Preservative
I’m making a body scrub with oils. I’m a crafter. I see lots of conflicting information about the use the use of preservatives in products that contain no water. Do you think I need one? I have tried looking at other professional brands to check but it seems they don’t use one. My recipe is basically oils salt and an emulsifier. I’m in the UK, I pay for my assessments. Thank you : )

Salt can also act, depending on quantity, as preservative
.If one uses your scrub, does it get wet and stay wet for a prolonged period of time like a piece of soap in the showers? If yo, then you (or rather your consumers) are better off with a preservative (by preference, one strong against fungi). -
I need your support about my multi-purpose detergent formula (laundry, surface and dishwaching liquid) using MICT/MIT as preservative
I am looking for the right and effective dosage of this preservative for these types of formulas
The pH of our formula is between 7 and 10.5
I used 0.06 % of MICT/MIT but I can not known that this dosage is effective -
Tyss, first, this is a cosmetic chemist group, not a domestic products group. Secondly, it is not good manners to jump into someone else’s question with a completely unrelated topic.
Third, I do hope your product will not come in contact with skin, not with that preservative. -
Dear Belassi,
First of all thank you for your answer.Secondly, I know that it is a group for cosmetics. However, I have seen several members who are asking for help with their detergent formulas.Third, I do not see that I jumped into the question of other people, since my subject is about the Preservative. But on the other hand, I apologize to everyone.Finally, it’s not good to attack people in a public forum and especially people who really ask for help, is not it? -
@Tyss - Thanks for your participation. I think what @Belassi was trying to do was to encourage you to start a new discussion. While I’m sure you didn’t mean it, your new question diverts attention from the original poster’s question and that is a bit unfair to that person. It would be more appropriate to start a new discussion. There’s a button on the right column to do that.
Belassi also is not a fan of MICT/MIT as a preservative due to known problems of sensitization. It is mostly banned from leave-on products in the EU and highly restricted in most rinse-off products.
MICT/MIT is used at 7 - 15ppm so your use level is quite high. But is also not stable over a pH of 8. Whether your use of it is effective can only be determined by a microbial challenge test.
