This type of soap bar is known as the hand, face, beauty soap bar type. It is also known as a 'standard' size. The 'standard' type pertains to its dimensions and weight as well. The standard soap bar is three inches in length, two inches in width, and one inch thick. The bar contains six cubic inches of soap and weighs 3 to 3.25 ounces. The standard soap bar is not a square but a rectangle with length slightly larger than the width. This size and weight are a perfect holding soap as it fits neatly into the palm of the hand.
Bath/Body/Family/Industrial/Laundry/Pet Animal Soap Bar
This bar is 4 to 6 inches in length by 3 inches in width, and 1 to 1-1/2 inches in thickness. These bars weigh 4.5 to 8 ounces or 128 to 227 grams. The larger sized bars require and use more soap formula. These larger bars are used for animal-care soap for pets, horses, and any livestock. These bars are also used as industrial and laundry soap bars.
Because of the generous size of these soap bars, we recommend creating a silicone mold 6 to 9 soap cavities per mold.
Guest/Hotel/Sampler Soap Bar
This bar is 1 to 2 inches in length by 1 to 1-1/4 inches in width, and 1/4-inch thickness. The weights of these soap bars are less because they are smaller bars in size and weigh anywhere from a half ounce (14 grams) to two ounces (57 grams). This weight is excellent for creating multi-soap bar sample packs of your product lines. The weight of the soap bar is also excellent for individual use for hotels/motels/bed and breakfast, and as aromatic sense bath fizzes which dissolve quickly releasing your perfect scents.
Look at two rectangle soap bars, one with square corners and the other with rounded corners. The rectangle bar with square corners looks larger, fuller, the maximum size of your soap bar.
The rectangle soap bar with rounded corners looks more inviting, softer, more pleasing, and even more refined.
Part II: If You Advertise the Soap Bar Weight
Product Labelling Has Regulations
When a product is labelled, it must have, at least, the net weight on the package, say ninety grams; the word 'soap' to identify the contents; along with an identifying name of a fragrance; and the name and the address of the business.
Should the soap bar weigh a little more than what the package says, that is acceptable to the labelling laws and FDA regulations. It is when the contents weigh less than the weight on the label, the company will face fines. As we all know, it is a priority to get as close to the weight as we can without being under the labelled weight, but not so much more as it costs more to manufacture the soap bar.
Technically, you do not have to list the ingredients. You must label it "SOAP"; how it weighs; and where to find your company.
You can list fragrance as just "fragrance", or "fragrances". You can list any ingredients that are less than 1 percent of the total formula, in any order, at the end of the list of ingredients.
