sodium hydroxide has a ph of ? and is a
12.5-13.5 is a lye relaxer
has a ph of 12.5-13.5 ,is a no -mix,lye relaxer
lithium hydroxide and potassium hydroxide
9.6-10.0 thio relaxer,no lye relaxer
ammonium thioglycolate
6.5-8.5 low ph relaxer,no lye relaxer
ammonium sulfite/ammonium disulfite
active ingredient in all hydroxide relaxers
hydroxide ion
hydroxide realxers are not compatible with
thio relaxers,permanent waving or soft curl perms
hydroxide relaxers permantly straighten hair,breaks hairs disulfide bonds during processing and coverts them to lanthionine bonds when rinsed from hair
lanthionization
neitralization of hydroxide relaxers is an acid-alkali neutralization reaction that neutralizes(deactivates) the alkalineresidues,also lowers the ph balance of hair and scalp
hydroxide neutralization
ionic compounds formed by a metal combined with oxygen and hydrogen
metal hydroxide realxers
uses the same ammonium thioglycolate(atg) that is used in permanent waving ,but at a higher concentration and a higher ph (above10)
thio relaxers
does not involve oxidation or rebuilding disulfide bonds
hydroxide neutralization
sodium hydroxide relaxers are commonly called
lye relaxers
advertised and sold as 'no mix lye" relaxers
lithium hydroxide and potassium hydroxide relaxers
these relaxers straigten hair completely with less scalp irritation than other hydroxide relaxers
guanidine hydroxide realxers
low ph relaxers
sulfite and disulfites
base relaxers require
protective base
no-base relaxers dont require
protective base
rinse with
warm water
can also be called a jeri curl
soft perm
a neutralizer is used with
thio relaxers
