It allows products to be applied in a smooth fashion to the skin and fills in wrinkles and lines for an even, smooth appearance of product. It is used in skin care products because it helps moisturize the skin without being too heavy. It fills in pores and smoothes blemishes as well. This ingredient can be mostly found in makeup and skincare products.

Is it safe?

There is some debate about whether dimethicone and other silicones should be used on the skin. Whilst these claims haven't been addressed in great detail when it comes to current published research, anecdotal evidence shouldn't be ignored and some users also simply dislike the texture of silicone-based products.

Dimethicone makes huge improvements to the texture of many skin products by acting as an emulsifier, preventing other ingredients from separating. It is also effective in creating a mattified finish, so is popular in skincare products for those with oily skin or large pores.

So yes, it is safe. Ultimately, it comes down to a personal choice. Some prefer products without dimethicone while other see Dimethicone is also used in creams to protect mild skin irritations, dry patches or healing wounds, and is effective at locking in moisture thanks to its larger molecules.

Polysorbate 20, also listed on an ingredient label as Tween 20, is formed by the ethoxylation of sorbitan before the addition of lauric acid. Let’s explain this in simpler terms. The process of making Polysorbate 20 begins with sorbitol, a sugar alcohol that can naturally be found in some fruits. The dehydration of sorbitol results in sorbitan. The next step in the process of making Polysorbate 20 is ethoxylation, which is a chemical reaction in which ethylene oxide is added to a substrate (in this case, sorbitan). Thus, sorbitan is reacted with 20 units of ethylene oxide (hence the 20 in this ingredient’s name). The final step is the addition of one lauric acid group esterified as the hydrophobic tail.

What is it used for?

Polysorbate 20 functions as a surfactant, emulsifier, and fragrance ingredient in skin care and cosmetic products.

Is it safe?

The Food and Drug Administration (FDA) approves use of polysorbate 20 as a synthetic flavoring substances at specified concentrations and formulations. The Cosmetics Ingredient Review (CIR) Expert Panel evaluated the scientific data and concluded that polysorbate 20 is safe for use in cosmetic formulations.

Bottom Line

Polysorbate 20 can safely be used on your skin. It functions as a surfactant, emulsifier, and fragrance is cosmetic and skin care products.

Carbomer:

What is it?

Carbomers are large molecules prepared from relatively small chemical compounds called monomes. The monomers used to make Carbomer polymers are acrylic acid and polyalkenyl polyethers. All of the Carbomer polymers are chemically similar, differing from each other in molecular weight and viscosity. Dry Carbomer polymers come in the form of white, fluffy powders.

What is it used for?

Interestingly, Carbomer doesn’t seem to have any effect on the skin at all. Once a Carbomer is applied to the skin and dries, you shouldn’t even notice it. Carbomers will not make the skin tacky, dry, or tight. The Carbomer polymers aren’t in the product to promote any benefits, just to improve the texture of the product.

Is it safe?

The safety of Carbomers has been assessed by the Cosmetic Ingredient Review (CIR) Expert Panel. Acute oral and dermal clinical studies with Carbomer polymers demonstrated that these ingredients have a low potential for phototoxicity, photo-contact allergenicity, skin irritation and sensitization at concentrations up to 100%. Upon evaluation of the scientific data, the CIR Expert Panel concluded that Carbomer polymers were safe as ingredients in cosmetics and personal care products.

Bottom Line

Carbomer can safely be used on your skin. It is a substance that has no effect on the skin but is used to improve the texture of the substance.

Disodium EDTA:

What is it?

Disodium EDTA (ethylenediaminetetraacetic acid) is a water soluble acid that is a strong emulsion stabilizer with chelating properties. It functions by bonding to metal ions in a solution, rendering them inactive.

What is it used for?

It helps to prevent cosmetic formulations and other personal care products, such as lotions and creams, from deteriorating. Disodium EDTA protects the integrity of skincare products from undergoing unwanted consistency changes, pH changes, odor changes, or texture changes. In addition, when binding with calcium, iron, or magnesium, Disodium EDTA results in enhanced foaming and cleaning abilities.

Is it safe?

Yes, it is commonly used in cosmetic and skin care products. It’s ingredients have been tested and do not present any negative effects on a person’s skin.

Bottom Line

Disodium EDTA can be safely used on your skin. It prevents lotions from deteriorating and enhances foaming and cleansing abilities.

Sodium Chloride:

What is it?

Sodium Chloride, or table salt, is a white crystalline solid. In cosmetics and personal care products, Sodium Chloride is used in the formulation of oral hygiene products, shampoos, fragrance, skin, hair, nail, cleansing, suntan, makeup and bath products.

What is it used for?

Used primarily as a binding agent in skincare products and occasionally as an abrasive in scrub products. Perhaps the most common use of sodium chloride in cosmetics is as a thickening agent. Salt is commonly used to thicken the water (also known as aqueous) phase of shampoos, body washes, and non-soap facial cleansers. It’s an inexpensive and highly effective, versatile ingredient included in numerous types of cosmetics.

Is it safe?

Yes, Sodium Chloride is considered a relatively safe ingredient, although the Cosmetics Database has given it no official rating but still considers it a low hazard.

Bottom Line

Sodium Chloride can be safely used on your skin. It is used as a binding agent in skin care products as well as a thickening agent.

Phenoxyethanol:

What is it?

Phenoxyethanol is a preservative used in many cosmetics and personal care products. You may have a cabinet full of products containing this ingredient in your home, whether you know it or not.

What is it used for?

It’s often used as a preservative or stabilizer for other ingredients that might otherwise deteriorate, spoil, or become less effective too quickly.

Is it safe?

Yes. The FDA currently allows the use of this ingredient in cosmetics, and as an indirect food additive. An expert panel from The Cosmetic Ingredient Review (CIR) first reviewed all available data on this chemical in 1990. They deemed it safe when applied topically in concentrations of 1 percent or lower. In 2007, the panel reviewed newly available data, then confirmed their former decision that it’s safe for adults to use topically in very low concentrations.

Bottom Line

Phenoxyethanol can be safely used on your skin. It is commonly used in skincare as a preservative and a stabilizer.
