Octenisept

Octenisept is a German range of antiseptic products made by Schülke & Mayr GmbH, the hygiene company based in Norderstedt, Germany. The range is built around octenidine, an antiseptic substance that Schülke's own researchers developed in the mid-1980s, and the first octenisept product went on sale in 1990 as an antiseptic for the mucous membranes [7]. Over the following decades the name has grown from a single solution into a family of wound sprays, gels, intimate-care products and mouth rinses.

Octenisept is not a cosmetics label in the usual sense. Its core products are antiseptics used on wounds, skin and mucous membranes, and it sits closer to the pharmacy shelf than the beauty counter. Its wide use in medicine has also brought it attention from regulators and doctors, who have documented serious reactions when the product was used in ways it was not intended for.

Octenisept has no individual founders. It came out of in-house research at Schülke, a company that had already spent nearly a century in hygiene and disinfection when the work began. According to the manufacturer, its researchers were looking for an antiseptic agent suitable for the inside of the mouth when they first synthesised octenidine in the mid-1980s, and found that the new substance combined strong effect with good tolerability.

Schülke describes octenisept as the product with which "the agent's success story began". The company dates the brand's launch to 1990 [7]. A different date sometimes appears in connection with the name: the active ingredient octenidine has been used in European medical settings since 1987 [8]. The two years describe different things. 1987 refers to the substance in medical use, while 1990 is the year the manufacturer gives for the launch of octenisept itself.

The parent company is much older than the brand. Rudolf Schülke and Julius Mayr founded it in 1889, at a time when, as the company puts it, knowledge about hygiene and disinfection was not widespread [6]. Their first branded disinfectant was Lysol, and the company later developed Sagrotan, which it describes as the first disinfectant for private households. Both of those brands were eventually sold to Reckitt Benckiser and are no longer part of Schülke. In the company's own retelling of its history, octenisept appears as the next landmark in that line: an innovation in the market for mucous membrane antiseptics.

After its 1990 launch for mucous membranes, octenisept gained a second use. In 1995, its licensed use was extended to antiseptic wound treatment [7]. That extension shaped how the product is known today. On its German website, the wound disinfection spray is presented as the flagship, and the company calls it the first wound antiseptic with octenidine in Germany [4].

Schülke also says that octenisept quickly became the market leader in wound and mucous membrane disinfection. Its brochure supports the statement with a footnote to 2021 sales data from IMS Health [7]. The claim comes from the manufacturer and has not been independently assessed.

Octenisept is owned and marketed by Schülke & Mayr GmbH, which operates the brand's website from its address in Norderstedt, Germany [3]. The website itself presents the range as "octenisept® by Schülke". The company's managing director is Jan-Dirk Auris.

Within Schülke, octenisept is one of several brands that use octenidine as their active ingredient. The company lists octeniderm, octenisan and octenilin among its other octenidine brands, which together span skin, mucous membrane and wound antiseptics as well as antibacterial personal and oral hygiene. Octenisept's mouth rinses are sold under the closely related name octenident.

The brand's German website frames the whole range with the line "Von Kopf bis Fuß gegen Infektionen", which translates as "from head to toe against infections" [2]. The products are grouped around three areas: wounds, intimate health and oral hygiene. Each area is presented through practical guidance, covering topics from cuts, burns and insect bites to tattoo aftercare, vaginal infections and gum inflammation.

The tone is medical rather than cosmetic. The company says its products contain octenidine and that their effect and tolerability have been confirmed in scientific studies. It stresses features such as painless application, and says the wound spray is colourless and odourless. Several products are described as suitable for babies and young children, and the wound spray is also described as suitable during pregnancy from the fourth month.

The parent company places this work under its wider mission, "We protect life worldwide". That statement belongs to Schülke as a whole rather than to octenisept specifically, but it explains the brand's focus on preventing infection rather than on appearance or fragrance.

The central idea behind the range is the pairing of octenidine with phenoxyethanol. Octenisept describes this combination as a clinically proven active duo that kills germs, and says it works against bacteria, fungi and certain viruses. The company states that its wound spray disinfects within 60 seconds. On the product page, users are told to spray the wound fully, leave it for one to two minutes and then cover it with octenisept Gel.

Octenidine itself is a cationic surfactant, a type of compound that disrupts the workings of microbial cells. It has been used in Europe as an alternative to chlorhexidine, an older and widely used antiseptic, partly because of chlorhexidine's slower action and concerns about an impurity it can contain [8]. Preparations of octenidine may contain phenoxyethanol, as octenisept does.

The current range on the German website has eight products:

- Wund-Desinfektion Spray, the wound disinfection spray, for cuts, grazes, burns, shaving nicks, insect bites and the care of a newborn's navel. - octenisept Gel, a wound gel that the company says supports natural healing and reduces scarring. - Vaginaltherapeutikum Spray, a spray for fungal and bacterial vaginal infections. - Intima Wash Lotion SOS, an intimate wash for use alongside treatment of vaginal infections. - Daily Intima Wash Lotion Sensitive, a daily intimate wash with allantoin, described as microbiome-friendly. - protect & repair cream, a cream for closed, healing wounds made with panthenol, bisabolol, octenidine and petroleum jelly, and free from fragrance and colourants. - octenident antiseptic, a mouth rinse aimed at gum inflammation and periodontitis. - octenident Hygienische Mundspüllösung, a mint-flavoured mouth rinse against odour-causing bacteria.

The protect & repair cream is the product closest to everyday skincare. It is classed as a medical device and is aimed at adults, children from six months, people with incontinence and intensive-care patients, as well as at preventing nappy rash. The fragrance-free claim applies to this cream rather than to the range as a whole. No third-party certifications for the range are documented.

The most serious concerns about octenisept relate to misuse in deep wounds. In 2020, Swissmedic, the Swiss agency for therapeutic products, published a warning about the product being used to rinse deep wounds [9]. It described the case of a girl whose puncture wound to the foot was irrigated with octenisept, which led to inflammation of the muscles and surrounding tissue in the sole of the foot and several weeks in hospital. The regulator noted that tissue death, redness and lasting swelling are possible reactions after deep-wound irrigation.

According to Swissmedic, the product information already carried a boxed warning, and the packaging stated that octenisept must not be introduced into deep tissue with a syringe and is intended only for surface use. Even so, the agency said that cases were still being reported despite this warning.

A second report came from dermatologists in Poland. In 2018, the peer-reviewed journal Dermatology Review published a case of a four-year-old girl who developed a blistering skin reaction after octenisept was applied to a graze three times at twelve-hour intervals [10]. Red, swollen bumps appeared within hours and were followed by blisters, and the lesions persisted for weeks despite treatment. The authors noted the wide use of octenisept across many fields of medicine and called for more research on the product's potential to cause allergic reactions and on its toxicity.

Broader concerns about the active ingredient have also been recorded. A 2016 survey of German neonatal intensive-care units reported blistering, tissue death and scarring when octenidine was used without phenoxyethanol, and wound irrigation with octenidine has been linked to tissue damage in penetrating hand wounds [8].

Octenisept is an active brand. Its German website presents a current range of eight products across wound care, intimate health and oral hygiene, and the brand continues to be marketed under the Schülke name. Schülke & Mayr GmbH in Norderstedt remains the company behind it.
