SD-Alcohol 40B

SD (Specially Denatured) alcohol 40 is a type of denatured alcohol used in cosmetics and skincare products. It is mainly used as an anti-foaming agent, astringent, antimicrobial agent, and a solvent
is ethanol that has additives to make it poisonous, bad-tasting, foul-smelling, or nauseating to discourage its recreational consumption. It is sometimes dyed so that it can be identified visually
Denaturing alcohol does not chemically alter the ethanol molecule and it is mainly obtained from a variety of biomass materials called feedstocks (the raw materials used to make a product). Ethanol feedstocks include grains and crops with high starch and sugar content such as corn, sugar cane, and sugar beets among others
It is also used in cosmetics and personal care to decrease the "dry down" time of a product
All SD alcohols are named such due to the Denaturant used in them which is intended to make the alcohol undrinkable as it will make a person ill intentionally
The Denaturant varies by the alcohol number, so 40B uses tert-Butyl alcohol
40-B has the least amount of denaturants used in comparison to all other SDA formulas
As an astringent, SD alcohol 40 causes the skin to contract after topical application
It is a controversial ingredient. It's a great solvent and makes cosmetically elegant, light formulas but at best it's skin-drying, at worst it's skin-barrier damaging, ALTHOUGH, we use in only in our Hair Mask as a solvent, fast evaporation vehicle for the Natural oil mixes to be easily applied to your hair, and as antimicrobial
