Definitions
- hydroperoxyalcohols and their derivatives as antimicrobial agents
- the invention relates to the use of a compound of hydroperoxyalcohol type, or a 1,2,4-trioxane thereof, as an antimicrobial agent, making it possible to envisage its use in various applications and in particular as a preservative and / or. to improve the antimicrobial properties of at least one preservative, to modulate the skin microbiota, in the treatment or prevention of a disease of the skin, mucous membrane and / or integuments or even to sanitize, sanitize, disinfect and / or sterilize a surface other than the skin, integuments and mucous membranes, in particular a hard surface or a textile. It also relates to a composition, in particular cosmetic or dermatological, comprising such a compound.
- the ozonides vegetable oils are known since the early 20th century.
- the first processes used oxygen (US 984,722) then since the mid-1980s, the processes are based on ozone (US 4,591, 602), this gas making it possible to obtain a higher peroxide number and which gives thus with ozonated oils obtained with antibacterial, antifungal, antiviral, anti-inflammatory, analgesic and immunomodulatory properties, in particular for infections of the skin and mucous membranes (Koech, Afr. J. Health Sci. 2008, 15, 1).
- ozonated oils often have a reputation for emitting an unpleasant ozone odor.
- Benzoyl peroxide is widely used in the treatment of acne, but this product has the disadvantage of being irritating to the skin.
- These compounds can be used either as preservatives in various types of products, in particular cosmetic products, or as antimicrobial disinfectants, or even to modulate the skin microbiota.
- the skin microbiota is made up of around 1 million germs per cm 2 and is therefore made up of several hundred distinct species, including bacteria, fungi, parasites and viruses. It includes in particular the transient flora formed of microorganisms that are found more or less durably on the skin, depending on the environmental conditions (humidity, pH, temperature) and the state of health of the subject. These microorganisms are generally harmless, but some can cause disease. Their development is blocked by the microorganisms of the commensal flora (or resident flora) which inhabit the horny layer and the superficial layer of the epidermis and which live at the expense of their host without causing damage.
- the commensal flora forms a unique and complex balance, one of the main functions of which is the body's defense against pathogenic microorganisms.
- Staphylococcus epidermidis 5 (Gram +) is one of the most abundant bacteria in the skin microbiota, which helps the skin to synthesize antimicrobial peptides interfering with colonization of the skin by Staphylococcus aureus (Gram +), which is a common pathogen.
- Microorganisms can be classified according to the two types of flora.
- the microorganisms of the commensal flora are for example the Propionibacteriaceae (in particular Cutibacterium acnes, P granulosum and P avidum), the Staphylococcaceae (for example S epidermidis, S hominis, S hameolyticus, S aureus and S simulans), Micrococcaceae, Corynebacteriaceae (for example C. xerosis, C. jeikeium and C.
- the microorganisms of the transient flora are, for example, Staphylococcaceae (S aureus), Streptococcus, Enterobacteriaceae, Pseudomonadaceae, Bacillaceae of the genus Bacillus (for example B neisseria), and yeasts of the Candida type (in particular C albicans and C parapsiloopsis).
- the skin microbiota which is specific to each individual, can be subject to multifactorial variations, depending in particular on the area of the skin concerned (armpits, navel, soles of the feet, scalp, back, etc.), physical characteristics. chemical (humidity, salinity, temperature, pH, sweat, sebum), endogenous characteristics (subject's sex, age, genetic factors) and exogenous characteristics (use of cosmetics and hygiene products, lifestyle, exposure to the sun, environment). It forms a symbiosis with the skin. Maintaining the balance of the skin microbiota is essential for preserving the protective functions of the skin. When there is an imbalance, or dysbiosis, skin disorders can appear. The regulation of the skin microbiota makes it possible in particular to strengthen the barrier function of the skin, including the scalp, and thus improve its hydration, reduce skin irritation and the formation of scales and dandruff.
- hydroperoxyalcohols or beta-hydroxy hydroperoxides
- 1,2,4-trioxanes obtained from the latter
