Contents that should be labeled are set by law as obligation. These texts have to be printed directly onto the packaging of the product. Also, when there is a box for the product to be put in and the texts that are printed on the packaging cannot easily be seen through the box, the texts with same contents have to be stated outside of the box as well.

Q5.Why do cosmetics label all contained ingredients?
The Pharmaceutical Affairs Law was revised in 2001. Following the new law, not only the ingredient that were listed to be required of labeling but all contained ingredients are required to be labeled.
Since this law was set, companies are required to work even harder on are needed for the safety of their products. Furthermore, labeling all contained ingredients have an important role as reference information for customers to select products and use them. Ingredients are stated in the decreasing order of the formulated amount. However, ingredients’ that are formulated for less than 1% can be listed in not particular order.
Q6.What kind of size and material container are available?

The purpose of formulating preservatives is to prevent product being deteriorate in its quality, scent, and growing mold which are possible influence caused by microbe accidently contaminated through the whole process of cosmetic manufactured in a factory, delivered to customers’ hand, and till the product is used up. The stability of cosmetcis are stated in “Law regarding securing the quality, effectiveness, and safety of medicine and medical equipments” (shorten as Law of medicine and medical equipment, Previous: the Pharmaceutical Affairs Law). “After manufacturing or exporting, products’ characteristics and quality have to be stable for more than three years under correct storage condition. And for products that have the possibility that the product quality will change, those have to label the expiration date of use”. Preservatives are contained in order to meet this law and to sustain product safety.
Common preservatives used in cosmetics are paraben. There are several types of pearaben such as methylparaben, ethylparaben, propylparaben, and butylparaben. They are formulated according to the purpose (to protect water soluble component or oil soluble component) and base material (for example, whether it is a toner or a cream). These parebens are reliable preservatives that have been used in cosmetics for a long time. Recently there are cosmetics that are created under concept of pareben free these days.
In case of formulating paraben free products, we achieve the safety and stability of our cosmetics by manufacturing in c clean space with less bacteria and using other alternative stabilizer that supplement antimicrobial activity. For OEM cosmetics, we will propose suitable solution for the formulation.
Q8.What are Additive-free Cosmetics?
Additive-free cosmetics are cosmetics that does not contain certain types of additives. The current conditions is that additive-free cosmetics are created under each company’s own standard because there are no concrete standard for these products. For example, cosmetic “A” which don’t contain artificial coloring and cosmetic “B” which doesn’t contain preservatives, both can be called as “additive-free cosmetics”. Cosmetec Japan offer support for creating your additive-free cosmetic product according to our customer’s needs.
Q9.What is organic cosmetics?
Organic cosmetics are “cosmetics made mainly by formulating with nature-derived ingredients without using any or use only a minuscule amount of chemical ingredients” Organic cosmetics are winning strong popularity for its impression that they are natural as it can be. The standards for organic cosmetics differs from area to area but France, Germany, and Australia monitor this standard in the national level. Therefore, it is extremely difficult to call skin care products as organic. However, there are no such concrete legal standard to acknowledge organic products in Japan so products are created under control of standards set by each company in this current condition. Us Cosmetec Japan offers support by considering your desire for example. We can developing substrate that are nature-derived as much as possible or proposing product concepts formulating plans that are approved as organic.
Q10.What are the differences between ultraviolet absorber and ultraviolet scattering agent?
Ultraviolent absorber prevents ultraviolet to penetrate to skin by absorbing ultraviolet in a scientific system and transform them into energy such as heat or infrared light. Because of this absorbent's characteristic of being translucent, it is not likely to set white on skin. However, it can cause irritation for some people.
Ultraviolet scattering agent prevent ultraviolet to enter skin by literally scattering and reflecting ultraviolet in a physical system. Ultraviolet scattering agent mainly contains white inorganic powder such as titanium oxide, zinc oxide. Sun screen that uses ultraviolet scattering agent used to have a tendency of setting white on top of skin which made makeup look heavy. However today, sunscreen that doesn’t set white on skin have been developed using finely grind ultraviolet scattering agent. For OEM cosmetics, our company will suggest UV formulation that suits the concept of your product.
Q11.What are the differences between SPF and PA?
There are two types of ultraviolet ray that reaches the surface of the earth, “UV-B” that have short wavelength, and “UV-A” that have long wavelength. UV-B cause inflammation like getting burned and make skin darker after few days. UV-A have a effect of making skin darker right after skin being exposed to sun light, and it reaches up into dermic layer of skin which deprive skin of plumpness and cause discoloration, wrinkles, and flabbiness.
“SPF” and “PA” that are shown stated on the sunscreen products are the guidelines that shows the level of capability on preventing two ultraviolet rays UV-B and UV-A.
SPF is shorten for “Sun Protecting Factor” and it is the number that shows the effect on preventing UV-B which cause sun burn (skin becomes red from sun burn). For example, sun screen that has SPF30 in it means that it can prevent skin getting red for 30 times more hours in the sun than when applying nothing, The more higher number means that it has more protection from UV-B, and when the SPF ability of protection is higher than 50, it is stated “SPF50+”. PA is shorten for “Protection Grade of UV-A” and it shows the preventing ability for UV-A which cause sun tan (sunburn that darken skin). The capability used to be evaluated in 3 levels of “PA+ (effective)”, “PA++ (very effective)”, “PA+++ (extremely effective)”, however, Japan Cosmetic Industry Association created and settled a standard on January,2013 which evaluate PA level adding “PA++++ (tremendously effective)”.
The more + it has, the more UV-A preventing effect it contains. There are people who have an impression that ultraviolet protection is needed only during the summer. However, the amount of UV-A does not have a dramatic change over seasons and it has a characteristics of passing through clouds and windows. Therefore, ultraviolet protection is necessary through out the year even on a cloudy day and inside the house on a sunny day. Our company will be happy to propose the suitable OEM cosmetic product for you.
Q12.What is carry over?
Carry over are ingredients that are “slightly contained in raw materials that does not perform any effect when formulating cosmetics” for the purpose of stabilizing antioxidant and preservative formulated to stabilize raw material when extracting ingredients from them. These ingredients are not legally obliged to label as ingredients.
For example, when formulating plant extracts, depending on the extract, they may contain very small quantity of paraben for preservation purpose that was applied when it was still raw material. It was not formulated as one of the cosmetic ingredients during the manufacturing process, however, a paraben are slightly contained by formulating those extracts. These ingredients are called carry over ingredients.
