General Description:

Imidazolidinyl Urea is a widely used preservative and antimicrobial agent in the cosmetic and personal care industry. It is a white, crystalline powder that is water-soluble and functions primarily as a formaldehyde-releasing agent. It is known for its effectiveness in preventing microbial growth, thereby extending the shelf life of products. Imidazolidinyl Urea is commonly found in a variety of formulations, from skin care to hair care products, due to its broad-spectrum preservative properties. It is available for bulk supply, making it a common ingredient in large-scale cosmetic manufacturing.

Uses in the Cosmetics Industry:

Imidazolidinyl Urea is used in:

Skincare products such as creams, lotions, and serums to prevent microbial contamination.
Hair care products, including shampoos and conditioners, to ensure product stability and safety.
Cosmetics and makeup products to preserve the formulation and extend product shelf life.
Body care items like deodorants and body lotions to maintain cleanliness and prevent bacterial growth.
Due to its broad-spectrum preservative action, it is commonly included in products that require long-term storage or that are exposed to repeated use, such as in pump bottles and jars.

Side Effects & Hazards:

While Imidazolidinyl Urea is effective as a preservative, it can cause skin irritation or allergic reactions in some individuals, particularly those with sensitive skin or a history of allergies to formaldehyde-releasing agents. It is important to note that this ingredient slowly releases formaldehyde, a substance known for its potential to cause irritation, sensitization, or even allergic reactions in sensitive individuals. Prolonged exposure to formaldehyde has been linked to certain health concerns, such as skin irritation and respiratory issues, so it is regulated in cosmetic formulations to limit concentrations and ensure safety.

During manufacturing, proper safety precautions, including the use of gloves and goggles, should be taken to avoid direct skin or eye contact with the powder. It is also important to store products containing Imidazolidinyl Urea in sealed containers in a cool, dry, and well-ventilated area to prevent exposure to moisture, which could lead to the release of formaldehyde at higher concentrations.

Safety & Regulatory Considerations:

Imidazolidinyl Urea is regulated by cosmetic safety authorities such as the FDA and EU Cosmetics Regulation, with recommended concentration limits typically around 0.6%. It is essential for manufacturers to ensure that its use complies with local regulations and product safety standards. For sensitive skin formulations, some manufacturers may opt for alternative preservatives to avoid the potential risks associated with formaldehyde-releasing agents.

FAQ (Frequently Asked Questions)

Imidazolidinyl Urea is a preservative used in personal care and cosmetic formulations to prevent the growth of bacteria, yeast, and mold. It is a formaldehyde-releasing compound that helps extend shelf life and maintain product safety, especially in water-based formulations.

CAS Number: 39236-46-9
INCI Name: Imidazolidinyl Urea

Provides broad-spectrum antimicrobial protection

Effective against bacteria, yeast, and molds
Increases the shelf life of water-containing products
Works synergistically with other preservatives
Stable in a wide pH range (typically 3 to 9)

This preservative is commonly used in:


Moisturizers and lotions
Shampoos and conditioners
Liquid soaps and cleansers
Makeup products (foundation, powders)

Yes, it is approved for cosmetic use in many countries, including the US (FDA) and EU, with maximum concentration limits. However, since it is a formaldehyde-releasing agent, its use is restricted in leave-on products in some regions, and it's important to comply with local regulations.

Typically used at 0.3% to 0.6% in cosmetic formulations. The maximum allowed concentration varies by region, and regulatory guidelines must be followed.

While generally well-tolerated, sensitive skin users or those with formaldehyde allergies may experience irritation. For sensitive skin products, alternative preservative systems are often considered.

Imidazolidinyl Urea is a synthetic preservative. It is not considered natural or organic and is typically avoided in clean beauty or natural-certified formulations.
