Description

A kind of dish detergent containing N-fatty acyl glutamate

technical field

The invention relates to a dish detergent containing N-fatty acyl glutamate, which belongs to the technical field of daily chemicals.

Background technique

Dishwashing detergent is a kind of light-duty liquid detergent. In addition to cleaning tableware, this kind of detergent can also wash fruits and vegetables. The hand-washing dishwashing agents currently used in the market are all multi-component products of anionic and nonionic surfactants. It uses a rag, wire or scouring pad to pick up detergent to remove dirt from the surface of the dish. Since it is mainly made of petrochemical by-products, the skin will be irritated if it is in contact with it for a long time. In daily use, when washing tableware with detergent, it needs to be rinsed repeatedly, and there may be a very small amount of chemical substances remaining, which may also cause damage to people over time.

Similarly, due to the impact of pesticide residues in vegetables and fruits on human health has been widely concerned, food poisoning incidents caused by eating vegetables and fruits containing pesticide residues also occur from time to time. People also try to wash vegetables and fruits with ordinary detergents. Although some residual pesticides can be washed away with ordinary detergents, it does not work for the removal of fruit wax used for fresh-keeping on the surface of vegetables and fruits, and the residue of detergent itself will also affect adverse effects on human health. In addition, the washing and rinsing liquid is discharged into the sewer, which has poor biodegradability and will also cause a certain degree of pollution to the environment.

Therefore, there is an urgent need in the market for a kind of tableware that can be washed, effectively removes fruit and vegetable residual pesticides, and has no damage to human health and a multipurpose detergent.

Contents of the invention

The object of the present invention is to provide a kind of N-fatty acyl glutamate dishwashing detergent which has no harm to the skin, mildness, little irritation, strong degreasing power and good biodegradability.

The technical scheme of the present invention: a dishwashing detergent containing N-fatty acyl glutamate, which is composed of the following raw materials in weight percent: N-fatty acyl glutamate 0.1% to 10%, anionic surfactant 1 %～25%, nonionic surfactant 1%～25%, amphoteric surfactant 0～4%, polyol humectant 0～5%, electrolyte 0～5%, pH regulator 0～1%, Kaisong 0 to 0.1%, essence 0 to 0.3%, and water to make up 100%. Its manufacturing process is: under stirring, N-fatty acyl glutamate, anionic surfactant, nonionic surfactant, zwitterionic surfactant, polyol humectant, water, pH regulator, at room temperature or heating After mixing under the same conditions, add electrolyte and mix evenly under stirring at the same temperature. After cooling, add essence and preservative Kaisong and mix evenly to obtain the product. the

N-fatty acyl glutamate as mentioned above is an amino acid type anionic surfactant. There are the following forms:

Wherein the acyl group is an acyl group derived from a _C8-22 saturated or unsaturated fatty acid, for example, it may be an acyl group derived from a mixture of fatty acids of a single composition such as lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, behenic acid, etc. , In addition, it may be a refined product from naturally obtained mixed fatty acids such as palm oil fatty acid, coconut oil fatty acid, sunflower oil fatty acid, soybean oil fatty acid, tallow fatty acid, hardened tallow fatty acid, or an acyl group derived from a fatty acid mixture obtained by synthesis, N- As the fatty acyl glutamate, metal salts such as sodium and potassium, and organic salts such as triethanolamine are generally preferred.
