In my experience all fragrances fade overtime, some faster than others. One cause of lost of fragrance is oxidation, avoid light exposure, store all soaps and soap noodles in a dark container.
Rancidity will also affect scent, but when this happens the soap will develop a brown color.
Some people recommend adding arrow root powder to the fragrance before adding it to the soap, I personally did not notice a significant difference.Some fragrances just perform better than others in soaps.

@chrystad72 CIR has regulations for liquid surfactants shampoos and liquid cationic surfactants for conditioners, but there are no regulations for surfactants and cationic surfactants for solid products which is a problem. When you use a shampoo bar or a conditioner bar, they are more concentrated, but it does not mean the exposure is any different, since when you use a bar you use a lot less product to begin with. This is something I found to be problematic. Regulations need to address this challenge since disposable plastic bottles will eventually be banned. Hotel sizes have already been banned in California, but this is just the beginning.

Our oceans are full of plastic, and microplastics, it is heart breaking to hear about its effect on marine animals.

No wonder some consumers are concerned about the presence of Petro chemicals in their cosmetics…. They want change; chemical free, natural and sustainable!
The subtleties of cosmetics chemistry and its preservation challenges are too complex of a subject to resonate with the masses. As a consumer It takes dedication, research, and a magnifying glass just to understand and recognize basic cosmetic ingredients on a label.
I agree that consumers should be protected with an official definition for natural and optimally a rating system for natural, but also for sustainability so consumers can buy products that reflects their values. Maybe a cosmetic safety rating should also be used….

Eye cream targets the thinner skin around the eyes that can become puffy. Some people are promoting the use preparation H because it is a corticosteroid with anti inflammatory properties, but like all corticosteroids, the side effects are skin thinning which is not a good.
You want to make a non greasy cream that spreads easily, is non greasy and contains anti inflammatory ingredients like coffee extract which is without side effects. -
yup! Mark is correct, lanolin is an ingredient by itself that is fat soluble.

From my experience, if your shampoo bar is well made, the friction is minimal and should not cause hair damage. You only need to gently glide the soft surface bar on your head, no rubbing necessary whether it contains cationic surfactants or not. The second question; usually the cationics in a bar are at a single digit percentage in contrast with anionics who are at least at 50% concentration. It is possible that they deactivate each other, but I have not noticed this effect since the ratio is so loop-sided. A small amount of cationics in the bar seems to enhance the texture of the foam. You can test this hypothesis yourself by making a bar that contains equivalent concentration of anionic and cationic.

In this formula they have a some water soluble ingredients like lanolin cucmis salivus (cucmber) fruit extract and citric acid probably solubilized in the extract. It must be at a very low percentage.
-
@natiyo123, water soluble ingredients are not compatible with oil/wax stick.
If you want a preservative and a chelator, look at what the major brands are using like Burt’s bee if you are making a lip balm.
Helianthus annuus (sunflower) seed oil, cocos nucifera (coconut) oil, beeswax, ricinus communis (castor) seed oil, natural flavor, lanolin cucmis salivus (cucmber) fruit extract, menthe piperita (peppermint) oil. Theobroma cacao (cocoa) seed butter, butyrospermum pakii (shea) butter, carthamus tinctorius (safflower) seed oil, glycine soja (soybean) oil, tocopherol, citric acid, rebaudioside A, limonene, linalool -

Thank you! I bought some light pink Colorista from Clairol and it worked. It enhanced my brown hair to an auburn like color and colored unevenly my small amount of white/gray hair. I like it and will probably try to make my own. It also made a pink mess on my white towels.

@Graillotion, I also wondered the same thing. I noticed that 30/70 is the most common, it is also less expensive. Ingredients to die for located in Texas is the only supplier I found who sells both in small quantities. They say “The 30/70 blend will create a stiffer emulsion than the Cetearyl Alcohol 70/30 will”.
If you are looking for a softer emulsion then look at Cetearyl Alcohol 70/30 or Stearyl Alcohol

@tecnico3vinia, there was discussion on the subject recently.https://chemistscorner.com/cosmeticsciencetalk/discussion/8973/ethanol-as-a-broad-spectrum-preservative

Castile soap is alkaline PH of 8.9, this opens the hair cuticle which can cause damage and breakage. You need to rinse with alkaline solution (vinegar) or use a conditioner to minimize damage.

By the way this company’s products were recommended by the NY Times Wirecutter as best shampoo for dandruff. https//www.nytimes.com/wirecutter/blog/ethique-shampoo-bar-review/?ds_c=71700000087595749&gclid=CjwKCAjw7IeUBhBbEiwADhiEMcVZ5HCS77wf12cKgklZlDZwiXr0l_seUBtANz_GhBs91eGLMMMiGBoCUOkQAvD_BwE&gclsrc=aw.ds
They were promoting their St Clements shampoo bar for dandruff containing citrus oil. I wrote the Wirecutter explaining that dandruff shampoo was OTC in US because seborrheic dermatitis is a medical condition associated with hair loss and asked about clinical trial for citrus oils. It appears that they have removed the product from their store…

@Perry Then would this product be considered in violation? https://ethique.com/products/tone-it-down-shampoo
This shampoo bar contains beetroot extract for blond and silver-fox hair to reduce yellow. It has been on the market for several years…. -
I would try this pigment based on beetroot:https://www.makingcosmetics.com/PGNA-BEETRT-01.html?lang=default

To do fermentation you need carbohydrates, are carbs present in olive oil? It is possible that a very small amount of olive pulp remains in the olive oil. This is the only explanation I could come up with, maybe someone else will have a better explanation.

@ngarayeva001, I agree with you. Unfortunately these days influencers (DIY) are following in the footsteps of the Kardashians and the mother of DYI Martha Stuart for riches and fame. There have been many recalls of hand sanitizers over methanol during covid. This probably worried a lot of people. This issue made it a good target for DYI with its own unfortunate consequence.

There are complementary sunscreen ingredients like Meroxyl.

@mikeylamar, a patch test is overkill. When formulating many, including me tend to FOMO, we add untested cool actives. My recommendation is follow the advice above to make a basic lotion you find moisturizing instead of lubricating without actives. Once you are happy with your formulation, add the actives one by one, this way you will know if your actives are causing a problem.

If niacinamide exacerbates your ezcema or cause irritation you want to remove it. Dermatitis usually get worse with continued exposure to irritants.

I would make a thick cream conditioner with benhentrimonium chloride 3% ( max allowed concentration) and some dimethicone and slowly work into wet hair with fingers.

I spent a lot of time researching formulas before starting a new project, and I was happy with the outcome. But lately I am doing knock out experiments because, I suspect some expensive ingredients I am using in my formulas have no impact on the performance of my products.

I agree with lack of enforcement, from what I have noticed some small companies selling in the US do not follow basic INCI labeling, and they also sell their cosmetics at Whole Foods, nobody cares. It is an invitation not to follow the rules…
