Sodium Stearoyl Lactylate (SSL) is another fantastic emulsifier that helps stabilize oil-in-water formulations such as a lotion.  SSL is a natural, food-grade emulsifier derived from the sodium salt of lactic acid.  Because of the sodium makeup of SSL, this additive is able to penetrate the top dead layers of skin for enhanced skin moisturizing capabilities.  SSL is part of an emulsifying system and needs to be used in conjunction with another emulsifier in order to stabilize the emulsion.  I use SSL in several of my goat-milk lotions, as well as my Simply Radiant Face Cream and just love how it feels on my skin!  EcoCert Certified.

Sodium lactate is a natural humectant, which helps to retain moisture.  It is the *sodium salt of natural Lactic Acid, produced through the fermentation of sugar, an AHA that occurs everywhere in nature and is a natural moisturizing factor constituent of skin. Sodium Lactate is a superior moisturizer, increasing the moisture content of skin by up to 90%. When compared to other commonly used moisturizers, it’s water holding capacity is second only to Sodium Hyaluronate (Hyaluronic Acid).

When used in soap, sodium lactate also adds a firmness to the soap while adding its humectant properties to the soap as it is commonly known that even regular table salt gives soap extra firmness to an otherwise softer bar.  Sodium lactate is a lovely natural additive to soaps and lotions and often overlooked in lotion making.
