Hello everyone, I really enjoyed writing about what was in my Nivea Lipbalm last week, and thought, hey why not do it again?  So today I will be talking about what’s in the Kat Von D Lock-It Hydrating Primer.  I have been using this for a while, and I do quite like it.  It’s great for more dry skin types, I use it under the YSL All Hours foundation to keep my skin hydrated.  However, weirdly enough it can make my nose a little oily underneath; something that never happened before using this primer.  This shows that it really is good for dry skin types, super hydrating.

I use the EWG Skincare Database for most of my ingredient information.  Check them out here.

Water:  Well, water’s all good! Yay love water.  Oon a side note, this is a water-based primer, thus meaning it’ll work best with water-based foundations.

Shea Butter Ethyl Esters:  Derived from Shea Butter, but made to be less greasy/thick.  This is going to be super moisturizing.  Coming from a tree in Africa, shea butter is a natural ingredient too yay!  Also, low toxicity!  

Jojoba Esters:  Somehow made by science, using jojoba oil in a process called “transesterification/interesterification”.  This appears to be something to do with fatty acids and alcohol.  I think it makes things more moisturizing?  Check out the explanation of these words here.  This moisturizes, soothes and hydrates the skin.  Also with a low toxicity score that’s great.

Isododecane:  Adding this ingredient makes it all the more moisturizing.  Its uses also incure being a fragrance booster, and a solvent too.  This has a low toxicity score too, which is awesome, this seems to be doing well so far.

Hydrogenated Polydecene:  I feel like I keep repeating myself, but this is another moisturizer.  I know, what a surprise!  Uses also include being a solvent and fragrance component.  It has a low toxicity score too.

Glycerin:  This, again is another moisturizer, fragrance component, solvent and more (more that’s not related to makeup).  It is usually a by-product of soap, made with animal fat, however, this primer is vegan, so no fat!  Kat Von D is cruelty-free so happy animals all round.  This has a low toxicity score.

Potassium Cetyl Phosphate:  This is an emulsifying agent and a surfactant.  This basically means that it helps keep everything together, whilst regulating the thickness/texture of the product.  This has low toxicity also.

Polyurethane-34:  Really hard to find information specific to Polyurethane-34, however, it seems to be completely safe and low toxicity.  I could, however, find information on just straight Polyurethane.  It appears to manage the way a formula works/the texture of the product.  There really isn’t much information out there, however, I can say that Polyurethane itself has a low toxicity score too.

Vp/Eicosene Copolymer:  This is another ingredient that will help with the viscosity and binding of the formula.  It is a synthetic polymer of a hydrocarbon eicosene and vinylpyrrolidone and has low toxicity.

Phenoxyethanol:  This is a preservative.  It can have some issues with irritation.  I’ve never had irritation with this product and I have sensitive skin and psoriasis on my face.  However, patch test before use.  Unfortunately, this ingredient does have a medium toxicity score.

Cetyl Alcohol:  This ingredient manages texture.  It can also be a fragrance component.  This can be an animal-derived ingredient, however as this product is vegan, we know it wasn’t.   This has a low toxicity score.

Glyceryl Oleate Citrate:  This is another surfactant/ emulsifying agent, same as Potassium Cetyl Phosphate, above.  Also has a low toxicity

Caprylyl Glycol:  One of these things is not like the other… It’s Caprylyl Glycol!  It’s not just a moisturizer, but is also antimicrobial!  It’ll help inhibit the spreading of viruses, fungi, and bacteria!  Who doesn’t want some of that on their face huh?  Being so awesome, it has a low toxicity too.

Acrylates/C10-30 Alkyl Acrylate Crosspolymer:  Another formula stabilizer with a low toxicity.

Ethylhexylglycerin:  This is both a weak preservative and a skin moisturizer.  It can also be used in deodorant.  Low toxicity again people.

Hexylene Glycol:  This is another surfactant and general formula helper.  Its also used for fragrance purposes.  It has a low toxicity score which is fantastic

Dimethicone:  This is a popular primer ingredient.  Used in pore/oil fighting primers (like Porefessional), it seals the skin.  This keeps in moisture, without allowing it to surface and look like oily skin.  However, because this is pore filling, it makes the skin more susceptible to blackheads and breakouts, ew.  Oh, and it has a medium toxicity so booo.

Aloe Barbadensis Leaf Juice:  This is aloe vera juice, the last thing I thought could pose an issue but it has some contestation around it.  Basically, the outer part of the leaf can be an issue as it contains aloin, a cancer-causing compound.  However, it seems to be a problem more for ingesting it, rather than having a small amount of it in a primer.  Also, this only matters if the whole leaf is even in this formula and if it has been decolorized.  Decolorization filters the juice with activated charcoal and can apparently help get rid of basically all the aloin (read here for more info on this).

I don’t think this is a huge issue as it has a low to medium toxicity score depending on whether it is decolorized or not.  There also isn’t a huge amount of this in the formula, seeing how far down the ingredients list it is.

Tocopheryl Acetate:  This is an anti-oxidant and a moisturizer.  This is going to help give radiant skin, and help fight free radical/environmental damage.  This does, however, have a medium toxicity score :(.  This may also not be great for those with allergies or sensitivity.  I seem to be fine with it in this formula, but always remember to patch test.

Caprylic/Capric Triglyceride:  This is another one of those snazzy fragrance, moisturizing duos!  It has a low toxicity.

Tropaeolum Majus Flower/Leaf/Stem Extract:  This is another moisturizing, antimicrobial cool guys.  It comes from a flower too which is pretty neat.  Low toxicity y’all.

Aminomethyl Propanol:  This helps to stabilize the pH levels of the formula as well as being a “molecular weight buffering agent”.  Take from that what you will, it has a medium toxicity score, which I’m not cool with.  However, as it is in such a small amount, I am going to assume it is fine.

Disodium Edta:  I copied what this one does straight off the EWG database because I can’t science.  EDTA (ethylenediaminetetraacetic acid) is a chelating agent, used to sequester and decrease the reactivity of metal ions that may be present in a product.  Make of that what you can, this has a low toxicity 

Panthenol:  This is an ingredient that is a form of vitamin B5.  It is used as a moisturizer, conditioning agent and for antistatic properties.  It can be animal derived, but for this formula, will be plant or synthetically derived.  Low toxicity

Tocopherol:  This is a moisturizer, anti-oxidant and fragrance compound with a low toxicity score.

Pantolactone:  My goodness we have another moisturizer, I didn’t know there were so many moisturizers!  Low toxicity too yay!

Citric Acid:  This is going to be an incredibly gentle, low, low dose exfoliant.  It will help with anti-aging, skin radiance and bacteria fighting. This also has a low toxicity score.  The use of this is restricted in Canadian cosmetics.  I suspect because it is an acid if too much is used could potentially hurt the skin.

3-Aminopropanol:  I looked through some websites and couldn’t find how this ingredient relates to cosmetics.  The science websites seem to think it’s something to be really careful with, but they will be using it at intense concentrations.  This means that I’m pretty sure this is absolutely fine.  If you’re unsure, again, spot test!


All in all, I am amazed by the fact that the vast, vast majority of products had such a low toxicity rating.  I really was expecting for this product to do far worse, as it’s not marketed as being one of those “good for you” products.  This was a really nice surprise I reckon.  I am impressed by the number of moisturizing ingredients in this.  It shows that the moisturizing name isn’t a lie; this really will hydrate the dryest of dry skin!

I am happy and impressed with this product.  Check it out at Sephora here

I know this was a big read, so thank you for getting to the bottom of it.
