Comedogenic Ratings

Some Oils, Butters and Waxes Clog Pores, Others Dont

Just an FYI for when your shopping around

com·e·do·gen·ic , (kämədōˈjenik) is another one of those words that your computer might put a squiggly red line under. Its actually a medical /cosmetic term to describe the tendency of something to clog pores and cause breakouts. Comedogenic numbers or ratings are values between 0-5 assigned to oils, waxes, butters, botanicals, etc. to measure their relative tendency to clog pores. Everyone has a different interaction with oils depending on pore sizes and skin type, so just because an oil has a rating of 4, doesn't mean that it will clog your pores, it just means its more likely to clog your pores than oils with ratings of 1,2 or 3. 

 

Side note.... When looking at natural 100% saponified SOAP, things are not as simple. You must consider the oils that are converted into SOAP and Glycerin during the saponification process and the ones that are not. The amount of excess oils in the final product depends on the saponifiable and non-saponifiable ingredients and triglyceride (oil) / sodium hydroxide ratios. For example, our SOAP base is made with coconut oil, avocado oil and shea butter and our ratios yield 6% excess oil/butter in the final product. Much of this excess consists of non-saponifiable portions of shea butter and avocado oil. Anyways, a better understanding of saponifiable and non-saponifiable ingredients is required to fully evaluate natural SOAP. However, this list is great for lotions, moisturizers, salt/sugar scrubs, or any other product that isn't natural SOAP. (Most people use this information to decide on face products, as the face is more prone to pore clogging.) 

 

Here is the relative scale  

0 - Will Not Clog Pores
1 - Low
2 - Moderately Low
3 - Moderate
4 - Fairly High
5 - High

Johnson's Baby Products Contain Allergens, Immunotoxins and Inflammatory Ingredients

January 07, 2016

johnsons head to toe

With a relatively new push from Johnson's to appear 'free of toxic chemicals', it's important to realize marketing strategies are not entirely honest. Although SOME of Johnson's products are Phthalate and Paraben free, they still contain ingredients known to cause acute and chronic skin allergies, inflammation and skin damage. Take a look at some information we compiled in hopes to motivate more people to start investigating individual ingredients in the products they use.
