Abstract:

Dishwashing liquid is a biodegradable, designed to remove grease and oils while remaining gentle on the

hands. It provides long-lasting suds while soaking dishes clean and rinses freely without streaking or

spotting. The experiment aims to prepare a dishwashing liquid and to compare the ability and capacity

of a experimental product to the reference product. It was done by mixing the LABS, fragrance, FD&C

Yellow, Tea, Oil, colorant ,Sodium Lauryl Sulfate and Alcohol Sulfate into 1.2 liter of water. The texture is

homogeneous and became immiscible. The addition of sodium chloride will increase the viscosity of the

mixture. The preciseness and effectiveness of the experimental product was quite similar to the

commercial product.

Introduction:

Dishwashing liquid also known as dishwashing soap and dish soap, is adetergent used to assist

indishwashing. It is usually a highly-foaming mixture ofsurfactants with low skin irritation, and is

primarily used for hand washing of glasses,plates,cutlery, andcooking utensils in a sink or bowl. The

reducedsurface tension of dishwashing water, and increasing solubility of modern surfactant mixtures,

allows the water to run off the dishes in a dish rack very quickly. However, most people also rinse the

dishes with pure water to make sure to get rid of any soap residue that could affect the taste of the

food. A dilute combination of dishwashing liquid with water can be used to producesoap bubbles.It has

also been administered orally as a substitute forsoap as a form ofcorporal punishment. This is often

colloquially referred to aswashing the mouth out with soap or another similar phrase. However, this use

carries health risks and has declined substantially in recent decades. Dishwashing liquid has also been

used as a stain cleaner.Dishwashing liquid has also been used to treatbirds affected byoil spills.It can

also be used to mix mortar when there is no Plasticizer available on the building sites.

Theoretical Background:

In the early days of their discovery, detergents were made from alkyl napthalene sulphonates, which are

still used as wetting agents of 2010 practices. Straight-chain detergents were then produced by the

sulphonation of straight-chair alcohols. These substances were later used in shampoos. Improved

detergents were more highly dissolvable in water. By 1950, the majority of detergents used a PT

benzyne formula. In 1965, companies had to rethink the formula used because sulfates and phosphate

chemicals are harmful to the environment. By the 1990s, products became available in liquid and gel

formulas. Companies added different perfumes and dyes to change the color and scent of dishwashing

detergent. Since 2000, there has been a rise of products containing low phosphates and no phosphates.

This came about because of the demand and necessity for companies to produce detergents that are

powerful but not harmful to the environment.
