Water is a great solvent. It’s neutral and doesn’t provide any strong positive or negative effects. It just helps components to mix better and to transport active components.
Glycerin is one of the most outstanding and helpful skincare components. It's used in many skincare products because it works and provides notable results. It's one of the best moisturizers. Molecules of Glycerin can absorb water and deliver it into deep layers of the skin making it hydrated.
Propylene Glycol is a useful componet with many positive effects. It’s a very good moisturizer. It helps to deliver ingredients into deeper layers of the skin. It creates a protective layer on the skin preventing water loss. The component is researched very well and doesn’t have notable side effects. It’s used even for making food.
Cetyl Alcohol is a fatty alcohol. It’s responsible for making your skin soft and improving product thickness. It makes the product easier to apply and feel richer. Though it contains the word “Alcohol” in its title, the component doesn’t belong to harmful alcohols. That’s why a product with this component can still be marked as Alcohol-free. Usually, manufacturers receive this component from coconut or palm oil.
C12-15 Alkyl Benzoate is mostly used as formulation component. It gives the product a soft and silky but non-greasy feeling. As for the skin benefits, it's an emollient – it makes the skin softer and more hydrated. It also helps to kill bacteria and increase the product’s shelf life.
Stearyl Alcohol creates a barrier on the skin's surface lowering the evaporation of water and making it hydrated for a longer time. This barrier helps the skin to recover after deep cleansing. It also makes the skin look smooth. Though it belongs to alcohols, it's a fatty alcohol and it doesn't make your skin dry.

Comedogenic rating [ 3 ]
Bad for oily skin
Glyceryl Stearate SE is a nice moisturizing ingredient. It hydrates the upper layers of the skin and fills small wrinkles. In haircare products, it's used for making hair softer.

PEG
Peg-100 Stearate is a good emulsifier that makes the ingredients mix nicely. It also makes the skin soft and moisturized. Peg-100 Stearate is also known for its cleansing effect. CIR Expert Panel marked this ingredient as safe.
Dimethicone is the most popular silicone. It makes the skin softer and forms a film adding smooth and silky feeling. This film not only improves how the skin feels but also works as a protective barrier. It also improves the visual appearance of your skin by filling small wrinkles. That's why some people think dimethicone removes wrinkles. Actually, it does not. It's just a visual effect.
One of the most important characteristics of this component is that it helps to spread other ingredients evenly on the surface to provide good coverage. It's very important because you want all your skin cells to receive an equal proportion of the components.
Dimethicone is considered as safe, but remember that it is rather difficult to wash off! This may lead to clogged pores and acne if you use it too often and don't wash off quite well.
Cyclopentasiloxane is a fluid silicone. It’s non-greasy and doesn’t have any scent or color. It evaporates pretty fast which makes this ingredient essential when it comes to making products that have to dry quickly. It also gives a nice silky feeling when you apply the product to the skin and hair. It leaves a thin film that protects the skin after evaporation.
Cyclopentasiloxane is chemically neutral, meaning it doesn’t react with other components.
Palmitic Acid is an emulsion stabilizer. It reduces water evaporation from the surface of your skin. That’s why this component is good if you suffer from dryness. It also increases the efficiency of other surfactants in the formulation. It can be found in many organic oils including Avocado oil, Cocoa oil, Olive oil etc.
Stearic Acid doesn’t belong to aggressive acids. It’s a fatty acid that can be found in Shea Butter, Cocoa Butter, and many natural butters and oils. The component is mostly used for formulation purposes. It makes the product spread and feel better. It’s one of the most important fatty acids in our skin cells.
Salicylic Acid is an amazing component for oily skin. It’s a famous BHA that chemically exfoliates dead cells, kills bacteria, and prevents acne. It works as a strong pores cleanser. AHAs are not effective for removing sebum from pores, while BHAs are leaders in this space. Salicylic Acid also helps to shrink pores, remove acne scars and make skin tone even. Pay attention: concentration matters! This ingredient is rather aggressive. It can lead to irritation in high concentrations. If your skin has never seen this component before test the product first.

Carbomer
Roles: Emulsion stabilizer, Gel forming, Viscosity controlling
Moisturizing
Carbomer is used for formulation purposes. It helps to control the viscosity and flow of a product. It’s considered safe but only if it’s well purified. Poorly purified carbomers may contain benzol which may lead to irritation.

Acrylates/C10-30 Alkyl Acrylate Crosspolymer
Roles: Emulsion stabilizer, Film former, Viscosity controlling
AcrylatesC10-30 Alkyl Acrylate Crosspolymer is a synthetic non-toxic gel used mostly for formulation purposes. It helps manufacturers to achieve the necessary texture of the product (it makes the product thicker). It also has sight healing and antistatic activity.
25
Sodium Chloride
Roles: Flavoring, Viscosity controlling
Antiseptic
Sodium Chloride is a very famous ingredeint also known as Salt. Yes, it’s the same salt you can find on your table. In cosmetics, it is used as a preservative helping the product to live longer. It is also used as a peeling agent in different scrubs. Human contact with this element since ancient times and that's why it is 100% safe.
26
Disodium EDTA
Roles: Chelating, Viscosity controlling
Disodium EDTA is an emulsion stabilizer and chelating agent. It deactivates the metal ions preventing them from reacting with other active ingredients. It improves the stability of a cosmetic formula and keeps the product’s consistency, texture, and pH unchanged. It doesn’t have any skincare effects and is used for formulation purposes only.
27
Sodium Hydroxide
Roles: Buffering
Sodium Hydroxide is used mostly for formulation purposes. It helps to hold the pH level of a product. It also works as a chemical exfoliator that removes dead cells. Usually concentration of this component is low in skin care products and it’s used mostly for adjusting pH.
Lactic Acid is the most popular and the least aggressive acid among all the AHAs. Unlike Salicylic and Glycolic acids which can irritate your skin, Lactic Acid will hardly cause any problems. The combination of its soft action and effectiveness makes it a real brilliant. It exfoliates dead cells, makes the skin tone even, clears pores, kills bacteria, moisturizes the skin and helps to keep water, helps the cells to produce Hyaluronic Acid. It also works as a strong antioxidant and anti-aging component.
It's a great acid for getting familiar with the world of AHAs. If you want to start using "fruit acids" but struggling for some reason, try to use Lactic Acid first. If your skin accepts it well, you can try stronger acids.
Methylparaben is an effective preservative. It is a controversial ingredient in terms of safety. In 2006 there was a laboratory test showed that this component can increase the sun sensitivity of the skin cells. That’s why it’s a good idea to use sunscreen after you use this component.
