How are Lego bricks made? A surfactant, when present in small amounts, reduces surface tension of a liquid (reduces the work needed to create the foam) or increases its colloidal stability by inhibiting coalescence of bubbles. Foaming hand soap dispensers are created to release less soap than regular soap dispensers do. Syndet surfactants are derived from oils, fats, or petroleum products that are processed in a wide range of chemical processes other than traditional saponification.

Bar soaps break this. So, if liquid hand soap has been such a big improvement, what explains the sudden popularity of foaming hand soap and how effective is it? Foam is a side effect of using a tensio-active agents (though some tensio-active agents are engineered to produce as little foam as possible, e.g. (Above are sample images from a controlled study to determine the number of bacteria from contaminated hands transferred to an agar surface before (A and C) and after (B and D) hand washing with bacteria contaminated soap from American Society for Microbiology study called Bacterial Hand Contamination and Transfer after Use of Contaminated Bulk-Soap-Refillable Dispensers). It contains niacinamide that makes this bar soap suitable for acne and oily skin types.

We know that there is a possibility of microbial growth in liquid soap and if contaminated, it could spread an infectious disease or cause microbial rancidity in our products.

Companies use SLS to create a rich lather, and for its intense cleaning action.

Generally, any material that affects the interfacial surface tension can be considered a surfactant, but practically, surfactants may act as wetting agents, emulsifiers, foaming agents, and dispersants. People with allergies or sensitive skin do better with soaps that contain fewer ingredientsand the ones they do have are more natural. Whats a Syndet bar, whats a Combo? During the bottling process, it is imperative to use a clean and sterile packaging environment, in addition to the use of sterilized bottling materials, in order to prevent the risk of microbial product contamination.
