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.

Octocrylene
UV Protection
Octocrylene is an organic chemical sunscreen. It protects against UVA and UVB rays that can damage your skin or even lead to melanoma. It also stabilizes other sunscreen ingredients in a formulation and increases the water resistance of a product. It is approved by the FDA in concentrations of up to 10%. It’s not a very effective component on its own, that’s why manufacturers combine it with other chemical sunscreens.

Pentylene Glycol
Roles: Skin conditioning, Solvent
Moisturizing
Hair conditioning
Pentylene Glycol is a great replacement for Propylene Glycol. It has very similar characteristics but it’s derived from plants (usually from corn). Natural cosmetics lovers will find this component very useful. It enhances the moisturizing effect of cosmetic products, improves the efficiency of preservatives and it’s an effective emulsifier. It’s approved by ECOCERT and COSMOS so it’s considered to be 100% safe and can be used in vegan products.
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.
6
Avobenzone
UV Protection
Avobenzone is the only chemical UV-protection component with a broad spectrum coverage. It can help to block both UVA I and UVA II rays. It's safe and it is allowed to use at a 3% concentration in the USA and a 5% concentration in the EU countries.
There is one problem: avobenzone loses efficiency when exposed to the sun. If you are outside, it loses 36% of its ability to block UV rays an hour after application. That's why it's recommended to reapply sunscreen every 2 hours.
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.
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.
14
Silica
Silica is used for improving texture of the product. It helps the product to spread out evenly. Very often it’s used in different exfoliants as an abrasive. It's safe and non-toxic.

Fragrance
Roles: Deodorant, Fragrance, Masking
Fragrances
Fragrance is a mix of chemical ingredients (usually 20-30 chemicals but up to 200 sometimes) that help the product to smell better. It can hide many bad things. Synthetic fragrances may contain many different chemicals, but manufacturers don’t want to reveal each of them for some reason and hide them behind the word "Fragrance".
19
Sodium Carbomer
Roles: Emulsion stabilizer, Film former, Gel forming, Viscosity controlling
20
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.
21
Tetrasodium EDTA
Roles: Chelating
Tetrasodium EDTA is a formulation component. It is a pH adjuster and chelate. It prevents other components from reacting with each other making the product live longer.
22
Ethylhexyl Methoxycinnamate
23
Acrylates/Vinyl Isodecanoate Crosspolymer
Roles: Emulsion stabilizer, Film former, Viscosity controlling
24
Phenoxyethanol
Roles: Fragrance, Preservative
Antiseptic
Phenoxyethanol is one of the most popular preservatives. It kills bacteria and makes the product live longer. Manufacturers like this ingredient because it can dissolve in any liquid, even in oils.
Another purpose of this component is the fixation of aromas in perfumery. Phenoxyethanol is also used as a strong antiseptic and a good antibacterial agent. It is widely used in dermatological cosmetics alongside natural antiseptics such as chamomile, sage, and calendula.
25
Sorbic Acid
Roles: Fragrance, Preservative
Antifungal
Sorbic Acid is a very effective synthetic preservative that is used even in food. It’s considered to be safe for use in cosmetic products. It’s great for increasing the shelf life of a product.

Roles: Fragrance, Masking
Allergens
Hexyl Cinnamal is a fragrance component that gives the product pleasant cinnamon and light jasmine aroma. It’s also used to enhance other fragrances. It’s considered a skin sensitizer and manufacturers have to call out this component on an ingredient statement.
27
Linalool
Roles: Deodorant, Fragrance, Masking
Allergens
Linalool gives the product a nice and fresh lavender scent. It can be found in many essential oils. It oxidizes during air exposure and becomes allergenic. It can lead to irritation causing problems for people with sensitive skin. The threat is even higher if the product was opened several months ago. In such products, more Linalool is oxidized.
28
Limonene
Roles: Fragrance
Antiseptic
Allergens
Limonene provides a nice and fresh citrus scent. It can be found in many plants. It's used in cosmetics because of its low price and pleasant smell.
