We don’t conduct animal testing in the research or development of our cosmetic products. Alongside our parent company, we support efforts to help end to cosmetic animal testing globally.​ to test is a bar is suitable for dry skin, try washing your hands with it and letting your hands air dry, and then waiting to see if they feel moisturized. If they do, it’s suitable for dry skin. To sum things up, I learned a few interesting things from writing this post and asking my dad about the formula change:

If you are into chemistry (if not, we understand, just skip this paragraph), the reason is that electrolytes (you know, the Na+ and Cl- ions) screen the electrostatic repulsion between the head groups of ionic surfactants and thus support the formation of long shaped micelles (instead of spherical ones) that entangle like spaghetti, and viola, a gel is formed. However, too much of it causes the phenomenon called "salting out", and the surfactant solution goes runny again. According to the European Union’s Scientific Committee on Consumer Safety, benzyl alcohol is potentially an allergen. But it’s used pretty commonly as a preservative in the U.S.—I see it on 21 products in the ingredient database, including Cetaphil Moisturizing Lotion, which is typically one of those products that is formulated for people who have sensitive skin. Traditionally, UV-filters are categorized as either chemical or physical. The big difference is supposed to be that chemical agents absorb UV-light while physical agents reflect it like a bunch of mini umbrellas on top of theskin. While this categorization is easy and logicalit turns out it's not true. A recent, 2016 study shows that inorganic sunscreens work mostly by absorption, just like chemical filters, and only a little bit by reflection (they do reflect the light in the visible spectrum, but mostly absorb in the UV spectrum). A real oldie but a goodie. Great natural moisturizer and skin-identical ingredient that plays an important role in skin hydration and general skin health. benzyl alcohol (a preservative), sodium chloride (salt), and paraffin may cause irritation for sensitive skin

The old formula also contained sodium trideceth sulfate and hydrogenated castor oil, which were removed in the new formula. The new version of Aveeno Moisturizing Bar for Dry Skin contains many ingredients that were missing from the old version:

Maybe it’s because it’s formulated for dry/sensitive skin, but it doesn’t seem like Aveeno Moisturizing Bar for Dry Skin is strong enough to remove physical sunscreen by itself—you’ll need to rub your skin pretty vigorously if you want to remove any lotion or sunscreen that contains waxes or oils. This makes it somewhat of an ineffective body soap for people who tend to use those types of products. Since I initially bought this soap with hopes that it could replace my travel-size face soap, but it ended up irritating my facial skin, I probably won’t be repurchasing this soap. Takeaways from this post The main concernwith nanoparticles is that they are so tiny that they are absorbedinto the skin more than we want them (ideally sunscreen should remain on the surface of the skin). Once absorbed they might form unwanted complexes with proteins and they might promote the formation of evil free radicals. But do not panic, these are concerns under investigation. A 2009 review article about the safety of nanoparticles summarizes this, "to date, in-vivo and in-vitro studies have not demonstrated percutaneous penetration of nanosized particles in titanium dioxide and zinc oxide sunscreens". The English translation is, so far it looks like sunscreenswith nanoparticlesdo stay on the surface of the skin where they should be. The other potential skin irritants they should avoided or replaced is paraffin and/or sodium chloride, none of the other new ingredients should not cause irritation for skin.The disadvantage of Titanium Dioxide is that it's not cosmetically elegant, meaning it's a white, "unspreadable" mess. Sunscreens containing Titanium Dioxideare often hard to spread on the skin and they leave a disturbing whitishtint. The cosmetic industry is, of course, really trying to solve this problemand the best solution so far is using nanoparticles. The itsy-bitsy Nano-sized particles improveboth spreadability and reduce the whitish tint a lot, but unfortunately, it also introduces new health concerns. Dear Emily, it may be from Benzyl Alcohol, it’s on EU Allergens. I think they use it as a preservative, they should replace it. Dear Emily, Sodium Cocoyl Isethionate is one of the mildest soap surfactant available for making soap, shampoo, body wash or other cleansing applications.

Titanium Dioxide is one of the two members of the elite sunscreen group called physical sunscreens (or inorganic sunscreens if you’re a science geek and want to be precise). I like that it is fragrance-free and that it contains oat flour, which is supposed to be soothing for eczema. It also foams up pretty decently, but isn’t overly foamy (which can be drying). It’s fragrance-free in the sense that it doesn’t contain any added fragrances, but it’s not fragrance-free in the sense that it doesn’t have any odor at all. It has an odor that some people might fine unappealing; I don’t find it that horrible, since I would much rather smell the natural odor of the functional ingredients in a soap than have to put up with a scent that’s based on floral or overly synthetic fragrances. Galactoarabinan is a natural polysaccharide (a bigcarbohydrate molecule) that comes from theLarch trees.According to the manufacturer it can do all kinds of good in a formula: sodium cocoyl isethionate, avena sativa (oat) kernel flour, hydrogenated vegetable oil, cetyl alcohol, stearic acid, water, disodium lauryl sulfosuccinate, glycerin, paraffin, cocamidopropyl hydroxysultaine, sodium isethionate, benzyl alcohol, galactoarabinan, sodium chloride, propylene glycol, titanium dioxideThis Nourishing Oat Formula contains rich skin conditioners to moisturize dry skin while gently cleansing.
