Three complete formulas, ready to make
Each one comes with a full ingredient table, exact weight percentages, a step by step method, an ingredient by ingredient breakdown, and honest substitutions for anything you cannot source.
Botanical Luxury Body Oil
A fast absorbing, dry touch body oil built on an ester base, so it seals in moisture without the grease.
Brown Sugar Glow Scrub
An oil suspended sugar scrub that polishes without stripping. Two phases, and a texture you can tune.
Botanical Lip Butter Balm
A vegan wax and butter system with real staying power, plus notes on converting it to a stick format.
Built like a formulator's document
Most DIY content tells you to add a few drops of something and hope for the best. That is not how products get made.
Exact percentages
Real weight percentages for every ingredient, summing to 100. No drops, no spoons, no guessing.
Full INCI names
Every material listed the way suppliers label it, so you know exactly what you are buying.
The reasoning, left in
Why oils seal instead of hydrate. Why the scrub is 60% sugar. Why two waxes, not one.
Smart substitutions
What each ingredient is doing, and what you can swap it for when you cannot source it.
A troubleshooting page
Grainy balm, separating scrub, greasy oil. The cause, and exactly what to change.
Water free on purpose
No preservatives, no pH meter, no stability testing. Learn the craft before you carry the risk.
Hi, I am Ashley. M.Sc. Chemical Engineering.
I write the documents I wish someone had handed me when I started: exact, honest, and fully explained, with the reasoning left in rather than stripped out. First Formulas is a small, real sample of how I work, so you can see the difference before you go deeper.
