Belassi: Kao is also some of the largest cosmetic companies of the world. They own several skincare and haircare brands, from popular to very luxury ones, specially in Japan.

MarkBroussard: it´s often done by postal services, during transport…
With globalization, a consumer can buy from Internet a product that is stored under 15°C in another country and receive it in a place a country above 40°C… -
“Elegant skin feel” - not so much. Who decides? How do you assign numerical values to this? Without values, computerization/automation is useless. For much the same reason, DOE/Six Sigma techniques don’t work well for cosmetics.”
Maybe this part wouldn’t the hardest one. Shiseido for instance is trying to put this in numbers:“Research regarding cosmetic affective evaluation using electroencephalogram analysisFor affective impression related evaluation such as texture of cosmetics, highly-trained specialists are in charge. However, in order to further comprehend how customers actually feel in an objective manner, we have been conducting the joint research with Professor Masahiro Nakagawa, Nagaoka University of Technology. It does not utilize the electroencephalogram in the low frequency region (α wave band, θ wave band, etc.), which is utilized in the conventional electroencephalogram analysis, but it is the technique to detect the customers’ predominant impression when using cosmetics based on fractal dimension analysis of electroencephalogram in the middle frequency region before the customers become aware of the sensitivity.To be specific, we ask the customer to picture sensitivity words such as “refreshed”, “sticky” and “moist” and record the electroencephalogram at that moment. After this, when the same customer actually uses the cosmetic product, we take her electroencephalogram and analyze it by sensitivity word pattern, enabling us to comprehend how much the customer actually experience those impressions.”

Maybe in the future a system could help to formulate a non-stick, smooth formula (elegant…) without to have to try it on many subjects.

“Polyquaternium-10 0.25% - This will have a conditioning effect but can also build up on hair. If you use it for a few weeks your hair will start to feel dull and coated.”
So, do you think it makes sense when women often change the shampoo because they say the hair “gets used” to the shampoo? Many women have several shampoo brands to prevent the hair “gets used”… -
If you add silicones your SPF can be boosted a lot.
And I wouldn´t use AVO with OMC - this combination can be very photounstable even in presence of AVO stabilizers like OCT. -
You can choose another country to test, it could be less expensive. If they use the FDA methodology, I guess you don t need to test in the US.

TKS. I asked because I am seeing many lists similar to this product: http://www.drugstore.com/avene-cleanance-mask/qxp410713?catid=182937

Have you tried a bit of alcohol?

You could try to interview some researcher from Procter & Gamble. Procter & Gamble is expert in “fermented cosmetics”, due SK-II brand (owned by P&G).

It also depends a lot of your surfactant system in your syndet. I’m sure that a sodium lauryl sulfate base syndet could dry out the skin even more than many soapy based cleanser bars.

Some emulsifiers can add skin care benefits as well. The Japanese Nikkol claims that emulsifier can offer anti-inflammatory and moisturizing effects:
I love emulsifiers from Nikkol. But like most Japanese raw materials they are usually very expensive. -
The history of the technology… that’s interesting!

pH 2? Are you sure? Seems to be too low…

I’ve heard sodium hyaluronate is more stable. Hyaluronic acid almost isn’t used. There are a lot of supplies which sell sodium hyaluronate and other hyaluronic acid derivatives.

AmorePacific will transfer the cushion technology to Dior (LVMH) and make a new partnership:

I agree that many ingredients in the formula aren’t necessary and are in a amount much higher than the usual. But 4% of niacinamide +2% glucosamine is a interesting combination:

Do you thunk tranexamic acid (it’s a traditional drug to control hemorrhage when orally administered) could be a problem in cosmetics sold in the US?
Tranexamic acid is trending in cosmetics due some studies showing its topical use could prevent dark spots, improve skin’s barrier function and relief dryness.Here an example of cosmetic with TA: -
Perry: that’s due the fact their study only counts cosmetics. P&G and Unilever are bigger if you also count their food, diaper business etc.

I’ve just got it… If anyone is curious… top 10 in 2014:
1 - L’oréal2 - Unilever3 - Procter & Gamble4 - Estée Lauder5 - Shiseido6 - Beiersdorf7 - Avon8 - Chanel9 - Johnson & Johnson10 - Kao Corporation.Curious note: Korean companies are quickly going to the top 10. AmorePacific already is the 14 (aims to be the 10 already next year and 5 in 2020). LG already is the 20. -
My products contain Tinogard TS or similar. I don’t think TiO2 will work well for that case.

@luiscuevasii Even so… Shaving gels from Gillette, for instance, have a pH between 8.3 and 8.9.
I really wouldn’t expect a relevant foam from stearic acid in a pH around 7. -
pH 6.5 - 7.5 can be too low if you want the dense foam from “soapy” stearic acid. Products like that usually have a pH around 8, 9…

Maybe the shape of the particle can make some difference as well:
