3-Iodo-2-propynylbutyl carbamate is broad spectrum preservative and dry film fungicide. 
3-Iodo-2-propynylbutyl carbamate is used in interior and exterior paints, wood protective stains, paper coatings, plastic coatings and inks. 
3-Iodo-2-propynylbutyl carbamate exhibits low viscosity, easy pumping and no settling of solids. 
3-Iodo-2-propynylbutyl carbamate offers low freezing point temperature. 
3-Iodo-2-propynylbutyl carbamate possesses very good dry film fungal protection.

Iodopropynyl Butyl Carbamate (IPBC) is a preservative used globally in the paints & coatings, wood preservatives, personal care, and cosmetics industries. 
IPBC is a member of the carbamate family of biocides.
IPBC was invented in the 1970s and has a long history of effective use as an antifungal technology.

IPBC was initially developed for use in the paint & coatings industry as a dry-film preservative to protect interior and exterior coatings from mold, mildew, and fungal growth, while also offering cost performance and sustainability benefits. 
IPBC exhibits efficacy against a broad spectrum of fungal species, typically at very low use levels. 
IPBC today is incorporated into a wide variety of interior and exterior paint formulations around the world.

Use is restricted in some countries due to its toxicity, especially acute inhalation toxicity. 
IPBC is also becoming recognized as a contact allergen.

IPBC is an effective fungicide at very low concentrations in cosmetic and other products, and has shown very low sensitivity in humans tested with this preservative. 
IPBC was approved in 1996 for use up to 0.1% concentrations in topical products and cosmetics. 
However, this preservative is mostly found in cosmetics at about one-eighth that level. 
IPBC Toxicity and Safety Tests show it to be generally safe: When used properly in leave-on skin products, IPBC is extremely safe. 
Previous to being approved for cosmetic use in 1996, extensive safety and toxicity tests were conducted on IPBC and their results were gathered along with earlier studies in a report of the Safety Assessment of IPBC by the Cosmetic Ingredient Review. 
This final report found IPBC to be a non-carcinogen with no genotoxicity and in reproductive and developmental toxicity studies using rats and mice, IPBC had no significant effect on fertility, reproductive performance, or on the incidence of fetal malformation.

The study, "Final Report on the Safety Assessment of Iodopropynyl Butylcarbamate", discusses the results of 32 studies between 1990 and 1994 in 3,582 subjects using skin application of IPBC at relevant concentrations. 
All 32 studies showed no evidence of contact sensitization compared to placebo controls, with the report stating "With each test formulation, a few panelists had erythema, edema, and/or a papular response, but overall, the results were negative." 
In addition, the study mentions two skin sensitivity studies on 183 children ages 3 – 12 yrs which showed no adverse effects as well as no significant irritation from IPBC.

Since the early safety report, there have been a few reports of human skin sensitivity to IPBC in individual patients – all of which showed complete recovery after discontinuance of use of any product containing the IPBC which was presumably an allergen for these patients.

Post-1996 tests of human sensitivity to IPBC have all shown quite low sensitivity, having overall reported human skin testing (patch test) on 53,774 subjects with only 491 of those subjects showing any reaction (0.8%) to IPBC. 
In every study, positive patch test reactions occurred in less than 1% of subjects tested in all but one study. 
This is a very low reaction rate, but it is not zero, and the industry reports this low rate of reaction even though in the largest study of 25,435 subjects over 69% of the reactions were either weak or doubtful.

These combined studies showing prevalence of reaction below 1% means that IPBC at this time does not have the reaction rates necessary to be included as an allergen in standard allergy series. 
But, it remains under close monitoring as it is a relatively new preservative for cosmetic products and will presumably increase in usage.

Most human patch tests performed before 2004 were with 0.1% IPBC solutions, i.e. 10 times the concentration used in many cosmetic products. Some used 0.5% IPBC. 
In 2004, it was suggested that a better concentration for tests of this substance would be 0.2% and this has contributed to the diagnosis of more sensitizations to this substance.
One study showed significantly increased sensitivity between 2005 and 2010 using 0.5% IPBC in patch tests [Warshaw et al., 2013b].

Reactivity Profile
Iodopropynyl butylcarbamate is a carbamate ester. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates.

Contact allergens
Iodopropynyl butylcarbamate (IPBC) is a broad-spec- trum preservative used for years because of its wide field of application, in polymer emulsions and pigment dispersions such as water-based paints and adhesives, cements and inks, as a wood preservative, in metal- working fluids, household products, and cosmetics. Allergic contact dermatitis to IPBC was reported due to cosmetics, from sanitary wipes, and in metalworkers.

Contact allergens
Iodopropynyl butylcarbamate has produced slight irritation in rabbits. However, it was not found to be either a skin sensitizer or a photo sensitizer in guinea pigs. Cosmetic formulations containing up to 0.125% of iodopropynyl butylcarbamate produce no significant irritation or sensitization reactions in human repeated insult patch tests. Iodopropynyl butylcarbamate did not cause crosssensitization reactions in patients who had demonstrated sensitivity to related dithiocarbamate compounds. In the European Union, it is approved as a preservative up to 0.05% and is not to be used in oral hygiene or lip care products. If the concentration exceeds 0.02% in leave-on products, a warning label must indicate that the product contains iodine.

Clinical Use
Iodopropynyl butylcarbamate (3-iodo-2-propynyl-butylcarbamate) is a highly effective fungicide as well as a bactericide. It was first used in the 1970s as a film fungicide for paint and then as a wood preservative, where final use concentration up to 4% was permitted. For paint and coatings usually no more than 0.5% iodopropynyl butylcarbamate is used. For metalworking fluids, adhesives, textiles, and paper, concentrations between 0.1%and 0.2% are common. The Cosmetic Ingredient Review Expert Panel concluded that iodopropynyl butylcarbamate is safe as a cosmetic ingredient in concentrations less than or equal to 0.1%and that it should not be used in products intended to be aerosolized. By 1996, iodopropynyl butylcarbamate was used in 122 formulations reported to the United States Food and Drug Administration. Iodopropynyl butylcarbamate is found in a wide variety of occupational and consumer products, including shampoos, lotions, powders, makeup, baby products, paints, coatings, metalworking fluids, household products, cooling water, building materials, and contact lenses. It is an irritant, although at low concentrations few problems have been reported.

Iodopropynyl butylcarbamate or IPBC is a preservative used in wet wipes, paint, primers, coating and cosmetics to prevent bacteria and fungi’s in the products. It has been approved by the FDA for use as a component of adhesive that may safely be used in articles intended for use in packing and holding food. IPBC was developed in the 1970´s for industrial use in the wood industry as a preservative for paint and coating and in 1996 it was approved for cosmetics. In the EU, IPBC is not allowed in leave on products to small children (≤3 years).

The use of IPBC in cosmetics in the European Union is subject to the restrictions described in Annex VI, Part I of the Cosmetics Directive. Because of the iodine content the concentration allowed to use in cosmetic products is regulated to:

Rinse off 0,02 %
Leave on 0,01 %
Deodorants/antiperspirants 0,0075 %

So, what is the problem?

IPBC was for a long time considered to have a low allergenic potential. However because of the extended use in many products and the fact that it is a small molecule that can penetrate the skin, it can cause contact dermatitis in especially leave on products from specific product groups. Because of the wide use of IPBC a big populations study was done in Denmark from 2000-2011, where all patients who had a patch test were included in the study.

9755 patients were tested and 54 cases of allergy to IPBC was found.

Allergy to IPBC was significant more prevalent among men and patients with occupational dermatitis. The study concluded that IPBC continues to be among the less frequent allergens, and furthermore that IPBC allergy is typically related to men over 40 years old working in the wood industry and with hand eczema.

To conclude: In Denmark – and we believe this may be extrapolated to the rest of the EU – IPBC allergy is related to the male sex, age > 40 years, hand eczema, and occupational exposure. Physicians should be encouraged to investigate possible occupational exposure if IPBC sensitization is detected.  


What the experts say about IPBC

The safety of IPBC has been assessed by the Cosmetic Ingredient Review (CIR) Expert Panel twice. The first assessment was made in 1998 where the CIR Expert Panel concluded that IPBC was safe as cosmetic ingredient at concentrations ≤0,1 %, but it should not be used in aerosol products, because of a negative effect in lungs.

In 2016 new studies were made and a re-assessment on IPBC was made. CIR evaluated the updated scientific data and according to the panel there is a low degree of sensitization observed in some studies and mild dermal irritation potential of IPBC at concentrations of 0.5% and above. IPBC was negative in tests for mutagenicity, carcinogenicity and reproductive and developmental toxicity. The CIR concluded that IPBC was safe as a cosmetic ingredient at concentrations less than or equal to 0.1%, but IPBC should not be used in products intended to be aerosolized.

The Scientific Committee on cosmetic product intended for consumers (SCCNFP) is of the opinion that IPBC is safe for use in cosmetic products as a preservative at a maximum concentration of 0,05 %. The SCCNFP proposes the following further restriction or condition for its use in cosmetic products: the substance should not be used in oral hygiene and lip products. Leave on products containing more than 0,02 % IPBC must be labelled “contain iodine”.  



AllergyCertified make an allergy risk assessment for all ingredients used in a certified product. The assessment of IPBC shows that IPBC can be allowed in mascara since both the exposure and the concentrations (≤ 0,01 %) used in mascara is so low that it is safe to use. But in other products with a bigger exposure than mascara this preservative is not allowed because of the risk of getting an allergic reaction.
