Understanding Product Volume vs. Weight

You've asked about the volume (ml) of the liquid products you received, which were measured by weight (grams), and whether 1 gram equals 1 ml for these items.

To convert weight (grams) to volume (milliliters), you need to know the density of each specific substance. Density is a physical property that relates mass to volume (Density = Mass / Volume). For pure water, 1 gram is approximately equal to 1 ml, but for most other substances, the density is different, meaning 1 gram will not equal 1 ml.

Based on the information available, the specific density values for the products you received are not provided in the product descriptions. Therefore, it is not possible to accurately calculate the exact volume for each item based solely on the weight you received.

Regarding the items you listed:

• Silky Serum Base Plus
• Butylene Glycol
• Panthenol (Vitamin B5)
• Phenoxyethanol SA
• Glycerin (Vegetable)
• Ethoxydiglycol

While some substances like Butylene Glycol, Glycerin, and Ethoxydiglycol are liquids, their densities are typically different from water. For example, Glycerin is denser than water, so 1 gram would be less than 1 ml. Butylene Glycol and Ethoxydiglycol also have densities different from water.

For Panthenol (Vitamin B5), while it can come in liquid forms (solutions), it is also commonly available as a powder (like the product description for ID 111 indicates). The density would depend on the specific form and concentration of the liquid you received.

As the staff response mentioned, products are sold by weight because it provides a more accurate and consistent measurement for formulation. Weight does not change with temperature, whereas volume can fluctuate with temperature changes.

For the most accurate results in your formulations, it is recommended to continue using the weight measurements provided for these products.
