considered doing some informal

testing (sending out several for APC counts that have been abused by us at home

after we know the batch was clean to begin with) to see about effectiveness.

Maurice, do you still have the list of labs that will do APC counts?

Thank you,

I use the powder only but you should be using more for the liquid, although I am

not sure what it is as I use the powder which is much higher concentrated and

IMO better since it has not been diluted.

With the powder I use .2% (which is the highest amount) and i have no problems

with using 95% goats milk in my lotion.

here are the specs for the powder, I cannot find anything at their website on

liquid since it is NOT sold in liquid by the manufacturer, personally I would

not trust any diluted product (preservative), how can you be sure the supplier

you bought the liquid from diluted it properly?

significant amount of proteins and/or complex ingredients, 0.2% of Germall Plus

They do? Hmm, I never saw it on there..

Well then for sure whoever posted about it earlier should go there and make sure

they have the % correct for what they are making. I still prefer the powder as

it is more consentrated.

But mainly what my point was, is that people buy the powder and dilute it, that

is what I do not trust.

Karla,

ISP Sutton markets Liquid Germall Plus. Their site needs updating; the

information is in their brochure (Preservatives for Personal Care) which you

can order from the site.

The recommended usage rate for Liquid Germall Plus of 0.1%-0.5%, according

to the brochure.

Hi Dana and All,

I have to agree with you. I used to use the powder, but had a terrible

problem with it clumping. I personally find the powder more difficult to

incorporate into emulsions. Steve at ISP recommended using some glycerin or

propylene glycol to mix it into first to make sure it is well

dispersed--which is a good idea for those of us who use glycerin in formulas

anyway...just save a small portion for the Germall Plus. The powder is also

somewhat more difficult to weigh accurately since it is so light weight. So,

to me those are all good reasons to use the liquid germall plus.

I have been to ISP Sutton and am very aware of the maximum recommended usage for

Liquid Germall Plus by ISP Sutton. It's .5% As for the powder, it may be more

concentrated, but you are using the same amount of preservative as I do when I

use LGP because my addition percentages are higher with the addition of

Propylene glycol to the formula. I have tried the powder, and while it takes us

less space in my inventory I battled with clumping due to humidity.

Thanks,
