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).
So that our staff may enjoy the extended July 4th holiday with their family and friends, Lotioncrafter's offices will be closed on Monday, July 4th. We will reopen on Tuesday, July 5th. During this time, we will not be returning phone calls or email messages. Shipping will resume on Tuesday. Have a safe and Happy 4th of July!
Love the new website!
Jen is such a pro when it comes to prompt & courteous customer service, plus shipping rates are as reasonable as possible these days - not like some sites that just gouge you.
I'm a small customer, but always feel that my business is valued.
Just received my latest order from Lotioncrafter and am, as usual, thrilled with it. Lotioncrafter's products and service are so superior to any other vendor that I can't imagine ordering from anyone else. Thank you so very, very much!
I placed my order on Monday, July 12th and received the order on Wednesday, July 14th. I was really pleased with the quick arrival, the care that each item was packed with and the very nice and useful items Jenny sent with my order as a thank you.
So many thanks for your efficiency, kindness, and great products,
My biggest dilemma is that I live in Hawaii and finding reputable and affordable suppliers is near impossible, and once you locate one the shipping is out of this world ($50+ for shipping alone normally); when I found your website I was hopeful. Not only did you have the refined Shea Butter I was looking for, but you had everything else too! And the shipping was VERY affordable. I received my order 1 day sooner than I expected it (and shipping to Hawaii normally takes longer than shipping 'locally' within the continental US). I couldn't be more pleased with everything that you have to offer. I will definitely be ordering again, you have a customer for life!
My products are always packaged well and arrive very quickly! Nice products too.
