What improvement do you believe boiling the water will deliver? If you read about sterilization, you must have pressure and heat. Use validated water and use a robust preservative system. You aren’t performing sterile manufacturing. If you ever worked in a clean room or a laminar flow hood, you would see that it is fruitless to attempt sterility. Be sanitary.

I can’t say too much, but their is a patent issue. The company never really got off the ground. The partners are adjudicating the company and property of the patent.

I have salicylic acid in house in powder form. Any suggestions on the solvent i can use to dissolve it without altering the viscosity of the body wash?
In the end, these invalid claims will affect you client and limit their growth. We won’t touch a product unless it clears Regulatory.

Any suggestions?Don’t make any acne claims at all anywhere in your marketing or product descriptions at all.It is pricey, but we use Salspheres from Salvona.

Affecting the final skin feel can be addressed through other measures such as rapid spreading emollients for example.

Solid syndets are a niche product, albeit they are getting more attention due to waterless/low water sustainability concerns. Susan Barclay Nichols (swiftcraftmonkey) has a great deal of information in her blog. If you are looking for practical Formulating info, you should check out her blog.

No. Where did you get that?

KimberlyLars said:@Microformulation thank you for the feedback. I found their formulation tips to be unhelpful as I did exactly as instructed with no success. Thank you for providing the sample formulation.
I have used the product numerous times and have had no difficulty getting a homogeneous product with an overhead stirrer. (IKA Eurostar Digital).

Curoxyl 42 has an INCI name of Water and Benzoyl Peroxide. There is a very good guiding document available for download here; https://www.ulprospector.com/en/na/PersonalCare/Detail/705/217985/Curoxyl-42?st=1Off-hand and from experience, you will likely need a better emulsification system.

I would suggest that perhaps you change your source of reading materials since it appears you are getting some incorrect information.
Glycerin is not an emulsifier.
Glycerin is water-soluble.
Thank you, as I mention it this product confuses me because I use butter and carrier oils with glycerin and it dissolves beautifully.
Could this be because I do cold produce?I would wager that if you did stability in a formal manner, you would see the glycerin separate out over time. -

mikeylamar said:Microformulation said:Why Baking Soda?
This will be a DIY serum and the baking soda will be used to lower the PH
Baking soda is never used. There are much better ways to adjust pH. I would seek greater understanding. In addition “Baking Soda” (NaHCO₃) will RAISE you pH, not lower it.

MarkBroussard said:This is a cool concept, but in my experience, is not suitable for a commercial product. The process to form the gel is tedious and it does not work with all carrier oils … works better with saturated oils, not so goog with unsaturated oils. Generally, the gels are not heat stable. Next.
That has been my experience in scaling up these Formulas. They are difficult to perform on the manufacturing floor. Most Contract Manufacturers I know avoid this raw material.

I have made several. Essentially you are looking at a good gentle base with the addition of several botanicals for anecdotal “claims.”

All of your butters have some greasiness to them to some extent.

As @PhilGeis has mentioned numerous times, Period After Opening (PAO) is a useless term and standard.This would be established through testing. Each Formula could be different. You really can’t guess.

Emotelle said:I think when customers see the word “phenoxyethanol”, they freak out thinking it is some alcohol that will harm their sensitive skin.
Not in my experience. Any push back I have seen was from distributors who felt it wasn’t natural. That is based on 100’s of Formulas with PE9010.

kabilboy said:I don’t know bout your air freshener, but I also have a wonderful homemade spray recipe that you will love! You should add about 25 drops of your favorite essential oil to 2 tablespoons of baking soda and stir to combine. Lemon and lavender are excellent choices, but eucalyptus is my favorite because of the refreshing scent. Pour the baking soda and essential oil mix into the water and stir. Then funnel the water into your spray bottle. Seal tightly and give the bottle a good shake to combine ingredients thoroughly. This works wonders, I swear! I use it as a smoke odor eliminator car.That “recipe” needs some technical work before you could even consider it a Formula. There are so many issues.

Aw can’t be easily adjusted and quantified. I have seen it done, but honestly it was in Food Science, not personal care. From the same presentation;
