Hi Everyone, Thanks for the advice. The only thing that changed was a fresh batch of NaOH (10% solution made from granules). Same batch of granules. I have checked all of the RMs and nothing has expired. I will dispose of the NaOH solution and t…

Hi Microformulation - the pH is high because it is a product designed for dogs. Dogs have slightly alkaline skin so acidic products like those for humans cause irritation.

Good to know! At my day job (at which I only have 8 days remaining - it is a dodgy outfit so I am moving on) they use the term uv filter in a cream with only SPF1.2 i.e. diddly squat. I will do a bit more brainstorming and market research re termi…

Hi Andy, I live in NZ and often come across issues where a company will not ship outside the US. There are now companies such as http://www.ship2me.com/ where you get your parcel delivered to them at their US depot and they will then forward it on t…

Thanks for the advice guys - the licking factor is something I keep in the forefront of my mind. I have a paw balm which is becoming a wee bit of a cult item - and I made sure that everything in that formulation was safe to eat. (Not that I could im…

a really helpful tool which I use as a guide is the BASF calculator https://www.sunscreensimulator.basf.com/Sunscreen_Simulator/

@belassi I really enjoy reading about your experiences in the lab

@milliachemist I did a quick swap at 1:1 - it was not a 100% match but gave a less greasy feeling product which our customers seem to like. Very very short notice project i.e. we have told our customers that the products are now silicone free - we …

I have had good results replacing dow corning 1401 with isoamyl laurate

It would probably be helpful if you posted in English...

Thanks for the confirmation Bob. eperfumes - looks like the hubersorb 600 is being used for a deoderant - I was looking for an antiperspirant - thanks for the link though
-
Thanks Ozgirl. I am in New Zealand but we export 90% of our product to the US. Looks like I am going to have to really push back on marketing - they will have to decide which claim they want to make - antiperspirant or aluminium free.

Hi Bryce, You will need some kind of acrylic co-polymer. I use Aculyn 33 or Carbomer Aqua SF-1. Sarah

I had an email from a supplier yesterday stating the following: “Please be informed that the enclosed press release was sent out to journalists last week. Earlier this year, the Scientific Committee for Consumer Safety (SCCS) assessed the use of ti…

I am looking into formulating products for dogs - in addition to the neutral pH is there anything else which should be taken into consideration from a safety perspective? I am using the old fashioned suttocide preservative b/c it is effective at pH …

brilliant - thanks Mark - just what I was looking for :)

I have used a product called Betafin BP 20 from Lonza (INCI Betaine) in some of my gel products - it leaves a lovely soft and smooth skin feel.
-
@Matt, I have had the product tested at 6,12 and 36 months with no issue. As I mentioned we also use Totarol and the product is packaged in tubes with a pump which does not allow any air to seep back in. We use loads of ethanol to sanitise everythin…

Hi Mark, The totarol is quite different to the biovert. It is an extract form the totara tree here in NZ. The INCI is: Podocarpus (Totara) Extract Not sure why we use both systems - the formulation predates me. CheersSarah

Hi, We actually use this preservative system in our super '"natural" range. It is a product called Biovert by Lonza. * A two-component protection system * Mimics a naturally occurring antimicrobial-antioxidant protection system * Offers b…

Are the companies pulling TiO2 out of all of their products or just the powdered mineral make up formats? i.e. if a sunscreen contained TiO2 would the manufacturer have to put up the big warning display in store? I'm a Kiwi and our company is just…

correct

We add benzophenone-3 to our shampoo to slow down the colour degradation in the product itself.

@Bob - what a fantastic resource!

Check out AliExpress - they do small volumes

Hi David, This has been an incredibly painful project - it has been ongoing for more than three and a half years! Communication is not the customer's strong point. I have decided to completely reformulate (again) - luckily I managed to stop the artw…
-
Our marketing department did a google search to find the top ten baddies and based the 'free from' claims based on this list. I now have to formulate around these claims.

Hi David, We use a product called Myoxinol LS 9736 from Cognis for tightening in our eye serums - it is a bit pricey though.
