Prevents water loss: Thanks to its emollient properties, propanediol might soften and smooth skin by reducing water loss. Enhances preservative efficacy: Palep adds that propanediol can also function as a preservative booster in skincare products.
Propylene glycol is a small organic alcohol commonly used as a skin conditioning agent. It has been associated with irritant and allergic contact dermatitis as well as contact urticaria in humans; these sensitization effects can be manifested at propylene glycol concentrations as low as 2%.
Propylene glycol is a humectant, which means that it is an ingredient that is added to cosmetics to increase moisture retention in skin and hair. If these molecules are skin toxins like pollutants or harsh chemical ingredient, they could harm the lipid barrier and cause skin irritation.
1,2 hexanediol is a synthetic humectant, emollient, and preservative boosting ingredient. It is completely safe and common in many skincare formulations.
The National Center for Biotechnology Information lists panthenol as a skin protectant with anti-inflammatory properties. It can help improve skin's hydration, elasticity, and smooth appearance. It also soothes: red skin.
As an emollient, cetearyl alcohol is considered an effective ingredient for soothing and healing dry skin. Not only is it considered safe and nontoxic for use on the skin and hair, but it's also not drying or irritating like other types of alcohol.
Although PDO is categorized as a skin irritant, EWG notes that the health risks in cosmetics are low. And after a panel of experts working for the Cosmetic Ingredient Review analyzed current data on propanediol, they found it to be safe when used in cosmetics.
Some people believe that dimethicone is harmful because it's not natural. Others say that since it forms a barrier, dimethicone seals in oil, sweat, dirt, and other things that can clog pores and lead to acne. However, the amount of dimethicone in face and hair products is generally considered safe.
Propanediol: An alternative to Propylene Glycol.
Not vegan friendly. Glucose - Sometimes derived from animal tissues and fluids. Propanediol - Emulsifier - May contain animal fats.
Propanediol 1,3 can be used in creams, lotions, shampoos, conditioners, sun care and skin treatments. Usage Rate: 1-10%, added to the water phase.
Niacinamide helps build cells in the skin while also protecting them from environmental stresses, such as sunlight, pollution, and toxins. Treats acne. Niacinamide may be helpful for severe acne, especially inflammatory forms like papules and pustules. Over time, you may see fewer lesions and improved skin texture.
Zemea® propanediol functions well as an emollient, a humectant, an effective carrier of active ingredients, a preservative booster, a solubilizer, or a sensorial enhancer.
Propanediol, also called propylene glycol, is a clear, viscous, organic solvent derived from corn.
Sodium Hydroxide Safety: Yes, It's Safe!
Yes, if you see Sodium Hydroxide on the ingredients list of your favorite cleanser or skincare product, there's no need to be alarmed! It's FDA approved, and usually present in skin care to maintain a safe pH level in the product itself.Lecithin is found in egg yolks and acts as the emulsifier in sauces and mayonnaise. Lecithin also can be found in soy and can be used in products like chocolate and baked goods. Other common emulsifiers include sodium stearoyl lactylate, mono- and di-glycerols, ammonium phosphatide, locust bean gum, and xanthan gum.
In contrast to solubilisers, emulsifiers are not water soluble. Emulsifiers are used to emulsify oils in water to create O/W emulsions. Whereas with solubilisers you can incorporate only low concentrations of a lipophilic ingredient, (0.1 – 2.0%), with emulsifiers you can incorporate up to 50% oil in water.
Emulsifiers are used in creams and lotions to mix water with oils. Since water and oil do not mix but stay separated, an additional agent (emulsifier) is necessary to form a homogenous mixture keeping water and oil together.
In cosmetics, an emulsifier includes any ingredient that helps keep unlike ingredients (such as oil and water) from separating in an emulsion. Emulsifiers are widely used throughout the cosmetics industry and are the unsung heroes of many cosmetics formulas that blend and help to keep unlike ingredients together.
Here are the top 12 natural emulsifying agents for essential oils:
- Milk.
- Yogurt.
- Honey (where to get it)
- Aloe vera gel (where to get it)
- Liquid castile soap (where to get it)
- Alcohol.
- Gelatin.
- Salts.
The most commonly used food emulsifiers are lecithin; mono- and diglycerides of fatty acids and their esters with acetic, citric, lactic, and mono- and diacetyl tartaric or tartaric acids; polyglycerol fatty acid esters; polyoxyethylene sorbitan fatty acid esters (polysorbates); propylene glycol fatty acid esters;
Ethoxydiglycol is particularly appropriate for skin care preparations where it acts as an excellent solvent and carrier. Its solubility in ethanol, propylene glycol, vegetable oils, water, and butylene glycol makes it a valuable solvent or co-solvent which can be used in hydrophilic or lipophilic phases.
Natural solubilizers are very rare on the market. Most widely applied solubilizers are PEG-40 hydrogenated castor oil and polysorbate-20. Both of them are available under different commercial names and both of them are easy to work with and very forgiving ingredients.
How do you form an emulsion? If you add a drop or two of oil to water you can see that it does not dissolve or combine with the water: the oil floats on the water. If you shake the oil and water together then the oil breaks up into tiny droplets and becomes distributed in the water forming a mixture.
Propanediol, also known as 1,3-propanediol, is a colorless liquid that's naturally derived from corn glucose, or corn sugar. It can also be synthesized in a lab for use in personal products. In terms of chemical makeup, propanediol is an alkanediol, which consists of an alkane and a diol.
How likely is propylene glycol to cause cancer? The Department of Health and Human Services (DHHS), the International Agency for Research on Cancer (IARC), and the EPA have not classified propylene glycol for carcinogenicity. Animal studies have not shown this chemical to be carcinogen.
Very high amounts of propylene glycol were used in both of these studies, yet another study found effects at smaller doses. Summary At toxic levels, propylene glycol has been found to cause seizures and severe neurological symptoms. There have also been cases of nausea, vertigo and strange sensations.
Several brominated chemicals have been shown to be multisite-multispecies carcinogens in laboratory animals, and in this paper we report that the flame retardant, 2,2-bis(bromomethyl)-1,3-propanediol (BMP) is also a multisite carcinogen in both sexes of Fischer 344 rats and B6C3F1 mice.
Propanediol is a natural, ECOCERT and NPA approved emollient. It does not contain any preservatives or petro chemicals. Propanediol is plant based and Propylene Glycol is made of petro chemicals. Popular for its conditioning properties, Propanediol is used in hair care and skin care formulas.

Dimethicone forms a barrier on the skin that helps minimizes water loss. Dimethicone also helps improve the skin's smoothness and flexibility by filling gaps between the cells in the uppermost layer of your skin.
What is triethanolamine? It is a base which does contain three alcohol molecules but it is not an alcohol.
