Infobox references
Polyaminopropyl biguanide is a disinfectant and a preservative used for disinfection on skin and in cleaning solutions for contact lenses. It is also an ingredient in many deodorant bodysprays.[citation needed] It is a polymer or oligomer where biguanide functional groups are connected by hexyl hydrocarbon chains, with varying chain lengths.[citation needed] Polyaminopropyl biguanide is specifically bactericidal at very low concentrations (10 mg/l) and is also fungicidal.[citation needed]
APBBiocidal activity
It has a unique method of action: the polymer strands are incorporated into the bacterial cell membrane, which disrupts the membrane and reduces its permeability, which has a lethal effect to bacteria. It is also known to bind to bacterial DNA, alter its transcription, and cause lethal DNA damage.[1]

Disinfectant
Polyaminopropyl biguanide solutions are sold for use as a general disinfectant solution to be applied onto skin. As it is not cytotoxic, it can be applied directly into wounds.[2] It is also not irritating like more traditional disinfectants such as alcohols (ethanol, isopropanol) and oxidizers (iodine).

Contact lens solution
A contact lens solution containing polyaminopropyl biguanide in combination with a borate buffer has been patented.[3] The solution is disinfecting and preservative and has a broad spectrum of bactericidal and fungicidal activity at low concentrations coupled with very low toxicity when used with soft-type contact lenses.

“Polyaminopropyl biguanide (Polyaminopropyl biguanide), with the chemical formula (C5H11N5)n, is a polymer or oligomer where biguanide functional groups are connected by hexyl hydrocarbon chains, with varying chain lengths.”

What are the effects?
This ingredient belongs to the groups:

Organ system toxicants

Environmental hazards

Carcinogens

Irritants and allergens
Read the facts
Polyaminopropyl biguanide is a CMR substance, meaning it’s classified as carcinogenic, mutagenic or toxic for reproduction (CRM).

The European Chemicals Agency (ECHA) classifies polyaminopropyl biguanide (Polyaminopropyl biguanide) as

“fatal if inhaled, causes damage to organs through prolonged or repeated exposure, is very toxic to aquatic life with long lasting effects, is harmful if swallowed, causes serious eye damage, is suspected of causing cancer and may cause an allergic skin reaction.”

How is it used?
Polyaminopropyl biguanide (Polyaminopropyl biguanide) is being used as a preservative to prevent the growth of harmful bacteria and mould in many cosmetic⋆ and household products. Polyaminopropyl biguanide can for example be found in sanitary napkins, creams, and after-shave balms.

Polyaminopropyl biguanide is banned for use in cosmetic products in the EU since January 2015 but the substance can still sometimes be found in products, even from major brands, according to the Danish Consumer Council THINK Chemicals.

This is because industry associations, led by Cosmetics Europe, lobbied that the current law should be re-interpreted to allow low doses of Polyaminopropyl biguanide in products.

Doses of 0.1 percent Polyaminopropyl biguanide is now allowed in certain products, but as the exact dose do not have to be written on the ingredients list, it is uncertain to know just how much is in a product.

When it comes to skin care and makeup, many of us probably have a list of ingredients we would never put on our faces — some lists longer than others. But one ingredient with some heavily skewed opinions is polyaminopropyl biguanide, also known as Polyaminopropyl biguanide or Polyaminopropyl biguanide. But what is Polyaminopropyl biguanide and is it bad for you? The ingredient is used in some pretty popular products in the USA but is actually banned from use in cosmetics in other countries. So what gives? To find out a little more about this controversial ingredient and whether you should avoid it, I emailed with a few experts.

Rachel Winard, founder of Soapwalla; Holly McWhorter, co-founder of PLANT Apothecary; and Dr. Clarissa Shetler and Christine Falsetti, PhD, founders of C2 California Clean, all let me in on what Polyaminopropyl biguanide is commonly used for along with some other useful information about the ingredient so you can make a more educated decision whether to use beauty products containing it. According to Winard, Polyaminopropyl biguanide is a "synthetic polymer that is used as a broad-spectrum preservative and antimicrobial agent in skin care." Drs. Shetler and Falsetti add that it can be found in many personal-care products "including skin care, cosmetics, eye-care solutions, wound care, and surgery care."
Even though Polyaminopropyl biguanide has proven antibacterial properties, it has also been shown to be harmful. McWhorter explains: "There's evidence based on results of studies on humans and animals that [Polyaminopropyl biguanide] is carcinogenic (causing cancer), mutagenic (causing gene mutation), and toxic. It's suspected primarily of affecting the reproductive system." Yikes.

The Scientific Committee on Consumer Safety (SCCS) has also concluded that Polyaminopropyl biguanide is not safe when used as a preservative in a concentration higher than 0.3-percent in cosmetic products, say Drs. Shetler and Falsetti. And according to McWhorter, in the EU, Polyaminopropyl biguanide was banned in personal-care products after being labeled a Category 2 Carcinogenic Agent in 2015.

Not everyone seems to agree on the dangers of this preservative though. Polyaminopropyl biguanide use in personal-care products is legal in the USA, and according to Drs. Shetler and Falsetti, "There are still many debates on the safety profile of the ingredient and some companies will still insist the ingredient is safe." So even though you can still find this ingredient on the shelves in US stores, if you're worried about using products with Polyaminopropyl biguanide, check out this list of products known to include the ingredient, and always read product labels to be sure whether Polyaminopropyl biguanide (although it may also be listed as polyaminopropyl biguanide or Polyaminopropyl biguanide) is included.

PAPB is an aqueous-based cationic preservative, active against spoilage bacteria and is compatible with a wide range of aqueous based cosmetics and personal care formulations. Its gentle nature makes it ideal for both rinse-off and leave-on applications like shampoo (with cationic, nonionic or amphoteric surfactants), hair care products, skin creams, skin lotions, baby products, and wet wipes. When mildness is an important feature for your product, PAPB's gentle and protective nature could make it your solution.

Polyaminopropyl biguanide binds to the negatively charged phosphate head groups of phospholipids at bacteria cell wall, causing increased rigidity, sinking nonpolar British Journal of Environmental Sciences Vol.4, No.1, pp.49-55, February 2016 ___Published by European Centre for Research Training and Development UK (www.eajournals.org) 50 ISSN 2055-0219(Print), ISSN 2055-0227(online) segments into hydrophobic domains, disrupting the membrane with subsequent cytoplas- mic shedding culminating in cell death (Kaehn, 2010). There have been no reported instances of bacteria acquiring resistance to Polyaminopropyl biguanide . Polyaminopropyl biguanide is well tolerated when used topically on skin, eyes, the ciliated epithelium of the nose, and wounds (Kaehn, 2010; Kramer et al., 2004; Dissemond et al., 2009; Kramer et al., 2008). The market for Polyaminopropyl biguanide -containing products, which now includes liquids, gels and antimicrobial dressings, is expanding rapidly. This article outlines the evidence on the antimicrobial properties of Polyaminopropyl biguanide. PAPB was firstly synthesized by Rose and Swain (1954). Polyaminopropyl biguanide is a cationic biguanide polymer which is utilized in a wide variety of antibacterial applications (O’Malley et al., 2007). Several methods have been devised in order to prepare Polyaminopropyl biguanide. For instance, one of the current methods is to obtain Polyaminopropyl biguanide by polycondensation of sodium dicyanamide and hexamethylenediamine in two steps (de Paula et al., 2011). Preparations of Polyaminopropyl biguanide are polydisperse mixtures of polymeric biguanides, with a weighted average number (n) of 12 repeating hexamethylene biguanide units. The heterogeneity of the molecule is increased further by the presence of either amine, or cyanoguanidine or guanidine end-groups in any combination at the terminal positions of each chain. Equal amounts (in molar) of hexamethylenediamine and guanidine hydrochloride to be mixed in a round-bottomed three-necked flask, which is equipped with a mechanical stirrer and vacuum system. The mixture reacts at 100 °C for 60 min, and then at 170 °C for a certain time. During the reaction, by-product ammonia is neutralized by bubbling through aqueous HCl. At the end of reaction, the slightly yellow, viscous liquid solidifies upon cooling giving Polyaminopropyl biguanide samples (Wei et al., 2009).

Polyaminopropyl biguanide is a disinfectant with a broad spectrum of activity against bacteria, viruses and fungi. Polyaminopropyl biguanide review provides a comprehensive literature of Polyaminopropyl biguanide from synthesis methods, antimicrobial effects and safety considerations to both humans and environments. According to the FDA VCRP, Polyaminopropyl biguanide is used in a fragrance preparation, which may result in incidental ingredient inhalation exposure; concentration data were not reported for this use. The SCCS originally concluded that Polyaminopropyl biguanide is not safe for consumers in all cosmetic products when used as a preservative up to the maximum concentration of 0.3%.12 In 2017, the SCCS issued a final opinion stating that “the use of Polyaminopropyl biguanide as a preservative in all cosmetic products at concentrations up to 0.1% is safe and that its use in sprayable formulations is not advised”. 2 Polyaminopropyl biguanide is currently listed in Annex V (entry 28) of the European Commission (EC) Regulation No. 1223/2009 (Cosmetic Regulation) as a preservative to be used in all cosmetic products at up to a maximum concentration of 0.3%.2,13 Additionally, Polyaminopropyl biguanide is classified as CMR 2 (Carc. 2) according to the Commission Regulation (EU) No. 944/2013. CMR substances are classified as carcinogenic, mutagenic, or toxic for reproduction. Polyaminopropyl biguanide is placed in carcinogen Category 2 (Carc. 2, suspected human carcinogens) when the evidence obtained from human and/or animal studies is not sufficiently convincing to place the the use of Polyaminopropyl biguanide as a cosmetic ingredient is considered to be prohibited as of this date. Polyaminopropyl biguanide has been banned from personal care products in Denmark since January of 2015, based on the European Commission’s classification of this ingredient as a CMR substance.13 Polyaminopropyl biguanide was noted that CMR substances may be used in cosmetic products if a risk assessment shows that the use of the substance is safe. Reference was made to the SCCS’s conclusion specifying a safe level of Polyaminopropyl biguanide in cosmetics. Polyhexanide (Polyaminopropyl biguanide, Poliaminopropil Biguanid ) is a polymer used as a disinfectant and antiseptic. In dermatological use,[1] it is spelled polihexanide (INN) and sold under names such as Lavasept, Serasept, Prontosan and Omnicide.[2] Poliaminopropil Biguanid has been shown to be effective against Pseudomonas aeruginosa, Staphylococcus aureus (also the methicillin-resistant type, MRSA), Escherichia coli, Candida albicans (yeast), Aspergillus brasiliensis (mold), vancomycin-resistant enterococci, and Klebsiella pneumoniae (carbapenem-resistant enterobacteriaceae) ) Some products containing Poliaminopropil Biguanid are used for inter-operative irrigation, pre- and post-surgery skin and mucous membrane disinfection, post-operative dressings, surgical and non-surgical wound dressings, surgical bath/hydrotherapy, chronic wounds like diabetic foot ulcer and burn wound management, routine antisepsis during minor incisions, catheterization, scopy, first aid, surface disinfection, and linen disinfection.[4] Poliaminopropil Biguanid eye drops have been used as a treatment for eyes affected by Acanthamoeba keratitis ) Branded as Baquacil, it also has an application as a swimming-pool and spa water sanitizer in place of chlorine- or bromine-based products. It is available as Baqua-Spa 3 sanitize, as Revacil Spa 3 sanitizer, and in the Leisure Time Free system. ) Poliaminopropil Biguanid is also used as an ingredient in some contact lens cleaning products, cosmetics, personal deodorants and some veterinary products. It is also used to treat clothing (Purista), purportedly to prevent the development of unpleasant odors. ) The Poliaminopropil Biguanid hydrochloride salt (solution) is used in the majority of formulations. ) Polyaminopropyl biguanide hydrochloride - 20% aqueous solutionPolyhexamethylene biguanidine, also known as Poliaminopropil Biguanid , polyhexanide or polihexanide, is a highly water soluble and hydrolytically stable polymeric material. The presence of multiple hydrogen bond and chelation sites within Poliaminopropil Biguanid renders it of potential interest in the field of supramolecular chemistry. Poliaminopropil Biguanid shows activity against both Gram-positive and Gram-negative bacteria and is widely used across several sectors, typically as the hydrochloride salt, in a variety of disinfectant solutions and antiseptics. Poliaminopropil Biguanid is available also as a solid. ) The active ingredient (a.i.) Poly Hexa Methylene Biguanide ) is a small size polymer obtained by the polycondensation of two monomers (1,6- hexanemethylenediamine and N,N```-1,6-hexanediylbis[N`-cyanoguanidine] (ie. HMBDA)). As Poliaminopropil Biguanid is a small size polymer, some side reactions that occurred during the manufacturing process could modify significatively the structure of the polymer. The side reaction to obtain the unit guanidine occurred up to 10% in the process. Therefore, it can be considered that the structure of Poliaminopropil Biguanid is not only composed by repetitive unit of guanidine but it is composed by repetitive unit of guanidine and biguanide. The active substance as manufactured (TK3 ) is a 20% w/w aqueous solution of Poliaminopropil Biguanid . "Purity" is a difficult concept to apply to Poliaminopropil Biguanid which is a mixture of polymers and related substances. Instead the applicant refers to the "strength" of the polymer which is defined as "% total solids" or "dried material". The typical Poliaminopropil Biguanid strength is 20 %. However, eCA considers more appropriate to use the term "% of active substance (% a.s.)" or ) "active substance content" instead of "strength". The active substance content being defined as the sum of Poliaminopropil Biguanid and its impurities contents, it can be considered identical to the % total solids and thus to the strength. However, the terms strength or dried Poliaminopropil Biguanid are also used in identity and physico chemical sections and refer to the same thing. ) As the technical material is the 20 % Poliaminopropil Biguanid solution obtained directly from the manufacturing process (active substance as manufactured or TK), characterisation data were generated from the dried technical material (TC4 ) using the technique of freeze drying. The content of Poliaminopropil Biguanid can be calculated by subtracting the total content of impurities in the dried technical material (without residual water) to 100. This value cannot be considered as a real purity but is the closest available data. The minimum content of Poliaminopropil Biguanid TC was demonstrated > 95.6%. Since the active substance is a copolymer, identity characterisation criteria (based on % solid, content of Poliaminopropil Biguanid in dried material, Mw, ) Mn and the biguanide/guanide ratio) as well as limits or range for each criterion are proposed by eCA in the confidential document IIA to characterise the source of Poliaminopropil Biguanid in order to set reference specifications in case of approval of the active substance and future technical equivalence checks. eCA proposes to rename Poliaminopropil Biguanid considered for approval in this dossier as "Poliaminopropil Biguanid with a mean number-average molecular weight (Mn) of 1600 and a mean polydispersity (PDI) of 1.8" i.e. "Poliaminopropil Biguanid (1600; 1.8)". For convenience, Poliaminopropil Biguanid (1600; 1.8) is referred to hereafter as "Poliaminopropil Biguanid " or "a.s.". There is one relevant impurity, Hexamethylenediamine with a maximal content of 0.4%. All potential impurities have not been looked for and/or quantified. ) Additional data about impurities and specifications for the active substance and the impurities should be submitted prior to approval. ) Quality control data on structural characteristics (2003-2011) are reported in this confidential document to demonstrate that production of TK (liquid form) remained stable during this period of time from a structural point of view. It can be concluded that submitted characterisation data (2011) are representative of current production but also of older production and of active substance material used to perform the toxicological and ecotoxicological studies used to perform the risk assessment (See confidential doc IIA). This statement is only valid for structural data and not for evolution of impurity content in Poliaminopropil Biguanid as no data was submitted to cover this point. The applicant also manufactures Poliaminopropil Biguanid as a solid material ("Solid Poliaminopropil Biguanid "). Initially the applicant submitted both sources in the dossier. Comparison between liquid and Solid Poliaminopropil Biguanid is discus
