Collagen Cream Recipe

Collagen creams are very popular nowadays, particularly for the fairer sex, as our skin is constantly battered by everyday stresses and urban pollution. These creams delay the aging process through collagen production and repair damaged skin caused by acne or laser hair removal.

This recipe from the Bulk Actives site is adapted from the formulation of Carol Demas, the author of Make Your Own Effective Cosmetic Treatments and Sunscreens. Its main ingredient is hyaluronic acid, an anionic, nonsulfated glycosaminoglycan that reduces fine lines and wrinkles while brightens
skin complexion. Hyaluronic acid is coupled with ferulic acid, which is an antioxidant and offers broad spectrum sun protection. For ferulic acid to be dissolved easily, fragrance grade dipropylene glycol is included as a solvent. Dipropylene glycol also benefits the recipe for its emollient property. Vitamins to nourish the skin are also added like ascorbic acid (Vitamin C) and tocopherol (Vitamin B). This recipe is specifically formulated for sensitive skin types.

Fragrance Oil Base with Dipropylene Glycol

Dipropylene glycol is a popular solvent and carrier for perfumes and essential oils. Its popularity rests with the fact that it is odorless, colorless, and non-toxic. Propylene glycol molecules bind with those of perfume oils which slows its dispersion rate. This can be worked by controlling the glycol’s ratio to dilute or strengthen the fragrance. What’s more, dipropylene glycol is very easy to use and can be handled by home perfume makers or by commercial formulators alike.

There are two types of propylene glycol: the industrial and the fragrance grade. Choose the latter because it is the only grade appropriate for skin and cosmetics use. It is noncomedogenic, making it suitable for people with sensitive skin. Ideally, the ratio of perfume base for essential oils to dipropylene glycol is 3:7.

Ingredients and Materials:

1 oz. essential oil/s of choice

2 ¼ oz. dipropylene glycol, fragrance grade

¼ oz. vodka or perfumer’s alcohol

4 oz. amber or opaque glass bottle, airtight

Method:

Mix the essential oils, dipropylene glycol, and perfumer’s alcohol or vodka in a beaker. Stir well until mixture is well blended. Pour into the amber bottle until almost filled and close tightly. Shake the bottle gently and overturn it at least ten times to ensure thorough mixture of the ingredients. Then store the
bottle in a cool, dark place for a month or longer. This curing period ensures that the perfume will get a strong scent and that all the elements will blend well. After the curing period, perfume base is ready to be diluted with perfumer’s alcohol as eau de toilette, or mixed in formulations of massage oils, lotions, and incenses.
