Yes, fragrance can certainly be a problem. You might need to solubilize it before putting it in your formula. Use something like Polysorbate 20 or Polysorbate 80
-
You’ll need to be a little more specific. What are you hoping the product will do? What claims do you want to make?
-
Companies that sell raw materials are marketers. Just like all marketers, you can’t completely rely on the validity of their claims. Do these compounds contain ceramides? Who knows? It’s possible they have some analytical instruments that are able to detect tiny amounts of some material that they call ceramides. Typically, these companies don’t blatantly lie (although some do).
More importantly does the presence of ceramides in these ingredients have any impact on the performance? The answer to that one is easy…No.
The only reason ceramides are even mentioned is so people who use the ingredients can claim their products have ceramides & consumers will then believe the product is somehow special because of it.
It’s really just a marketing ruse that has no impact on product performance.

Yes they can sometimes be mixed together but sometimes they can’t. It depends on your system & what you’re hoping to achieve by blending the ingredients.

You certainly can have PQ10 and Guar polymers in a formula together with an ionic surfactants. That is unlikely to be the problem.
More likely is your esters fell out of solution (those don’t belong in a shampoo) or you have a microbial issue. My first step would be to try again but remove those esters.

3% x 45% = 1.35% of ing Y
3% x 55% = 1.65% of ing Z

Another question is, why everytime i make formula that consist SLES (Texapon) and HEC, the final product always separate after 1-2 days?
Probably because the HEC is not properly hydrated.

A freeze/thaw test cycles between hot storage/RT/cold storage/RT. It is meant to mimic what might happen in shipping. So that’s why you may be able to reproduce the results.

When I was working on the VO5 shampoo brand you could get a bottle of 16 ounces of shampoo for $0.99. That price remained steady throughout the 1990’s and into the 2000’s. I just looked it up today. Here in the US at Walgreens you can get VO5 shampoo for $1.00 for 15 ounces. It doesn’t seem like the prices have changed that much. And if you adjust for inflation, the price has gone down!

The primary function of both foundations and concealers is to even out skin tone and provide coverage, but they are a little different. Here’s a breakdown:
-
Purpose:
- Foundation: The primary goal is to create an even base. It can be sheer, medium, or full coverage, but it’s typically spread over the entire face. A foundation’s main objective is to make the skin tone appear consistent and smooth, but it might not necessarily cover every imperfection.
- Concealer: Specifically designed to hide blemishes, dark spots, and other imperfections. It’s often thicker and provides more coverage than foundation.
-
Pigment Concentration:
- Foundation: Contains pigments, but typically at a lower concentration than concealers. This allows for buildable coverage, so users can decide how much they want to cover their skin.
- Concealer: As you observed, concealers generally have a higher concentration of pigments, and often more opacifying agents like Titanium Dioxide. This gives them the ability to effectively cover dark circles, redness, and blemishes. The higher concentration of Titanium Dioxide makes the product more opaque, thus offering better coverage.
-
Texture & Consistency:
- Foundation: Available in a variety of formulations – liquid, cream, powder, stick, etc. The consistency varies based on the type of foundation but is generally formulated to be easily spreadable over the entire face.
- Concealer: Typically thicker in consistency than foundation. This allows it to stay in place over blemishes and provide lasting coverage.
-
Application:
- Foundation: Applied to the entire face to create a uniform base.
- Concealer: Applied only to specific areas where more coverage is needed.
It’s worth noting that there’s a trend in the makeup industry towards multi-use products and customizable coverage. As a result, the line is getting a little blurry between foundations and concealers. However, the traditional distinction between the two, especially in terms of pigment concentration and coverage, remains as described above.
Your observation about the higher Titanium Dioxide concentration in concealers makes sense when you think about the product’s intended use. Titanium Dioxide is used for its opacity and whitening properties, making it excellent for covering imperfections.

It depends on the claims you want to make and environmental regulations. In California, for example, I think you are compelled to include some water in a product like that. I don’t know all the VOC regulations there but if I recall you likely can’t have more than 55% VOC so water is required. In an ideal world, the Alcohol alone formula would deliver the fragrance and evaporate off the most quickly without negatively impacting hair.

It’s hard to say without knowing all the ingredients. I’d suggest you at least list those.
But there are a couple of possible explanations. First, if the balm experienced melting and then reforming during shipment, it’s possible that the top layer became enriched with beeswax, resulting in a harder texture. Make sure to mix the balm thoroughly during production and maybe instruct the customer to check the balm consistency deeper into the container. Another thing is that it could have cooled too quickly. If this happened and the wax and oils crystallized at different rates, this might result in a firmer texture. You could see if either of these is the case by doing a freeze/thaw stability test. -
ULProspector is my default choice but I use knowde and specialchem
-
I see no acid in there. What is the pH? Those organic acid don’t work as preservatives above around a pH of 5.0
-
You probably can’t. It might help to know what ingredients are in your whole formula
-
My guess is that your preservative system is not good. Sodium anisate/dosium levulinate is not a proper preservative. At best it is a preservative “booster”. That you passed previous challenge tests means you were lucky or your testing wasn’t suitably challenging. Almost any material can have contamination, not just sodium hyaluronate. I’d recommend putting in a proper preservative.
-
It depends on the formula, fragrance, other ingredients, and the cost you are willing to have. More water means it takes longer to dry. More alcohol means it will cost more and may be in violation of VOC regulations.
-
This is why people should generally buy from Big Corporations rather than small, indy beauty brands. Big corporations do not skip tests and are the most safety tested products on the market. Some smaller companies are often underfunded and just assume their products are safe without testing.

While ChatGPT can be helpful it can also be incredibly misleading. I wouldn’t put much faith in anything factual that it tells you. It has been trained on things written on the Internet which have a wide range of factual accuracy.
The problem with your question is that there is no simple answer. HLB is a helpful guide but the numbers make it seem more precise than it actually is. Just because a number is placed on a characteristic doesn’t mean it is accurate or predictive.
Also, your simple classification of “emulsifier” and “oil phase” is not accurate. For example Cetyl Alcohol will have an impact on your emulsion particles. So will Stearic acid. Carbomer will also impact emulsion stability which is what you’re really interested in. This is not taken into account when using the HLB system.
Bottom line…systems are complicated. HLB can help clear things up but only in the most simple systems. The one you posted is not simple & HLB will not be helpful.

And those people are wrong. The price of a bottle of shampoo has almost nothing to do with the quality. In fact, some companies may take exactly the same formula and sell it under a cheap brand and an expensive brand. Same formula, different branding, position & price.

I’m just curious why there are radishes and cilantro in the product!
-
Yeah, evaporation happened!
-
Agreed. It is standard practice (or at least should be) to do a microbial check on pretty much every ingredient you use.
