Cocoyl diethanolamine is a chemical derived from the reaction of coconut oil and diethanolamine.

According to the ratio of the reaction molar amount of coconut oil and diethanolamine, it can be divided into 1:1, 1:1.5, 1:2 and other models.

Diethanolamine is a possible carcinogen without obvious evidence, but it has obvious carcinogenic evidence for some animals.

Diethanolamine reacts with an N-nitrosating agent to form a carcinogen.

Cocoyl diethanolamine containing diethanolamine should be used as much as possible.

Not recommended for use in baby products.

In personal care products, the content of diethanolamine should not exceed 5%.

Coconut diethanolamide Usage

1:1 type is mainly used in liquid soap, baby shampoo, bath foam, cosmetics, etc.

1:1.5 type is mainly used in dish washing detergent, liquid soap, shampoo, bath foam, and liquid detergent, etc.

1:2 type is mainly used in textile printing and dyeing auxiliary, metal processing, tertiary oil recovery, etc.


As a detergent, it is widely used in industrial cleaning, household washing, textile, chemical fiber, leather, personal care products and other fields.

Used as a foaming agent and foam stabilizer.

Used as a rust inhibitor.

Used as an emulsion stabilizer.

Used as a thickener. Especially suitable for anionic surfactant systems.

The guaiac blue oil hydrocarbon has anti-allergic and anti-inflammatory effects. Used for radiant heat burns, cracking, frostbite and promoting wound healing.

Guaiazulene Usage

Guaiazulene has anti-inflammatory effects and promotes the regeneration of tissue granules. It can promote burns, burn wounds, and prevent heat, radiation and chapping.

Guaiazulene is a CTFA-approved cosmetic auxiliaries that can relieve skin irritations and allergic reactions to other substances. It is a common topical anti-allergic agent and has significant anti-inflammatory properties. Used in sunscreen products to prevent or treat sunlight burns. Can be antibacterial, oral hygiene products added 0.1% can inhibit microbial growth. Guaiac wood can also be used as a cosmetic pigment.

Due to its wide absorption range, its effective absorption peak is 350-400 nm, and it has been absorbed to about 420 nm. Its absorption peak is longer than that of conventional initiators. After irradiation, two free radicals of benzoyl and phosphoryl groups can be formed. It can initiate polymerization, so it has fast photocuring speed. It also has photobleaching effect. It is suitable for deep film thickening and yellowing of coating. It has low volatilization and is suitable for water-based. Used in white systems, it can be used in UV-curable coatings, printing inks, UV-curable adhesives, optical fiber coatings, photoresists, photopolymer plates, stereolithography resins, composite materials, dental fillers, etc.


Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide Usage

Photoinitiators, mainly used for screen printing inks, lithographic printing inks, flexo printing inks, wood coatings.

A general dye is a colored conjugated system which has the property of dyeing fibers or coloring a resin, and the conjugated system of a heat-sensitive, pressure-sensitive dye is interrupted, itself is colorless, but it has a function with a color developer. And the performance of hair color. Under acidic conditions, the lactone ring is cleaved to form a 醌-type large π bond colored group, which emits a bright, high-concentration blue-violet color with maximum reflected light absorption at 609.8 nm. Irritating.


Crystal violet lactone Usage

Is an important functional dye for the production of pressure sensitive materials.

Toluhydroquinone Application

Used as a medicine, dye and pigment intermediates, antioxidant, is also a kind of new type inhibitor. 


Mainly used in pigments, dyes, pharmaceutical intermediates.

Used as medicine, dye, pigment intermediate, antioxidant, also a new type of polymerization inhibitor.

Antioxidants, in the presence of free radicals, can react with free radical additions to consume free radicals.


A new type of polymerization inhibitor, methylhydroquinone is a high-efficiency unsaturated resin polymerization inhibitor. Generally, the addition of two parts per million resin can achieve a good polymerization inhibition effect in production and storage, and anti-resin hardening after polymerization. The stability of the product is more than half a year; the solubility of methylhydroquinone is good, and it has no pollution to its own product. It is not affected by temperature and environment. It only needs one product to ensure the quality of the resin. Methylhydroquinone is not affected by temperature, and it reacts rapidly with free radicals to achieve rapid inhibition. However, the thermal decomposition of t-butyl catechol loses the inhibition effect and even affects the color of the resin; it is not affected by the environment, in the aerobic Or in an oxygen-free container, it can act as a polymerization inhibitor, while hydroquinone does not work in an oxygen-deficient container. The resin produced by using methylhydroquinone does not affect the final curing speed of the resin under the action of the initiating system; methylhydroquinone is more excellent in the high-temperature curing type pultrusion and pressure-sensitive resin. The effect is the first choice for a new generation of unsaturated resin polymerization inhibitors.
