Here are some helpful calculators and conversion utilities to assist you in your cosmetic formulating.
Use this calculator to convert between imperial (US) ounces/pounds and metric grams/kilos weights.
Enter one of the amounts to convert from, then click "Calculate." Click "Clear" to start over.
Liquid Volume Converter
We always recommend cosmetic formulating be done by weight, not volume. But when you are working with volumetric measurements, use this calculator to convert instantly between gallons, liters, pints, cups, teaspoons, and even drops, from imperial (USA) volume and metric volume units. Note, for ease of use we have rounded off: 30ml = 1 ounce and 20 drops = 1ml (the metric equivalent, rather than the pharmaceutical standard). Since dropper openings will vary and droplet sizes are also affected by the surface tension of the fluid itself, numbers of drops are, at best, an estimate.
Choose the measure to convert from and the one to convert to,
then enter the amount to convert, and click on Convert.
This will calculate the volume of a Stock concentrate (example, Lactic Acid 90%) needed to add to a formula or another product (like a lotion base or water) to achieve another specific concentration (example, a 20% Lactic Acid solution). To use this calculator, you need to know how much you want to make, the concentration you want to have in the final product, and the concentration of the Stock solution you will be using. Enter the total amount you want to make, the concentration you want in the end product, and the concentration of the Stock solution, then click 'Calculate', and the calculator will tell you the amount of 'base' to use (water, lotion, formula etc.) and how much of the Stock solution to add to it to make the amount of product you want in the desired concentration.
The calculator doesn't need to know if you are using teaspoons, tablespoons, ounces, milliliters, grams or kilos; it is simply performing a mathematical calculation. If you are working in ounces, then the results are to be interpreted in ounces, if working in grams or milliliters, then what is displayed will be those. Do not mix and match!
Enter a value for Fahrenheit or Celsius, then click "Calculate".
Date Conversion / Lot Number Generator
Use this Date Conversion utility to assist you in creating Lot Number labeling for your products. This enables you to create a Lot Number that you can easily identify. For example, the first batch of product made on January 2, 2016 might be assigned this number: 1600201 (16=year, 002=day number, 01=batch number of the day). The calculator generates a sample Lot Number for you.
Enter any Date (mo day year) or Day Number (for this year) you wish to calculate. Note, today's date is always the default and is displayed automatically (unless you have had this page displayed overnight, in which case, click "Reset" to refresh the input).

I am new at making lotion and Jen has been so helpful and courteous with all my questions and the shipping time was incredibly fast! Thank you for all you do...your customer service is fantastic!
Excellent service, excellent pricing. Placed an order for 21 items and its on the doorstep in Australia in 5 business days. I do custom formulations and by buying on the Lotioncrafter website i saved a lot of time and money.

I'm really impressed with your speed in packaging and shipping my order. I got a ship-confirmed email within 2 hours of ordering and received the order the next day! Other vendors I patronized days earlier did not ship my order for several days and their shipping charges were so high too. Thanks!
Jenny is a very helpful technical person. I was only looking for something simple such as sodium hydroxide and shampoo thickener. And Jenny went all the extra miles explaining over the phone for these two ingredients. She is a very, very helpful and knowledgeable person. Thank you Jenny!!!

I just wanted to say that from my very first time ordering from lotioncrafter in 2014 & now 2016 this company has been consistently amazing. I have never had an issue with anything at all. Every order is shipped promptly (without paying ridiculous fee) ingredient information is readily available (not hidden), quality is unquestionable, and should you need to contact someone you will get a response immediately ...only thing I could cry about is I wish they carried serecite, pigments, sci, smc taurate, ... etc so I could only order from them...which is unreasonable on my part. Truly a reputable high quality supplier
