I have been using natural preservatives effectively in my cosmetic formulations for over 10 years. Here are some common and important questions and points that every cosmetic formulator and product maker should consider with natural preservatives.
When I refer to cosmetics, I am referring to body, hair and skin care products.
Preservatives in cosmetics are a topic with many differing and controversial opinions. The one common belief in selling products is that they must be properly preserved and safe to use.
Regarding the preservatives presently used in cosmetics, you will find opinions and research that differ and even contradict each other. For example, using alcohol as a preservative, you will find research on why it is good for the skin and research on why it shouldn’t be used in body, hair and skin care products. It is the same with how we eat. Some research says drinking a little alcohol is good for you and other research says it is not good for you.
To formulate a leave-in hair conditioner, you need to know the purpose and how it is used on the hair. The conditioner is applied after you shampoo and condition. Generally, you apply to towel-dried hair before detangling and styling. This will provide extra moisture and an easy comb through.
The conditioner should always be light in consistency, almost like a hair milk. It can be used by all hair types. The added moisture is excellent for maintaining curls. It does not build-up on the hair. It should leave the hair feeling soft, curls managed, shiny and sheeny.
