At DEMAIN®, you won't find any parabens, PEGs, silicones, phthalates or controversial preservatives in the formulas. The ingredients of our cosmetic treatments are 100% of natural origin and 100% healthy to preserve your health and your skin!

Here is the list of ingredients that you will never find in a DEMAIN® cosmetic product:


  • Phenoxyethanol: Preservative, easily absorbed through the skin, prohibited for children under 3 years on products intended for the seat, it is suspected of being an endocrine disruptor (harmful for hormonal balance, which can lead to cases of sterility) . Tolerated by regulations at 1% in adults, the cocktail effect of this ingredient present in most conventional cosmetics is feared.
  • Parabens: Used as preservatives in many formulas, parabens starting with P or B (like Pas Bon) are endocrine disruptors.
  • Silicones (dimethicone, cyclopentasiloxane, cyclomethicone): Used to add slipperiness to formulas, silicones are suspected endocrine disruptors. Derived from plastic, very little biodegradable, they pollute the environment by flowing into wastewater.
  • Ethylhexyl Methoxycinnamate (or octyl methoxycinnamate): This compound is an anti-UV filter found in cosmetic products other than sun creams such as day creams or foundations. It is considered an endocrine disruptor.
  • Phthalates (dibutyl phthalates, DBP, DEHP, DEP): fixing agents, thus allowing perfumes to last longer or preventing varnishes from flaking, they are suspected of being endocrine disruptors.
  • BHA (Butylhydroxyanisole): It is an antioxidant used to prevent the rancidity of fatty substances. It is suspected as an endocrine disruptor. It is classified as a possible carcinogen by the IARC (International Agency for Research against Cancer) and is also said to have a toxic effect.
  • BHT (Butylhydroxytoluene): Also antioxidant. It is often used and mainly to replace BHA. BHT would also be an endocrine disruptor and would also have other more toxic effects on the liver, kidneys or lungs.
  • Butylene-Glycol: Humectant, when it comes from petrochemicals, it is suspected of being irritating or even toxic and can cause reproductive disorders. In addition, it is non-biodegradable.
  • Propylene-Glycol: Preservative, suspected carcinogen and reproductive harm, non-biodegradable.
  • Benzophenone: Photo-sensitiser, suspected of being an endocrine disruptor and highly allergenic.
  • Triclosan: A powerful antimicrobial (often found in toothpaste and antibacterial soaps), it is suspected of being an endocrine disruptor, irritating to skin and eyes and very toxic to aquatic organisms.


  • Sulfates including Sodium Lauteth Sulfate (SLS): Synthetic sulfur-based ingredient and foaming agent found in many rinse-off products that can be harsh and irritating to the skin.
  • Toluene: Volatile solvent, pollutant, irritating to skin, eyes and respiratory system.
  • Methylisothiazolinone (MIT): Powerful preservative, often used to replace parabens, but which is irritating and can cause contact dermatitis.
  • P-phenylenediamine and its derivatives: Present in permanent hair coloring and temporary tattoos. These are so-called sensitizing ingredients, likely to cause major allergies. Many cases of eczema have been reported among users and hairdressers.


  • PEG: Derived from petroleum, PEGs are used as a thickener, emulsifier, surfactant or humectant. Although commonly used in cosmetics or shampoos, PEGs are suspected carcinogens and are also very poorly biodegradable. They accumulate in nature through the flow of wastewater.
  • Mineral oil, including paraffin oil: Coming from petrochemicals, purely synthetic, they are widely used in cosmetics because they are less expensive than vegetable oils. They have no nutritional value for the skin. Worse, they are occlusive and prevent it from breathing. Depending on their degree of refining, they are likely to be carcinogenic to humans.
  • Formaldehyde: Preservative suspected of being carcinogenic.
  • DEA/MEA/TEA: Foaming agents and allowing to achieve creamy textures. Potentially carcinogenic and irritating substance.


For your pleasure and your well-being, we have also made the choice of sensoriality versus that of neutrality for our formulas and have therefore decided to perfume most of our products with 100% natural perfumes, although the applications of cosmetic analyzes classify certain natural perfuming ingredients as risky ingredients.


Fragrance allergens are molecules naturally present in fragrancing substances and which can cause allergic reactions in people who are sensitive to them. These are not ingredients that the manufacturer voluntarily adds to the formula, but substances contained in the ingredients that make up the perfume. Due to their allergenic nature, some of these substances are regulated in order to limit the risks of contact allergies for consumers. Dosage, mentions to be affixed to cosmetics… Everything is strictly supervised.


The risks associated with perfume allergens are risks of irritation or allergies only for people sensitive to these substances : redness, itching, etc.
We cannot therefore speak of “danger” , as we would for ingredients known to be carcinogenic, for example. Since these risks of reactions are quite limited, the mention of these ingredients in the INCI lists has more of an informative rather than a health purpose. The aim is to facilitate their detection for sensitive people. The CSSC has also published an information sheet explaining that 1 to 3% of the European population has declared an allergy due to perfumery ingredients.

In conclusion, we can say that perfume allergens are to cosmetics what nuts are to food products. They are mentioned on the packaging to reassure people who do not support them, but they are not dangerous for non-allergic people. In food, the presence of these allergens does not affect the overall score of the product.
