Nonivamide, with CAS 2444-46-4, has the English name Capsaicin and the chemical name N-(4-hydroxy-3-methoxybenzyl) nonylamide. The molecular formula of capsaicin is C₁₇H₂₇NO₃, and its molecular weight is 293.4. Nonivamide is a white to off-white crystalline powder with a melting point of 57-59°C, a boiling point of 200-210°C (at 0.05 Torr), a density of 1.037 g/cm³, slightly soluble in water, sensitive to light and heat, and should be stored away from light.
Nonivamide has multiple uses. In the medical field, it can be used for pain relief, anti-inflammation and relieving itching. In the food industry, it can be used as a spicy seasoning and food flavoring additive. In addition, Nonivamide can also be used as a pesticide enhancer, an additive for anti-fouling coatings, and a functional component in daily chemicals, etc. Today, we mainly want to learn about the applications of nonivamide in daily chemical products.
1. Skin care products: Targeted function addition
Firming and shaping products
Some slimming creams and firming gels contain low concentrations of nonivamide. The principle is that it can stimulate the dilation of skin blood vessels, promote local blood circulation, accelerate skin metabolism, and at the same time generate a “warm sensation” through slight nerve stimulation, making users subjectively feel that fat is “burning”. However, this effect only targets the microcirculation under the epidermis and has limited effect on the decomposition of deep fat. It needs to be combined with exercise and diet to assist in body shaping.
Auxiliary ingredients for hair removal products
A few hair removal creams or waxes contain nonivamide. By taking advantage of its mild irritation to hair follicles, it temporarily inhibits the growth rate of hair and reduces skin sensitivity after hair removal (the concentration must be strictly controlled to avoid excessive irritation).
Prevention and repair of chilblains
Low-concentration nonivamide can promote local blood circulation and is used as an auxiliary ingredient in some chilblains to help improve microcirculation in areas such as hands and feet, and relieve problems such as skin stiffness and purpliness caused by cold.
2. Bath and cleaning products: Enhance sensory experience
Functional body wash
Some body washes that focus on “heating up” and “dispelling cold” contain nonivamide. After use, the skin feels warm, making them suitable for autumn and winter seasons or scenarios where quick warming is needed (such as after exercise). However, it should be noted that such products may irritate sensitive skin and should be thoroughly rinsed off after use.
Foot care products
Nonivamide is added to some foot creams and patches to improve blood circulation in the feet, relieve foot coldness and fatigue caused by prolonged sitting and cold, and at the same time help reduce foot odor (by inhibiting the activity of some bacteria).
3. Other daily chemical scenarios: Niche functional applications
Anti-biting paint
Adding a low concentration of nonivamide to pet supplies (such as dog lees and cat scratches) or furniture surface coatings can prevent pets from biting by taking advantage of its pungent smell and taste, and it is safer than chemical insect repellents.
Repellent daily chemical products
Some outdoor mosquito repellents and ant sprays contain nonivamide (usually combined with other repellent ingredients), taking advantage of its irritability to insects to enhance the repellent effect, especially effective against crawling pests such as ants and cockroaches.
Precautions for Use
Irritation risk: nonivamide has a natural irritant effect on the skin and mucous membranes. High concentrations or frequent use may cause redness, burning, itching, and even allergic reactions on the skin. People with sensitive skin, children, and pregnant women should use it with caution.
Strict concentration control: The addition amount of nonivamide in daily chemical products is usually extremely low (generally less than 0.1%), and it needs to be combined with soothing ingredients (such as aloe vera) to neutralize irritation. Regular products will clearly indicate “Use with caution for sensitive skin”.
Avoid contact with special areas: After using products containing nonivamide, avoid contact with mucous membranes such as the eyes, mouth and nose. If contact occurs accidentally, rinse with clean water immediately and seek medical attention promptly.
In conclusion, nonivamide has achieved diverse functional values from daily diets to professional fields, thanks to its “stimulating” properties. It is a natural compound that combines practicality and research value.
