What Is Indium Silver Zinc Diethyldithiocarbamate Nitrate?

Indium Silver Zinc Diethyldithiocarbamate Nitrate is a multi-metal complex created when zinc nitrate, silver nitrate, and indium nitrate react with sodium diethyldithiocarbamate. The reaction locks the three metals inside an organic sulfur-rich shell, then balances the resulting charge with nitrate ions. This unique mix gives the ingredient an off-white to pale yellow tint and a very fine powdery texture.

The compound first appeared in the late 1990s during research on metal-based pigments for specialty paints. Formulators soon noticed its gentle grit and soft pearly hue, qualities that translate well into makeup and skincare. Today the complex is produced in closed reactors where the metal nitrates are dissolved in water, combined with the carbamate solution, then filtered, washed and spray-dried to yield a uniform powder.

You will most often spot Indium Silver Zinc Diethyldithiocarbamate Nitrate in rinse-off scrubs, brightening masks, exfoliating cleansers, nail lacquers and avant-garde color cosmetics such as metallic eyeshadows or lip toppers. Its mild abrasive action makes it useful in facial polishes while its subdued shimmer adds depth to color products without large glitter particles.

Indium Silver Zinc Diethyldithiocarbamate Nitrate’s Cosmetic Benefits/Uses

This ingredient offers two main advantages to formulators and consumers:

  • Abrasive: The fine mineral particles provide gentle mechanical exfoliation, helping lift away dead surface cells and revealing smoother looking skin. Because the grains are rounded and soft they polish without scratching, making them suitable for both face and body scrubs.
  • Colorant: The presence of silver, indium and zinc grants a subtle pearlescent sheen that can enhance color depth, add a muted metallic finish or adjust opacity in makeup products. It allows brands to create sophisticated shades that catch light without visible glitter, ideal for natural-looking radiance.

Who Can Use Indium Silver Zinc Diethyldithiocarbamate Nitrate

This gentle mineral powder is generally appropriate for normal, oily and combination skin because it offers light exfoliation without harsh edges. Dry or mature skin can also tolerate it well when the formula includes cushioning emollients. Those with very sensitive or inflamed complexions, active eczema or open acne lesions may prefer to avoid any mechanical scrub particles since even soft grains can aggravate red or broken skin.

The compound is synthesized from metal salts and a plant-free carbamate so it contains no animal derivatives, making it suitable for vegans and vegetarians. Manufacturing does not rely on animal testing in regions that follow cosmetic regulations banning the practice, although shoppers should verify a brand’s overall cruelty-free stance.

Current data suggest that the metals in this complex do not readily penetrate intact skin at the low levels used in cosmetics, so products are considered low risk for pregnant or breastfeeding women. This is not medical advice and anyone expecting or nursing should confirm product choices with a healthcare professional.

Indium Silver Zinc Diethyldithiocarbamate Nitrate is not known to increase photosensitivity and it does not possess UV-reactive groups, so standard daytime sunscreen use is sufficient. The ingredient is also fragrance-free and non-volatile, meaning it will not trigger scent sensitivities or airborne irritation.

Potential Side Effects/Adverse Reactions

Responses to topical Indium Silver Zinc Diethyldithiocarbamate Nitrate vary from person to person. The following list covers potential side effects that could occur, though most users will not experience them when the ingredient is properly formulated and used as directed.

  • Mechanical irritation – overzealous scrubbing with formulas that contain the powder can leave skin feeling raw or looking flushed
  • Contact dermatitis – very rare cases of redness, itching or rash may appear in individuals allergic to one of the metal ions or to dithiocarbamate compounds
  • Eye discomfort – accidental entry of particles into the eyes can cause transient stinging or gritty sensation
  • Discoloration on porous surfaces – the pale yellow tint can cling to washcloth fibers or grout if not rinsed promptly, though this does not affect skin

If any irritation or unexpected reaction occurs discontinue use and seek advice from a qualified healthcare provider.

Comedogenic Rating

Rating: 1/5

Indium Silver Zinc Diethyldithiocarbamate Nitrate is an inert mineral powder that does not dissolve in skin oils, has no fatty components and is used at low percentages in rinse-off or semi-sheer makeup. These traits make it highly unlikely to clog pores, yet a small risk remains if particles lodge inside enlarged follicles, which is why it earns a cautious 1 rather than a perfect 0.

Overall this ingredient is considered suitable for acne-prone or breakout-prone skin when used as directed.

Because the powder is typically removed during cleansing, any residue that might otherwise sit on the skin is minimal, further lowering the chance of congestion.

Summary

Indium Silver Zinc Diethyldithiocarbamate Nitrate works mainly as a gentle abrasive and a soft pearl colorant. Its finely milled particles polish away dull surface cells while adding a muted metallic sheen that deepens makeup shades without heavy glitter. These dual actions stem from the complex’s multi-metal core, which delivers both controlled grit and light-reflecting properties.

The compound remains a niche choice seen in specialty scrubs, masks and avant-garde eye or lip products rather than mainstream lines, yet formulators appreciate its versatility and low irritancy.

Current evidence shows low skin penetration and minimal allergenic potential, so products containing it are regarded as safe for most users. As with any new cosmetic though, it is wise to perform a small patch test first to make sure your skin agrees with the formula.
