Isothiazolinone allergy, particularly to methylisothiazolinone (MI), is a common cause of allergic contact dermatitis. This preservative is widely used in personal care products, cosmetics, cleaning agents, and industrial products. When exposed to isothiazolinone, sensitive individuals may experience symptoms such as redness, swelling, itching, and fluid-filled blisters. Reactions can occur on various parts of the body, including the face, hands, scalp, and neck, often due to contact with products like shampoos, sunscreens, and wet wipes.

To avoid reactions, it is crucial to read product labels and avoid those containing isothiazolinone or its derivatives, such as methylchloroisothiazolinone. If an allergic reaction occurs, treatment may include topical corticosteroids, emollients, and antihistamines. In severe cases, steroid pills may be necessary.

Isothiazolinone (Isothiazolinone) is a highly effective, broad-spectrum bactericidal preservative with antibacterial, antifungal and anti-algal properties. It is widely used in industrial circulating water, paper making, oil field water injection, cosmetics, paints, cleaning agents and other fields. Its mechanism of action is to inhibit the growth of microorganisms by disrupting the DNA molecules or protein bonds within the microbial cells.Isothiazolinone is effective in a wide pH range, can be naturally degraded to non-toxic substances, and is friendly to the environment.

In textile printing and dyeing industry, HEDP (Hydroxyethylidene Diphosphonic Acid) is mainly used as chelating agent, color-fixing agent and dye dispersant with the following specific applications:

1. Preventing metal ions from interfering: HEDP is able to chelate calcium, magnesium, and other hard water ions in water, avoiding the reaction of these metal ions with dyes, thus ensuring the uniform adsorption of dyes and color fastness.
2. Color fixing treatment: After dyeing and printing, HEDP can be used as a color fixing agent, which reduces the interaction between dyestuffs and metal ions through the formation of stable chelates, enhances dyeing fastness and prevents fading.
3. Dye dispersion and stabilization: HEDP helps to improve the dispersion of dyes, preventing dyes from aggregation and precipitation, so as to ensure the uniformity of colors during the dyeing process.
4. Improvement of dyeing solution stability: By chelating metal ions, HEDP can reduce the formation of precipitation in the dyeing solution, improve the stability of the dyeing solution and reduce the dyeing defects.
5. Cleaning and descaling: Before dyeing, HEDP can be used to clean metal equipment, remove oxides and scale on the surface of the equipment, and prevent metal from polluting the dyeing solution.

The concentration of HEDP used in textile printing and dyeing is generally between 0.5% and 2%, and the specific dosage should be adjusted according to the actual demand.

HEDP (Hydroxyethylidene Diphosphonic Acid) is an organic phosphonic acid compound with the chemical formula C₂H₈O₇P₂ and molecular weight of 206.03. It is a highly efficient scale and corrosion inhibitor, which is able to form stable complexes with calcium, magnesium and other metal ions in water, thus effectively preventing the formation of scale.
HEDP has good chemical stability. HEDP has good chemical stability, in high temperature (up to 250 ℃) and high pH value conditions can still maintain stability, not easy to hydrolyze.
HEDP is widely used in scale and corrosion inhibition treatment in industrial circulating cooling water system, oil field water injection system, low pressure boiler, etc.
It is also used as peroxide stabilizer and color fixer in textile printing and dyeing industry, and as chelating agent in non-cyanide plating.The recommended dosage of HEDP is 1-10 mg/L (as scale inhibitor) or 10-50 mg/L (as corrosion inhibitor). Its solid form is crystalline powder, which is suitable for use in winter and cold regions.
