Fermentation is not only a current trend for food, but also an important process in order to obtain a small miracle active ingredient: we are talking about sodium lactate. We say what it can do and whether it is harmful or good for the skin.
What are Sodium Lactate or Sodium Lactate
Sodium lactate INCI: Sodium Lactate is the salt of lactic acid. In cosmetics, the ingredient maintains moisture, stabilizes the pH value and helps remove dead horny cells..
Sodium lactate is vegan
Although it is the salt of lactic acid, sodium lactate is quite a herbal product. Because the chemist Carl Wilhelm Scheele was able to detect lactic acid in milk for the first time in 1780, the name, which is now very misleading, came about.
Like other lactates, the ingredient is obtained through fermentation: microbial or enzymatic processes convert a source of sugar, such as corn or beets, into acid. This lactic acid is then neutralized. The sodium lactate is ready..
Food manufacturers use lactic acid salt, for example, to regulate acidity, retain moisture, melt cheese or give food a firm consistency. Because it is harmless in food, it can be used as an additive E323 without hesitation.
So now you know what that E323 means. But what about in cosmetics
What is the function of sodium lactate in cosmetics
In cosmetics you will come across sodium lactate again and again, but you will not find it with this name among the ingredients:
As an INCI name, the sodium salt of lactic acid has the name Sodium Lactate and is accordingly also pronounced in English.
The advantage of Sodium Lactate in cosmetics is: It supports theNatural moisturizing factor, in short: NMF.
It does this via two important properties:
-
Sodium Lactate retains moisture
The NMF is made up of various substances. These include proteins, urea, lactic acid, sugar and inorganic ions such as potassium and magnesium ions, but also our sodium lactate.
A comparison betweendry winter skin and normally hydrated summer skin has shown that sodium lactate creates a connection: the content of this substance was lower in dry skin. If the skin lacks sodium lactate, it tends to become dry.
This is because: Sodium lactate is able to bind moisture. The active ingredient increases the water content of the skin and ensures that it remains soft and less wrinkled.
So Sodium Lactate is an important ingredient in anti-aging care.
-
Sodium lactate stabilizes the pH value
Care products for the skin should preferably have a pH value between 5 and 5.5 so that they do not attack the skin's own protective acid layer. The acid mantle is closely related to the NMF and ensures that the skin does not lose moisture and prevent itbad bacteria andfree radicals remains protected.
In care products, sodium lactate, together with lactic acid, regulates the pH value. This allows cosmetics to care for the skin instead of attacking it.
Bonus: Sodium Lactate has a keratolytic effect
Some substances in cosmetic products help the skin to loosen and remove dead skin cells from the horny layer. The property of these active ingredients is keratolytic. Sodium Lactate possesses such as for exampleurea also this property and has a correspondingly scaling effect.
Good cosmetics need the ingredient sodium lactate
We say yes.
Sodium Lactate is not only an endogenous and absolutely harmless substance, it significantly supports the NMF and helps to hydrate the skin.
This makes sodium lactate an important element for good cosmetics and also perfectly suitable for certified natural cosmetics.
Cosmetics manufacturers can easily use it in products that stay on the skin as leave-on products or rinse-off products. You can find sodium lactate in lotions, creams, shampoos and all kinds of care products. And also with the products from sober.er.
We use sodium sober products
With our care products for demanding skin, you will find sodium lactate where good moisturizing care has a positive effect on the anti-aging process.
The hydrating and pH regulating properties of sodium lactate aid in its effectivenessHydra Defense Cream, at theTimeshift serum and also atAfter Shave Repair Fluid.
Let only the good things get to your skin and #staysober
