Laundry Detergent Ingredients and How They Work

May 07, 2021·Laundry detergents have come a long way since the first bar soaps made from animal fat and lye were offered for sale in the 1700s. The introduction of synthetic detergents to the marketplace in the 1950s offered homemakers more options for fabric care. But it was the 1970s that brought the most significant innovation in the laundry, the addition of enzymes that "attack" specific types of stains.

Jul 14, 2013·General purpose detergents are suitable for all washable fabrics. Powders are especially effective in lifting out clay and ground-in dirt. Liquids work best on oily soils and for pretreating soils and stains. Light duty detergents are used for hand or machine washing lightly soiled items and delicate fabrics. Cake or detergent bars are used.

Synthetic Detergent - an overview | ScienceDirect Topics

Synthetic Detergent. Synthetic detergents are composed by surfactants that mobilize organic particles in water by forming micelles, builders that facilitate the action of the surfactant by sequestering Ca2+ and Mg2+, and different softeners and fragrances.

In non-ionic detergents, this behavior has been applied in the phase separation and purification of membrane proteins. 2. Detergent Types and Selection. When selecting a detergent, the first consideration is usually the form of the hydrophilic group. Based on their structure, detergents can be broadly classified as: 3. Ionic; Zwitterionic; Non ...

soap and detergent | Chemistry, Uses, Properties, & Facts ...

In order to perform as detergents (surface-active agents), soaps and detergents must have certain chemical structures: their molecules must contain a hydrophobic (water-insoluble) part, such as a fatty acid or a rather long chain carbon group, such as fatty alcohols or alkylbenzene. The molecule must also contain a hydrophilic (water-soluble) group, such as ―COONa, or a sulfo group, such as ...

Glycerine: overview

The origin, chemical structure, and utility of glycerine have been known for little more than two centuries. Glycerine was accidentally discovered in 1779 by K. W. Scheele, the Swedish chemist, while he was heating a mixture of olive oil and litharge (lead monoxide). Scheele called glycerine the "sweet principle of fat."2

Today, the process of making soap most commonly involves reacting an organic acid with an alkaline chemical like potassium hydroxide or sodium hydroxide.Industrially, the caustic soda base used most often is sodium hydroxide, which is also called lye. The main difference between potassium and sodium soaps is consistency — usually, potassium makes a softer, more water-soluble soap than sodium.

Different Types of Detergent | Cleancult

Conventional Detergent: Conventional Laundry detergent, like any other product, can contain toxic chemicals and even carcinogens. The conventional detergents use chemicals to bring fragrance, the cleaning agents to make the laundry cleaner, the stabilizers to stabilize their shelf life, and bleach, brighteners and phosphates to make the detergents more effective in hard water.

THE SCIENCE OF SOAPS AND DETERGENTS

Soap works by breaking up the oil into smaller drops, so it can mix with the water. The principle of soap works because soap is made up of molecules with two very different ends. One is hydrophilic, and it is this end of the soap molecule that loves water. This is the "salt" end of the soap…

detergents; this soap is a completely vegetable (or plant) based soap. Also, in the commercial saponification reaction, the glycerol (or glycerin) that is produced is removed (it is often worth more to the company than the soap itself), and other (less expensive) materials are added to the soap to provide the qualities of glycerol.

What's The Difference Between Soap and Detergent | Cleancult

Soap vs. Detergent. As mentioned before, there is a chemical difference between the formulas of soap and the formulas of detergents. The advantage of (either non-toxic or conventional, mainstream) laundry detergents over soap is that the former are specifically formulated to work in washing machine environments, some even are formulated to work in special HE Washing Machine.

Surfactants - Essential Chemical Industry

Soaps are anionic detergents: Cationic surfactants. With these surfactants, the hydrophilic head is positively charged. Although they are produced in much smaller quantities than the anionics, there are several types, each used for a specific purpose. (a) Mono alkyl quaternary systems. The simplest quaternary system is the ammonium ion:
