Sodium Lauryl Sulphate (SLS) in skincare products

A study in ScienceDaily has proven that SLS when used on the skin thins this protective barrier, making the skin more susceptible to irritation by chemicals.

SLS is a detergent used to mix oils into water-based moisturisation creams to give a nice creamy texture. It's also used widely in shower gels, shampoos and other cosmetics.

One more reason to read the ingredient lists carefully before purchasing and using simple homemade remedies as far as possible.

  6. I use SLS free face washes but its very difficult to find other products that are SLS-free. Is there a solution?

  7. Hi,
    Have been reading most of your posts and love most of them. However, sometimes the information you give is not scientifically correct. SLS is not the demon that it is made out to be. Its the mildest surfactant and therefore its used in facewashes and shampoos. Its primary job is to stick to dirt and grime during a body wash or hair wash and remove it. There is a bit of chemistry to this action which i don't want to go into.Those interested can go to Pubmed and type SLS. It'll throw all kinds of studies done. At worst it causes drying due its stripping action however it gets washed off and therefore remains for very little time in contact with skin.

  8. As far as the article goes, it tests a particular formulation- a BP cream which they concur contains SLS.Now when a cream is kept on for hours its bound to show an effect on the skin since SLS dries the skin.And again the abstract doesn't mention other ingredients of the cream.
    However in facewashes,shampoos and bodywashes there is no persistent contact and SLS is too big a molecule to cross skin barrier.

  9. @Anamika: Yup :).. I think that is because there is no regulating body that tests these products for safety.

    @BeautyDiva: Thks :)

    @IMW: Yea, I think these soaps also leave behind residue.

    @Shopping in B: What to do? - Read ingredient lists carefully & opt for products that don't contain this - there are some brands like Lush. I wld also say use natural home made products for the face, they are better in the long run.

    @M.275: There are brands that SLS free, not all creams contain SLS.

    @Zee Bee: Thanks for reading :)

    I have in the above post, literally quoted the study - that SLS in products will cause the skin barrier to weaken. While SLS may not be the demon it is made out to be, it is certainly no angel also. For people with already dry skin like mines or sensitive skin - even a mild, stripping action can cause damage - and consider this, we use this every single day in multiple products - in our soaps, body wash, gels, shampoos, creams & lotions for mattifying effect. So its not just once a day - only one product. This thing is present in multiple products - many of which we use several times.

    However in the end, it is our skin, our responsibilty & our choice. I would choose SLS free products.

    @Simran: Thks :)

  10. Yep its personal choice. However, do SLS free products mention what surfactants they are using to clean the skin? i don't know. I suspect its just a marketing gimmick.The detergent /surfactant family contains ammonium laureth/lauryl sulphates which is again used widely.

  11. And then again quoting one study is never enough to make any assertion. its always a best practice to investigate and go through 20=30 studies about any molecule or ingredient before making a comment because usually after reading a large number of reliable studies can one come to any conclusion.there are people out there who are listening /believing you implicitly.

Reetha, Amla & Shikakai Home Made Shampoo - Weekend Experiment

Good Morning Lovelies, I hope your weekend was fun. Mines was, well, ho-hum, but anyways, we are not talking about that here (let’s save that cribbing for twitter).
I have been suffering from quite a bit of hair fall since some time. I have tried changing products to using intensive conditioning and the works. It stops the hair fall for while, but then it rears its ugly head again.
So on lark, & for lack of better things to do, my best friend & I decided to make some Reetha – Amla – Shikakai shampoo at home. This century old ayurvedic herbal concoction is reputed to not only strengthen hair, but also darken it and stop hair fall.
I got the 3 biggies from a local kirana store. All 3 are priced at 15 Rs for 100gms.

How to: Soak 5 pieces of Shikakai, 4 balls of Reetha  (Soapnut) & handful of Amla (Indian Gooseberry)  in about 500 ml of water overnight. In the morning, heat the mixture on gas till it just starts to boil. Let it cool, when lukewarm mash all the amla, reetha and…

Skin Care Myth: Sunscreen will stop you from Tanning

Image via Wikipedia I know I did a recent article on skin care myths (read it here), but I don't know how I forgot to mention this particular myth. In any case I think this warranted a post on its own.

Myth: If I use a suncreen regularly and religiously, I will not tan. 

Fact: This is a very simplistic statement. But before I bust this myth, kindly bear through a science lecture. This is to bring all readers of all backgrounds on the same knowledge level.



Lets define sunscreen (from Wikipedia):Sunscreen (also commonly known as sunblock or sun cream) is a lotion, spray, gel or other topical product that absorbs or reflects "some" of the sun's ultraviolet (UV) radiation on the skin exposed to sunlight and thus helps protect against sunburn. Sunscreen helps protect only against direct DNA damage as it cannot dissipate UV as harmless heat.

The SPF of a sunscreen is a laboratory measure of the effectiveness of sunscreen — the higher the SPF, the more protection a sunscreen …

I made "Washed Ghee" at home and it turned out great!

Yesterday I posted about the importance of fat in our diet. While doing research for the same I came across the recipe for "Washed Ghee" or Shata Dhaut Ghrita (100 times washed ghee).

After I read about this miracle at home cream, it was inevitable that I would try to create this cream myself. All I needed apparently was some cow ghee & water.

So I made it last evening. And here is how it went.


For those readers who haven't read the earlier post: Hundred times washed ghee is prepared from organic cow milk ghee by washing it in purified water, repeatedly, 100 times in a copper vessel, using a specific prescribed method while chanting some mantras

This procedure transforms the ghee into a soft, cooling, nourishing, silky unguent that is used as a traditional moisturizer and anti wrinkle skin cream. It produces radiant and glowing skin, especially for people with easily inflamed skin. It can be used as a daily face and body moisturizer or for facial massage. Apply it for…
