What the register lists it for
These are the uses the European Commission’s CosIng register lists for Petrolatum in any cosmetic, hair roles first. They say why a maker might add it, not what it does in one formula, and they aren’t a safety rating.
- Antistatic
-
Cuts the static that makes dry hair fly away. Many conditioning ingredients carry this role too, because both work at the hair’s surface.
Register definition: “Preventing and/or reducing static electricity by neutralising electrical charge on surfaces.”
- Emollient
-
Oils, butters and similar ingredients that make a surface feel soft and smooth. On hair they coat the strand; many plant oils carry this role.
Register definition: “Acting as lubricants on the skin surface providing the skin with a soft and smooth appearance.”
Where it sits on each label
US labels list ingredients from most to least, except that those at 1% or less may follow in any order. A name near the top is a large part of the formula. A label doesn’t mark where the 1% point falls, so further down, the order says little about how much is in it.
- Stylers 1 label First five names: 1 of 1 Stylers without it
- Protein treatments 1 label First five names: 0 of 1 Protein treatments without it
Every label, product by product (2)
- Aussie Miracle Curls Frizz Free Curl Cream Styler 4th of 25 names
- ApHogee Keratin 2 Minute Reconstructor Protein treatment 8th of 44 names
Each line runs from the first name on a label to the last; a dot is where this ingredient sits. Makers change formulas now and then; if the list on your bottle differs, go by your bottle.
